Title:
CLIP SYSTEM AND CLIP
Document Type and Number:
WIPO Patent Application WO/2022/080474
Kind Code:
A8
Abstract:
A clip system for gripping biological tissue of a patient includes a clip having a first arm and second arm closeable by operation of a wire that is reciprocally moveable in a longitudinal channel of a sheath; and a bendable member at a distal end region of the sheath. The bendable member can be an integral portion of the sheath or a separate structure. The bendable member is configured to allow a distal end of a clip to rotate or swing toward a proximal end region of the sheath of the device, which orients the clip relative to the sheath to facilitate grasping of tissue even when the approach of the clip is tangential to the tissue, e.g., at an angle (θ) less than 90. The bendable member can be configured to allow a distal end of a clip to rotate or swing toward a proximal end region of a sheath and form an angle of up to at least about 45 degrees, such up to about 60 degrees or up to about 90 degrees, or higher.
