摘要： A clip device for hemostasis includes a clip having a proximal end portion and at least two arm portions extending from the proximal end portion and provided with a tendency to open. A sliding ring is provided for closing the arm portions of the clip. A first retainer is attached to the clip, and the first retainer is configured to be releasably secured to a second retainer that may be attached to an operating wire or a torque cable. In operation, the clip device is advanced to a target site in a body cavity. An outer sheath is retracted to expose the clip, causing the arms to open. An inner sheath is advanced distally, causing the sliding ring to advance distally to close the arms of the clip. Stop elements may be disposed on the clip to ensure that he sliding ring is not advanced distally over the clip. Then, the first retainer is disengaged from the second retainer. Various mechanisms are disclosed to permit the first and second retainers to disengage from one another. The first retainer, attached to the clip, is left inside the patient's body cavity, while the second retainer is removed from the patient.
摘要翻译：用于止血的夹子装置包括具有近端部分和从近端部分延伸并且具有打开倾向的至少两个臂部分的夹子。提供一个用于封闭夹子的臂部分的滑动环。第一保持器附接到夹子，并且第一保持器构造成可释放地固定到可附接到操作线或扭矩电缆的第二保持器。在操作中，夹具装置前进到体腔中的目标部位。外护套缩回以露出夹子，导致臂打开。内护套向远侧推进，导致滑环向远侧前进以闭合夹子的臂。止动元件可以设置在夹子上以确保他的滑环在夹子上不向远侧推进。然后，第一保持器与第二保持器脱离接合。公开了允许第一和第二保持器彼此脱离的各种机构。附接到夹子上的第一保持器留在患者的体腔内，而第二个保持器从病人身上取下。

摘要： A clip device (1612) for hemostasis includes a clip having a plurality of arms (1640, 1650) each having a proximal end and a distal end, wherein each of the arms are spaced apart from each other when the clip is in an open position and adjacent to each other when the clip is in a closed position. At least one lumen (1643, 1653) is disposed within a first of the plurality of arms and spans from the proximal end to the distal end of the first arm. At least one outlet bore is formed in the distal end of the first arm. In use, the distal ends of the plurality of arms are adapted to engage tissue in the closed position, and a sclerosing agent is adapted to be delivered to tissue via the lumen and an outlet bore formed in the first arm. Such technique facilitates treatment of the underlying bleeding using a combination of mechanical and sclerotherapy approaches.
摘要翻译：用于止血的夹子装置（1612）包括具有多个臂（1640,1650）的夹子，每个臂具有近端和远端，其中当夹子处于打开位置时，每个臂彼此间隔开并且当夹子处于关闭位置时彼此相邻。至少一个内腔（1643,1653）设置在多个臂中的第一个臂内并且跨越从第一臂的近端到远端。在第一臂的远端形成至少一个出口孔。在使用中，多个臂的远端适于在关闭位置接合组织，并且硬化剂适于经由内腔和形成在第一臂中的出口孔输送到组织。这种技术有助于使用机械和硬化疗法的组合来治疗潜在的出血。

摘要： A two-part extraction balloon and method of use is provided. The balloon catheter comprises a first balloon and a second balloon attached to an elongate catheter shaft near the distal end thereof. The first balloon has an inflated diameter that is larger than the inflated diameter of the second balloon, and in particular has an inflated working diameter range that is greater than the inflated working diameter range of the second balloon. Each of the balloons comprises an elastic or compliant material, and is separately inflatable via one of two inflation lumens extending through the catheter shaft. The larger first balloon is configured to engage and sweep calculi or debris through a relatively large bodily lumen, duct or passageway, whereas the smaller second balloon is configured to engage and sweep calculi or debris through a relatively small bodily lumen, duct or passageway.
