Definitions

  • the invention is directed to devices, systems, and methods for improving the function of a heart valve, e.g., in the treatment of mitral valve regurgitation.
  • the heart (see FIG. 1 ) is slightly larger than a clenched fist. It is a double (left and right side), self-adjusting muscular pump, the parts of which work in unison to propel blood to all parts of the body.
  • the right side of the heart receives poorly oxygenated (“venous”) blood from the body from the superior vena cava and inferior vena cava and pumps it through the pulmonary artery to the lungs for oxygenation.
  • the left side receives well-oxygenation (“arterial”) blood from the lungs through the pulmonary veins and pumps it into the aorta for distribution to the body.
  • the heart has four chambers, two on each side —the right and left atria, and the right and left ventricles.
  • the atria are the blood-receiving chambers, which pump blood into the ventricles.
  • the ventricles are the blood-discharging chambers.
  • the synchronous pumping actions of the left and right sides of the heart constitute the cardiac cycle.
  • the cycle begins with a period of ventricular relaxation, called ventricular diastole.
  • the cycle ends with a period of ventricular contraction, called ventricular systole.
  • the heart has four valves (see FIGS. 2 and 3 ) that ensure that blood does not flow in the wrong direction during the cardiac cycle; that is, to ensure that the blood does not back flow from the ventricles into the corresponding atria, or back flow from the arteries into the corresponding ventricles.
  • the valve between the left atrium and the left ventricle is the mitral valve.
  • the valve between the right atrium and the right ventricle is the tricuspid valve.
  • the pulmonary valve is at the opening of the pulmonary artery.
  • the aortic valve is at the opening of the aorta.
  • ventricular diastole i.e., ventricular filling
  • the aortic and pulmonary valves are closed to prevent back flow from the arteries into the ventricles.
  • the tricuspid and mitral valves open (as FIG. 2 shows), to allow flow from the atria into the corresponding ventricles.
  • the tricuspid and mitral valves close (see FIG. 3 )—to prevent back flow from the ventricles into the corresponding atria—and the aortic and pulmonary valves open—to permit discharge of blood into the arteries from the corresponding ventricles.
  • the opening and closing of heart valves occur primarily as a result of pressure differences.
  • the opening and closing of the mitral valve occurs as a result of the pressure differences between the left atrium and the left ventricle.
  • the mitral valve opens, allowing blood to enter the ventricle.
  • the ventricle contracts during ventricular systole, the intraventricular pressure rises above the pressure in the atrium and pushes the mitral valve shut.
  • the mitral and tricuspid valves are defined by fibrous rings of collagen, each called an annulus, which forms a part of the fibrous skeleton of the heart.
  • the annulus provides attachments for the two cusps or leaflets of the mitral valve (called the anterior and posterior cusps) and the three cusps or leaflets of the tricuspid valve.
  • the leaflets receive chordae tendineae from more than one papillary muscle. In a healthy heart, these muscles and their tendinous cords support the mitral and tricuspid valves, allowing the leaflets to resist the high pressure developed during contractions (pumping) of the left and right ventricles.
  • chordae tendineae become taut, preventing the leaflets from being forced into the left or right atria and everted. Prolapse is a term used to describe this condition. This is normally prevented by contraction of the papillary muscles within the ventricle, which are connected to the mitral valve leaflets by the chordae tendineae. Contraction of the papillary muscles is simultaneous with the contraction of the ventricle and serves to keep healthy valve leaflets tightly shut at peak contraction pressures exerted by the ventricle.
  • the leaflets coapt at the opposing medial and lateral sides of the annulus are called the leaflet commissures, and are designated in FIG. 4 and in other Figures as CP(denoting the posterior commissure) and CA (denoting the anterior commissure).
  • Valve malfunction can result from the chordae tendineae (the chords) becoming stretched, and in some cases tearing. When a chord tears, the result is a leaflet that flails. Also, a normally structured valve may not function properly because of an enlargement of or shape change in the valve annulus. This condition is referred to as a dilation of the annulus and generally results from heart muscle failure. In addition, the valve may be defective at birth or because of an acquired disease.
