Abstract
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.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
122 words
A trocar support comprising: an elastomeric membrane having an aperture therein for receiving a trocar having an outer surface; said membrane comprising three portions, an elongated wall potion surrounding said aperture, an outer flange portion, and an expandable bellowed intermediate portion therebetween; and 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.
Claim 2
Dependent Claim
122 words
A trocar support comprising: an elastomeric membrane having an aperture therein for receiving a trocar having an outer surface; said membrane comprising three portions, an elongated wall potion surrounding said aperture, an outer flange portion, and an expandable bellowed intermediate portion therebetween; and 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.
Claim 3
Dependent Claim
14 words
A trocar support according to claim 1 wherein said adhesive is a pressure-sensitive adhesive.
Claim 4
Dependent Claim
35 words
A trocar support according to claim 2 further comprising a removable layer of protective material applied to said adhesive that can be removed prior to applying pressure to adhere said membrane to a body surface.
Claim 5
Dependent Claim
30 words
A trocar support according to claim 1 wherein said arc is up to 70 to 80 from the vertical centerline without imposing undue stress which would dislodge the trocar support.
Claim 6
Dependent Claim
46 words
A trocar support according to claim 1 wherein the elongated wall portion is tapered toward the vertical centerline of the aperture to facilitate insertion of the trocar and to provide a tight fit and seal with the outer surface of a trocar to be disposed therein.
