    摘要： A method and apparatus for controlling the extent of tissue ablation are disclosed. The method utilizes delivering energy from an energy deliver device to a plurality of deployed electrodes and regulating energy delivered to the electrodes based on the temperature sensed by at least one remote elongate sensor element. A control device may be used to supply energy to the electrodes, to produce tissue ablation that advances from individual-electrode ablation regions to fill a combined-electrode ablation volume. Information from the sensor element(s) is used for determining the extent of ablation in the regions of the sensor elements. The supply of energy to the electrodes can thus be regulated to control the level and extent of tissue ablation throughout the combined-electrode volume.

    摘要翻译： 公开了一种用于控制组织消融程度的方法和装置。 该方法利用将能量从能量传递装置传送到多个展开的电极，并且基于由至少一个远程细长传感器元件感测的温度来调节传递到电极的能量。 可以使用控制装置向电极提供能量，以产生从单个电极消融区域前进以填充组合电极消融体积的组织消融。 来自传感器元件的信息用于确定传感器元件区域中的消融程度。 因此，可以调节对电极的能量供应以控制整个组合电极体积中的组织消融的水平和程度。

    摘要： Described herein is a positioning tool having an elongate portion for carrying a medical implant. Also described is a method of positioning a medical implant using an elongate positioning tool. One form of the method includes positioning a medical implant on a distal portion of an elongate positioning tool, inserting the positioning tool with the implant thereon into a body cavity manipulating the positioning tool to position the implant into contact with tissue at an attachment location, attaching the implant to surrounding tissue at the attachment location, separating the implant from the positioning tool, and withdrawing the positioning tool from the body. In a preferred embodiment, the position of the implant is visually confirmed using an endoscope before the implant is attached to surrounding tissue. In one embodiment, the implant is a satiation device and the body cavity is the esophagus and/or stomach. In an alternative embodiment, an expansion structure on the distal end of the elongate portion expands and/or contracts the medical implant to facilitate positioning.

    摘要： Described herein are endoscopic plicators passed transorally into the stomach and used to plicate stomach tissue by engaging tissue from inside of the stomach and drawing it inwardly. In the disclosed embodiments, the tissue is drawn inwardly into a vacuum chamber, causing sections of serosal tissue on the exterior of the stomach to be positioned facing one another. The disclosed plicators allow the opposed sections of tissue to be moved into contact with one another, and preferably deliver sutures, staples or other means for maintaining contact between the tissue sections at least until serosal bonds form between them. Each of these steps may be performed wholly from the inside of the stomach and thus can eliminate the need for any surgical or laparoscopic intervention. After one or more plications is formed, medical devices may be coupled to the plication(s) for retention within the stomach.

    摘要： A tissue surface treatment apparatus includes a housing having a proximal end, a distal end including a tissue contacting surface, an interior defined by the housing and a handpiece coupled to the housing. The contactinc surface has a plurality of apertures. An energy delivery device including an electrode is positionable in the housing interior. The electrode includes a tissue penetrating distal end in substantial alignment with an aperture. The electrode is configured to be advanced from the housing interior through the aperture and into a target tissue site to define an ablation volume at least partly bounded by a tissue surface. An advancement device is coupled to the energy delivery device and is at least partly positionable within at least one of the housing or the handpiece. The advancement device is configured to advance the electrode from the housing interior into the target tissue site and withdrawal the electrode into the housing interior. A cable is coupled to the housing or the energy delivery device and is configured to be coupled to an energy source.
