A method is provided for repairing the tricuspid valve of a patient using tension. A radially-expandable stent is implanted in a coronary sinus of the patient. A tissue anchor is implanted in tissue in the vicinity of the tricuspid valve. The tricuspid valve is repaired by applying tension between the radially-expandable stent and the tissue anchor using a flexible longitudinal member that connects the radially-expandable stent and the tissue anchor.

Tricuspid valve repair using tension

Apparatus is provided including a radially-expandable percutaneous implant shaped so as to define a tension-distributing element. A flexible longitudinal member is coupled at a first portion thereof to at least a portion of the percutaneous implant via the tension-distributing element. The tension-distributing element is configured to distribute tension applied by the flexible longitudinal member along a longitudinal length of the percutaneous implant.

Method and apparatus for tricuspid valve repair using tension

Apparatus is provided, including a radially-expandable percutaneous implant, a tissue anchor, and a connecting element shaped so as to provide an annular loop surrounding a proximal portion of the tissue anchor in a manner which enables rotation of the anchor about a central longitudinal axis thereof when surrounded by the annular loop. The apparatus also includes a flexible longitudinal member coupled at a first portion thereof to at least a portion of the percutaneous implant and at a second portion to the connecting element. The annular loop of the connecting element facilitates rotation of the tissue anchor about the central longitudinal axis such that the anchor can rotate about the central longitudinal axis with respect to the annular loop, the flexible longitudinal member, and the percutaneous implant. Other applications are also described.

The invention is an instrument for cleaning and/or shaping and/or widening a channel that exists in or through a solid object. The design of the instrument the superelastic and shape memory properties of the material from which it is made, allow the inner volume enclosed by the instrument, its outer contour, or both to change as a result of the forces exerted upon it while working, thereby shaping the instrument to the three-dimensional contour of the channel. A preferred embodiment of the instrument is an endodontic file for use in the cleaning, shaping, and widening stages of a root canal procedure.
