## Indications for use
Catheter stylets provide internal reinforcement to aid in catheter placement. The SherlockTM TLS Stylet contains passive magnets that generate a magnetic field. This field can be detected by the Sherlock T M TLS Detector to provide the placer rapid feedback on catheter tip location.
