TUBULAR INSTRUMENT TO REDUCE VEIN TRAUMA AND RELATED DEVICES AND METHODS

Abstract:

A delivery device to deliver a tubular instrument into a catheter extending distally from a catheter adapter. The delivery device may include a housing configured to couple to the catheter adapter. The delivery device may include a tubular instrument configured to insert through the catheter. The tubular instrument may include a distal end, a proximal end, and a lumen extending between the distal end and the proximal end. The distal end may include a distal tip, which may be closed. The proximal end may be secured within the housing. The tubular instrument may be configured to advance distally with respect to the housing. A portion of the distal end proximate the distal tip may include a first material and may be stiffer than the distal tip, which may include a second material. A durometer of the first material may be greater than a durometer of the second material.
