Low-Profile Prosthetic Valve Structure

摘要

A prosthetic valve assembly that includes a stent, a tissue sleeve and an anchoring mechanism. By loading the three components of the valve assembly into a delivery catheter in a series formation, such that no two components are located within each other, the size of the delivery catheter can be reduced.

主权项

1. An implantable device comprising:
a support structure having an extended configuration and a folded configuration and including:
a first end;a second end;a preformed fold between said first end and said second end;a first portion between said first end and said preformed fold;a second portion between said second end and said preformed fold; wherein said preformed fold at least assists in inverting said first portion into said second portion when said support structure is released from a delivery device; a prosthetic valve structure hingedly attached to said support structure first end, thereby allowing said support structure first portion to invert into said support structure second portion without inverting said prosthetic valve structure.
