    摘要： An energy delivery system and a method of delivering energy to a tissue are provided. The energy delivery system includes an overtube. The overtube includes a body having a proximal portion, a distal portion and a lumen extending at least partially therethrough. The proximal portion is adapted to be positioned over a distal portion of an endoscope. The body also includes a first plurality of openings formed in the body and connected to the lumen and an electrode operably connected to the body and extending over at least a portion of a surface of the body. The lumen is operably connectable to a vacuum source and the electrode is operably connectable to a power source.

    摘要： Multi-luminal endoscopic systems for sterilely delivering deployable devices. The system comprises an outer catheter comprising a distal portion and a wall that encloses an outer lumen; an inner catheter movably disposed within the outer lumen and having an inner lumen; a balloon-tipped catheter movably disposed within the inner lumen and having a distal portion and a proximal portion, wherein the distal portion of the balloon-tipped catheter comprises a balloon; a deployable device within the outer lumen; an invertible sleeve within the outer lumen with a first section attached to the distal portion of the outer catheter and a second section attached to a push mechanism that is proximal to the deployable device; and wherein the balloon is expandable to contact the invertible sleeve to provide a seal to prevent bodily fluids from entering the outer lumen.

    摘要： An ablation cap and a method of delivering energy to a tissue are provided. An ablation cap includes a tubular body having a proximal portion, a distal portion, a lumen extending therethrough. The ablation cap also includes a cover portion covering a portion of the tubular body, the covering portion having a region at least partially spaced apart from the tubular body and an electrode portion movably positionable relative to the cover portion. The electrode portion has a covered position where the electrode portion is positioned within the cover portion and an exposed position where the electrode portion is exposed relative to the cover portion. The proximal portion of the body is sized and shaped to fit on a distal end of an endoscope and the distal portion of the body extends distal to the distal end of the endoscope.

    摘要： The present embodiments provide a removable medical device, comprising a sleeve having proximal and distal ends and a lumen extending therebetween. At least one support member having an expanded deployed configuration is coupled to the sleeve using at least one permanent connector. A patch member comprising a resorbable material is coupled to at least a portion of an outer surface of the sleeve using at least one temporary connector. In use, when the support member is in the expanded deployed configuration, at least a portion of the patch member contacts the target site and fluid flows through the lumen of the sleeve. In a separate procedure, a retrieval member is operable to facilitate removal of the sleeve and support member while leaving the patch member disposed within the bodily passageway.