  • mitral valve dysfunction can occur when the leaflets do not coapt at peak contraction pressures.
  • FIG. 5 shows, the coaptation line of the two leaflets is not tight at ventricular systole. As a result, an undesired back flow of blood from the left ventricle into the left atrium can occur. This condition is called regurgitation.
  • the leaflets do not form a tight coaptation junction because the dimensions of the mitral valve annulus, measured from commissure to commissure—CP to CA—and/or septal to lateral—S to L—change. The changed dimensions no longer create the anatomic shape and tension in which the leaflets coapt at peak contraction pressures.
  • the unhealthy annulus is dilated and, in particular, the septal-to-lateral distance is increased.
  • the shape and tension defined by the annulus becomes less oval (see FIG. 4 ) and more round (see FIG. 6 ). This condition is called dilation.
  • the shape and tension conducive for coaptation at peak contraction pressures progressively deteriorate. Instead, at peak contraction pressures, the leaflets do not coapt completely, and a gap forms between the leaflets. During ventricular systole, regurgitation can occur through this gap.
  • the ratio between the commissure distance and septal-to-lateral distance bears a relationship to the effectiveness of leaflet coaptation. If the septal-to-lateral distance increases, the ratio changes, and when the ratio reaches a certain value, regurgitation or the likelihood of regurgitation is indicated.
  • Mitral valve regurgitation can be an acute or chronic condition. It is sometimes called mitral insufficiency.
  • diuretics and/or vasodilators can be used to help reduce the amount of blood flowing back into the left atrium.
  • An intra-aortic balloon counterpulsation device is used if the condition is not stabilized with medications.
  • surgery to repair or replace the mitral valve is often necessary.
  • annulus can be reshaped with annular or peri-annular rings or similar ring-like devices.
  • the repair devices are typically secured to the annulus and surrounding tissue with suture-based fixation.
  • the repair devices extend over the top and over much or all of the circumference of the annulus and leaflet surfaces.
  • a physician may decide to replace an unhealthy mitral valve rather than repair it.
  • Invasive, open heart surgical approaches are used to replace the natural valve with either a mechanical valve or biological tissue (bioprosthetic) taken from pigs, cows, or horses.
  • the invention provides devices, systems and methods that reshape a valve annulus.
  • the devices, systems, and methods include an implant that is sized and configured to rest near or within the leaflet commissures of a heart valve annulus. In use, the implant contacts and outwardly displaces tissue to reshape the heart valve annulus.
  • the implant in use, may restore to the heart valve annulus and leaflets a more effective anatomic shape and tension. The more normal anatomic shape and tension are conducive to coaptation of the leaflets, which, in turn, reduces retrograde flow or regurgitation.
  • the implant restores function to the valve, without surgically cinching, resecting, and/or fixing in position large portions of a dilated annulus, or without the surgical fixation of ring-like structures.

  • the markers 68 identify a desired distance between them and the distal end of the sheath 60 , marking a space in which the implant 10 can freely expand without contacting tissue or anatomic structures within the atrium. Guided by the markers 68 , the loop 66 can be dropped into the annulus a desired distance beyond the distal end of the sheath 60 , as FIG. 27A shows.
  • the sheath 60 can be withdrawn to free the implant 10 for expansion (see FIG. 27B ). While tethered to the guide wire loop 66 , the implant 10 opens within the left atrium—first one strut, then the other—as the sheath 60 is withdrawn, as FIGS. 27C and 27D show.
  • both legs of the guide wire loop 66 can be advanced proximally in tandem through the sheath 60 (see FIG. 27E ).
  • the wire loop 66 applies force to the struts 12 and brings them together (see FIG. 27F ). This places the implant 10 in a compressed, elastically loaded condition. Proximal advancement of the legs of the wire loop 66 also draws the implant 10 in this condition snuggly against the distal end of the catheter 58 for greater control, as FIG. 27F shows.
