Abstract
A system for implanting a heart valve that includes a radially self-expandable tubular body having an inflow end and a preformed groove disposed at an outer surface of the tubular body between the inflow end and the outflow end, wherein the preformed groove extends at least partially around the tubular body and having a circumferential opening facing radially outward of the tubular body. A valve may be disposed within and attached to the tubular body. Additionally, a trapping member may be configured to form at least a partial loop encircling the preformed groove so as to trap portions of native valve leaflets and/or chords in the preformed groove, the trapping member including one or more barbs.

A system for implanting a heart valve, comprising:
- a radially self-expandable tubular body having an inflow end and an outflow end and a preformed groove disposed at an outer surface of the tubular body between the inflow end and the outflow end, the preformed groove extending at least partially around the tubular body and having a circumferential opening facing radially outward of the tubular body;
- and
- a trapping member configured to form at least a partial loop encircling the preformed groove so as to trap portions of native valve leaflets and/or chords in the preformed groove, the trapping member including an inner member and an outer tube,
- wherein
- the outer tube includes a plurality of openings, and one or more barbs are disposed on the inner member such that the one or more barbs are radially inward with regard to the inner member, when deployed, so that the one or more barbs are configured to pierce the native valve leaflets and/or chords when the tubular body is implanted in a patient;
- and
- the tubular body is configured to have a valve disposed therein and attached thereto.

- a trapping member configured to form at least a partial loop encircling the preformed groove so as to trap portions of native valve leaflets and/or chords in the preformed groove, the trapping member including an inner member and an outer tube;
- and
- a projection having a first end located at a side surface of the tubular body at a distance from a center of the preformed groove and a second free end, and configured to define the preformed groove between the projection and the tubular body, the preformed groove having an opening between the tubular body and the second free end of the projection;
- wherein
- the outer tube includes a plurality of openings, and one or more barbs are disposed on the inner member such that the one or more barbs are configured to pierce the native valve leaflets and/or chords when the tubular body is implanted in a patient;
- at least one of the barbs is configured to attach to the projection to secure the system to the portions of native valve leaflets and/or chords;
- and
- the tubular body is configured to have a valve disposed therein and attached thereto.

- the one or more barbs comprise a first set of barbs configured to be oriented toward an inflow side of the groove when the trapping member encircles the preformed groove, and a second set of barbs configured to be oriented toward an outflow side of the groove when the trapping member encircles the preformed groove;
- and
- the tubular body is configured to have a valve disposed therein and attached thereto.
