Expanding surgical access port
First Claim
Patent Images
1. A surgical access port, comprising:
- a cylindrical member having a proximal end and a distal end and defining a longitudinal axis;
at least two lumens extending through the cylindrical member along the longitudinal axis;
at least one internal cavity defined in the cylindrical member, the entire lumen of each of the at least two lumens positioned radially outward of at least a portion of the at least one internal cavity with respect to the longitudinal axis, the at least one internal cavity enclosed by the proximal and distal ends of the cylindrical member; and
a source of inflation fluid coupled to the at least one internal cavity, the source of inflation fluid configured to permit selectable inflation of the at least one internal cavity, whereby inflation of the at least one internal cavity increases a radial distance between the at least two lumens.

Abstract
A surgical access port that includes a cylindrical member having a proximal end and a distal end and defining a longitudinal axis; at least two lumen extending through the cylindrical member along the longitudinal axis; at least one cavity defined in the cylindrical member and positioned radially within the at least two lumen; and a source of inflation fluid coupled to the at least one cavity, the source of inflation configured to permit selectable inflation of the at least one cavity, whereby inflation of the at least one cavity increases the radial distance between the at least two lumen.
