Closure element for use with an annuloplasty structure
First Claim
1. Apparatus, comprising an implant structure configured to treat a native atrioventricular valve of a patient, the implant structure comprising:
- a sleeve having a lumen and at least one lumen end, the at least one lumen end being shaped so as to define an end opening;
an end flap disposed in a vicinity of the at least one lumen end, the end flap being configured to cover the end opening; and
a contracting mechanism coupled to the implant structure and configured to (a) contract at least a contraction-facilitated portion of the implant structure, and (b) actuate the end flap so as to cover the end opening.

Abstract
Apparatus and methods are described including an implant structure configured to treat a native atrioventricular valve of a patient, the implant structure including a sleeve having a lumen and at least one end, the at least one end being shaped so as to define an opening. A closure element is disposed in a vicinity of the at least one end, the closure element being configured to facilitate closure of the opening. A contracting mechanism is coupled to the implant structure and configured to contract at least a contraction-facilitated portion of the implant structure. Other applications are also described.

16. A method, comprising:
-
positioning an implant structure along an annulus of a native atrioventricular valve of a patient, the implant structure including (a) a sleeve having a lumen and at least one lumen end, the at least one lumen end being shaped so as to define an end opening, (b) an end flap disposed in a vicinity of the at least one lumen end, and (c) a contracting mechanism coupled to the implant structure; fastening at least part of the implant structure to the annulus; covering the end opening with the end flap; and actuating the contracting mechanism to (a) contract at least a contraction-facilitated portion of the implant structure, and (b) actuate the end flap so as to cover the end opening. - View Dependent Claims (17, 18, 19, 20, 21)

22. Apparatus, comprising an implant structure configured to treat a native atrioventricular valve of a patient, the implant structure comprising:
-
a sleeve having a lumen and at least one lumen end, the at least one lumen end being shaped so as to define an end opening; a closure element disposed in a vicinity of the at least one lumen end, the closure element being configured to facilitate closure of the end opening; and a contracting mechanism, which (a) is coupled to the implant structure, (b) comprises a flexible elongated contracting member, (c) is configured to contract at least a contraction-facilitated portion of the implant structure by tightening the contracting member, and (d) comprises a locking mechanism, which (i) is disposed at a location other than in the vicinity of the at least one lumen end, and (ii) when locked, prevents tightening and loosening of the contracting member. - View Dependent Claims (23, 24, 25, 26, 27)

28. A method comprising:
-
positioning an implant structure along an annulus of a native atrioventricular valve of a patient, the implant structure including (a) a sleeve having a lumen and at least one lumen end, the at least one lumen end being shaped so as to define an end opening, (b) a closure element disposed in a vicinity of the at least one lumen end, and (c) a contracting mechanism, which (i) is coupled to the implant structure and (ii) includes a flexible elongated contracting member, and (d) includes a locking mechanism, which (i) is disposed at a location other than in the vicinity of the at least one lumen end, and (ii) when locked, prevents tightening and loosening of the contracting member; fastening at least part of the implant structure to the annulus; closing the end opening by actuating the closure element to close; contracting at least a contraction-facilitated portion of the implant structure by actuating the contracting mechanism to tighten the contracting member; and locking the locking mechanism. - View Dependent Claims (29, 30, 31, 32)
