description | Assemblies of guidewires for automatic withdrawal of stylets can include stylet and catheter assemblies. For example, a stylet assembly can include a guidewire disposed in a stylet. The guidewire can include a proximal portion having a first outer diameter, a distal portion including a dilated section having a second outer diameter greater than the first outer diameter, and a guidewire tip in the distal portion of the guidewire. The stylet can include a stylet tip and a stylet lumen therethrough with a stylet inner diameter commensurate with the first outer diameter of the guidewire. At least the proximal portion of the guidewire can be disposed in the stylet lumen of the stylet with a corresponding orientation. The dilated section of the guidewire can be configured to butt against the stylet tip when the guidewire is proximally withdrawn from a catheter for automatic withdrawal of the stylet from the catheter. |
