PORTED IV CATHETER HAVING EXTERNAL NEEDLE SHIELD AND INTERNAL BLOOD CONTROL SEPTUM
First Claim
1. An extravascular system for accessing the vasculature of a patient, comprising:
- a catheter adapter having a distal end supporting a catheter, and further comprising a proximal opening, the catheter adapter having a lumen;
an access port coupled to an outer surface of the catheter adapter and having an inner lumen that is in fluid communication with the lumen of the catheter adapter;
a blood control septum disposed within the lumen of the catheter adapter and dividing the lumen into a proximal fluid chamber and a distal fluid chamber;
a defeatable barrier disposed within the lumen of the catheter adapter and forming a sealed interface with the inner lumen of the access port;
a septum activator slidably positioned within the proximal fluid chamber, the septum activator having a base and a probe end; and
an external safety mechanism removably coupled to the proximal opening of the catheter adapter and comprising a safety clip configured to secure a sharpened tip of an introducer needle.

Abstract
An extravascular system is provided which includes a catheter adapter having a blood control septum configured to control flow of a fluid through the catheter adapter, the catheter adapter further having a catheter configured for intravenous insertion. The extravascular system further includes a septum activator slidably inserted within the catheter adapter and configured for advancement through the blood control septum to provide a fluid pathway through the blood control septum. Further still, the extravascular system includes an external safety mechanism comprising a needle hub and a needle shield interconnected via a tether, wherein the needle shield includes a safety clip that is configured to retain a sharpened end of the introducer needle within the needle shield. Some implementations further comprise an access port forming a portion of the catheter adapter and providing selective access to the lumen of the catheter adapter.

9. A method for manufacturing an extravascular system for accessing the vasculature of a patient, the method comprising steps for:
-
providing a catheter adapter having a distal end supporting a catheter, the catheter adapter further comprising a proximal opening and a lumen interposed between the proximal opening and the catheter; coupling an access port to an outer surface of the catheter adapter, the access port having an inner lumen in fluid communication with the lumen of the catheter adapter; disposing a blood control septum within the lumen of the catheter adapter and dividing the lumen into a proximal fluid chamber and a distal fluid chamber; disposing a defeatable barrier within the lumen of the catheter adapter and forming a sealed interface with the inner lumen of the access port; slidably inserting a septum activator within the proximal fluid chamber, the septum activator having a base and a probe end; and coupling an external safety mechanism to the proximal opening of the catheter adapter, the external safety mechanism having a safety clip configured to secure a sharpened tip of an introducer needle. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18)

19. An extravascular system for accessing the vasculature of a patient, comprising:
-
a catheter adapter having a distal end supporting a catheter, and further comprising a proximal opening, the catheter adapter having a lumen; an access port coupled to an outer surface of the catheter adapter and having an inner lumen that is in fluid communication with the lumen of the catheter adapter; a blood control septum disposed within the lumen of the catheter adapter and dividing the lumen into a proximal fluid chamber and a distal fluid chamber; a defeatable barrier disposed within the lumen of the catheter adapter and forming a sealed interface with the inner lumen of the access port; a septum activator slidably positioned within the proximal fluid chamber, the septum activator having a base and a probe end; an external safety mechanism removably coupled to the proximal opening of the catheter adapter and comprising a safety clip configured to secure a sharpened tip of an introducer needle, the introducer needle further comprising a base supported by a needle hub and having a body extending between the base and the sharpened tip, the body of the introducer needle being inserted through the external safety mechanism, the lumen of the catheter adapter and the catheter such that the sharpened tip of the introducer needle is positioned external to a tip of the catheter prior to insertion of the catheter into the vasculature of the patient; and a pawl forming a portion of the safety clip and positioned within a proximal rim of the catheter adapter to maintain an interlocked connection between the external safety mechanism and the catheter adapter, wherein upon removal of the introducer needle from the external safety mechanism the safety clip is released and the pawl is disengaged from the proximal rim, thereby disconnecting the external safety mechanism from the catheter adapter. - View Dependent Claims (20)
