1. An implantable restraint comprising:
an elongated substrate, disposed along a longitudinal axis, the substrate having a first and second surface disposed along transverse planes, the substrate further comprising:
an opening, extending through the substrate between the first and second surface, configured to receive in-growth of human or animal tissue after implantation such that a tissue anchor may form;
a pair of facing protrusions, disposed between the opening and a distal edge of the substrate, the protrusions being configured to provide an anchor resistance against the tissue anchor to a longitudinal force applied to a proximal section of the substrate;
wherein the pair of protrusions are further configured to separate by a distance approximately equal to a transverse extent of the tissue anchor when the longitudinal force exceeds a first predetermined threshold, such that the pair of protrusions moves past the tissue anchor in the direction of the longitudinal force;
the restraint further comprising:
a contiguous region, disposed between the pair of protrusions and contiguous with the pair of protrusions, the contiguous region configured to provide a separation resistance against an increase in the separation distance of the pair of protrusions;
wherein the region is further configured to rupture when the longitudinal force exceeds a second predetermined threshold, such that a distal opening is disposed between the pair of protrusions.
