Endoventricular stay and delivery system

摘要

An endoventricular device includes a backbone and a plurality of segments having a plurality of anchors that are delivered to the treatment site in an inverted delivery configuration within a delivery catheter and when deployed moves from the inverted delivery configuration to a tissue penetrating implantation configuration.

主权项

1. An endoventricular stay delivery system comprising:
an elongate delivery catheter having a lumen terminating in an open distal end; an elongate tubular stay adapted to be inverted from a) an implantation configuration having a memorized tubular shape with a first surface facing inwardly to b) a tubular delivery configuration constrained within the lumen of the delivery catheter with the first surface facing outwardly, the tubular stay comprising: a one-piece backbone extending the entire length of the tubular member, the backbone having first and second ends and a plurality of continuous segments defined therebetween, and a plurality of anchors formed integrally with the backbone and, when the tubular member is in the tubular delivery configuration, each anchor extends in a circumferential direction around the tubular member from the backbone to a tissue penetrating end of the anchor.
