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 unfolded configuration and a folded configuration and including:
a first end;a second end; and,a lumen extending between said first end and said second end; wherein said support structure is biased toward a folded configuration in which said first end is inverted into said lumen; wherein said support structure tends to assume said folded configuration when said support structure is released from a delivery device; a prosthetic valve structure hingedly attached to said support structure first end such that said prosthetic valve structure is not inverted when said support structure inverts.
