Patent ID: 8034032

Claim:
A seal assembly for use in conjunction with a trocar assembly, comprising: a seal body extending from a flange member shaped and dimensioned for mounting within the trocar assembly adapted for movement for selectively opening and substantially completely closing the seal assembly, the seal assembly including a longitudinal axis extending therethrough with a transverse plane substantially perpendicular thereto; the seal body including 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; wherein the seal body includes a first section which lies in a first plane at the first angle and a second section which lies in a second plane at the second angle, wherein the first section and the second section extend from the proximal end of the seal body toward the distal end of the seal body and the first section is positioned adjacent the proximal end of the seal body and the second section is positioned adjacent the distal end of the seal body; and wherein the first plane is oriented at approximately a 30 degree angle relative to the transverse plane and the second plane is oriented at between an angle of approximately 40 degrees and approximately 50 degrees relative to the transverse plane.
