Abstract

See full text

A cannula arrangement includes an inner tube disposed within an outer tube. A flexible sealing element is connected to a proximal portion of the outer tube. The flexible sealing element has a longitudinal axis coaxial with the outer tube. The flexible sealing element has a cantilevered portion that longitudinally extends a longitudinal distance parallel to the longitudinal axis in a proximal direction from the proximal end of the outer tube. The cantilevered portion has a projecting portion that projects diagonally toward the inner tube to define an interior edge to contact an outer surface of the inner tube.
