Abstract: A device carries a use monitoring element that possesses a state or condition that changes in response to use of the device and that is sensed when the device is presented for use. Reuse of the device is not permitted, if the use monitoring element indicates a prior use.

Abstract: Systems and methods deploy an electrode structure in contact with the tissue region. The electrode structure carries a sensor at a known location on the electrode structure to monitor an operating condition. The systems and methods provide an interface, which generate an idealized image of the electrode structure and an indicator image to represent the monitored operating condition in a spatial position on the idealized image corresponding to the location of the sensor on the electrode structure. The interface displays a view image comprising the idealized image and indicator image. The systems and methods cause the electrode structure to apply energy to heat the tissue region while the view image is displayed on the display screen.

Abstract: A usage key card is adapted to be handled separate from a tissue treatment device. The usage key card has a storage medium formatted to contain an identification code, which is unique to the usage key card. The usage key card is also adapted to be read by a reader separate from the device. The storage medium is also formatted, when inserted into the reader, to retain data generated pertaining to operation of the device.

Abstract: A device for treating a tissue region is supplied with a separate usage key card. The usage key card comprises a storage medium, which is formatted to contain an identification code unique to the usage key card. The usage key card is adapted to be read by a remote reader, to download the identification code for processing by a controller for the device. Processing of the identification code by the controller either enables or disables operation of the device according to prescribed criteria. A viewable image is generated on a display screen that changes in response to processing of the identification code.

Abstract: Unified systems and methods enable control of the use and operation of a family of different treatment devices, to treat dysfunction in different regions of the body.

Abstract: A system comprising a storage medium associated with a device for treating a tissue region, the device including a handle, a catheter tube extending from the handle, a temperature sensor and a basket including a plurality of spines, the spines carrying an electrode for delivering treatment energy to a tissue site. The temperature sensor senses temperature near a distal end of the electrode. The basket is movable between a non-expanded low profile condition and an expanded condition and the electrode is movable from a first position to an extended position. The storage medium is formatted to contain an identification code uniquely assigned to the device for registration of the device if absence of prior use is determined.

Abstract: A device for treating a tissue region at or near a lower esophageal sphincter to treat gastroesophageal reflux disease including a flexible tube having a plurality of arrays of first and second lumens, a proximal base, a distal hub, a plurality of radially spaced slits formed between the proximal base and distal hub, and a plurality of electrode ports and fluid ports, the electrode and fluid ports and the lumens are positioned between the slits. The tube is flexible outwardly between the slits to form an array of spines forming a three dimensional basket. A first electrode is movable within the first lumen of one array and a second electrode is movable within the first lumen of another array to exit through the electrode ports to penetrate tissue for application of energy to the tissue region to tighten the lower esophageal sphincter to treat gastroesophageal reflux disease.

Abstract: A device for treating a tissue region at or near a sphincter including a proximal support, a distal support and an expandable basket having a plurality of spines. The spines have a proximal portion, a distal portion and an intermediate portion therebetween, wherein the spines are movable from a first non-expanded position to a second expanded position wherein in the expanded position the intermediate portion of the spines extends outwardly radially beyond the proximal and distal portions of the spines. A plurality of electrodes are carried by the spines and movable outwardly to an outward position to penetrate tissue for application of energy to the tissue region.
