Abstract: A catheter system may include a catheter adapter, which may include a distal end and a proximal end. The catheter system may include a catheter, which may include a distal end, a proximal end, a catheter lumen extending through the distal end of the catheter and the proximal end of the catheter, and an inner surface forming the catheter lumen. The catheter may extend distally from the distal end of the catheter adapter. The distal end of the catheter may include one or more holes. The distal end of the catheter may include one or more channels. The holes and/or the channels may facilitate visualization of blood flashback indicating the catheter is disposed within a vein of a patient.

Abstract: A catheter assembly may include a catheter adapter, which may include a proximal end, a distal end, and a lumen extending between the proximal end and the distal end. The distal end may include a catheter configured to be inserted into vasculature of a patient. The catheter assembly may also include a septum, which may be disposed within the lumen of the catheter adapter. The septum may be secured within the lumen in response to increased pressure by one or more of the following: one or more septum stoppers, a retention disc of a needle assembly, a U-shaped washer, and a conical washer.

Abstract: A catheter assembly may include a catheter adapter. A body of the catheter adapter may include a distal end, a proximal end, and a first lumen extending through the distal end and the proximal end. The catheter adapter may include a side port, which may extend outwardly from the body. The side port may include a second lumen, which may be perpendicular to the first lumen. The catheter assembly may include a catheter extending distally from the distal end of the body. The catheter assembly may include a valve disposed within the first lumen. The valve may include an outer surface that is cylindrical and may seal the first lumen from the second lumen. The catheter assembly may include a divider disposed with the second lumen. The divider may divide the second lumen into a plurality of openings and may increase a burst value of the valve.

Abstract: A catheter system may include a catheter assembly, which may include a catheter adapter and a catheter extending distally from the catheter adapter. The catheter system may include a needle assembly, which may include a needle hub and an introducer needle extending distally from the needle hub. The introducer needle may extend through the catheter. The needle assembly may also include an extension tube, which may include a distal end integrated with the needle hub and a proximal end integrated with a cannula hub. A cannula may extend proximally from the cannula hub. An elastomeric sheath may be coupled to the cannula hub, and a proximal end of the cannula may be enveloped within the elastomeric sheath. In response to the blood collection tube pushing the elastomeric sheath distally, the cannula may pierce the elastomeric sheath, and the cannula may insert into the blood collection tube.

Abstract: A catheter assembly may include a catheter adapter that includes a distal end, a proximal end, and an inner surface forming a lumen. The lumen may extend between the proximal end and the distal end. The catheter assembly may also include a cannula and a cannula hub. The cannula hub may include an outer portion disposed outside of the catheter adapter and an inner portion disposed within the catheter adapter. The cannula may extend distally from the inner portion. In response to the outer portion sliding proximally along an outer surface of the catheter adapter, the cannula may be withdrawn proximally into the catheter adapter. The outer portion may be configured to slide proximally to a locked position in which the cannula hub is locked with respect to the catheter adapter, and a distal tip of the cannula is disposed within the catheter adapter.
