Definitions

  • the present invention relates to devices used to deploy intraocular lenses to an eye of a patient. More particularly, the present invention relates to devices
  • At least one movable conveyor configured to transport, at least partially wrap, and protect an intraocular lens during deployment of such lens.
  • An intraocular lens (sometimes referred to as an IOL in the industry) is an implanted prosthesis that replaces the lens in the human eye.
  • An IOL usually replaces the existing crystalline lens because the existing lens has been clouded by a cataract, or as a form of refractive surgery to change the optical power of the eye.
  • An IOL usually comprises a small plastic lens with plastic side struts, called haptics, to hold the lens in place within the capsular bag inside the eye.
  • IOLs were traditionally made of an inflexible material (PMMA), although this has largely been superseded by the use of flexible materials.
  • PMMA inflexible material
  • Most IOLs fitted today are fixed monofocal lenses matched to distance vision. However, other types are available, such as multifocal IOLs, which provide the patient with multiple-focused vision at far and reading distance, and adaptive IOLs, which provide the patient with limited visual accommodation.
  • Deployment devices are used to implant IOLs at the desired implant site in an eye.
  • IOL implant procedures generally involve at least three stages. In one stage, a suitable lens is loaded into the deployment device. In some instances, the lens may be folded or otherwise compressed at this stage to facilitate deployment. In a second stage, the device is actuated to cause transport of the lens from its loaded position to a position in which the lens can be deployed from the device at the desired implant site.
  • the second stage may involve at least a portion of the desired lens folding and/or compression.
  • the device actuation causes the lens to be deployed at the implant site and implanted.
  • Most conventional devices pose an undue risk of creasing, scratching, or otherwise damaging an IOL during an implant procedure.
  • the present invention relates to improved devices used to deploy intraocular lenses to an eye of a patient.
  • Intraocular lens deployment devices in accordance with the present invention are easy to use and provide a lower risk of potential damage to an intraocular lens during an implant procedure.
  • Intraocular lens deployment devices of the present invention include at least one conveyor and other features that allow a lens to be loaded onto or into the conveyor according to a first deployment stage. Actuation of the conveyor causes the lens to be transported and deployed according to second and third stages of deployment. Loading an intraocular lens onto and/or into the conveyor of a device in accordance with the present invention is easily accomplished, thereby minimizing handling of the intraocular lens and advantageously reducing potential damage to the intraocular lens.
  • features of the device and the conveyor help to cause the conveyor and lens to roll up and compress. The rolling action reduces the risk of creasing the lens that might otherwise occur if the lens were to be folded up with too much direct folding force.
  • the conveyor rolls up the lens in a manner effective to at least partially wrap the rolled up lens in a protective manner. This protective wrapping action reduces the risk that the lens will be scratched by device features as the lens is transported and compressed through the device to achieve deployment.
  • a device for deploying an intraocular lens comprises a body portion having an inner space, a loading port through the body portion providing access to the inner space, a lens deployment portion having a lumen in communication with the loading port and the inner space, and a deployment orifice at a distal end of the deployment portion through which the lens is deployed.
  • a conveyor is at least partially positioned within the inner space of the body portion and is configured so the lens can be positioned on and transported by the conveyor.
  • An actuator may be connected to the conveyor, which may be moveable to drive the conveyor relative to the body portion.
  • a device in another embodiment, comprises a body portion having an inner space, a lens deployment portion having a lumen in communication with the inner space of the body portion, and a deployment orifice at a distal end of the deployment portion through which the lens is deployed.
  • a conveyor is at least partially positioned within the inner space of the body portion and is accessible so the lens can be positioned on and transported by the conveyor.
  • a second body portion surrounds the first body portion.
  • An actuator may be connected to the conveyor, which may be moveable to drive the conveyor relative to the body portion to cause deployment of the lens.
  • a device in another embodiment, comprises a body portion having an inner space, a loading port providing access to the inner space, a lens deployment portion having a lumen in communication with the loading port and the inner space, and a deployment orifice at a distal end of the deployment portion.
  • a conveyor is at least partially positioned within the inner space of the body, the conveyor having a first end and a second end.
  • the device includes an actuator moveable relative to the body portion, the first end of the conveyor and the second end of the conveyor connected to the actuator to form a continuous loop.
  • the second end of the conveyor may have plural legs.
  • a device comprises at least one movable conveyor that conveys an intraocular lens from an initial position to a deployment orifice.
  • the device has a shaping zone between the initial position and the deployment orifice, the shaping zone comprising a tapering lumen that causes the conveyor to at least partially wrap around the intraocular lens when the intraocular lens is on the conveyor.
  • the device also has a deployment zone comprising a lumen configured to transport the wrapped intraocular lens to the deployment orifice.
  • This invention also includes conveyors for deploying an intraocular lens with an intraocular lens deployment device.
  • a conveyor has a first end that can be attached to an actuator of the deployment device, a closed tubular body portion configured to wrap the intraocular lens during movement of the tubular body portion and intraocular lens through a tapering portion of the deployment device, an loading region adjacent the closed tubular portion, and a second end that can optionally be attached to the actuator of the deployment device.
  • the conveyor has a first end that can be attached to an actuator of the deployment device, a closed tubular body portion configured to wrap the intraocular lens during movement of the tubular body portion and intraocular lens through a portion of the deployment device, an loading region adjacent the closed tubular portion, and a second end that can be attached to the actuator of the deployment device.
  • the second end can have plural legs, which may define the loading region.

