摘要： Devices for palliating gastrointestinal strictures using rapid exchange type enteral stent placement catheters. The catheter may include an inner member and an outer member, with the two members being slidable with respect to one another. In various device embodiments, a ramp for directing a guidewire out from within the catheter is provided using portions of the outer member or a shaped mandrel. The inner member may take a number of forms, including a tubular distal portion, a skived or integrally attached elongate midsection, and a proximal portion. A mandrel can be used in a portion proximal of the guidewire ramp, with the mandrel taking one of several disclosed forms.

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。

摘要： An apparatus for moving an object disposed within a body lumen. The apparatus includes a first sheath, a coupling member and at least one contraction member for engaging at least a portion of the object. The coupling member is movable relative to the first sheath between a retracted position and a capture position. In the retracted position, a distal portion of the coupling member is disposed within the first sheath. In the capture position, the coupling member distal portion is disposed outside the first sheath. The coupling member is also selectively attachable to the object in at least the capture position. When the coupling member is attached to the object and the contraction member is directly engaged with the object, a predetermined coupling member movement relative to the contraction member radially contracts at least a portion of the object thereby facilitating movement of the object within the body lumen.

摘要： A tissue clipping apparatus comprises a clip including a proximal end received within a capsule. The clip includes a clip locking member biased to engage a first locking structure of the capsule to lock the clip in the capsule in a closed configuration. The apparatus also comprises a tension member releasably coupling the clip to a proximal end of the device which, during use, remains accessible to a user. The tension member is coupled to the clip by a joint designed to release when subject to a predetermined load to separate the clip from the device, release of the joint releasing the locking member to engage the first locking structure.
