Patent ID: 7951118

Claim:
A seal assembly for use with an access device, the seal assembly comprising: a seal housing defining a central longitudinal axis and having proximal and distal ends, the seal housing including an inner wall defining an opening to permit passage of instrumentation through the seal housing; and a gimbal mount disposed within the seal housing, the gimbal mount adapted for angular movement within the seal housing about an axis of rotation, the gimbal mount comprising: a seal defining an aperture for sealed reception of a surgical instrument; and a skirt seal engageable with as peripheral portion of the gimbal mount, the skirt seal being dimensioned to bias the gimbal mount in a proximal direction against an arcuate surface of the seal housing, wherein the skirt seal is adapted to minimize passage of fluids through the seal housing, wherein the skirt seal is positioned about the gimbal mount and arranged to establish a frictional relation between the skirt seal, the gimbal mount and the arcuate surface of the seal housing such that manipulation of the instrumentation will cause the frictional relation to be overcome thereby permitting the gimbal mount to swivel with respect to the seal housing.
