摘要:
The present embodiments provide systems and methods for deploying at least one clip device. In a first embodiment, the system comprises a first clip device having first and second arms. The first clip device and an associated sliding ring are configured to be selectively advanced through a lumen of an inner catheter. Selective positioning of an outer catheter over a distal region of the inner catheter causes a distal region of the inner catheter to bow radially inward to form a constriction that securely engages the sliding ring of the first clip device, thereby allowing for partial closure and repositioning of the first clip device. In an alternative embodiment, a delivery system includes a single catheter having a tapered distal region, such that upon ejection of the sliding ring from the distal end of the catheter, the sliding ring is dimensioned to abut the distal end of the catheter. In any of the embodiments, multiple clips may be sequentially loaded and deployed using the delivery systems. Various clip designs and a loading cylinder are also disclosed.
