Catheter Delivery Device to Facilitate Blood Draw

Abstract:

A delivery device for delivering a catheter into an intravenous catheter assembly may include a first catheter, which may include a first portion, a second portion distal to the first portion, and a transition portion disposed between the first portion and the second portion. The first portion may include a first inner diameter along a length of the first portion and a first outer diameter along the length of the first portion. The second portion may include a second inner diameter and a second outer diameter along a length of the second portion. The second inner diameter and the second outer diameter may be less than the first inner diameter and the first outer diameter, respectively. The transition portion may be disposed distal to the distal end of the housing when the first catheter is advanced.
