ABSTRACT:
Methods and apparatus for percutaneously accessing an implanted port using an access tube which is periodically introduced to the implanted port. The apparatus is preferably an implantable port having a pressure-responsive valve element. It has been found that repeated passage of the access tube through the same tissue tract to the implantable port reduces patient trauma, with minimized bleeding and reduction in sensitivity. The tract may be initially formed by percutaneously placing a penetrating element through intact skin to the port and leaving the element in place for a time sufficient to created the tract.
