Systems and methods treat a heart valve using a magnetically adjustable annuloplasty ring attached to or near a cardiac valve annulus. A changing magnetic field may be used to selectively increase or decrease a circumference of, or otherwise modify the shape of, the implanted annuloplasty ring. The adjustable annuloplasty ring includes a tubular body member, one or more adjustable members, and an internal magnet within the tubular body member. The tubular body member and the one or more adjustable members form a ring shape. The internal magnet is configured to rotate in response to a rotating external magnetic field. The internal magnet is coupled to the one or more adjustable members to change a dimension of the ring shape as the internal magnet rotates. A system for treating a heart valve may include an external adjustment device having one or more external magnets to generate the rotating external magnetic field.

Adjustable implant system

Described herein is a hose, wherein the hose has a length having a distal end and a proximal end, and an inner diameter and an outer diameter. The hose is comprised of a first layer; and a second layer, wherein the first layer and the second layer extend along at least a portion of the length and wherein a longitudinal compressive force applied to either the distal end or the proximal end of the hose causes the first layer to lock against the second layer.
