摘要： A medical probe device comprises a catheter having a stylet guide housing with one or more stylet ports in a side wall thereof and a stylet guide 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 radiofrequency electrode. Preferably, the non-conductive layer is a sleeve which is axially moveable on the electrical conductor to expose a selected portion of the electrical conductor surface in the target tissue. The stylet can also be a microwave antenna. The stylet can also be a hollow tube for delivering treatment fluid to the target tissue. It can also include a fiber optic cable for laser treatment. The catheter can include one or more inflatable balloons located adjacent to the stylet port for anchoring the catheter or dilation. Ultrasound transponders and temperature sensors can be attached to the probe end and/or stylet. The stylet guide can define a stylet path from an axial orientation in the catheter through a curved portion to a lateral orientation at the stylet port.

The infusion array includes an RF electrode and at least a first and a second infusion member. Each infusion member has a tissue piercing distal portion and an infusion lumen. At least one of the first or second infusion members is positionable in the elongated delivery device in a compacted state and deployable from the elongated delivery device with curvature in a deployed state. Also, at least one of the first or second infusion members exhibits a changing direction of travel when advanced from the elongated delivery device to a selected tissue site. At least one infusion port is coupled to one of the elongated delivery device, the infusion array, the first infusion member or the second infusion member.

摘要： A method for treating a sphincter provides a polymer material having a liquid state. The method also provides a catheter having a distal end, a tissue piercing device carried by the distal end, and an energy delivery device coupled to the tissue piercing device. The tissue piercing device has a lumen. The method introduces the catheter into an esophagus and pierces an exterior sphincter tissue surface within with the tissue piercing device. The method advances the tissue piercing device into an interior sphincter tissue site and conveys the polymer material while in a liquid state through the lumen into the interior sphincter tissue site. The method delivers energy to the tissue piercing device to transform the polymer material into a less liquid state within the interior sphincter tissue site, to thereby remodel the sphincter.

摘要： An apparatus and method are provided for control contraction of tissue that includes collagen fibers. The apparatus includes a handpiece, and an electrode with an electrode proximal end associated with the handpiece. A distal end of the electrode has a geometry that delivers a controlled amount of energy to the tissue for a desired contraction of the collagen fibers. This is achieved while dissociation and breakdown of the collagen fibers is minimized. The handpiece, with electrode, is adapted to be introduced through an operating cannula in percutaneous applications. Additionally, an operating cannula may be included in the apparatus and be attached to the handpiece. The apparatus and method provides for a desired level of contraction of collagen soft tissue without dissociation or breakdown of collagen fibers.

摘要： A sphincter treatment apparatus includes an energy delivery device introduction member including a proximal end with a first radius of curvature and a distal end with a second radius of curvature. The introduction member is configured to be introduced into the sphincter in a non-deployed state and to be expanded to a deployed state to at least partially expand the sphincter or an adjoining structure. An energy delivery device is coupled to the introduction member. A retainer member is coupled to the energy delivery device introduction member and configured to controllably position the introduction member in an orifice of the sphincter.

摘要： Systems and methods treat a tissue region at or near a sphincter by deploying a carrier, which carries an electrode that can be advanced to penetrate tissue. Negative pressure is applied through a suction port on the carrier near the electrode, to draw tissue in the tissue region inward against the carrier. The systems and methods advance the electrode to penetrate tissue drawn against the carrier. The vacuum anchors the surrounding tissue and mediates against the “tenting” of tissue during electrode penetration. Without tenting, the electrode penetrates mucosal tissue fully, to obtain a desired depth of penetration.

摘要： A device for introducing a catheter into a vessel through a puncture in a vessel and for sealing the puncture. The device includes an elongated body having a proximal end and a distal end sized to be positioned within a tissue site which includes the puncture. The elongated body includes a utility lumen sized to allow a catheter to be delivered through the utility lumen. The utility lumen is positioned within the elongated body so positioning the elongated body within the tissue site allows a catheter delivered through the utility lumen to enter the vessel. The elongated body also includes a closure lumen having an entrance port. A closure composition can be delivered through the entrance port into the closure lumen. The closure lumen also includes an exit port adjacent the distal end of the elongated body. The closure composition delivered into the closure lumen can be delivered through the exit port to the tissue site adjacent the puncture.
摘要翻译：一种用于通过穿孔在容器中将导管引入容器并用于密封穿刺的装置。该装置包括细长体，其具有近端和远端，其尺寸设置成包括穿刺的组织部位内。细长主体包括大小适于允许导管通过效用管腔输送的应用腔。实用管腔定位在细长体内，从而将细长体定位在组织部位内，允许通过效用腔输送的导管进入血管。细长体还包括具有入口的封闭腔。封闭组合物可通过入口端口输送到封闭腔。闭合腔还包括邻近细长体的远端的出口。输送到闭合腔内的封闭组合物可以通过出口传送到穿刺附近的组织部位。
