First Claim
1. An apparatus comprising:
- an implant structure, which comprises a contracting mechanism, which comprises (a) a rotatable structure, arranged such that rotation of the rotatable structure contracts the implant structure, and (b) a locking mechanism;
a rotation tool, which is configured to engage the rotatable structure, and to rotate the rotatable structure in response to a rotational force applied to the rotation tool; and
a longitudinal guide member, which is (a) removably coupled to the contracting mechanism, (b) configured to guide the rotation tool to the rotatable structure, and (c) comprises a distal force applicator,wherein the rotation tool and the longitudinal guide member are arranged such that the rotation tool is axially moveable with respect to the longitudinal guide member, andwherein the contracting mechanism is arranged such that;
the locking mechanism is unlocked when the longitudinal guide member is coupled to the contracting mechanism in a first state, thereby allowing the rotatable structure to rotate,the locking mechanism is locked when the longitudinal guide member is coupled to the contracting mechanism in a second state, thereby restricting the rotation of the rotatable structure, andthe locking mechanism is locked when the longitudinal guide member is not coupled to the contracting mechanism, thereby restricting the rotation of the rotatable structure.

Abstract
An implant structure includes a contracting mechanism, including a rotatable structure for contracting the implant structure, and a locking mechanism. A rotation tool is configured to engage and rotate the rotatable structure. A longitudinal guide member is removably coupled to the contracting mechanism, configured to guide the rotation tool to the rotatable structure, and includes a distal force applicator. The rotation tool is axially moveable with respect to the guide member. The contracting mechanism is arranged such that the locking mechanism is (a) unlocked when the guide member is coupled to the contracting mechanism in a first state, thereby allowing the rotatable structure to rotate, and (b) locked when (i) the guide member is coupled to the contracting mechanism in a second state, thereby restricting the rotation of the rotatable structure, and (ii) the guide member is not coupled to the contracting mechanism, thereby restricting the rotation of the rotatable structure.

18. An apparatus comprising:
-
an implant structure, which comprises (a) a flexible elongated contracting member and (b) a contracting mechanism, which (i) is configured to contract the implant structure by pulling on the contracting member, and (ii) comprises a locking mechanism; a rotation tool, which is configured to engage the contracting mechanism, and to actuate the contracting mechanism to pull on the contracting member; and a longitudinal guide member, which (a) is separate and distinct from the flexible elongated contracting member (b) is removably coupled to the contracting mechanism, (c) is configured to guide the rotation tool to the contracting mechanism, and (d) comprises a distal force applicator, wherein the rotation tool and the longitudinal guide member are arranged such that the rotation tool is axially moveable with respect to the longitudinal guide member, and wherein the contracting mechanism is arranged such that; the locking mechanism is unlocked when the longitudinal guide member is coupled to the contracting mechanism in a first state, thereby allowing actuation of the contracting mechanism, the locking mechanism is locked when the longitudinal guide member is coupled to the contracting mechanism in a second state, thereby locking the contracting mechanism, and the locking mechanism is locked when the longitudinal guide member is not coupled to the contracting mechanism, thereby locking the contracting mechanism. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33)
