1. An access port assembly comprising:
- an access port comprising a self-sealing access septum and a reservoir; and
a catheter having a proximal end and a distal end opposite to the proximal end, the proximal end of the catheter being fixedly attachable to the access port, the catheter comprising;
a lumen in flow communication with the port when the proximal end of the catheter is attached to the access port,an entry site located between the proximal and distal ends of the catheter, anda portion extending in a distal direction from the entry site toward the distal end of the catheter,wherein the catheter is configured to accept and pass a guidewire directly from an exterior of the catheter to said portion via the entry site,wherein the catheter has an opening at a distal end of the portion, the catheter being configured so that a guidewire passing through the entry site is capable of exiting the catheter via the opening,wherein the lumen is a first lumen of the catheter, andwherein the portion comprises a second lumen of the catheter.

Abstract
An access port assembly having an attachable catheter allows for inserting a guidewire into the catheter to aid in the placement of the integral catheter while still attached to the access port assembly. A method is described for placing an access port fixedly attached to a catheter into a patient using a guidewire inserted into the catheter.

7. A method for inserting an access port assembly into a patient'"'"'s body, comprising:
-
providing a system comprising; a guidewire; and an access port assembly comprising; an access port comprising a self-sealing access septum and a reservoir; and a catheter having a proximal end and a distal end opposite to the proximal end, the proximal end of the catheter being fixedly attachable to the access port, the catheter comprising; a lumen in flow communication with the port when the proximal end of the catheter is attached to the access port, an entry site located between the proximal and distal ends of the catheter, and a portion extending in a distal direction from the entry site toward the distal end of the catheter, wherein the catheter is configured to pass said guidewire directly from an exterior of the catheter to said portion via the entry site; inserting the guidewire into the entry site such that the guidewire extends along said portion of the catheter and through the entry site; inserting the guidewire into the patient'"'"'s body; and manipulating the access port assembly over the inserted guidewire.

8. An access port assembly comprising:
-
an access port comprising a self-sealing access septum and a reservoir; and a catheter having a proximal end and a distal end opposite to the proximal end, the proximal end of the catheter being fixedly attachable to the access port, the catheter comprising a first lumen in flow communication with the port when the proximal end of the catheter is attached to the access port, an entry site located between the proximal and distal ends of the catheter, and a portion extending in a distal direction from the entry site toward the distal end of the catheter, wherein the catheter is configured to accept and pass a guidewire directly from an exterior of the catheter to said portion via the entry site, wherein the portion comprises a second lumen of the catheter, and wherein the second lumen is not in flow communication with the port when the proximal end of the catheter is attached to the access port. - View Dependent Claims (9, 10)
