description A percutaneous dilational medical insertion device and method comprising a needle removeably disposed in a catheter and a tubular member. The catheter has an inflatable balloon member disposed between a first catheter end and a second catheter end. The second catheter end having a flexible end portion. The needle has a tip that extends beyond the second catheter end that is percutaneously inserted into an interior cavity. After insertion into the interior cavity, the needle is removed from the catheter. When the needle is removed, the flexible end portion of the catheter curls to protect the interior cavity as the catheter is advanced. The catheter is advanced until the inflatable balloon member is received in a wall of the interior cavity. The inflatable balloon member is dilated to form a passageway. The tubular member disposed about the catheter proximate the first catheter end is then advanced into the passageway.
