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.

11. The access port according to claim 10, wherein a reservoir is formed between the self-sealing access septum and the lower body and said catheter is in flow communication with the reservoir through said outlet.

12. The access port according to claim 10, wherein the upper body has an access site disposed therein.

13. An access port device comprising:

a body having a self-sealing first access septum disposed in a top portion of the body;

a self-sealing second septum disposed in the body for inserting a guidewire through the body and into the outlet.

14. The access port according to claim 13, wherein a reservoir is formed in the body and is in flow communication with the catheter through the outlet.

15. The access port according to claim 14, wherein the outlet has an axis therethrough and the second septum is disposed opposite the outlet alone the outlet axis.

16. The access port according to claim 13, wherein the catheter includes a reinforced portion adjacent the access port.

17. The access port according to claim 13, wherein the body portion is made of one of titanium, acetal, and polysulfone and the septums are made of silicone.

18. An access port assembly comprising:

an access port having a self-sealing access septum;

a catheter fixedly attachable to the access port, the catheter having a first lumen in flow communication with the port when attached to the access port and a second lumen having an entry site adapted to accept a guidewire into the second iumen.

19. The access port according to claim 18, wherein said entry site is an opening intermediate the access port and a distal end of the catheter.

20. The access port according to claim 18, wherein the catheter includes a reinforced portion adjacent the access port.

21. The access port according to claim 18, wherein said entry site is a slit in the catheter, the slit extending substantially the length of the catheter.

22. The access port according to claim 18, wherein the slit has a width smaller than the guidewire.

23. An access port comprising:

an access port body including a reservoir;

an outlet in flow communication with the reservoir for attaching the access port body to a catheter;

a rigid insert positioned in the bottom portion of the reservoir.

24. The access port according to claim 23, wherein the rigid insert extends into the outlet.

25. The access port according to claim 23, wherein the reservoir has a periphery and the rigid insert extends upward around the periphery.

26. The access port according to claim 23, wherein the rigid insert includes an opening in the upward extension allowing a guidewire to be passed therethrough.

27. The access port according to claim 23, wherein the rigid insert has an narrowing area adjacent the outlet.

28. An access port device comprising:

a body having a self-sealing first access septum disposed in a top portion of the body;

an outlet disposed in the body for fixedly attaching a catheter; and

a self-sealing second septum disposed in the body for inserting a guidewire through the body and outlet and into the catheter when attached to the access port.

29. The access port according to claim 28, wherein a reservoir is formed in the body and is in flow communication with the catheter through the outlet.

30. The access port according to claim 28, wherein the outlet has an axis therethrough and the second septum is disposed opposite the outlet along the outlet axis.

31. A method for inserting an access port fixedly attached to a catheter into a body comprising the steps of:

inserting the guidewire into the body;

manipulating the catheter and access port over the guidewire to place the distal end of the catheter at the desired location;

removing the guidewire from the patient and access port; and

inserting and securing the access port in the body.

32. A method for inserting an access port fixedly attached to a catheter into a body comprising the steps of:

inserting a guidewire into the body;

inserting a proximal end of the guidewire into a means for directing the guidewire into the catheter while the guidewire is in the body;

manipulating the catheter and access port over the guidewire to place the distal end of the catheter at the desired location;
