Abstract
Methods and apparatus for percutaneously accessing an implanted port use an access cannula which is periodically introduced to an aperture on the implanted port so that the cannula passes through the same tissue tract. It has been found that repeated passage of the cannula through the same tissue tract reduces patient trauma, with minimized bleeding, 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.
