<p>A seal assembly (100) for use with an access device includes a seal housing (102) defining a central longitudinal axis ("b"), an inner wall (112) and an outer wall (114). The inner wall defines a longitudinal opening (116) to permit passage of instrumentation through the seal housing. A gimbal mount (104) is at least partially accommodated within a space (134) defined between the inner wall (112) and the outer wall (114) of the seal housing. The gimbal mount includes a seal member (142) defining an aperture for substantial sealed reception of a surgical instrument. The gimbal mount (104) is adapted for angular movement relative to the central longitudinal axis ("b") upon angulation of the surgical instrument while substantially maintaining the sealed reception of the surgical instrument.</p> |