  • the catheter 58 can be advanced under image guidance to place the implant 10 within the annulus. Manipulation of the catheter 58 will bring the struts of the implant into desired alignment. Subsequent distal advancement of the legs of the wire loop 66 (see FIG. 27H ) allows the struts of the implant 10 to be elastically unloaded and brought into contact with the surrounding tissue. Anchoring structures or mechanisms associated with the struts 12 can also be placed into desired contact with adjoining tissue below and/or above the plane of the annulus. The legs of the wire loop 66 can be manipulated to pull the struts 12 together and/or allow them to separate, until the desired orientation and tissue contact in and about the annulus are achieved.
  • one leg of the wire loop 66 can be pulled to release the implant from the guide wire 64 (see FIG. 27I ).
  • the implant 10 is allowed to fully unfold and seat within the annulus.
  • a guide loop 66 can be used to deploy open annular implants as well as closed annular implants. As shown in FIG. 28A , a single guide loop 66 can be threaded through an open annular implant 10 of the type shown in FIG. 13B . Or, as shown in FIG. 28B , two guide wire loops 66 A and 66 B can be threaded through an inter-locking implant of the type shown in FIGS. 13D and 13E . In this arrangement, the first guide wire loop 66 A can be manipulated to position the struts 12 of the implant within the annulus, as just described. The second guide wire loop 66 B can be separately manipulated to pull the rails 14 together for interlocking, once the struts rest in a desired manner in the commissures.
  • FIGS. 15A to 15 E show elastic implants 10 that can be folded about cusps 20 .
  • the folding allows the implant 10 to be conveyed into the left atrium within a sheath 60 of an implant delivery catheter 58 with a delivery profile that not only constitutes a side-to-side collapsed condition—which minimizes the delivery profile diameter—but also constitutes a lengthwise folded condition—which minimizes the delivery profile length.
  • FIGS. 30A to 30 D illustrate the deployment of a symmetrically folded elastic implant 10 of the type shown in FIGS. 15A and 15B .
  • the implant 10 is constrained in a symmetrically folded and collapsed condition within the sheath 60 , as FIG. 30A shows.
  • the struts 12 form the leading end of the implant.
  • a push rod 62 in the catheter 58 includes a gripping mechanism 70 that holds the folded implant 10 by the cusps 20 .
  • the push rod 62 is advanced to expel the implant 12 from the sheath 60 , both struts 12 first.
  • the folded implant 10 is aligned with coaptation line generally equidistant from the commissures, with the struts 12 oriented to face the commissures (the delivery catheter 58 has been previously introduced trans-septally into the left atrium, as already described).
  • Manipulating the push rod 62 advances the implant 10 , both struts first, from the sheath 60 .
  • Connecting the push rod 62 to the implant 10 allows the implant 10 to be translated and rotated and retracted during deployment. Freed from the sheath 60 (see FIG. 30B ), the implant 10 begins to unfold along the cusps 20 , and the struts 12 draw apart toward the commissures.
  • the implant 10 Prior to release of the cusps 20 from the gripping mechanism 70 , the implant 10 can be manipulated to assure that anchoring structures or mechanisms associated with the strut are placed into desired contact with adjoining tissue below and/or above the plane of the annulus. The gripping mechanism 70 can then be activated (see FIG. 30D ), releasing the implant 10 .
  • FIGS. 31A to 31 E illustrate the deployment of an asymmetrically folded elastic implant 10 of the type shown in FIGS. 15D and 15E .
  • the implant 10 is constrained in an asymmetrically folded and collapsed condition within the sheath 60 , as FIG. 31A shows.
  • the gripping mechanism 70 holds one, but not both of the cusps 20 . This is because the height of the cusps 20 above the rails 14 is also asymmetric.
  • the gripping mechanism 70 will couple to the taller cusp 20 .
