Abstract
Embodiments of the invention provide a surgical snare structure in which the material used for the snare and the deployment mechanism of the snare are configured to improve the cutting efficacy of the snare. In particular, the surgical snare structure of the invention may omit the kink or nib present in the loop of known surgical snares and/or may provide a reaction surface against which the cutting action of the snare is effective. The surgical snare of the invention may be a cold, i.e. mechanical-only effect, snare, or may be used in conjunction with radiofrequency (RF) and/or microwave energy to enhance a cutting or coagulation effect.
