摘要： The present embodiments provide a clip device (20) for engaging tissue. The clip device comprises at least first (21a) and second arms (21b) having proximal (22a, 22b) and distal ends (24a, 24b). The clip device comprises an open state when the spring member (50) is in a compressed state in which the distal end (54) of the spring member is spaced further apart from the distal ends of the first and second arms. In the open state, the distal ends of the first and second arms tend to be spaced apart from each other. Further, the clip device comprises a closed state when the spring member is in a relaxed state in which the spring member is biased to extend distally towards the distal ends of the first and second arms. In the closed state, the distal ends of the first and second arms are adjacent to each other and may engage tissue and promote hemostatis. A delivery system and methods for deploying one or more clip devices also are provided.

摘要： A clip device delivery apparatus for hemostasis has an introducer tube such as an endoscope or sheath having a distal end portion 65 on a distal insertion section 60 and working channel receiving an operating wire detachably securing a clip device 111 comprising tissue engaging arms 127 and a sliding ring for closing the arms. A protective cap 210 having a tube mounting section 220 and a distal section 230 having a receiving chamber 232 define a passageway 240 therebetween, the mounting section being mounted to the introducer tube distal end portion and the distal section receiving tissue and clip arms to close about tissue. The operating wire and clip device are inserted within the working channel. Methods of grasping tissue are provided using the introducer tube introduced endoscopically into a patient, tissue suctioned and clip arms deployed into tissue receiving chamber, sliding ring moved distally to close the clip arms about the tissue, and the clip detached from the operating wire.

摘要： A wire guide torque device (10) includes a handle member (20) having a proximal end and a distal end wherein a groove (29) extends between the proximal end and the distal end of the handle member for inserting a wire guide. A retaining ring (30) is rotatably disposed on the proximal end of the handle member for securing the wire guide inside the groove along the proximal end of the handle member. A lever (40) is slidably disposed in the distal end of the handle member for securing the wire guide inside the groove along the distal end of the handle member. The device further includes a pin (60) having a first end and a second end, wherein the first end is engaged with the lever and the second end is engaged with the handle member.

摘要： Medical devices (11, 51), surgical needle device systems (10), and methods (100) for utilizing an elongate surgical needle (54) that may be used through an endoscope working channel or through an external accessory channel device used with an endoscope are provided. The needle (54) has a proximal end (90) and a flexible distal end (91), an opening (92) at or near the proximal end (90) and an opening (93) at or near the distal end (91), the openings (92, 93) defining a channel (83). The surgical needle distal end (91) comprises a tissue engaging section (94) and an intermediate section (95) being operatively coupled in an axial direction. The tissue engaging section (94) and intermediate section (95) have different flexibility such that the tissue engaging section has greater flexibility than the intermediate section. Optionally, the needle distal end (91) has a preformed bend (97) at or near the tissue engaging section (94), the preformed bend (97) capable of being constrained to a substantially linear configuration and capable of returning to the preformed configuration when unconstrained.

摘要： An apparatus for treating obesity comprises an intragastric member re-configurable from a first configuration to a second configuration, the first configuration being sufficiently small to permit introduction of said intragastric member into a gastric lumen of a mammal, the second configuration being sufficiently large to prevent said intragastric device from passing through the mammal's pylorus. The intragastric member further comprises distal and proximal stoppers and a cinching member, which allow the intragastric member to be held in the first or second configuration.

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.
