Abstract
A method of accessing a hollow anatomical structure (HAS) of a patient includes puncturing the patient's skin with a needle, upon which is disposed a cannula. A tip portion of the needle is inserted into the HAS. A distal portion of the cannula is advanced distally along the needle, until the distal portion of the cannula is in the HAS. The needle is removed from the HAS while the distal portion of the cannula remains in the HAS. A guide wire is inserted into the HAS via the cannula. The cannula is removed from the HAS while at least a portion of the guide wire remains in the HAS.
