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 include a shape memory material that is responsive to changes in temperature and/or exposure to a magnetic field. A material having enhanced absorption characteristics with regard to a desired heating energy may be used in order to facilitate heating and adjustment of the support device.

In certain embodiments, the devices include a body member including a shape memory material. The shape memory material is configured to transform from a first shape to a second shape in response to being heated. The devices also include a thermally insulative material at least partially covering the body member and a thermally conductive material extending into the thermally insulative material. The thermally conductive material is configured to communicate thermal energy to the body member.

Abstract: The present invention includes a body implantable lead having a multipolar proximal connector, at least a first conductor coupled to at least one stimulating electrode, a sensor for sensing at least one physiologic parameter of the body, and a second and a third conductor coupled to the sensor. The sensor is hermetically sealed in a D-shaped housing. Sensor components are mounted onto a microelectronic substrate which is advantageously placed on an inner flat portion of the D-shaped housing. End caps having sealing rings, either glass frit or metal, are used to seal the ends of the shell. A hermetic seal is easily achieved by heating the sealing material until they re-flow between the end caps and the shell. Advantageously, the sensor terminals are sized to fit snugly within a narrow bore of the end cap which is then circumferentially welded closed. The D-shaped sensor is placed on a carrier having at least two lumens. At least the first and second conductors pass through the lumens for connection with the stimulating electrode and the distal end of the sensor. Advantageously, the D-shaped housing reduces the area that needs to be hermetically sealed by more than half, and thus reduces the overall diameter of the lead. Advantageously, the conductors coupled to the sensor function independently from the stimulation conductors so that interference with basic operation of the pacemaker is prevented.
