Abstract: A passive safety catheter assembly configured to inhibit access to the distal tip of a needle cannula prior to release of a catheter insertion assembly from a catheter hub. The passive safety catheter assembly includes a safety clip assembly configured to transition between a first position in which the safety clip assembly selectively couples the catheter insertion assembly to the catheter hub, and a second position in which the safety clip assembly traps the sharp distal tip of the needle cannula within the safety clip assembly prior to release of the coupling between the catheter insertion assembly and the catheter hub.

Abstract: A catheter hub assembly. The catheter hub assembly includes a catheter hub body, a septum and a septum retainer, the catheter hub body having a distal end, a proximal and an internal wall defining an internal fluid passageway therebetween, the internal wall defining a transitional step within the internal fluid passageway, the septum positioned within the internal fluid passageway such that a distal end of the septum abuts up against the transitional step, the septum retainer at least partially receivable within the internal fluid passageway and having an outer wall shaped and sized to interlock with the inner wall of the catheter hub body, the outer wall including one or more lateral ribs configured to inhibit rotation of the septum retainer relative to the catheter hub body.

Abstract: A needle assembly for sampling fluid from a patient including a needle guard, an insertion needle, and a needle housing. The distal end of the needle guard includes a nose portion and a flexible nose extension defining a fluid collection reservoir. The proximal end of the needle guard includes a push feature. The insertion needle has a sharpened distal tip, a proximal needle end and a shaft defining a lumen extending therebetween. The needle housing is operably coupled to the proximal needle end and is slideably coupled to the needle guard. The needle housing includes a flash chamber including a wall defining a cavity. The cavity is in fluid communication with the lumen of the insertion needle and is sealed at one end by a gas permeable flash plug. The push feature selectively engages the flash plug to divert captured bodily fluids to the fluid collection reservoir for sampling.

Abstract: Catheter assemblies may include introducer needles having a notch or similar structure that allows flashback blood to enter the annular space between a catheter tube and an introducer needle of an IV catheter. The presence of flashback blood in this annular space can provide a clinician with an early, visible indication that a needle has entered a vein. The notch, however, may create a leak path for blood to escape outside of the catheter assembly, unless contained. Disclosed herein is a notch containment that prevents the notch from providing a leak path for blood to escape outside of the catheter during or after needle withdrawal.

Abstract: A method of constructing a catheter assembly having an integrated septum. The method comprising molding a catheter hub having a distal end, a proximal end, and an internal wall defining an internal fluid passageway therebetween, the internal fluid wall defining an injection mold window located between the distal end and the proximal end; seating a catheter tube within the internal fluid passageway of the catheter hub, such that a proximal end of the catheter tube resides within the internal fluid passageway of the catheter hub, and a distal end of the catheter tube extends distally from the distal end of the catheter hub; plugging at least a proximal end of the catheter hub with a mold core shut off pin; and injection molding a septum in at least a portion of the internal fluid passageway between the mold core shut off pin and the proximal end of the catheter tube through the injection mold window.

Abstract: A safety catheter insertion device configured to automatically retract a needle cannula following insertion of a catheter assembly and to inhibit release of the catheter assembly from the safety catheter insertion device until the needle cannula has been retracted for the purpose of inhibiting inadvertent needle sticks. The safety catheter insertion device including an advancement arm slidably coupled to a needle housing assembly and configured to shift between a first position in which a needle cannula traverses through a catheter hub coupling portion of the advancement arm to inhibit release of a catheter assembly, and a second position in which one or more tabs of the advancement arm interact with one or more retention arms of the needle housing assembly to enable a biasing mechanism to shift the needle assembly to a proximal position and enable release of the catheter assembly from the safety catheter insertion device.

Abstract: The present disclosure provides for a safety catheter assembly comprising a needle hub, a catheter hub, a tip protector housing.
