<p>A surgical fastening clip (1) of a shape memory alloy which applies a first clamping force to a site when the alloy is in its martensitic condition and a second clamping force to the site when the alloy heats due to surrounding tissue such that the alloy transforms to its austenitic condition. The second clamping force is greater than the first clamping force and prevents the clip from slipping or falling off the clamped site due to shrinkage or movement of the site. A method of using a surgical fastening clip of the invention and methods of making such clips formed of a shape memory alloy are also disclosed.</p> |
