Claim 18:
19. A method for accessing and plugging a blood vessel of a subject using a medical device, the medical device including an outer assembly including a first shaft, a first lumen extending through the first shaft, and an atraumatic first tip removably coupled to a distal end of the first shaft and having a first bevel at a distal end thereof, an inner assembly configured to extend through the first lumen of the outer assembly, the inner assembly including a second shaft, a second lumen extending through the second shaft, and a second tip removably coupled to a distal end of the second shaft, the second tip having a second bevel at a distal end thereof, the second bevel being configured to pierce tissue, and a plug assembly configured to extend through the second lumen of the inner assembly, the plug assembly including a third shaft and a plug removably coupled to a distal end of the third shaft, the plug being a solid member without lumens and having a third bevel at a distal end thereof, the method comprising:
piercing a wall of the blood vessel using the bevel of the second tip of the inner assembly of the medical device, thereby forming an opening in the blood vessel and positioning the inner assembly within the blood vessel;
pulling the inner assembly proximally, so that second tip of the inner assembly abuts an inner surface of the wall of the blood vessel;
pushing the outer assembly distally, so that the first tip of the outer assembly comes into contact with skin or an outer surface of the wall of the blood vessel, clamping the skin or the wall of the blood vessel with the second tip of the inner assembly;
engaging the plug of the plug assembly with the second tip of the inner assembly to close the opening in the wall of the blood vessel;
uncoupling the first tip from the first shaft, the second tip from the second shaft, and the plug from the third shaft, thereby plugging the opening of the wall of the blood vessel using the first tip, the second tip, and the plug; and, pulling the first shaft, the second shaft, and the third shaft distally to remove them from the subject.
