Surgical clip
First Claim
1. A surgical clip having a sliding state and a crimped state, and being adapted for use in a surgical procedure initially to slide along suture ends to an operative position and ultimately to crimp the suture ends at the operative position, comprising:
- a substrate bendable between the sliding state and the crimped state, the substrate being formed from a material having a first coefficient of friction with the suture ends;
a first coating carried by the substrate to form a layer of material on the substrate;
the material of the layer forming a barrier between the suture ends and the substrate, the barrier being adapted to inhibit contact between the suture ends and the substrate when the clip is operatively dropped on the suture ends;
the material of the first layer having properties for engaging the suture ends with a second coefficient of friction less than the first coefficient of friction to facilitate sliding of the clip on the suture ends;
a second coating carried by the substrate and forming a second layer of a second material; and
the second material having properties including a third coefficient of friction with the structure ends, the third coefficient of friction being greater than the first coefficient of friction to faciliate traction between the suture ends and the clip in the crimped state.

Abstract
A surgical clip having a sliding state and a crimped state is adapted for use in a surgical procedure initially to slide along suture ends to an operative position and ultimately to crimp the suture ends at the operative position. A substrate, bendable between the sliding state and the crimped state carries at least one coating having either lubricious or traction enhancing properties. A second coating can be added to form a coating laminate with the outer coating having lubricious properties facilitating the sliding state and the inner coating having traction enhancing properties facilitating thee crimped state.
