Slotted annuloplasty ring
First Claim
1. An annuloplasty device comprising a shape memory material and configured to support a heart valve, said annuloplasty device comprising:
- a tubular body having a circumference;
said body further comprising a slot extending along at least a portion of the body'"'"'s circumference;
an insert member within said body, said insert member extending at least partially along the circumference of the body;
wherein said annuloplasty device has a first shape in a first configuration and a second shape in a second configuration;
wherein said annuloplasty device is configured to transform from said first configuration to said second configuration in response to an activation energy applied thereto.

Abstract
Methods and devices are provided for support of a body structure. The devices can be adjusted within the body of a patient in a minimally invasive or non-invasive manner, such as by applying energy percutaneously or external to the patient'"'"'s body. The energy may include, for example, acoustic energy, radio frequency energy, light energy and magnetic energy. Thus, as the body structure changes size and/or shape, the size and/or shape of the annuloplasty rings can be adjusted to provide continued reinforcement. In certain embodiments, the devices comprise a shape memory material, and further include a body member and an insert member. The body member has a circumference and a slot that extends at least partially along the circumference of the body. The insert member extends at least partially along the circumference of the body. The device has a first shape in a first configuration and a second shape in a second configuration, and is configured to transform from a first configuration to a second configuration in response to a first activation energy applied thereto.

23. A method of assembling an annuloplasty device comprising a shape memory material, comprising:
-
providing an elongate insert member;
providing a tubular body having a circumference;
said body further comprising a slot extending along at least a portion of the body'"'"'s circumference;
deforming one of the tubular body and the insert member into a memorized shape having a curvature;
positioning the insert member at least partially within the tubular body, resulting in the other of the tubular body and the insert member substantially conforming to the curvature;
wherein said annuloplasty device is configured to transform from a first configuration to a second configuration in response to an activation energy applied thereto. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38)
