| 20090076438 | Method for treating a sphincter - A method for treating a sphincter provides a polymer material having a liquid state. The method also provides a catheter having a distal end, a tissue piercing device carried by the distal end, and an energy delivery device coupled to the tissue piercing device. The tissue piercing device has a lumen. The method introduces the catheter into an esophagus and pierces an exterior sphincter tissue surface within with the tissue piercing device. The method advances the tissue piercing device into an interior sphincter tissue site and conveys the polymer material while in a liquid state through the lumen into the interior sphincter tissue site. The method delivers energy to the tissue piercing device to transform the polymer material into a less liquid state within the interior sphincter tissue site, to thereby remodel the sphincter. | 03-19-2009 |
| 20090093805 | Systems and methods for monitoring and controlling use of medical devices - A usage key card is adapted to be handled separate from a device tissue treatment deice. 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 de | 04-09-2009 |
| 20090254079 | Methods for treating the cardia of the stomach - Methods treat a tissue region. In one arrangement, the methods deploy an endoscope in an esophagus and visualize with the endoscope a Z-line that marks a transition between esophageal tissue and stomach tissue by observing tissue color change at or near the Z-line. The methods deploy an electrode support structure over the endoscope at or near the Z-line visualized by the endoscope, wherein the endoscope serves as a guide for the electrode support structure. The methods introduce from the electrode support structure a tissue-piercing needle electrode into tissue at or near the Z-line and observe introduction of the tissue-piercing needle electrode using the endoscope. The methods couple the tissue-piercing electrode to a source of radio frequency energy to ohmically heat tissue and create a subsurface tissue lesion in tissue at or near the Z-line, and observe creation of the tissue lesion using the endoscope. | 10-08-2009 |
| 20100063495 | SYSTEM FOR TISSUE ABLATION - Systems for treating a mucosal surface of an alimentary canal tissue region are provided. The systems can include an elongate support structure, an expandable member positionable at a distal portion of the support structure and one or more radio frequency (RF) ablation electrodes carried by the expandable member. The elongate support structure and the expandable member can be adapted to place the one or more electrodes in contact with a mucosal surface of an alimentary canal tissue region. The system can further include an RF energy source connected to the one or more electrodes. | 03-11-2010 |
| 20110098698 | Systems and methods for monitoring and controlling use of medical devices - 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. | 04-28-2011 |
