SPRING-BASED DEVICES, SYSTEMS, AND METHODS TO FACILIATE VASCULAR ACCESS

摘要

A catheter system may include a catheter assembly, which may include a catheter adapter. The catheter adapter may include a distal end, a proximal end, and a lumen extending through the distal end of the catheter adapter and the proximal end of the catheter adapter. The catheter assembly may include a catheter, which may extend distally from the distal end of the catheter adapter. The catheter system may include an instrument extending through a distal opening of the catheter. The instrument may include a coil spring.
