    摘要： A surgical wound retractor is adapted to dilate a wound stretchable to a desired diameter, the retractor includes a first ring having a diameter greater than that desired for the wound and being adapted for disposition interiorly of the wound. A second ring has a diameter greater than that desired for the wound and is adapted for disposition exteriorly of the wound. A plurality of retraction elements are disposed in a generally cylindrical relationship to each other, between the first ring and the second ring. These elements extend through the wound to exert a radial retraction force on the wound which is dependent on the distance separating the first ring and the second ring. Retraction elements, both distensible and non-distensible are contemplated with appropriate attachment elements at the rings to provide for variations in the retraction force. With a suitable retraction sleeve, a third ring can be provided to form a circumferential retainer to vary the retraction force. Rings can also be made inflatable or self-expanding to vary the retraction force. An associated method includes the step of rolling the second ring circumferentially of the third ring to form the circumferential retainer.

    摘要翻译： 外科伤口牵开器适于将可拉伸至期望直径的伤口扩张，牵开器包括直径大于伤口所需直径的第一环，并适于在伤口内部配置。 第二环的直径大于伤口所需的直径，并且适于在伤口的外部配置。 多个退回元件在第一环和第二环之间以大致圆柱形的关系设置。 这些元件延伸穿过伤口以在伤口上施加径向缩回力，这取决于分离第一环和第二环的距离。 缩回元件，既可扩张也不可扩张，可以考虑在环处的适当的附接元件，以提供收缩力的变化。 利用合适的缩回套筒，可以提供第三环以形成圆周保持器以改变收回力。 环也可以制成充气或自膨胀以改变收缩力。 相关联的方法包括在第三环周向滚动第二环以形成周向保持器的步骤。

    摘要： Apparatus and methods are provided for placing and advancing a diagnostic or therapeutic instrument in a hollow body organ of a tortuous or unsupported anatomy, comprising a handle, an overtube, a distal region having an atraumatic tip. The overtube may be removable from the handle, and have a longitudinal axis disposed at an angle relative to the handle. The overtube may be selectively stiffened to reduce distension of the organ caused by advancement of the diagnostic or therapeutic instrument. The distal region permits passive steering of the overtube caused by deflection of the diagnostic or therapeutic instrument while the atraumatic tip prevents the wall of the organ from becoming caught or pinched during manipulation of the diagnostic or therapeutic instrument.

    摘要： A stent having an elongate tubular configuration is formed of a plurality of elongate elements interwoven or braided to form a tubular configuration. The elements may be relatively strong and rigid, but movable relative to each other within the weave or braid in order to provide the stent with generally soft characteristics. The elements may be formed of different materials, such as an absorbent material permitting the stent to be doped with materials such as drugs and chemicals. Even the absorbency can be controlled and varied to provide a predetermined time-release of the absorbent.

    摘要： Methods for percutaneous hernia repair may include inserting a needle end of an anchor tool through a first tissue edge on a first side of a hernia defect opening. A first anchor is deployed with a first suture attached to the first anchor and running back through or along the anchor tool and outside of the patient's body. The needle end of the anchor tool is withdrawn from the first tissue edge. The first suture is separated from the anchor tool. The needle end of an anchor tool is inserted through a second tissue edge and a second anchor is deployed, with a second suture attached to the second anchor and running back through or along the anchor tool and outside of the patient's body. The sutures are tensioned and cinched or knotted.

    摘要： Devices and methods for endolumenally manipulating stomach fundus tissue alter the function of nearby nerves. The altered function of the nerves interacts with the cardiopulmonary system to cause a substantially permanent reduction in blood pressure. The altered nerve function may also treat heart disease as well. This application also relates to devices and methods for endolumenally manipulating stomach tissue to alter hormone production from cells associated with stomach tissue, providing a therapeutic effect in treating hypertension and heart disease, not conventionally associated with the stomach.

    摘要： Methods and apparatus for securing and deploying tissue anchors are described herein. A tissue manipulation assembly is pivotably coupled to the distal end of a tubular member. A reconfigurable launch tube is also pivotably coupled to the tissue manipulation assembly, which may be advanced through a shape-lockable endoscopic device, a conventional endoscope, or directly by itself into a patient. A second tool can be used in combination with the tissue manipulation assembly to engage tissue and manipulate the tissue in conjunction with the tissue manipulation assembly. A deployment assembly is provided for securing engaged tissue via one or more tissue anchors, the deployment assembly also being configured to disengage the anchors endoluminally or laparoscopically by applying thermal energy through at least one suture cutting element disposed along the deployment assembly.
