No
The device description and performance studies focus on mechanical properties and biocompatibility, with no mention of AI or ML.
Yes.
The device is intended for the "percutaneous removal of cardiac leads, indwelling catheters and foreign objects," which directly treats a medical condition by removing problematic elements from the body.
No
The device is described as a specialized stylet for the percutaneous removal of cardiac leads, indwelling catheters, and foreign objects. Its function involves providing tractional forces during extraction procedures, which is a therapeutic rather than a diagnostic purpose.
No
The device description clearly details physical components made of stainless steel and Nickel-Chromium, and the performance studies involve mechanical testing of these physical components.
Based on the provided information, the Liberator® Beacon® Tip Locking Stylet is not an IVD (In Vitro Diagnostic) device.
Here's why:
- Intended Use: The intended use clearly states the device is for the percutaneous removal of cardiac leads, indwelling catheters, and foreign objects. This is a surgical/interventional procedure performed on the patient, not a test performed on a sample from the patient to diagnose a condition.
- Device Description: The description details a mechanical device designed to be inserted into a lumen and locked for traction. This is consistent with a surgical tool, not a diagnostic test.
- Lack of IVD Characteristics: There is no mention of analyzing biological samples (blood, urine, tissue, etc.), detecting analytes, or providing diagnostic information about a patient's health status.
- Performance Studies: The performance studies focus on mechanical strength, radiopacity, and biocompatibility, which are relevant for a surgical device, not an IVD.
In summary, the Liberator® Beacon® Tip Locking Stylet is a medical device used in a surgical procedure, not an in vitro diagnostic test.

Device Description
The Liberator® Beacon® Tip Locking Stylet is a specialized stylet that can be inserted through a cardiac lead's inner conductor lumen, once the proximal connector has been removed. The stylet can then be locked into position within the lead's distal portion allowing for the delivery of tractional forces helpful during the extraction procedure.
The Liberator Beacon® Tip Locking Stylet has a braided Nickel-Chromium integral extender (handle). The locking mechanism that is located at the distal end of the stylet is comprised of a uniquely shaped stainless steel wire-locking coil segment attached to a central stainless steel stylet wire. This locking stylet is activated through the forward advancement of a stainless steel cannula that surrounds the central stainless steel stylet wire. Upon activation by the cannula. the wire-locking coil segment at the distal end of the stylet is advanced forward and is compressed. This compression causes the stacking of successive helices of the wire-locking coil. This stacking results in the outward radial displacement of a number of the wire-locking coil's helices against and into the lead conductor coil through which it has been inserted. This outward radial displacement creates the locking engagement of the Liberator® Beacon® Tip Locking Stylet to the lead conductor central or inner lumen. The device is available in a single size compatible with the internal diameter dimensions of many leads and catheters with a central lumen. Stylet wires for checking lead patency are available separately; they consist of a molded plastic handle on a 0.038 cm (0.015 inches) stainless steel wire, with a wire length of 65 cm.
