Zusammenfassung: | 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. |
