Abstract
A subcutaneous port catheter system includes a reservoir defining a chamber therein. The catheter system also includes a guide catheter attached to the reservoir. The guide catheter has a guide lumen and a distal guide orifice. The catheter system further includes an inner catheter attached to the reservoir. The inner catheter is positioned within the guide lumen and extends through the distal guide orifice. A method of advancing fluid into a blood vessel of a body of a patient is also disclosed.
Claims22
A subcutaneous port catheter system, comprising:
- a reservoir defining a chamber therein;
- a guide catheter having a guide lumen and a distal guide orifice;
- and
- an inner catheter positioned within said guide lumen and extending through said distal guide orifice,
- wherein said reservoir has a first coupling configured to removably connect said guide catheter to said reservoir, and
- wherein said reservoir further has a second coupling configured to removably connect said inner catheter to said reservoir.
A subcutaneous port catheter system, comprising:
- a reservoir defining a chamber therein;
- a guide catheter attached to said reservoir, said guide catheter having a guide lumen and a distal guide orifice;
- and
- an inner catheter attached to said reservoir, said inner catheter being positioned within said guide lumen and extending through said distal guide orifice,
- wherein said reservoir includes an attachment cannula which is in fluid communication with said chamber,
- wherein said attachment cannula includes an increased diameter portion and a reduced diameter portion,
- wherein said guide catheter is attached to said increased diameter portion, and
- wherein said inner catheter is attached to said reduced diameter portion.
A subcutaneous port catheter system, comprising:
- a reservoir having a septum and defining a chamber;
- an inner catheter which is in fluid communication with said chamber;
- and
- a guide catheter having a guide lumen, said inner catheter being at least partially positioned within said guide lumens,
- wherein said reservoir has a first coupling configured to removably connect said guide catheter to said reservoir, and
- wherein said reservoir further has a second coupling configured to removably connect said inner catheter to said reservoir.
A subcutaneous port catheter system, comprising:
- a reservoir having a septum and defining a chamber;
- an inner catheter which is in fluid communication with said chamber;
- and
- a guide catheter having a guide lumen, said inner catheter being at least partially positioned within said guide lumen,
- wherein said reservoir includes an attachment cannula which is in fluid communication with said chamber,
- wherein said attachment cannula includes an increased diameter portion and a reduced diameter portion,
- wherein said guide catheter is attached to said increased diameter portion, and
- wherein said inner catheter is attached to said reduced diameter portion.
