  • Publication number: 20090025734
    Abstract: Systems and methods employ implants attached to the hyoid bone, thyroid cartilage, cricoid cartilage, or both the thyroid and cricoid cartilages and a source of magnetic force to move the hyoid bone, thyroid cartilage, cricoid cartilage, or both the thyroid and cricoid cartilages in the treatment of sleep disordered breathing, using attracting, repelling or a combination of attracting and repelling magnetic forces.

  • Patent number: 7449020
    Abstract: 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.

  • Patent number: 7387626
    Abstract: A medical probe device comprises a catheter having a stylet guide housing with one or more stylet ports in a side wall thereof and a stylet guide for directing a flexible stylet outward through the stylet port and through intervening tissue at a preselected, adjustable angle to a target tissue. The total catheter assembly includes a stylet guide lumen communicating with the stylet port and a stylet positioned in said stylet guide lumen for longitudinal movement from the port through intervening tissue to a target tissue. The stylet can be an electrical conductor enclosed within a non-conductive layer, the electrical conductor being a radiofrequency electrode. Preferably, the non-conductive layer is a sleeve which is axially moveable on the electrical conductor to expose a selected portion of the electrical conductor surface in the target tissue. The stylet can also be a microwave antenna. The stylet can also be a hollow tube for delivering treatment fluid to the target tissue.

  • Patent number: 7367340
    Abstract: Systems and methods selectively stabilize tissue in the oral cavity. The systems and methods implant a first implant element in a bone region within an oral cavity and implant a second implant element in a tongue region within the oral cavity. The systems and methods resist posterior movement of the tongue within the oral cavity by coupling the first implant element to the second implant element within the oral cavity. By coupling, the systems and methods apply force, e.g., tension, between the first and second implant elements.

  • Patent number: 7216648
    Abstract: Systems and related methods stabilize tissue in the oral cavity and airway, e.g., the soft palate/uvula and/or tongue. The systems and methods employ an operative element sized and configured to be fitted to less mobile tissue in the oral cavity. The operative element is further constructed and arranged to interact with more mobile tissue in the airway to stabilize a preferred tissue orientation. The operative element can comprise a suction source sized and configured to draw more mobile tissue toward the suction source. Alternatively, the operative element can comprise a magnetic source sized and configured to magnetically attract material fitted to more mobile tissue in the airway.
