摘要： A structure that can be used as a gastric band (and that may also have other uses as an implant elsewhere in a patient) includes a plurality of magnetic elements in a serial array that can be implanted so that the array extends in a circumferential direction around the patient's stomach (or other body tissue structure in the patient). Circumferentially adjacent magnetic elements magnetically attract one another to apply radial pressure to the tissue structure encompassed by the array, but those elements can also move apart in response to sufficient outward pressure from the encompassed tissue structure and/or the contents of (e.g., food in) that tissue structure. When used as a gastric band, the device can provide resistance to excessive food intake, which can help promote weight loss.

摘要： A plurality of structures that resiliently attract one another are provided for implanting in a patient around a body tissue structure of the patient. For example, the body tissue structure may be the esophagus, and the plurality of structures may be implanted in an annulus around the outside of the esophagus, the annulus being substantially coaxial with the esophagus. The attraction may be between annularly adjacent ones of the structures in the annulus, and it may be provided, for example, by magnets or springs. The array of structures is preferably self-limiting with respect to the smallest area that it can encompass, and this smallest area is preferably large enough to prevent the apparatus from applying excessive pressure to tissue passing through that area.

摘要： Devices and methods for sealing a passageway formed by a patent foramen ovale (PFO track) in the heart are provided. One method includes providing an abrading device to the PFO track and abrading the tissue within the PFO track. The abraded tissue forming the PFO track is then held together under pressure, either via lowering right atrial pressure or via applying suction to the septum primum to pull it into apposition against the septum secundum. After a sufficient period of time, the pressure is released and the abraded tissue heals to form a robust seal over the PFO track. Additionally, several devices are provided which can be placed into the PFO track to apply adhesive to the walls of the PFO track. The devices may or may not be left within the PFO track. If the devices are not left within the PFO track, the walls of the PFO track, covered with adhesive, are brought into apposition with one another and adhered together. If the device is left within the PFO track, the device is flattened from an expanded configuration to a flattened configuration, and the walls of the PFO track, adhering to the outer surface of the device, are pulled toward each other as the device flattens. The device may also include interior structure to hold the device in a flattened configuration.

摘要： A closure device for sealing a patent foramen ovale (PFO) in the heart includes a left atrial anchor adapted to be placed in a left atrium of the heart, a tether fixedly connected to the left atrial anchor and adapted to extend through the passageway of the PFO, a right atrial anchor adapted to be placed in a right atrium of the heart and moved along the tether, and a lock for securing the position of the right atrial anchor along the tether. The left and right atrial anchors preferably include a plurality of arms formed as loops and may include means for securing each arm in case of fracture in the loop. After the closure device is positioned, a cutting tool may sever the portion of the tether proximal of the right atrial anchor. The closure device can be retrieved during delivery, including by use of a snare catheter.