  • End 17 of cannula 30 may have any desired geometry. As illustrated in Figure 4, end 17 of cannula 30 may be square (i.e., perpendicular) to the axis of cannula 30. In an alternative embodiment, distal end 17 may comprise a geometry that may facilitate easier entry into an incision through which an intraocular lens is to be deployed. For example, as shown in Figure 4a, end 17 of cannula 30 may comprise bevel 21.

  • base 24 includes openings 54 and 58
  • openings 54, 58 optionally may be used as separation guides for legs 78 and 80 (see Figure 1 la) of conveyor 74.
  • Each of legs 78, 80 can be fed through a corresponding one of openings 54, 58, respectively, in order to hold the legs 78, 80 apart as the conveyor 74 is actuated. This helps to prevent the conveyor from collapsing onto itself. If the legs 78, 80 are not held apart, conveyor 74 may tend to collapse in some instances, making it more difficult to load. Additional description of conveyor 74 and its loading is provided below.
  • actuator 16 of device 10 comprises handles 38 extending outward from boss 40, which comprises inside surface 42 that defines opening 45. Opening 45 is preferably sized and shaped to provide free sliding engagement between actuator 16 and tubular portion 26 of inner body 14 along the length of tubular portion 26. Opening 45 has channels 44 and 46 sized and shaped to fit with and slidingly engage with guide ribs 34 and 36 of tubular portion 26 of inner body 14. Channels 44, 46 together with guide ribs 34, 36 also function to provide a consistent orientation of actuator 16 relative to inner body 14 as actuator 16 is moved longitudinally along tubular portion 26 during use.
  • Conveyor 74 comprises tubular body portion 76, legs 78 and 80, first end 82, loading region 81, and ends 83 and 84 of legs 78 and 80, respectively.
  • body portion 76 comprises a circular cross-section but other cross-sections such as an oval cross-section or the like can be used.

