摘要： A prosthetic implant for treating a diseased aortic valve is described. The prosthetic implant includes a substantially tubular body configured to be positioned in an aorta of a patient, at or near the patient's aortic valve. The body includes a lumen extending through the body from a proximal end to a distal end of the body; and an adjustable frame surrounding the lumen. The prosthetic implant further includes at least one adjustable element located in or on the body and extending at least partially around a circumference of the lumen. The at least one adjustable element includes a shape memory material and is transformable, in response to application of an activation energy, from a first configuration to a second configuration, wherein the first configuration and second configuration differ in a size of at least one dimension of the at least one adjustable element. The at least one adjustable element may engage at least one of a root of the aorta, an annulus of the aortic valve, and the patient's left ventricle, when the at least one adjustable element is in the second configuration.

摘要： Implants for treatment of obesity may be placed within the stomach and/or esophagus or around the outside surface of the stomach and/or esophagus. The implants comprise at least a portion constructed of a shape memory material. The implants are thus adapted to be implanted in a deformed shape, and then to be transformed through the application of activation energy into a memorized shape. The shape and/or size transformation induces a change in shape of the stomach and/or esophagus, thus altering the normal digestive path of food entering the patient's gastrointestinal tract.

摘要： An adjustable annuloplasty device is described. The device includes a body member comprising a shape memory material, the body member configured to be placed at or near a base of a valve of a heart. The device further includes a hysteretic material configured to undergo magnetic hysteresis in response to a first activation energy, the hysteretic material being in thermal communication with the shape memory material. The body member may have a first size of a body member dimension in a first configuration and a second size of the body member dimension in a second configuration. When the body member is in position in the heart, a change from the first configuration to the second configuration changes a size of a dimension of the annulus of the valve.

摘要： Methods and devices are provided for treatment of an aneurysm within a patient. 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, the size and/or shape of the embolic coils can be adjusted to provide optimal filling of the aneurysm. 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 embolic coil.

摘要： Disclosed is a device and method for accessing the lower esophageal sphincter through the esophagus. In one embodiment, a catheter is inserted through the mouth or nose of a patient and advanced to the region of the diaphragm. Under fluoroscopy or endoscopy, a hollow needle at the distal end of the catheter punctures the wall of the esophagus from the inside so that the distal end of the needle is positioned outside the esophagus. An implant is next advanced out through the hollow needle to the region outside the sphincter where it is deflected and coerced to bluntly dissect around the circumference of the esophagus, where the implant is left in place to heal. The hollow needle is removed and the esophageal wall is allowed to heal. Subsequent diametric adjustment of the implant allows for tightening or loosening of the sphincter to minimize gastric reflux. The device and method can also be used to treat the pyloric or other body sphincters, hollow organs, or ducts.

摘要： Gastroesophageal implants are implantable at or near the gastroesophageal junction in order reinforce the lower esophageal sphincter and prevent gastric reflux. In a contracted configuration, the implants prevent or substantially restrict communication between the stomach and the esophagus. In an open configuration, the implants do not substantially restrict communication between the stomach and the esophagus. Certain embodiments of the implants are capable of detecting various conditions of the esophagus and/or stomach and moving between the contracted and open configurations in response to the detected condition(s).

摘要： A patch electrode of the type which is surgically attached to the epicardium for use in an implantable arrhythmia treatment system is disclosed which has one or more regions of exposed electrode mesh on a side of the electrode in direct contact with the epicardium. The mesh is held in a flexible carrier having a periphery between the exposed mesh and the edge of the carrier. A layer of a drug or steroid is carried on the carrier in this peripheral region, the drug or steroid interacting with body fluid and thereby slowly releasing into the surrounding tissue. The drug or steroid may be selected to provide antiarrhythmia therapy, reduce inflammation, retard tissue growth or may be an antimicrobial drug. The layer carried on the carrier may be on surface thereof, contained in a shallow trough in the carrier, or impregnated within the carrier material. The layer may be carried on one or both sides of the carrier.
