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.
Claims10
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 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, and
- wherein the portion comprises a second lumen of the catheter.

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.

- 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.
