The description focuses on passive magnetic detection and does not mention any AI/ML components or algorithms.
No
The device aids in catheter placement and tip location confirmation, which is a diagnostic or procedural assistance function, not a therapeutic intervention to treat a disease or condition.
No
The device provides "rapid feedback on catheter tip location" and "quickly locates and confirms the position of specially designed, magnet-tipped Peripherally Inserted Central Catheters (PICCS) and Central Venous Catheters (CVCs)." However, it explicitly states that the device "was not designed to replace conventional methods of placement verification" and that "clinicians are urged to confirm correct catheter placement according to their established institutional protocol and clinical judgment." This indicates that the device assists in placement but does not definitively diagnose the correct placement or a medical condition.
No
The device description explicitly states that the system consists of both a "Sherlock™ TLS Detector" and a "Sherlock™ TLS Stylet," indicating the presence of hardware components.
Based on the provided text, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is to aid in the placement and location of catheters within the patient's body using a magnetic field detection system. This is a procedure performed in vivo (within a living organism).
- Device Description: The device description reinforces that the system is used to guide and locate catheters within the patient's venotomy.
- Lack of IVD Characteristics: The text does not mention any analysis of biological samples (blood, urine, tissue, etc.) or any diagnostic testing performed in vitro (outside of the body).
IVD devices are specifically designed to examine specimens derived from the human body to provide information for diagnostic, monitoring, or compatibility purposes. This device's function is entirely focused on the physical placement and location of a medical device within the body.
N/A
Intended Use / Indications for Use
Catheter stylets provide internal reinforcement to aid in catheter placement. The Sherlock™ TLS Stylet contains passive magnets that generate a magnetic field. This field can be detected by the Sherlock™ TLS Detector to provide the placer rapid feedback on catheter tip location.
The Sherlock™ TLS Detector quickly locates and confirms the position of specially designed. magnet-tipped Peripherally Inserted Central Catheters (PICCS) and Central Venous Catheters (CVCs) during and after initial placement. This device may be used by appropriate caregivers in hospitals, long-term care facilities or home-care settings. The Sherlock™ 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.
