PERCUTANEOUS DILATION APPARATUS

摘要

A percutaneous dilation apparatus is shown. The apparatus is useful for forming and enlarging percutaneous penetrations to a variety of target locations within a patient's body for multiple purposes. The apparatus includes an at least one dilator segment, a dilator probe, and a mechanism for moving each dilator segment along the dilator probe so as to place it within the penetration thereby dilating the penetration.
