Patent ID: 8251955

Claim:
A catheter stylet for stiffening a catheter during a placing process, wherein the stylet comprises a tubular body having a proximal end, a distal end, a lumen for accommodating at least one fluid-guiding line of the catheter and an access for the lumen along which the stylet is configured to be elastically opened laterally to allow for removal of the stylet from around the fluid-guiding line in a direction substantially transverse to a longitudinal axis of the fluid-guiding line, and at least one lever that can be gripped to facilitate opening of the access, the lever having a proximal end and a distal end, the proximal end of the lever being proximate the proximal end of the body, wherein the body has an axial length extending from the distal end of the body to the distal end of the at least one lever that is greater than an axial length of the at least one lever, and wherein the stylet is formed from a film body configured to be altered in its diameter.
