Abstract:
1. An introducer for introducing a medical device into a vasculature of a patient, comprising: a sheath defining a proximal end, an open distal end, and a central bore extending therebetween, a distal region of the sheath including at least one curved outer surface portion proximally extending from the distal end thereof, a cross section of the at least one curved outer surface portion at least partially defined by a first radius; and a dilator that is removably received within the central bore of the sheath such that at least a portion of a distal tapered region of the dilator extends proximally into the central bore of the sheath when the dilator and sheath are mated wherein the sheath further includes a second curved outer surface portion cross sectionally defined by second radius, and wherein the at least one curved outer surface portion and the second curved outer surface portion provide a bullet-shape cross sectional profile to the distal end of the sheath.
