Abstract
Abstract A cannula for insertion into a body incision is provided with a tip (54) having an opening (65) in the sidewall and a pair of recesses (82, 84) in the outer surface of the tip defining a longitudinally extending ridge (80). The ridge (80) facilitates insertion of the tip (54) by gradually dilating the incision.
