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： A percutaneous gastrostomy introduction system may include may include an elongate tube assembly including one or both of a dilator portion and a gastrostomy tube portion, which may be continuously formed or joined by one or more connection joints that may—in certain embodiments—provide for rotation about a common longitudinal axis. The dilator portion includes a helical surface for advancing contact with body tissue and may be disposed near (including up to and defining) a first end of the elongate tube assembly. An engagement structure, including—for example—one or more of a wire loop, a user-graspable handle, or another graspable structure may be included at the first end of the device. Device embodiments may be effective to lessen or prevent tenting of patient tissue during introduction.
