    摘要： An expandable probe and a method of delivering energy to a tissue using the expandable probe are provided. The expandable probe includes an elongate shaft having a proximal portion, a distal portion, a lumen extending at least partially therethrough and a longitudinal axis. The expandable probe also includes an arm operably connected to the distal portion. The arm has a first surface including an electrode extending over at least a portion of the first surface and the electrode is operably connectable to an energy source. The arm has a closed configuration and an expanded configuration where the arm in the closed configuration extends substantially parallel to the longitudinal axis and in the expanded configuration the arm extends away from the longitudinal axis.

    摘要： The present embodiments provide a tacking device for engaging tissue, which may be useful for facilitating closure of a bodily opening. The tacking device comprises a main body having proximal and distal ends, and at least one distal deployable member having contracted and expanded states that extends distally from the distal end of the main body. In use, after the distal deployable members have been at least partially expanded at a preliminary location, the distal deployable members may be contracted to permit repositioning at a different, final location. In one exemplary method, at least two tacking devices may be deployed to at least partially surround an opening in tissue, and a suture coupled to the first and second tacking devices may be actuated to facilitate closure of the opening.

    摘要： The present embodiments provide apparatus for facilitating endoscopic resection of tissue. The apparatus comprises proximal and distal barrels. The proximal barrel is adapted to be coupled to an endoscope. A cutting member is disposed within a lumen of the distal barrel and configured to resect a segment of tissue. In one embodiment, a central longitudinal axis of the proximal barrel is radially offset from a central longitudinal axis of the distal barrel, thereby allowing the cutting member to be centered relative to the working lumen of the endoscope. Additionally, the cutting member may comprise at least one viewing window that permits endoscopic visualization of tissue distal to the distal barrel when the cutting member is disposed within the distal barrel.

    摘要： The present embodiments provide apparatus and methods for treating tissue by applying a force to the tissue. In one embodiment, the apparatus comprises a deployable segment having proximal and distal regions, a main body extending therebetween, and a loop member formed at the distal region of the deployable segment. A cannula having a bore is dimensioned to circumferentially surround at least a portion of the main body at a location proximal to the loop member, and a spring member is disposed between the cannula and the loop member. The proximal end of the spring member is affixed to the cannula, and the distal end of the spring member is movable to apply a compressive force to adjust the size of the opening of the loop member and compress tissue disposed within the opening of the loop member. In an alternative embodiment, the cannula is omitted, and a diameter of the loop member is configured to be reduced and increased any number of times before final deployment of the deployable segment.

    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.
