ANCHORS FOR A COLLAPSING IMPLANT

Anchoring for arms of a suture clip. In some embodiments, an arm-attached anchoring element undergoes a change in shape as it is released from overtube confinement, re-orienting its sharpened tip so that it is prepared for insertion into tissue. The anchoring element may be shaped with recesses and elastic members positioned so that the anchoring element resists deformation strongly once released, but resists less forcefully while held in its confined shape. In some embodiments, an anchoring element is constructed of a first piece, and an arm is constructed as part of a second piece. Arm and anchoring element are assembled, for example, using interlocking shapes cut into each.
