ENDOSCOPIC COMPRESSION CLIP AND SYSTEM AND METHOD FOR USE THEREOF
First Claim
1. A compression clip assembly for compressing tissue and operable by means of a user-operated applier, said assembly comprising:
- A. an endoscopic compression clip having open and closed positions, wherein said clip includes;
(i) a pair of normally spaced apart elongate members each having an outward-facing surface, and having respective inward-facing opposing surfaces for holding and compressing tissue;
(ii) a hinge formed at least partly of a superelastic material and in operative mechanical connection with said elongate members; and
(iii) a lock region formed on said outer surface of each of said elongate members adjacent to said hinge, each said lock region being delimited by a first stop element proximate to said hinge and a second stop element distal from said hinge; and
B. a lock element for lockably engaging said lock regions so as to lock said clip in its closed position, said lock element and said lock regions being formed so as to facilitate relative translation therebetween until said lock element is positioned between said first and second stop elements.

Abstract
A compression clip assembly for compressing tissue and operable by means of a user-operated applier. The assembly comprises a compression clip and a lock element. The clip includes a pair of normally spaced apart elongate members each having an outward-facing surface, and having respective inward-facing opposing surfaces for compressing tissue; a hinge formed at least partly of a superelastic material and in operative mechanical connection with the elongate members; and a lock region formed on the outer surface of each of the elongate members adjacent to the hinge, each lock region being delimited by a first stop element proximal to the hinge and a second stop element distal from the hinge. The lock element is constructed for lockably engaging the lock regions so as to lock the clip in its closed position. The invention also encompasses a system and method for using the compression clip assembly.

8. A system for applying a compression clip for compressing tissue comprising:
-
A. a compression clip assembly, said assembly including; (a) an endoscopic compression clip having open and closed positions wherein said clip includes; (i) a pair of normally spaced apart, elongate members each having an outward-facing surface, and having respective inward facing opposing surfaces for holding and compressing tissue; (ii) a hinge at least partly formed of a superelastic material and in operative mechanical connection with said elongate members; and (iii) a lock region formed on said outer surface of each of said elongate members adjacent to said hinge, each lock region being delimited by a first stop element proximate to said hinge and a second stop element distal from said hinge; and (b) a lock element lockably engaging said lock regions so as to lock said clip in its closed position, said locking element and said lock regions being formed so as to facilitate relative translation therebetween until said lock element is positioned between said first and second stop elements; B. an applier which includes; (a) a housing having a periphery with a pair of slots symmetrically positioned therein and disengageably mateable with said lock element; (b) a force transmitting element positioned within said housing and including two arms formed of a resilient material, each of said arms having a free end and insertion elements formed thereat for insertion into said hinge; (c) a control means operative to selectably move said force transmitting element in a direction of said first stop elements and in a direction of said second stop elements of said clip; and C. means for applying a resistive force operative to indicate that applying force to overcome the resistive force will lock said clip, wherein said control means may be selectably moved by a user in a selected one of the proximal and distal directions causing said force transmitting element to move by a preselected distance, the distance defined by the encounter of a resistive force when said clip is pulled in the proximal direction, the resistive force provided by the means for applying a resistive force so as to oppose movement of the clip within said lock element, and wherein when said force transmitting element is pulled so as to move said clip beyond the preselected distance overcoming the increased resistive force, said clip is positioned so that said lock element locks said clip in its closed position and said pair of elongate members of said clip are positioned adjacent to each other thereby to compress tissue held therebetween, and said insertion elements pull away and disengage from said hinge and said force transmitting element arms exit said slots. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17, 18)

19. A method for compressing tissue comprising the steps of:
-
bringing a compression clip assembly, including a compression clip and a lock element, using an applier to tissue to be compressed; opening and closing the compression clip, as often as necessary, around the tissue to be compressed until a proper positioning of the clip has been achieved; locking the clip so that its elongate members are held adjacent to each other compressing the tissue held therebetween; and freeing the locked clip from the applier by pulling on a compressed resilient force transmitting element of the applier so that it is brought to, and at least partly passes out of, slots in the wall of a housing of the applier removing the compressive force acting on the resilient force transmitting element allowing for disengagement of the clip from the applier. - View Dependent Claims (20, 21, 22, 23, 24)
