摘要:
A seal assembly for use in conjunction with a trocar assembly includes a seal body adapted for movement for selectively opening and substantially completely closing the seal assembly. The seal assembly includes a longitudinal axis extending therethrough with a transverse plane substantially perpendicular thereto. The seal body includes a proximal end and a distal end, the proximal end making a first angle with respect to the transverse plane and the distal end making a second angle with respect to the transverse plane, wherein the first angle is less than the second angle.
