ABSTRACT:
An endoscopic retractor is an elongate balloon having an expanded configuration having two end portions and a plurality of struts or spacer members extending between the end portions. The retractor balloon is a single tubular preform bent during manufacture to form the expanded configuration. Thus, the struts or spacer members are integral with both end portions and define therewith a single flow path for inflation or pressurization fluid.
