摘要： A thermal energy delivery apparatus has a probe including a distal end and a proximal end. A first electrode is positioned at the distal end of the probe. The first electrode is configured to deliver sufficient thermal energy to a fibrillated cartilage surface to reduce a level of fibrillation of the fibrillated cartilage surface. A cabling is coupled to the proximal end of the probe. A method for thermal protection of non-targeted tissues that may be exposed to thermal probes used during arthroscopic procedures includes a pre-procedural cooling Lavage. The pre-cooled tissues provide a convective buffer for tissues not intended for thermal intervention, thereby reducing collateral damage.

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.

摘要： A radio frequency device for use on a human to resurface skin having collagen therein. The device includes a handle member having an end portion adapted for engaging the skin. At least one passageway extends through the handle member to an opening at the end portion. An electrically conductive liquid is supplied through the passageway to the opening. An electrode is carried by the end portion in communication with the passageway. Radio frequency energy supplied to the electrode causes the collagen in the skin to contract and thus tighten the skin.

摘要： A medical probe apparatus comprising a catheter having a stylet guide housing with one or more stylet ports therein and stylet guides for directing one or more flexible stylets outward through respective stylet ports and through intervening tissue to target tissue. The active stylets emit radio frequency RF energy which establishes an RF current in the patient. The current, being densest at the stylet tips, causes heating of the surrounding tissue to initiate ablation of the target tissue. One aspect of the invention includes temperature sensing stylets at the location of the RF emitting stylets to monitor the temperature of the tissue being ablated. This allows the surgeon to have increased knowledge about the abating action under way in order to control the intensity of the applied RF current, or to adjust the amount of time the current is applied, or both. Further included herein is a plurality of temperature sensors mounted on an ultrasound probe to be used to monitor tissue temperature at the ultrasound probe while allowing the ultrasound device to monitor the position and orientation of the medical probe apparatus of the present invention.

摘要： A medical probe device of this invention comprising a catheter having a control end and a probe end. The probe end includes a stylet guide housing having at least one stylet port and stylet guide means for directing a flexible stylet outward through at least one stylet port and through intervening tissue to targeted tissues. A stylet is positioned in at least one of said stylet guide means, the stylet comprising a non-conductive sleeve having a RF electrode lumen and an optional a fluid supply lumen and a temperature sensor lumen therein. At least one portion of an opposed surface of the electrode lumen and the electrode can be spaced apart to define a liquid supply passageway for delivery of medicament liquid. The RF electrode enclosed within the non-conductive sleeve has a distal length optionally having at least one current focusing groove means thereon and a distal tip shaped to focus current crowding on its terminal end, whereby Rf current passing therefrom into surrounding tissue forms a lesion extending outward from the groove and tip. The focusing groove means can be a plurality of annular focusing grooves or a spiral focusing groove thereon.

摘要： A medical probe device including a catheter having a stylet guide housing with one or more stylet ports in a side wall thereof and a 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 radio frequency electrode. During the ablation operation, the tissue immediately adjacent the stylet can become desiccated, thereby necessitating an increase of current flow and a loss of ablation efficiency. A forward and reverse movement of the non-conductive sleeve on the stylet during an operation frees the stylet from sticking tissue and creates a space around the electrode to allow the tissue to rehydrate.

摘要： A medical probe apparatus comprising a catheter having a stylet guide housing with one or more stylet ports therein and stylet guides for directing one or more flexible stylets outward through respective stylet ports and through intervening tissue to target tissue. The active stylets emit radio frequency RF energy which establishes an RF current in the patient. The current, being densest at the stylet tips, causes heating of the surrounding tissue to initiate ablation of the target tissue. One aspect of the invention includes temperature sensing stylets at the location of the RF emitting stylets to monitor the temperature of the tissue being ablated. This allows the surgeon to have increased knowledge about the abating action under way in order to control the intensity of the applied RF current, or to adjust the amount of time the current is applied, or both. Further included herein is a plurality of temperature sensors mounted on an ultrasound probe to be used to monitor tissue temperature at the ultrasound probe while allowing the ultrasound device to monitor the position and orientation of the medical probe apparatus of the present invention.
