Intended Use

The Liberator® Beacon® Tip Locking Stylet is intended for use in patients requiring the percutaneous removal of cardiac leads, indwelling catheters and foreign objects, with a central lumen.

Device Story

Device is a specialized locking stylet for percutaneous extraction of cardiac leads, catheters, and foreign objects. Input: device is inserted into the central lumen of a cardiac lead or catheter. Operation: user removes a latchpin from the tubular handle; pushes the tubular handle forward while holding the integral wire extender stationary; this action advances a stainless steel cannula, compressing a distal wire-locking coil bundle; compression causes outward radial displacement of coil helices, locking the stylet into the lead's inner lumen. Output: mechanical engagement allowing tractional forces for extraction. Used in clinical settings by physicians. Benefits: provides secure grip on indwelling objects to facilitate removal.

Clinical Evidence

Bench testing only. Testing included complete device pull strength, collar tubing/cable integrity, mechanical pull tests in simulated cardiac leads, radiopacity verification, and biocompatibility (ISO 10993-1: cytotoxicity, sensitization, irritation, systemic toxicity, hemolysis, PTT, complement activation, pyrogenicity). Stylet wires underwent pull strength and insertion/retraction cycle testing.

Technological Characteristics

Materials: 304/302 stainless steel, nickel-chromium (handle), platinum-clad tantalum (marker), silver-bearing solder (6% Ag/94% Sn). Principle: Mechanical locking via cannula-actuated radial displacement of a wire bundle. Dimensions: 70 cm working length, 140 cm overall length. Compatibility: .016 to .032 inch operating range. Sterilization: Not specified.

Indications for Use

Indicated for patients requiring percutaneous removal of cardiac leads, indwelling catheters, and foreign objects with a central lumen.

Regulatory Classification

Identification

### Predicate Device:

- Locking Stylet 2 (K970690)
### 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

Below the word "COOK" is the word "MEDICAL" in white, sans-serif font on a red trapezoid. The trapezoid is slightly darker than the rest of the red rectangle.

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.

### Intended Use:

The Liberator® Beacon® Tip Locking Stylet is intended for use in patients requiring the percutaneous removal of cardiac leads, indwelling catheters and foreign objects, with a central lumen.

### Comparison to Predicate:

The subject device is substantially equivalent to the predicate in that it has the same intended use as the predicate. They also have similar technological characteristics, methods of operation, and materials of construction. The substantial equivalence comparison is provided below.
