1. A method comprising performing each of the following steps during a transcatheter procedure:
- placing, into a body of a subject, an implant structure, which includes (a) exactly one continuous flexible sleeve, and (b) a contracting mechanism that is directly coupled to a flexible longitudinal member and includes a rotatable structure, such that the flexible longitudinal member extends outside of the body;
anchoring the implant structure to a tissue;
thereafter, guiding a tool along, over, and around the flexible longitudinal member to the rotatable structure by moving the tool;
thereafter, contacting and engaging the rotatable structure with the tool; and
thereafter, contracting the implant structure by rotating the rotatable structure using the tool, so as to contract the tissue.

Abstract
Apparatus is provided that includes an implant structure, which includes a contracting mechanism, which includes a rotatable structure, arranged such that rotation of the rotatable structure contracts the implant structure. A longitudinal member is coupled to the contracting mechanism. A tool for rotating the rotatable structure is configured to be guided along the longitudinal member, to engage the rotatable structure, and to rotate the rotatable structure in response to a rotational force applied to the tool. Other embodiments are also described.

18. A method comprising performing each of the following steps during a transcatheter procedure:
-
placing, into a body of a subject, an implant structure, which includes a contracting mechanism that (a) is coupled to a flexible longitudinal member and (b) includes a rotatable structure, such that the flexible longitudinal member extends outside of the body, wherein the flexible longitudinal member includes an element selected from the group consisting of;
at least one wire, and a suture, wherein a proximal end of the flexible longitudinal member passes at least partially through a rotation handle, which includes a first-tube rotation knob coupled to a first tube of a tool, a second-tube rotation knob coupled to a second tube of the tool, and a control knob, which (a) when in a first position, engages both the first-tube rotation knob and the second-tube rotation knob, and (b) when in a second position, engages the second-tube rotation knob but not the first-tube rotation knob, and engages a housing of the rotation handle, thereby rotationally fixing the control knob to the housing of the rotation handle;
anchoring the implant structure to a tissue;thereafter, guiding the tool over the flexible longitudinal member to the rotatable structure by moving the tool, by passing the first tube over the flexible longitudinal member, wherein the first tube is positioned in the second tube; thereafter, contacting and engaging the rotatable structure with the tool, by engaging the rotatable structure with the second tube; thereafter, contracting the implant structure by rotating the rotatable structure using the tool, by rotating the first and second tubes by rotating the control knob when in the first position, so as to contact the tissue; and after rotating the rotatable structure, decoupling the flexible longitudinal member from the contracting mechanism by moving the control knob into the second position, and subsequently rotating the first tube by rotating the first-tube rotation knob.

19. A method comprising performing each of the following steps during a transcatheter procedure:
-
placing, into a body of a subject, an implant structure, which includes (a) exactly one continuous flexible sleeve, and (b) a contracting mechanism directly coupled to a flexible longitudinal member, such that the flexible longitudinal member extends outside of the body;
anchoring the implant structure to a tissue;thereafter, guiding a tool along, over, and around the flexible longitudinal member to the contracting mechanism by moving the tool; thereafter, contacting and engaging the contracting mechanism with the tool; and thereafter, using the tool, contracting the implant structure by actuating the contracting mechanism to pull on a flexible contracting member of the implant structure, which flexible contracting member is coupled to the contracting mechanism, so as to contact the tissue. - View Dependent Claims (20, 21, 22, 23)
