摘要： Medical devices and related methods are provided for treating a bleeding side of an internal bodily organ that are robust and versatile for use in a variety of endoscope applications. One embodiment of a medical device includes a catheter, a sheet and elongated forceps. The catheter defines a catheter lumen and is sized to be received within the accessory channel of the endoscope. The sheet is formed of hemostatic fabric formed into a tubular configuration having opposing first and second ends. The elongated forceps have a pair of collapsible grasping jaws. The grasping jaws are collapsed around the first end of the sheet, and the grasping jaws and sheet are received within the catheter lumen.

摘要： The present embodiments provide systems and methods for repairing tissue using one or more tacking devices. In one embodiment, the system comprises a graft member and at least one protective member configured to enclose at least a portion of a tacking device. The protective member may include, without limitation, a pocket having an enclosure forming an interior space, a plug of material or a barrier layer. When at least one tacking device is deployed to couple the graft member to the tissue, at least a portion of the tacking device is enclosed by the protective member to reduce the exposure of the tacking device.

摘要： The present embodiments provide apparatus and methods suitable for containing and delivering a therapeutic agent to a target site. The apparatus generally comprises at least one container for holding a therapeutic agent, and a pressure source for facilitating delivery of the therapeutic agent. In one embodiment, the pressure source may be placed in selective fluid communication with a proximal region of the container and fluid from the pressure source may flow through at least a portion of the container to urge the therapeutic agent through the container towards the target site. In an alternative embodiment, the pressure source may be selectively in fluid communication with either a first hollow tube and the container so that therapeutic agent is urged into a catheter, or with a second hollow tube and a catheter so that a fluid from the pressure source bypasses the container and enters the catheter.

摘要： A method and device for incising tissue within the gastrointestinal tract is described. The device is an electrosurgical sphincterotome cutting device. The sphinctertome includes a pre-curved, heat set FEP distal tip. An electrically conductive cutting wire is positioned along the pre-curved distal tip. Manipulating a control handle tightens the cutting wire and incises and cauterizes target tissue. The curvature of the distal tip allows the sphincterotome to orient and steer itself towards a patient's sphincter as it emerges from an accessory channel of an endoscope.

摘要： Described herein are a system and a method for forming a stent of a desired length endoluminally. The system includes an elongate stent body and an outer sheath overlying the stent body. An endoluminal cutting mechanism is operatively connected to a drive cable in communication with the outer sheath. The cutting mechanism is configured to cut the stent body in response to motion of the drive cable. The method of forming the stent of a desired length endoluminally includes directing a system including an elongate stent body and an outer sheath overlying the stent body into a body lumen, positioning the stent body at an endoluminal site, and severing the stent body to form a stent of a desired length at the endoluminal site. An undeployed portion of the stent body remains in the outer sheath for optional deployment in a subsequent severing operation.
