摘要:
Uterine artery occlusion is performed for the treatment of uterine fibroid using a tool which is introduced through the vaginal wall to the exterior of the uterus. The tool carried clamping elements which may be positioned over the uterine artery. Electrodes or other energy applying devices on the clamping elements may be used to deliver energy to seal the uterine artery. Optionally, the tool may carry ultrasonic, visual, or proximity sensors for detecting the presence of the uterine artery prior to delivering energy.

摘要:
One method for performing procedures, such as vaginal hysterectomies, comprises engaging first and second energy transmitting elements against a lateral side of a uterus. The first and second energy transmitting elements are positioned against opposed surfaces of a tissue mass extending from and including a fallopian tube or round ligament to a tip of a cervix. Third and fourth energy transmitting elements are positioned against another lateral side of the uterus and against opposed surfaces of another tissue mass extending from and including another fallopian tube or round ligament to the tip of the cervix. Radio frequency or other high energy power is applied through the energy transmitting elements to the tissue masses. The power is applied for a time and in an amount sufficient to coagulate and seal the tissue masses within the energy transmitting elements. The coagulated tissue masses are then resected and the entire uterus removed.

Devices and methods are provided for treatment of tissue in a body lumen with an electrode deployment device. Embodiments typically include a device with a plurality of electrodes having a pre-selected electrode density arranged on the surface of a support. The support may comprise a non-distensible electrode backing that is spirally furled about an axis and coupled to an expansion member such as an inflatable elastic balloon. In some embodiments, the balloon is inflated to selectively expose a portion of the electrode surface while maintaining the electrode density.

摘要:
A system for measuring physiologic characteristics for treating abnormal mucosa in the esophagus comprises a sizing device having an inflatable balloon on a distal end of a catheter that is inflated with an expansion medium to expand the balloon to engage the wall of the esophagus so that the internal cross-section can be calculated or measured. The sizing device may also include an infusion source for delivering the expansion medium and means for measuring the amount and pressure of the expansion medium inside the catheter. The system also comprises one or more energy delivery devices for injuring or ablating the
摘要:
A method and apparatus for treating abnormal mucosa in the esophagus is disclosed, such that the depth of the treated tissue is controlled. The depth of ablation is controlled by monitoring the tissue impedance and/or the tissue temperature. A desired ablation depth is also achieved by controlling the energy density or power density, and the amount of time required for energy delivery. A method and apparatus is disclosed for measuring an inner diameter of a body lumen, where a balloon is inflated inside the body lumen at a fixed pressure.
