Abstract (en)
[origin: WO2007100268A2] Method and devices including novel suture composition, catheter type suture transporters, pushers -and tying instruments, implant-pledget for anchoring onto the mitral leaflet, myocardial free wall entry site occluder, and technique for catheter based treatment of mitral regurgitation are presented. In one embodiment, a leaflet tension apparatus is implanted to adjust the systolic leaflet amplitude excursion. A continuous guiding suture track is created from the direct left ventricular puncture site through one or two puncture sites of the leaflet (1114) via the transseptal catheter and femoral vein; a pledget-implant (84) is apposed onto the exteriorized distal (venous) suture end via its integrated suture part and is anchored onto the atrial leaflet surface (11141) by retracting the guiding suture from the epicardial end. Silicon tube (70) is interposed between the leaflet and the free myocardial wall (1113) covering the implant's integrated sutures (841) which are directed through the free myocardial wall oclluder (90) and secured to its epicardial segment by an adjustable knot (9021x841) so as to keep the leaflet at the wanted distance during systole whilst the valve opening remains unhindered.
