## Indications for use
The SherlockTM Tip Location System (TLS) Detector quickly locates and confirms the position of specially designed, magnet-tipped Peripherally-Inserted Central Catheters (PICCs) and Central Venous Catheters (CVCs) during initial placement. This device may be used by appropriate caregivers in hospitals, long-term care facilities or home-care settings. The SherlockTM Tip Location System (TLS) Detector provides rapid feedback to the caregiver, but was not designed to replace conventional methods of placement verification. Users are urged to confirm correct placement according to their established institutional protocol and clinical judgment.
