Abstract: In some embodiments, an apparatus includes a catheter having a catheter body, a light emitter disposed at a distal end of the catheter body, and a fluid conduit coupleable to a source of fluid. The fluid conduit configured to discharge fluid from the source via the conduit and out a distal end of the catheter body. A spacing member is disposed at the distal end of the catheter body and can be moved between a collapsed configuration and an expanded configuration. In the expanded configuration, the spacing member is disposed about the light emitter. The spacing member is at least partially transmissive and/or transflective of light emitted from the light emitter. The apparatus configured to be inserted at least partially into a body lumen, to discharge fluid into the body lumen, and to emit light from the light emitter to illuminate an interior wall of the body lumen.

Abstract: An RF ablation system includes an electrode element of elongate form and a cathode pad. A control unit includes a processing unit, a power unit and, optionally, a temperature sensor and/or an impedance sensor. The control unit in one embodiment carries out RF ablation in at least two phases, the first phase at a higher energy level and a second phase, after at least partial retraction of the anode element, at a second lower phase in order to close any remaining lumen within a blood clot formed within the vessel during the first phase. Other embodiments provide for sensing retraction of the anode terminal and effecting RF ablation during and/or after the retraction process in order to create a more effective occlusion barrier.

Abstract: The present disclosure provides for a device and methods of use to endoluminally ablate and/or occlude a body vessel using a radiofrequency (“RF”) signal. The device has two conductive elements or electrodes that form various electrical circuits, and the two conductive elements are operable to create an electrical field. The electrical field ablates the body vessel, forming an occlusion.

Abstract: The present disclosure provides for a device and methods of use to endoluminally ablate and/or occlude a body vessel using a radiofrequency (“RF”) signal and a current to perform resistive heating. The device may have a RF mode and a resistive mode, and may perform each mode in sequential order until the vessel is fully occluded. The device further comprises a control unit to operate the device in its various modes. The device may be provided with a dielectric coating to create a low-friction tip or coil.
