Delivery tool for implantation of spool assembly coupled to a helical anchor
First Claim
1. Apparatus, comprising:
- a tissue-adjusting member configured to be coupled to tissue of a patient, the tissue-adjusting member comprising a tissue-adjusting member selected from the group consisting of;
one or more artificial chordae tendineae and at least a portion of an annuloplasty ring structure, the tissue-adjusting member comprising;
a rotatable structure that is configured to adjust a tension of the tissue-adjusting member, in a manner in which during rotation of the rotatable structure in a first rotational direction in order to apply tension to the tissue-adjusting member, successive portions of the tissue-adjusting member advance with respect to and contact the rotatable structure;
a locking mechanism coupled to the rotatable structure, the locking mechanism being configured to restrict rotation of the rotatable structure; and
a tissue anchor coupled to the tissue-adjusting member and configured to screw into the tissue of the patient; and
a delivery tool reversibly coupleable to the rotatable structure, the delivery tool comprising;
at least a first actuating element configured to rotate the rotatable structure while not facilitating rotation of the tissue anchor; and
an elongate locking mechanism release which slides through a lumen of the tool in order to facilitate (1) locking of the rotatable structure to restrict rotation of the rotatable structure, and (2) maintaining the rotatable structure in an unlocked state in order to facilitate rotation of the rotatable structure by the first actuating element and thereby facilitate the applying of tension to the tissue-adjusting member.

Abstract
Apparatus is provided, including a tissue-adjusting member configured to be coupled to tissue of a patient, a rotatable structure that is configured to adjust a tension of the tissue-adjusting member, a tissue anchor coupled to the tissue-adjusting member and configured to screw into the tissue of the patient, and a delivery tool reversibly coupleable to the rotatable structure. The delivery tool comprises a first actuating element configured to rotate the tissue anchor so as to facilitate screwing of the tissue anchor into the tissue of the patient while not facilitating rotation of the rotatable structure, and a second actuating element configured to rotate the rotatable structure while not facilitating rotation of the tissue anchor. Other applications are also described.

32. A method, comprising:
-
providing apparatus including; a tissue-adjusting member configured to be coupled to tissue of a patient, the tissue-adjusting member including a tissue-adjusting member selected from the group consisting of;
one or more artificial chordae tendineae and at least a portion of an annuloplasty ring structure, the tissue-adjusting member including;a rotatable structure that is configured to adjust a tension of the tissue-adjusting member, in a manner in which during rotation of the rotatable structure in a first rotational direction in order to apply tension to the tissue-adjusting member, successive portions of the tissue-adjusting member advance with respect to and contact the rotatable structure; a locking mechanism coupled to the rotatable structure, the locking mechanism being configured to restrict rotation of the rotatable structure; and a tissue anchor coupled to the tissue-adjusting member and configured to screw into the tissue of the patient; and a tool reversibly coupleable to the rotatable structure, the tool including; at least a first actuating element configured to rotate the rotatable structure while not facilitating rotation of the tissue anchor, and an elongate locking mechanism release which slides through a lumen of the tool in order to facilitate (1) locking of the rotatable structure to restrict rotation of the rotatable structure, and (2) maintaining the rotatable structure in an unlocked state in order to facilitate rotation of the rotatable structure by the first actuating element and thereby facilitate the applying of tension to the tissue-adjusting member; using the tool, rotating the rotatable structure by actuating the first actuating element of the tool, while not rotating the tissue anchor. - View Dependent Claims (33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44)
