First Claim
Patent Images
1. A extension for a catheter assembly, the extension comprising:
- a distal end, comprising a cantilever arm and an insertion feature spaced apart from the cantilever arm, wherein the insertion feature is configured to insert into a lumen of a catheter adapter to provide a fluid connection between the catheter adapter and the extension, wherein the cantilever arm is configured to engage in a snap-fit with the catheter adapter; and
a proximal end comprising a female luer fitting.

Abstract
An extension for a catheter assembly may include a distal end and a proximal end. The distal end may include one or more cantilever arms and an insertion feature spaced apart from the cantilever arms. The insertion feature may be configured to insert into a lumen of a catheter adapter to provide a fluid connection between the catheter adapter and the extension. The one or more cantilever arms may be configured to engage in a snap-fit with the catheter adapter. The proximal end of the extension may include a female luer fitting.

7. A catheter system, comprising:
-
a catheter adapter, comprising a proximal end, a distal end, and a lumen extending therebetween, wherein the proximal end comprises a plurality of slots and a proximal lumen opening, wherein the lumen comprises a septum, wherein the distal end comprises a catheter configured to be inserted into vasculature of a patient, wherein the catheter adapter is configured to be selectively coupled with a distal end of a needle safety feature; an extension, comprising a distal end, a proximal end, and a lumen extending therebetween, wherein the distal end of the extension comprises a cantilever arm and an insertion feature spaced apart from the cantilever arm, wherein the insertion feature is configured to insert into the lumen of the catheter adapter to open the septum and provide a fluid connection between the catheter adapter and the extension, wherein the cantilever arm is configured to insert into the plurality of slots to engage in a snap-fit with the catheter adapter. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14)