  • conveyor 74 is derived from a material preferably having a thickness less than about 1 mil (0.001 inch or 0.0254 mm).
  • Preferred exemplary materials include, low density polyethylene (LDPE), high density polyethylene (HDPE), a fluoropolymer such as polytetrafluoroethylene (PTFE) sold under the trade designation TEFLON, combinations of these, and the like.
  • Figures lib and 11c schematically illustrate one method for forming conveyor 74 from a tube-shaped precursor 102.
  • tube-shaped precursor 102 is slit from a starting point 104 to the end 83/84 of precursor 102 to define edges 105.
  • Precursor 102 would be slit a second time as shown by broken line 108 starting from starting point 106 and extending to end 83/84 to define edges 110 and thereby arrive at the exemplary configuration of conveyor 74 shown in Figure 11a.
  • Figure 11c shows how starting points 104 and 106 are longitudinally offset by a distance "d" (desirably from about 1 to 4 times the diameter of the lens to be implanted) so that the region of conveyor 74 between slit starting points 104 and 106 helps to define loading region 81.
  • Loading region 81 is preferably positioned within tubular portion 26 of inner body 14 proximal to loading port 32. From one perspective, loading region 81 forms a protective basket to receive, wrap, and hold the intraocular lens that is to be deployed.
  • actuator 16 is fit over inner body 14. Opening 45 and channels 44, 46 of actuator 16 are preferably sized so that actuator 16 slideably engages tubular portion 26 of inner body 14 for smooth sliding motion back and forth along tubular portion 26. Note how channels 44, 46 fit over ribs 34, 36 so that ribs 34, 36 can help guide actuator 16 and hold actuator 16 in a desired orientation around tubular portion 26.
  • Outer body 12 is fit over inner body 14 in a manner so that ends 23, 25 of arms 20, 22 are mounted to base 24 via mounting holes 11, 13.
  • Tapering portion 18 of outer body 12 fits over tapering portion 28 of inner body 14 with a close fit but still is spaced apart from tapering portion 28 in a manner effective to define an annular gap 52 (see Figures 1 and 2) between tapering portion 28 and tapering portion 18.
  • Gap 52 provides a pathway for installation of and translation of conveyor 74 as described further below. Note how handles 38 of actuator 16 extend past outer body 12 between arms 20, 22; this allows actuator 16 to move along tubular portion 26 without undue interference from arms 20, 22.
  • conveyor 74 is fed through lumen 62 of inner body 14 and is positioned so that an intraocular lens can be loaded onto loading region 81 of conveyor 74 via loading port 32.
  • Legs 78, 80 of conveyor 74 are fed through and extend from openings 70 and 72 (best seen in Figure 9) of inner body 14 near base 24.
  • Tubular portion 76 of conveyor 74 is fed through to extend from deployment orifice 35, and is preferably rolled back over cannula 30 thereby reversing the direction of conveyor 74 and causing tubular portion 76 of conveyor 74 to turn inside out (i.e., invert).
  • First end 82 of conveyor 74 is preferably fed over tapering portion 28 of inner body 14 through gap 52 and extended to and attached to a portion of actuator 1 , such as boss 40, using o-ring 48 in groove 50 (see Figures 9 and 12) or other suitable attachment technique.
  • Tapering portion 18 of outer body 12 surrounds underlying tubular portion 76 of conveyor 74, helping to hold underlying tubular portion 76 of conveyor 74 in a reasonably close fit around inner body 14.
  • legs 78, 80 of conveyor 74 extend from openings 70, 72 of tubular portion 26 and preferably extend back to actuator 16 and attach to boss 40 via o- ring 48. It is understood that these steps for installing conveyor 74 in device 10 may be done in alternate sequences.
  • conveyor 74 from one perspective forms a continuous loop in which legs 78, 80 of conveyor 74 are linked to actuator 16 as is first end 82 to provide a continuous loop.
  • the loop is suitably tensioned with minimal slack so that a lens loaded onto conveyor 74 can be deployed with smooth action.
  • Figure 12 illustrates the arrangement of legs 78, 80 and first end 82 linked to actuator 16 to forming a loop.
  • Figure 14 illustrates an alternate arrangement, where legs 78, 80 are free, extending out lumen 62 proximate base 24.
  • Figure 15 illustrates another alternate arrangement, where conveyor 74 does not have two individual and separate legs, but has a sealed end opposite first end 82.
  • an intraocular lens can be positioned within loading region 81 of conveyor 74 at any desired time.
  • the intraocular lens can be pre-loaded in conveyor 74 before conveyor 74 is loaded in device 10.
  • the intraocular lens can be loaded after conveyor 74 is loaded in device 10, for example, at the time of use.
  • the intraocular lens desirably is positioned within loading region 81 of conveyor 74 with the convex side of the lens positioned down (convex side in contact with conveyor 74).
  • Loading port 32 provides a convenient access for placement of the intraocular lens and allows device 10 to be configured for single use or multiple uses. See Figures 12, 14 and 15 for intraocular lens 19 positioned in loading region 81 via loading port 32.
  • Actuator 16 desirably is pre-positioned at a location so that the stroke length of actuation is sufficient to cause deployment of intraocular lens 19 through orifice 35 and to the desired implant site.
  • a desired starting location involves positioning actuator 16 near tapering portion 28 to provide a maximum stroke length down tubular portion 26 during actuation.
  • Conveyor 74 is sized so that this desirable initial position of actuator 16 allows loading zone 81 to be accessible via loading port 32.
  • actuator 16 is pulled proximally towards base 24, thus causing the portion of conveyor 74 inside lumen 62 to be pulled distally, forward toward deployment orifice 35.
  • This conveys intraocular lens 19 from loading zone 27 through staging zone 29 and shaping zone 31 toward deployment orifice 35; see Figure 5.
  • tapering portion 28 of inner body 14 causes conveyor 74 and intraocular lens 19 to roll up and compress before reaching deployment cannula 30 of deployment zone 33.
  • This shaping action also causes conveyor 74 to wrap and protect intraocular lens 19.
  • Intraocular lens 19 generally only comes into contact with conveyor 74.
  • Conveyor 74 generally is substantially stationary and does not unduly move, if at all, relative to intraocular lens 19 except for the rolling and compressing action. Instead, relative movement mainly occurs between conveyor 74 and inner body 14 so that the friction of sliding contact is taken by the interface between conveyor 74 and inner body 14.

Abstract

La présente invention concerne des dispositifs de mise en place de lentilles intraoculaires dans un œil d'un patient. Les dispositifs de mise en place de lentilles intraoculaires comprennent au moins un transporteur et d'autres caractéristiques qui permettent le chargement d'une lentille sur ou dans le transporteur à une première étape de la mise en place. L'actionnement du transporteur entraîne le transport de la lentille et sa mise en place selon des deuxième et troisième étapes de mise en place. Le chargement d'une lentille intraoculaire sur et/ou dans le transporteur est facile, minimisant ainsi la manipulation de la lentille intraoculaire et réduisant avantageusement les éventuels dommages à la lentille intraoculaire. Durant l'actionnement, les caractéristiques du dispositif et du transporteur aident à déclencher l'enroulement et la compression du transporteur et de la lentille, ce qui réduit le risque de rayure de la lentille étant donné qu'elle est transportée et compressée à travers le dispositif jusqu'à sa mise en place.
