Kit for implanting in a duct
First Claim
1. A kit for implanting in a duct, the kit comprising:
- a tubular endoprosthesis; and
a prosthetic valve configured to be implanted in, and withdrawn from said tubular endoprosthesis;
wherein said prosthetic valve comprises;
a resilient carrier frame that is radially deformable in an elastic manner relative to a central axis of said tubular endoprosthesis between a deployed position in which said resilient carrier frame rests against said tubular endoprosthesis, and a folded position, said resilient carrier frame being biased towards the deployed position by its resiliency;
a flexible shutter connected to said resilient carrier frame, said flexible shutter being deformable between an obstruction position in which said flexible shutter is extended transverse to the central axis of said tubular endoprosthesis and a release position in which said flexible shutter is contracted transverse to the central axis of said tubular endoprosthesis to allow a fluid to flow through said resilient carrier frame; and
integrated centripetal compression means for compressing said resilient carrier frame from the deployed position towards the folded position,wherein said integrated centripetal compression means comprises a clamp having at least two branches connected together at a common region located along a central axis of said resilient carrier frame in the deployed position, each branch having a connection segment connected to said flexible shutter and a drive segment for centripetally compressing said resilient carrier frame towards the folded position, andwherein the common region is located at a distance from said connection segments of said branches, said drive segments are located between said connection segments and the common region, axially apart from said connection segments, and said drive segments are spaced axially away from said flexible shutter.

Abstract
A kit for implanting in a duct, which includes a tubular endoprosthesis and a prosthetic valve is disclosed. The prosthetic valve includes a carrier frame that is radially deformable in elastic manner relative to a central axis of the tubular endoprosthesis between a deployed, implanted position, and a folded, implanting position. The carrier frame is urged elastically towards its deployed position. A flexible shutter is connected to the carrier frame. The shutter is deformable between an obstruction position in which it is extended transversely, and a release position in which it is contracted transversely under to allow a fluid to flow through the carrier frame. The carrier frame also includes an integrated centripetal compressing mechanism for centripetally compressing the carrier frame towards folded position.
