ABSTRACT:
A surgical snare having a wire which forms the snare loop made from a shape memory effect metallic alloy which exhibits superelasticity at room temperature. The wire is trained so that it assumes an intermediate snare loop size in an unrestrained free state. From this trained free state configuration, the loop can be expanded to a large loop and contracted to a very small loop without permanent deformation from the trained intermediate state. This range of movement enables an expanded range of applicability for snares in general, and also enables reducing the instrument tip size with improved loop configuration.
