摘要:
A tissue ablation apparatus includes a delivery catheter with distal and proximal ends. A handle is attached to the proximal end of the delivery catheter. At least partially positioned in the delivery catheter is an electrode deployment device. The electrode deployment devices includes a plurality of retractable electrodes. Each electrode has a non-deployed state when it is positioned in the delivery catheter. Additionally, each electrode has a distended deployed state when it is advanced out of the delivery catheter distal end. The deployed electrodes define an ablation volume. Each deployed electrode has a first section with a first radius of curvature. The first section is located near the distal end of the delivery catheter. A second section of the deployed electrode extends beyond the first section, ad has a second radius of curvature, or a substantially linear geometry.
摘要:
An RF treatment apparatus includes a catheter with a catheter lumen. A removable needle electrode is positioned in the catheter lumen in a fixed relationship to the catheter. The needle electrode includes a needle lumen and a needle electrode distal end. A removable introducer is slidably positioned in the needle lumen. The introducer includes an introducer distal end. A first sensor is positioned on a surface of the needle electrode or the insulator. An RF power source is coupled to the needle electrode and a return electrode. An insulator sleeve is slidably positioned around the electrode and includes a second sensor. Resources are associated with the electrodes, sensors as well as the RF power source for maintaining a selected power at the electrode independent of changes in current or voltage.
摘要:
Devices, systems and methods employ magnetic force to resist tissue collapse in targeted pharyngeal structures and individual anatomic components within the pharyngeal conduit during sleep.
摘要:
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.
摘要:
Systems and related methods stabilize tissue in an airway using material which is sized and configured to be fitted to surface tissue in the airway and which is magnetically attracted toward a magnetized material to stabilize a preferred tissue orientation. The systems and related methods can be used, e.g., to treat snoring and other sleep related disorders.
摘要:
Systems and related methods treat snoring and other sleep related disorders by stabilizing the position of a tongue in an oral cavity. 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 a tongue in the airway to stabilize a preferred tissue orientation. The operative element can comprise a suction source sized and configured to draw more mobile tongue tissue toward the suction source. The operative element can comprise a magnetic source sized and configured to magnetically attract material fitted to more mobile tongue tissue in the airway.
