ABSTRACT:
A trocar support comprising an elastomeric membrane having an aperture to receive the trocar. The membrane comprises an elongated wall portion which surrounds the aperture and an outer flange portion. Between the flange and the elongated wall is an intermediate, expandable, bellows-like portion which provides flexibility to a trocar inserted through the aperture. Adhesive material is disposed at the flange portion to enable the membrane to be adhered to a body surface. The aperture in the membrane which receives the trocar is sized with respect to the outer surface of the trocar disposed therein, so as to form a substantially tight fit and seal between the wall portion and the trocar.
