## Abstract

A catheter assembly is disclosed that includes a catheter adapter having a port disposed on its sidewall. A valve is coupled to the port to seal the opening in the port.

## Claims

### Claim 1

A method, comprising:
pressing a button of an intravenous catheter assembly a first time, wherein the intravenous catheter assembly comprises:
a catheter adapter having a sidewall extending between a distal end of the catheter adapter and a proximal end of the catheter adapter, wherein the catheter adapter further comprises an inner lumen extending within the sidewall between the distal end and the proximal end;
an intravenous catheter coupled to the distal end of the catheter adapter, the intravenous catheter having an inner lumen in fluid communication with the inner lumen of the catheter adapter;
a port disposed on the sidewall of the catheter adapter, the port forming an opening between the inner lumen and an external environment such that the port provides direct access to the inner lumen of the catheter adapter;
a septum positioned within the inner lumen of the catheter adapter;
a septum activator positioned within the inner lumen of the catheter adapter, the septum activator configured to be forced through the septum to open a fluid pathway through the inner lumen; and
the button that extends through the port, wherein when the button is pressed the first time the septum activator is forced through the septum, wherein the button is configured to be pressed inwardly towards the inner lumen of the catheter adapter.

### Claim 2 (depends on 1)

The method of claim 1, further comprising pressing the button a second time, wherein when the button is pressed the second time, the septum activator is withdrawn from the septum.

### Claim 3 (depends on 1)

The method of claim of claim 1, wherein the button is coupled with one or more translator elements that translate inward movement of the button to a distal movement of the septum activator.

### Claim 4 (depends on 3)

The method of claim of claim 3, wherein the one or more translator elements are disposed in the inner lumen of the catheter adapter.

### Claim 5 (depends on 1)

The method of claim 1, wherein the button extends through the opening.

### Claim 6 (depends on 1)

The method of claim 1, wherein the button extends through the port perpendicular to a longitudinal axis of the inner lumen of the catheter adapter.

### Claim 7 (depends on 1)

The method of claim 1, wherein the button protrudes from the port to allow a user to press the button.

### Claim 8 (depends on 1)

The method of claim 1, wherein the port includes a first end coupled with the side wall and a second end opposite the first end, wherein the button protrudes from the second end to allow a user to press the button.

### Claim 9

A method, comprising:
pressing a button of an intravenous catheter assembly a first time, wherein the intravenous catheter assembly comprises:
a catheter adapter having a sidewall extending between a distal end and a proximal end and an inner lumen extending within the sidewall between the distal end and the proximal end;
an intravenous catheter coupled to the distal end of the catheter adapter, the intravenous catheter having an inner lumen in fluid communication with the inner lumen of the catheter adapter;
a port disposed on the sidewall of the catheter adapter, the port forming an opening between the inner lumen and an external environment such that the port provides direct access to the inner lumen of the catheter adapter;
a septum positioned within the inner lumen of the catheter adapter;
a septum activator positioned within the inner lumen of the catheter adapter, the septum activator configured to be forced through the septum to open a fluid pathway through the inner lumen; and
the button that extends through the port, wherein when the button is pressed the first time the septum activator is forced through the septum, wherein the button is coupled with one or more translator elements that translate the inward movement of the button to a distal movement of the septum activator.

### Claim 10

The method of claim of 9, wherein the one or more translator elements are disposed in the inner lumen of the catheter adapter.
