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.

First claim

1 . A catheter assembly, comprising:
a catheter adapter having a distal end and a proximal end and an inner lumen extending between the distal end and the proximal end; a port disposed on a sidewall of the catheter adapter, wherein the port forms an opening between the inner lumen and an external environment; a housing coupled to the port; and a septum coupled to the port and disposed within the housing, wherein the septum seals the opening of the port.

2 . The catheter assembly of claim 1 , wherein the catheter adapter further comprises a catheter coupled to the distal end of the catheter adapter.

3 . The catheter assembly of claim 1 , wherein the catheter adapter further comprises a septum activator disposed within the inner lumen.

4 . The catheter assembly of claim 1 , wherein the port is disposed at an angle of between about 15° and about 90° relative to the longitudinal axis of the catheter adapter.

5 . The catheter assembly of claim 1 , wherein the housing is directly coupled to the port.

6 . The catheter assembly of claim 5 , wherein the housing is directly coupled to the port via one or more threads disposed on the port.

7 . The catheter assembly of claim 1 , wherein the housing is a top housing, further comprising a bottom housing, wherein the top housing is coupled to the bottom housing, wherein the bottom housing is directly coupled to the port.

8 . The catheter assembly of claim 7 , wherein the bottom housing is directly coupled to the port via one or more threads disposed on the port.

9 . The catheter assembly of claim 7 , wherein a bottom portion of the septum is disposed between the top housing and the bottom housing.

10 . A catheter assembly, comprising:
a catheter adapter having a distal end and a proximal end and an inner lumen extending between the distal end and the proximal end; a port disposed on a sidewall of the catheter adapter, the port forming an opening between the inner lumen and an external environment; a ball valve coupled to the port and sealing the opening of the port, wherein the ball valve comprises a spherical member having a hole extending therethrough, wherein when the hole is in line with a central axis of the port, the ball valve is open; and a septum disposed within the inner lumen at a location proximal the port.

11 . The catheter assembly of claim 10 , further comprising an actuator coupled to the ball valve, wherein the actuator is configured to turn the spherical member such that the hole is perpendicular to the central axis of the port and such that the ball valve is closed.

12 . The catheter assembly of claim 10 , wherein the catheter adapter further comprises a catheter coupled to the distal end of the catheter adapter.

13 . The catheter assembly of claim 10 , wherein the catheter adapter further comprises a septum activator disposed within the inner lumen.

14 . The catheter assembly of claim 10 , wherein the port is disposed at an angle of between about 15° and about 90° relative to the longitudinal axis of the catheter adapter.

15 . The catheter assembly of claim 10 , further comprising a cap removably coupled to the port.
