adhesive material at the flange portion to enable said membrane to adhere to a body surface;
said aperture being sized with respect to the outer surface of a trocar to be disposed therein so as to form a tight fit and seal between the wall portion and the trocar, said intermediate portion being expandable to enable a trocar therein to circumscribe an arc from a vertical centerline without imposing undue stress upon the adhesive surface of the flange portion.

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.
