    摘要: A medical probe for the heating of soft tissue, such as collagen tissue, wherein the medical probe has an elongated body with a proximal and distal end, a heating source, an RF electrode. Optional components include a thermocouple, and an insulative sleeve. The probe's elongated body is preferably hollow and flexible. The RF electrode and the heating source are powered by independently controlled power sources and cooperate to maintain a constant and smooth temperature to the distal end of the RF electrode. The heating source may be a contained liquid, such as saline, or an electrothermal mass, such as a ferrite, a toroid, a resistive element, or the like. Current induced from the conductor to the heating source creates heat in the heating source. The thermocouple measures the temperature of the heating source and adjusts the power to the conductor to maintain the heating source's temperature.

    摘要: An electrosurgical aspiration instrument that permits aspiration of an area being treated by the instrument. The instrument is coupled at a proximal end to a power source and includes an energy application surface area at a distal end. The power source supplied energy to the energy application surface area such that the distal end of the instrument may apply energy to the treatment area to modify the characteristics of biological material, such as biological tissue in the area. An aspiration lumen is formed through the instrument with an opening through the energy application surface area. The energy application surface area is configured to reduce blockage of the opening. Accordingly, aspiration may be performed simultaneously with electrosurgical treatment whereby unwanted matter such as by-products, biological debris and excess fluid is removed from the treatment area. The electrosurgical aspiration instrument also permits both functions to be performed at different times, with the advantage of not requiring instruments to be switched on during the treatment procedure or removed from the treatment site.

    摘要: An electrode catheter assembly for ablation of obstructive material formed within and around a stent inserted within a lumen includes an elongate flexible tube having a distal end and a proximal end, and an electrode assembly attached to the distal end of the tube. The electrode assembly includes: a first electrode formed by a cylindrical body defining a longitudinal axis and having a first end, and an opposite second end, the body having a plurality of slits formed therein, each of the slits extending parallel to the axis from a corresponding first point proximate the first end to a corresponding second point proximate the second end, the slits defining a plurality of elongated deformable segments; and a second electrode disposed along the axis at a distance from the first electrode. A spacer means, disposed between the first and second electrodes, is operative to physically separate and electrically insulate the first electrode from the second electrode. Electrical transmission means provides a first electrical path between a power supply and the first electrode, and a second electrical path between the second electrode and the power supply. Actuator means is provided for moving the first end toward the second end of the body causing the segments to be deformed so that portions thereof are extended radially away from the axis, whereby when the catheter assembly is inserted into a lumen and positioned within an occluded stent, the deformable segments establish an electrically conductive path to the stent.

The coil includes a central aperture which may be adjustable between a first configuration and a second configuration having a radius greater than the radius of the first configuration. The adjustable or movable nature of the coil allows the conductive coil to conform to, accommodate, or be positioned on a particular anatomical structure of a patient to position the coil in proximity to the underlying target nerve. In certain embodiments, methods of magnetic induction therapy are provided which include positioning a conductive coil relative to a portion of a patient's body by adjusting the central aperture of the coil such that the coil may conform to, accommodate or be positioned on the portion of the patient's body in proximity to the underlying target nerve.
