Abstract
An access system comprises an access device. The access device is adapted to be disposed within an opening in a body wall. The access device has an external flange adapted to be disposed external to the body wall and an internal flange adapted to be disposed internal to the body wall. Holes extend through the access device between an external surface and an internal surface of the access device. The holes span the thickness of the body wall between a location external to the body wall and a location internal to the body wall. The access device is formed of an elastomeric material adapted to conform to surfaces of instruments inserted through the holes to form instrument seals along at least a portion of a length spanning the thickness of the body wall. The elastomeric material is compressible and adapted to form a seal with the body wall.
