Abstract
Described embodiments are directed toward centrally-opening, leaflet valve devices and systems for transcatheter delivery having a two-piece valve body as well as methods of making and delivering the two-piece valve devices. A transcatheter valve includes a collapsed configuration and an expanded configuration. The transcatheter valve can further include an everted configuration and a non-everted configuration.
Claims20
A transcatheter valve comprising:
- a multi-part frame defining a flow lumen through which fluid is able to selectively flow, the multi-part frame including,
- an outer support portion having a generally tubular shape defining a first lumen,
- an evertible support portion having a generally tubular shape, and
- a flexible bridge material coupling the evertible support portion to the outer support portion, such that the evertible support portion is transitionable from a first, laterally adjacent position relative to the outer support portion and a second, everted position in which the evertible support portion is at least partially located within the first lumen of the outer support portion;
- and
- a plurality of leaflets coupled to the multi-part frame, each leaflet being moveable between an open position and closed position to selectively block and unblock the flow lumen of the multi-part frame.

A transcatheter valve delivery system comprising:
- a delivery catheter;
- and
- a transcatheter valve comprising:
- a multi-part frame defining a flow lumen through which fluid is able to selectively flow, the multi-part frame including,
- an outer support portion having a generally tubular shape defining a first lumen,
- an evertible support portion having a generally tubular shape, and
- a flexible bridge material coupling the evertible support portion to the outer support portion, such that the evertible support portion is transitionable from a first, laterally adjacent position relative to the outer support portion and a second, everted position in which the evertible support portion is at least partially located within the first lumen of the outer support portion;
- and
- a plurality of leaflets coupled to the multi-part frame, each leaflet being moveable between an open position and closed position to selectively block and unblock the flow lumen of the multi-part frame when the transcatheter valve is in an expanded configuration;
- wherein the outer support portion and the evertible support portion are mounted on the delivery catheter in a collapsed configuration with the evertible support portion in the first laterally adjacent position relative to the outer support portion;
- wherein the delivery catheter is operable to advance the transcatheter valve to an implantation site.
