Abstract

A surgical port device includes a membrane, a plurality of tubular members traversing the membrane, and means for attaching the membrane to a wall of an organ so that the tubular members traverse a perforation in the wall. A surgical method comprises inserting a distal end portion of a surgical instrument through a natural body opening of a patient into a natural body cavity of the patient, using the surgical instrument to form a temporary artificial opening through a wall of an organ defining the natural body cavity. The port device is inserted through the natural body opening into the natural body cavity, and subsequent to the inserting of the port device, the port device is disposed in the artificial opening to keep the same open.
