Transcatheter valve prosthesis
First Claim
1. 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;
a valve disposed within and attached to the tubular body; and
a trapping member configured to be disposed within the preformed groove on the outer surface of the tubular body, the trapping member configured to form at least a partial loop around the tubular body, wherein(i) the circumferential opening of the preformed groove is in a first state when the outflow end of the tubular body has been deployed from a catheter and the inflow end of the tubular body is disposed within the catheter,(ii) the circumferential opening of the preformed groove is in a second state when both the outflow end and the inflow end are fully deployed from the catheter, the circumferential opening of the second state being relatively smaller that the circumferential opening of the first state, and(iii) a cross-sectional dimension of the trapping member is smaller than the circumferential opening of the first state and larger than the circumferential opening of the second state.

Abstract
A system for implanting a heart valve includes a radially self-expandable tubular body having a preformed groove disposed at an outer surface of the tubular body, and a valve disposed within the tubular body. The preformed groove extends at least partially around the tubular body, and has a circumferential opening facing radially outward. A trapping member is configured to be disposed within the preformed groove on the outer surface of the tubular body and form at least a partial loop around the tubular body. The circumferential opening of the preformed groove is relatively larger when an outflow end of the tubular body has been deployed from a catheter and an inflow end of the tubular body is disposed within the catheter, and the circumferential opening of the preformed groove is relatively smaller when both the outflow end and the inflow end are fully deployed from the catheter.

6. A method for implanting a replacement valve in patient'"'"'s heart, comprising:
-
advancing an elongate outer member from a first delivery catheter to form a loop around native valve leaflets and/or chords with the elongate outer member; partially deploying from a second delivery catheter a radially self-expandable tubular body having an inflow end and an outflow end, a valve disposed within a lumen of the tubular body, 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, such that, when the tubular body is partially deployed, the outflow end but not the inflow end is deployed from the second delivery catheter and the circumferential opening of the preformed groove is relatively larger than when both the outflow end and the inflow end are fully deployed from the second delivery catheter; moving the loop and native valve leaflet tissue and/or chords into the preformed groove through the opening; moving a trapping member into the preformed groove while the tubular body is partially deployed, the trapping member having a cross-sectional shape smaller than the opening of the groove when the outflow end but not the inflow end is deployed from the second delivery catheter; and deploying a remainder of the tubular body from the second delivery catheter after moving the trapping member into the preformed groove, and allowing the opening of the groove to become smaller than the cross-sectional shape of the trapping member. - View Dependent Claims (7, 8, 9, 10)

advancing an elongate outer member from a first delivery catheter to form a loop around native valve leaflets and/or chords with the elongate outer member; deploying from a second delivery catheter a radially self-expandable tubular body having an inflow end and an outflow end, a valve disposed within a lumen of the tubular body, 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, such that, when the tubular body is partially deployed from the second delivery catheter, the outflow end but not the inflow end is deployed from the second delivery catheter and the circumferential opening of the preformed groove is relatively larger than when both the outflow end and the inflow end are fully deployed from the second delivery catheter; moving the loop and native valve leaflet tissue and/or chords into the preformed groove through the opening; and moving a trapping member into the preformed groove after the tubular body is fully deployed from the second delivery catheter, the trapping member having a cross-sectional shape smaller than the opening of the groove when the outflow end but not the inflow end is deployed from the second delivery catheter. - View Dependent Claims (12, 13, 14, 15, 16, 17)
