Patent ID: 7473220

Claim:
A surgical port device for insertion through a body wall, comprising: a port body including a tubular section having a proximal end opposite a distal end and defining a passageway though which a surgical instrument can be inserted, an exterior surface that extends between said proximal end and said distal end, and a flexible flange disposed at said distal end; a retention member that is slidably mated along and surrounding said tubular section such that a distance between said retention member and said flexible flange can be adjusted, whereby said retention member and said flexible flange cooperate to clamp portions of the body wall disposed therebetween and thus effectively clamp said port body in place; wherein said flexible flange has a frusto-conical shape with a proximally-concave inner surface adapted to engage the body wall opposite a proximally-concave distal outer surface, said flexible flange extending radially outward from the exterior surface of said tubular section in a proximal direction toward the proximal end of said tubular section, and said flexible flange being adapted to fold radially inward such that said inner surface of said flexible flange contacts the exterior surface of said tubular section during insertion of said port body through a narrow opening in the body wall to thereby reduce diameter of the flexible flange during such insertion, and said flange having an annular lip radially spaced from said tubular section that projects outward from a central portion of said distal outer surface to provide a drip edge adapted to direct fluids around its periphery.
