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 single 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;
at least one connector hingedly connecting the prosthetic valve structure to the support structure first end such that the at least one connector rotates relative to said support structure first end to allow said support structure first portion to invert into said support structure second portion without inverting said prosthetic valve structure.

Abstract
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.

8. An implantable device comprising:
-
a support structure having a single performed fold, and a first portion and a second portion separated from said first portion by said preformed fold; a valve assembly; a connector connecting said valve assembly to said first portion of said support structure; wherein said implantable device has a first configuration and a second configuration; wherein in said first configuration, said support structure is unfolded and said support structure, said valve assembly, and said connector are axially arranged; wherein in said second configuration, said connector rotates relative to said first portion of said support structure while said first portion is inverted into said second portion and said valve assembly is drawn at least partially into said first portion by said connector. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16)

17. A method of delivering an implantable device comprising:
-
arranging a first component with a single preformed circumferential fold, a connector, and a second component axially in a delivery catheter, said connector connecting said first component and said second component such that said first and second components do not overlap; releasing said first component, said connector, and said second component at a target site from said catheter; allowing said first component to fold into itself along said circumferential fold while said connector pivots, thereby drawing said second component axially toward said first component. - View Dependent Claims (18, 19, 20)
