SYSTEMS AND METHODS FOR PROVIDING A FLUSHABLE CATHETER ASSEMBLY
First Claim
1. A system for controlling fluid flow in a closed IV catheter assembly, comprising:
- a luer port having an inner lumen;
a septum disposed within a portion of the inner lumen; and
a ventilation channel interposed between the septum and an inner surface of the inner lumen of the catheter adapter, the ventilation channel having a surface area and a perimeter selected to permit passage of at least one of air and blood at a desired rate of flow.

Abstract
A flushable catheter assembly having features to enable selective activation of fluid flow through the catheter assembly is disclosed herein. A septum is placed within the catheter adapter of the catheter assembly and includes a pathway that is closed prior to being biased open via a septum activator also positioned within the catheter adapter. A plurality of air vent channels is interposed between the septum and the inner surface of the catheter adapter to permit “flashback” of blood during insertion of the catheter into a patient. The septum activator is advanced through the pathway of the septum as a coupler is attached to a proximal opening of the catheter adapter.

8. A method manufacturing a closed IV catheter assembly having features for controlling fluid flow within the catheter assembly, the method comprising:
-
providing a luer port having an inner lumen; disposing a septum within the inner lumen; and interposedly positioning a ventilation channel between the septum and an inner surface of the inner lumen of the catheter adapter, the ventilation channel having a surface area and a perimeter selected to permit passage of at least one of air and blood at a desired rate of flow. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A closed IV catheter assembly, comprising:
-
a luer port having an inner lumen, the inner lumen having a proximal end, a distal end and a middle portion; a recess forming the middle portion of the inner lumen, the recess being configured to receive a septum, the septum forming a defeatable barrier between the proximal end and the distal end of the inner lumen; a ventilation channel interposed between the septum and an inner surface of the inner lumen of the luer port, the ventilation channel having a surface area and a perimeter selected to permit passage of at least one of air and blood between the proximal end and the distal end of the inner lumen, at a desired rate of flow; a septum activator positioned within the proximal end of the inner lumen, the septum activator having a first end for biasing open a slit of the septum, and a second end having a contact surface; and an opening forming a proximal end of the luer port, wherein an external device is inserted through the opening to contact the contact surface of the septum activator thereby advancing the first end of the septum activator through the slit of the septum. - View Dependent Claims (16, 17, 18, 19, 20)
