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.
Claims8
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.
3 more elements
A transcatheter valve comprising:
- a multi-part frame, including:
- a body frame having a generally tubular shape defining a body frame lumen,
- a leaflet frame having a generally annular shape defining a plurality of bases and a plurality of posts, the body frame extending coaxially, adjacent to and spaced apart from the leaflet frame;
- and
- a plurality of leaflets coupled to the plurality of bases between the plurality of posts,
- wherein the multi-part frame is configured to be everted into itself from an axially extended, non-everted configuration in which the leaflet frame is spaced axially apart from the body frame to an everted configuration in which the leaflet frame is received at least partially within the lumen of the body frame.