  • the push rod 62 can be advanced to expel the implant 10 from the sheath 60 . Due to the asymmetry of the cusps 20 , one of the struts 12 is positioned for deployment before the other strut 12 . Also due to the asymmetry of the cusps 20 , the shorter cusp 20 is positioned for advancement out of the sheath 60 before the taller cusp 20 is released by the gripping mechanism 70 .
  • FIG. 31B shows, under image guidance, the folded and collapsed implant 10 is aligned with coaptation line near one of the commissures (the delivery catheter 58 has been previously introduced trans-septally into the left atrium, as already described).
  • Manipulating the push rod 62 advances the implant 10 from the sheath 60 .
  • the leading strut 12 is freed first (see FIG. 31B ) and placed against the adjacent commissure.
  • the implant 10 can be manipulated to assure that anchoring structures or mechanisms associated with the leading strut are placed into desired contact with adjoining tissue below and/or above the plane of the annulus. Further advancement of push rod 62 causes the implant 10 to unfold toward the opposite commissure.
  • FIG. 31C shows.
  • the implant 10 can be manipulated to assure that anchoring structures or mechanisms associated with the trailing strut 12 are placed into desired contact with adjoining tissue below and/or above the plane of the annulus. Further advancement of the push rod 62 frees the shorter cusp 12 from the sheath 60 , and the implant 10 springs open along this side (see FIG. 31D ). The gripping mechanism 70 can then be activated (see FIG. 31 ), releasing the taller cusp 12 . The implant 10 springs open in this direction. It can be seen that the. asymmetry of the implant 10 make possible a step-wise deployment of the implant 10 , one component at a time, in the annulus.
  • One or more guide loops 66 or tethers can likewise be employed to assist in the deployment of folded elastic implants of either symmetric or asymmetric types.
  • a metallic, fiber, or polymer guide wire 64 can be looped through the deployment apertures on the struts of a folded symmetric or asymmetric implant 10 prior to the folding and insertion of the implant 10 into the sheath 60 .
  • the legs of the resulting guide wire loop 66 are passed out the proximal end of the sheath 60 for manipulation.
  • both legs of the guide wire loop 66 are advanced distally in tandem through the sheath 60 to advance the loop 66 beyond the deployment apertures and out the distal end of the sheath 60 .
  • the loop 66 is placed within the annulus.
  • the push rod 62 is manipulated to free the folded implant 10 for expansion (see FIG. 33B ).
  • the implant 10 opens while tethered to the guide wire loop 66 .
  • the loop 66 increases in diameter as the struts 12 expand apart.
  • the perimeter of the loop 66 will orient itself along the greatest dimension of the annulus—which is the distance between the commissures.
  • the loop 66 thereby orients the implant 10 with the coaptation line during implant 10 expansion.
  • the legs of the loop 66 guide the struts 12 to the commissures (as FIG. 33C shows).
  • the implant 10 is deployed in the annulus.
  • the guide wire loop 66 maintains control of the strut spacing within the commissures during implant expansion.
  • the gripping mechanism 70 can release the implant 10 .
  • One leg of the wire loop 66 can be pulled to release the implant 10 from the guide wire (see FIG. 33D ).
  • the implant 10 is allowed to fully unfold and seat within the annulus.
  • a second guide wire loop 72 can also be passed through apertures on the cusps 20 .
  • This guide wire loop 72 can be manipulated independently of the first guide wire loop 66 , to control deployment of the expanding implant 10 in the septal-to-lateral dimension. Simultaneous, although independent, control of the expanding implant 10 can be achieved by manipulation of the first guide wire 66 .
  • separate metallic, fiber, or polymer guide wires 92 can be individually threaded (without looping) through small holes on the struts of a folded symmetric or asymmetric implant 10 prior to the folding and insertion of the implant 10 into the sheath 60 (see FIG. 35 ).
  • the separate guide wires 92 are passed out the proximal end of the sheath 60 for manipulation.

  • the guide wires 92 separately guide the respective struts 12 to the commissures (as FIG. 36C shows).
  • the implant 10 is deployed in the annulus.
