Abstract
A guard for providing a cut-resistant pathway through a body orifice or incision to circumferentially protect tissue at the margin is provided. The guard is made of flexible, cut-resistant mesh material having a plurality of interwoven thermosetting filaments. The guard has a central lumen and at least one flared end. The flared end, which serves to anchor the guard in the body opening, is deformable into a reduced configuration to facilitate its insertion and removal. The layer of mesh stretches laterally to increase the diameter of the central lumen. The flexibility and expandability of the guard allows the guard to conform to body openings of different sizes. The guard may include a drawstring to cinch the flared distal end from the proximal end. The guard is thermoset with the flared distal end that is biased to spring back to its normal, undeformed configuration when released from a deformed configuration.
