摘要:
The present embodiments provide a tacking device for engaging tissue, which may be useful for coupling a graft member to tissue or facilitating closure of a bodily opening. In one embodiment, the tacking device comprises a main body having proximal and distal ends, a proximal base member disposed at the proximal end of the main body, and at least one tissue engaging member disposed at the distal end of the main body. A spring member is disposed to surround the main body and extends from the proximal base member. In use, the spring member has a relaxed state in which it is biased to extend distally towards the at least one tissue engaging member, and further has a compressed state in which the distal end of the spring member is spaced further apart from the at least one tissue engaging member. Therefore, one or more tissue segments of varying thickness are adapted to be captured between the distal end of the spring member and the at least one tissue engaging member. A delivery system and methods for deploying the tacking device also are provided.
摘要:
The present invention provides a balloon cuff comprising an attachment structure adapted to be disposed around an exterior surface of an endoscope, and a balloon coupled to the attachment structure. An inflation means is in fluid communication with the balloon. The balloon has a deflated state suitable for insertion into a body passage and an inflated state suitable for urging stone fragments along the body passage. Optionally, an intraductal shock wave lithotripsy procedure may be performed through the working lumen of the first endoscope while the balloon cuff is disposed, either inflated or deflated, about the exterior surface of the first endoscope. The first endoscope and balloon cuff may be used alone to remove stone fragments, or alternatively, may be used in conjunction with a second endoscope, such as a duodenoscope, having a working lumen sized to received the first endoscope having the balloon cuff disposed thereon.
