Abstract: A surgical access portal includes a seal housing, a sleeve mountable to the seal housing, and a seal disposed within the seal housing. The seal includes a first layer having an opening for the reception and passage of a surgical instrument, a second continuous layer for providing a fluid tight seal in the seal housing in the presence and/or in the absence of a surgical instrument, and a third layer having an opening for the passage of a surgical instrument therethrough. The first and third layers have a higher density than the second layer for maintaining the second layer in an axially compressed state therebetween.

Abstract: The present disclosure relates to a contoured instrument seal for arthroscopic, laparoscopic and endoscopic surgery. The contoured instrument seal includes a body, an annular inner edge, an annular outer edge, and one or more raised concentric rings, e.g., having a spiral shape. The body includes a top surface and a bottom surface. The annular inner edge defines an opening adapted to receive a surgical instrument. The annular outer edge may be adapted to mechanically mount to an inner portion of a seal housing. The raised concentric ring is defined on a surface of the resilient body between the annular inner edge and the annular outer edge.
