Abstract
Methods and apparatus for percutaneously accessing an implanted port use a large bore coring needle. The coring needle is periodically introduced to an aperture on the implanted port so that the needle passes through the same tissue tract. It has been found that repeated passage of the needle through the same tissue tract reduces patient trauma, with minimized bleeding, reduction in sensitivity, in contrast to the use of non-coring needles.
