Integrated catheter with independent fluid paths
First Claim
1. A catheter system comprising:
- a catheter adapter comprising;
a catheter hub comprising a distal end and a proximal end and defining a chamber extending between the distal end and the proximal end;
a catheter extending from the distal end of the catheter hub and in fluid communication with the chamber;
a stabilization platform;
a septum disposed within the chamber, wherein the septum comprises a distal wall, a proximal opening, a shoulder disposed between the distal wall and the proximal opening, a first extension extending proximally from the shoulder, and a first lumen extending from the distal wall through the proximal opening; and
a septum canister, comprising a wall, a second extension extending distally from the wall, a third extension extending proximally from the wall, and a wall opening in the wall, wherein the second extension defines a second lumen, wherein the third extension defines a third lumen, wherein the first extension is slidably received within the second lumen, wherein the shoulder abuts the second extension; and
a needle hub comprising;
a needle configured to slidably fit within the catheter, wherein the wall opening is configured to receive the needle;
a needle hub body anchored to a proximal end of the needle,wherein in an insertion configuration, the proximal end of the catheter hub is removably coupled within a distal opening of the needle hub, andwherein after placement of the catheter, the needle hub is retracted from the catheter adapter to slidably remove the needle from the catheter and to separate the needle hub from the catheter adapter.

Abstract
Catheter systems comprising independent fluid paths are disclosed. The catheter systems can include a catheter adapter that has a catheter hub with a chamber. A catheter extends from a distal end of the catheter hub and is in fluid communication with the chamber. A stabilization platform with a first wing and a soft push tab are also part of the catheter hub. The catheter system includes a needle hub with a needle that slidably fits within the catheter. In an insertion configuration, a proximal extension of the catheter hub is removably coupled within a distal opening of the needle hub. After the catheter is placed, the needle hub is retracted from the catheter adapter to slidably remove the needle from the catheter.

8. A method of catheterization comprising:
-
providing a catheter system comprising; a catheter adapter comprising; a catheter hub defining a chamber extending between a distal end and a proximal end; a catheter extending from the distal end of the catheter hub and in fluid communication with the chamber; and a stabilization platform; a septum disposed within the chamber, wherein the septum comprises a distal wall, a proximal opening, a shoulder disposed between the distal wall and the proximal opening, a first extension extending proximally from the shoulder, and a first lumen extending from the distal wall through the proximal opening; and a septum canister, comprising a wall, a second extension extending distally from the wall, a third extension extending proximally from the wall, and a wall opening in the wall, wherein the second extension defines a second lumen, wherein the third extension defines a third lumen, wherein the first extension is slidably received within the second lumen, wherein the shoulder abuts the second extension; and a needle hub comprising a needle configured to slidably fit within the catheter and a needle hub body anchored to a proximal end of the needle, wherein the wall opening is configured to receive the needle; inserting the needle and catheter at a catheter insertion site; advancing the needle and catheter at the catheter insertion site until a primary blood flashback is provided in the chamber of the catheter hub; securing the catheter at the catheter insertion site; and retracting the needle hub from the catheter adapter to slidably remove the needle from the catheter and to separate the needle hub from the catheter adapter. - View Dependent Claims (9, 10, 11)
