Claim Text:
1. A surgical access port system adapted for performing laparoscopic surgical procedures at a natural orifice comprising: an outer ring, wherein the outer ring is configured to be disposed proximate the natural orifice of the patient and substantially surround the orifice; a tubular body having a proximal end, a distal end, a longitudinal axis and a fixed length and diameter adapted to accommodate the anatomy of the natural orifice, wherein the tubular body defines a generally cylindrical passage large enough to accommodate at least two laparoscopic instruments there through; a funnel segment extending between and coupling the outer ring and the proximal end of the tubular body, wherein the funnel segment provides a diametric reduction between the relatively large diameter of the outer ring and the relatively smaller diameter of the tubular body, which is sized to fit within a natural orifice with minimal distention of the orifice; a removable gel cap, wherein the gel cap comprises a gel pad and a cap ring coupled with the gel pad, wherein the cap ring is engagable with the outer ring; a trocar comprising a tubular cannula body having a proximal end, a distal end, a longitudinal axis extending from the proximal end to the distal end, and a cannula wall defining a cannula lumen, a seal assembly coupled to the proximal end of the cannula body, and a retainer extending from the distal end of the cannula body, wherein the tubular cannula body is disposed through the gel pad at a site selected by the user to capture the gel pad between the retainer and the seal assembly; an inflation port disposed within the funnel segment; an inflatable member circumferentially disposed around the distal end of the tubular body; and a channel connecting the inflatable member to the inflation port; wherein the inflatable member is configured upon to expand upon inflation circumferentially outward from the distal end of tubular body to engage the wall of the natural orifice and to thereby secure the tubular body within the natural orifice.
