Abstract
A dilator assembly for forming and enlarging percutaneous penetrations into body cavities includes an elongate guide member and one or more elongate dilation members. The guide member includes a retractable anchor near its distal end so that an outward force or tension may be maintained on the body cavity wall as successfully larger dilators are introduced over the guide member. In this way, the alignment of the guide member is maintained along the initial penetration and the tendency for the wall of the body cavity to separate from and invaginate into the surrounding fascia is reduced. Alternatively, means may be provided for internally tensioning or stiffening the guide member so that the guide member will remain aligned and resist withdrawal, buckling, and kinking as a dilator or working catheter is introduced.
