Patent ID: 8100929

Claim:
A seal assembly for use in a trocar assembly, comprising: a seal body having proximal and distal ends with a longitudinal axis extending therethrough and a transverse plane substantially perpendicular to the longitudinal axis, the seal body having two opposed seal elements extending at an acute angle with respect to the transverse plane, the opposed seal elements having inner and outer surfaces and meeting at a seal face at the distal end of the seal body to define a single opening extending substantially between two points on opposite sides of the seal body and the seal elements being configured to selectively open and substantially close the seal face, wherein the inner surfaces of the seal elements are configured to promote movement of fluid away from a central portion of the seal elements at the seal face at the distal end of the seal body toward a peripheral portion of the seal elements at the seal face at the distal end of the seal body, the peripheral portion being located a distance further from the longitudinal axis than the central portion is from the longitudinal axis.
