Abstract:
1. A system for deploying at least one clip device, the system comprising: a first clip device having first and second arms, wherein distal ends of the first and second arms tend to be spaced apart from each other when the first clip device is in an open state, and wherein the distal ends of the first and second arms are adjacent to each other when the first clip device is in a closed state; a sliding ring being movable between a first position when the first clip device is in the open state and a second position to hold the first and second arms of the first clip device in the closed state; an inner catheter having a lumen, wherein the first clip device and the sliding ring are configured to be selectively advanced through the lumen of the inner catheter; and an outer catheter having a lumen, wherein the inner catheter is configured for longitudinal movement with respect to the lumen of the outer catheter, wherein selective positioning of the outer catheter over a distal region of the inner catheter causes the distal region of the inner catheter to bow radially inward to form a constriction that selectively engages the sliding ring of the first clip device using a friction fit, so that the sliding ring does not move either proximally or distally.
