Abstract:
1. Apparatus, comprising: a rotatable structure having a first end shaped to define a first opening, and a second end shaped to define a second opening, the rotatable structure being shaped to define a channel extending from the first opening to the second opening, the channel being configured for passage therethrough of an elongate tool, and the second end of the rotatable structure having a lower surface thereof shaped to define one or more recesses; a mechanical element having a surface coupled to the lower surface of the rotatable structure, the mechanical element being shaped to provide: a flexible, longitudinal member having first and second end portions thereof, at least the first end portion of the longitudinal member being coupled to the rotatable structure in a manner in which, as a result of rotation of the rotatable structure: wherein: the longitudinal member comprises an implant comprising an artificial chorda tendinea, and the apparatus is for adjusting at least one dimension of the implant, the rotatable structure is implantable at a first portion of tissue facing a ventricular lumen of a ventricle of a patient, the second end portion of the longitudinal member is couplable to at least one leaflet of an atrioventricular valve of the patient, and the rotatable structure is rotatable to advance the first end portion of the longitudinal member with respect to the rotatable structure, in a manner which alters a distance between the second end portion of the longitudinal member and the rotatable structure.
