    摘要： A method of making a radially expandable fluid delivery device includes providing a tube of biocompatible fluoropolymer material with a predetermined porosity based on an extrusion and expansion forming process, applying a radial expansion force to the tube expanding the tube to a predetermined diameter dimension, and removing the radial expansion force. The tube is radially inelastic while sufficiently pliable to be collapsible and inflatable from a collapsed configuration to an expanded configuration upon introduction of an inflation force, such that the expanded configuration occurs upon inflation to the predetermined diameter dimension. The fluid delivery device is constructed of a microporous, biocompatible fluoropolymer material having a microstructure that can provide a controlled, uniform, low-velocity fluid distribution through the walls of the fluid delivery device to effectively deliver fluid to the treatment site without damaging tissue proximate the walls of the device.

    摘要： A gastric constriction device (160) comprises a sheet (131) extending over part of the wall of the stomach (24). Five bands (151) extend around the stomach (24) to fix the sheet (131) in position relative to the stomach (24). The lower two bands (151) extend from the first side (152) of the sheet (131) around the stomach (24) only partially towards the second side (153). These lower two bands (151) are not fixed to the second side (153). This arrangement results in an unconstricted portion of the stomach (161). In this manner, the device (160) restricts expansion of the majority of the stomach wall while facilitating expansion of this unconstricted portion (161). The unconstricted portion (161) is therefore free to expand or bulge outwardly upon ingestion. This expansion may trigger the feeling of satiation due to the presence of the vagal nerves in this portion (161) of the stomach (24).

    摘要翻译： 胃收缩装置（160）包括在胃（24）的壁的一部分上延伸的片（131）。 五个带（151）围绕胃（24）延伸以将片（131）相对于胃（24）固定在适当位置。 下两个带（151）从片（131）的第一侧（152）围绕胃（24）仅部分地朝向第二侧（153）延伸。 这些较低的两个带（151）不固定到第二侧（153）。 这种布置导致胃的无约束部分（161）。 以这种方式，装置（160）限制胃壁的大部分的膨胀，同时有助于该无约束部分（161）的膨胀。 因此，非限制部分（161）在摄入时可以自由地向外膨胀或膨胀。 由于在胃部（24）的该部分（161）存在迷走神经，所以这种扩张可能引起饱腹感。

    摘要： Described herein are tissue repair implants comprising at least a first layer of peritoneal membrane. The first layer of peritoneal membrane can be located adjacent to a second layer of peritoneal membrane and can be in direct contact with the second layer of peritoneal membrane. Additional layers (e.g., a third or fourth layer) can be included. Where more than one layer is present, the layers can be affixed to one another. For example, a first layer of peritoneal membrane can be attached to the second layer of peritoneal membrane by an adhesive bond, suture, or staple. One or more of the peritoneal membranes can be non-crosslinked, partially crosslinked, or substantially fully crosslinked. Any of the layers of peritoneal membrane may be attached to a wall (e.g., an interior or exterior wall) of an abdominal tissue by an adhesive, suture, and/or staples.

    摘要： A soft tissue implant comprises a condensed surgical mesh having a plurality of monofilament biocompatible fibres 12. Condensing of the fibres reduces the void space between adjacent fibres 12 in the mesh and reduces the surface area of the fibres 12 available for contact with tissue 18. Condensation of the fibres 12 may be achieved by applying mechanical pressure, and/or vacuum, and/or heat to the mesh.

    摘要： A radially deployable covered stent that predictably and dependably expands to an increased diameter state at relatively low deployment pressures while concomitantly minimizing the risk of tearing of the stent covering during expansion. The stent covering includes an inner cover and an outer cover that are bonded together through and around the stent structure to cover the stent. The stent cover is constructed from expanded polytetrafluoroethylene (ePTFE) having a structure of nodes interconnected by fibrils. The stent covering has a radial thickness of at least about 0.008″ and an average internodal distance (IND) of at least about 100 microns when the stent is in the reduced diameter, unexpanded state. The covered stent deploys at an average deployment pressure of less than or equal to about 10 atm. A method for covering a stent structure according to the present invention includes placing a compression member in the form of a tubular sleeve over the outer cover and heating the compressed covered stent to bond the inner cover to the outer cover. An adhesive in the form of an aqueous dispersion of PTFE can be applied to either the inner cover or the outer cover to facilitate bonding of the inner cover to the outer cover.

    摘要翻译： 可径向展开的覆盖支架可预测地且可靠地在相对较低的部署压力下扩张到增加的直径状态，同时最小化扩张期间支架覆盖物撕裂的风险。 支架覆盖物包括通过支架结构并且围绕支架结构粘合在一起以覆盖支架的内盖和外盖。 支架盖由膨胀的聚四氟乙烯（ePTFE）构成，其具有通过纤维互连的节点结构。 当支架处于减小直径，未膨胀状态时，支架覆盖物具有至少约0.008“的径向厚度和至少约100微米的平均间隔距离（IND）。 覆盖的支架以小于或等于约10atm的平均部署压力部署。 根据本发明的覆盖支架结构的方法包括将管状套筒形式的压缩构件放置在外盖上并加热压缩的被覆盖的支架以将内盖结合到外盖。 可以将PTFE的水性分散体形式的粘合剂施加到内盖或外盖上，以便于内盖与外盖接合。
