Definitions

  • the invention concerns a cardiac catheter for the retrograde catheterization of the left atrium of the heart.
  • Catheterization of the left atrium presents great interest and it is performed for diagnostic, research (function of the left atrium, hemodynamic studies, secretory capacity) and therapeutic (balloon mitral valvuloplasty) purposes.
  • catheterization of the left atrium became a nessecity with the establishment of percutaneous mitral valvuloplasty as an important therapeutic modality for the nonsurgical treatment of rheumatic mitral stenosis.
  • Retrograde (via the left ventricle) catheterization of the left atrium presents certain difficulties, and has the risk of damage to the subvalvular apparatus. These result from the position of the mitral ring relative to the left atrial cavity. To approach the mitral orifice, the catheter must bend through a large angle.
  • the present invention is a safe and effectives means for the successful retrograde catherization of the left atrium that bypassess the serious disadvantages of the transseptal catheterization.
  • the present invention has the advantage that manipulation of a steering arm enables the configuration of the catheter tip to be changed by remote control, so that the tip may assume different forms.
  • a forwardly movement of the steering arm along the longitudinal axis of the shaft increases the angle of the curve of the distal part of the shaft and the reawardly movement of the steering arm along the longitudinal axis of the shaft reduces the angle of the distal part of the shaft.
  • the present invention provides a safe and effective means for the retrograde catheterization of the left atrium for diagnostic, research and therapeutic purposes.
  • FIGURE 1 shows the distal of a catheter embodying the present invention in a straightened configuration
  • FIGURE 2 shows the distal part of the same catheter as in FIGURE 1, but in an intermediately curved configuration
  • FIGURE 3 shows the distal part of a catheter of this invention in its completely curved configuration
  • FIGURE 4 shows the proximal part of a catheter provided with a steering system that enables the configuration of the distal part of the catheter to be altered by remote control thereof as shown in FIGURES 1-3, as above Descrition Of The Prefered Embodiment
  • the drawings illustrate the steerable catheter for the catheterization of the left atrium, which consists of a cardiac catheter (1,3,5) that has in its proximal part (7) a steering arm or wire (8) which passes through the lumen of the catheter shaft and emerges a short distance from the distal end of catheter shaft.
  • the distal end region of the the arm or wire is attached to the distal end of the catheter as shown in
  • FIGURE 1 When the steering arm or wire (8) is advanced, by external manipulations, the angle of the curve of the distal part of the shaft is increased, until the distal part of the catheter acquires, at the forewardmost advancement of the steering arm or wire (2), a straigtened configuration (1) which facilitates insertion of the catheter to the femoral artery and advancement to the left ventricle.
  • the steering arm or wire (8) is retracted (4), again by external manipulations, the angle of the curve of the distal part of the catheter is closed (3), up to the completely curved configuration (5) at the rearwardmost retraction of the steering arm or wire

Abstract

Cathéter cardiaque dirigeable pour le cathétérisme rétrograde (se faisant par le ventricule gauche) de l'oreillette gauche. Ledit cathéter se compose d'un cathéter proprement dit (1, 5) pourvu, dans sa partie proximale, d'un bras de direction (8) qui passe par la lumière de la tige de cathéter, dépasse légèrement de l'extrémité distale de la tige de cathéter, et est fixé à l'extrémité distale du cathéter (1, 2, 5, 6). Lorsque le bras de direction (8) est sorti (2), par des manipulations externes, l'angle de courbure de la partie distale de la tige augmente (1), et lorsque le bras de direction (8) est rentré (6), l'angle de courbure de la partie distale du cathéter se referme (5). Ces manipulations, combinées avec la rotation adéquate de la tige de cathéter autour de son axe longitudinal, rotation également obtenue par des manipulations externes, permettent de faire accéder le cathéter à l'oreillette gauche, lorsque le cathéter a été introduit, par un déplacement rétrograde, dans le ventricule gauche.
