Intended Use

The SoundBite® Crossing System - Peripheral (14P) is indicated to facilitate the intraluminal placement of conventional guidewires or treatment devices beyond peripheral artery chronic total occlusions. The SoundBite® Crossing System - Peripheral (14P) is not intended for use in the carotid arteries.

Device Story

The SoundBite Crossing System - Peripheral (14P) is a recanalization tool used by physicians in clinical settings to cross peripheral artery chronic total occlusions (CTOs). The system consists of a reusable mobile console and a single-use sterile titanium alloy active wire (0.014" diameter). The console generates controlled mechanical pulses (shock waves) transmitted along the wire, causing the distal tip to accelerate axially in a reciprocating motion, functioning as a micro-jackhammer. This mechanical action facilitates the advancement of the wire through occlusions, allowing for the subsequent placement of conventional guidewires or treatment devices. The device benefits patients by enabling successful crossing of complex arterial blockages. Physicians operate the system via a footswitch, monitoring the procedure to guide the wire through the vasculature.

Clinical Evidence

Bench testing only. No clinical data. Verification and validation included visual/dimensional inspection, simulated use, coating integrity, tip pull, flexibility, fracture resistance, torque/tensile strength, corrosion resistance, distal temperature, lubricity, and particulate testing. Console testing included output stability, life-cycle, and electrical/software verification per ANSI AAMI ES60601-1 and IEC 60601-1-2. Biocompatibility testing performed per GLP. Summative usability evaluation confirmed safe use without serious errors.

Technological Characteristics

System comprises a mobile AC-powered console and a 300 cm titanium alloy active wire (0.014" diameter). Wire features PTFE coating (excluding distal tip) and a radiopaque marker. Principle of operation is mechanical pulse-driven axial reciprocation. Sterilization via Ethylene Oxide. Software verified per IEC 62304. Electrical safety per ANSI AAMI ES60601-1 and electromagnetic compatibility per IEC 60601-1-2.

Indications for Use

Indicated for patients with peripheral artery chronic total occlusions to facilitate intraluminal placement of guidewires or treatment devices. Not for use in carotid arteries.

Regulatory Classification

Identification

### Device Description:

The SoundBite® Crossing System - Peripheral (14P) is a recanalization tool, designed to help physician's placement of conventional guidewires or treatment devices in the intraluminal space beyond chronic total occlusions in the peripheral vasculature. The SoundBite® Crossing System - Peripheral (14P) consists of the reusable mobile SoundBite® Console, a single-use sterile SoundBite® Active Wire 14P, and their respective accessories.

The SoundBite® Console generates controlled mechanical pulses (i.e., shock waves) which are transmitted to the SoundBite® Active Wire 14P and cause the distal tip of the wire to accelerate axially in a reciprocating motion, acting like a micro-jackhammer.

The SoundBite® Active Wire 14P is similar in construction to the 0.018" CTO crossing wire provided with the predicate device, with a friction reducing PTFE coating (except for the distal tip), a radiopaque marker near the tip, and enhanced flexibility at the distal end. It has an outer

diameter of 0.36 mm (0.014") and it is 300 cm long, with a working length of 145 cm. At the proximal end of the SoundBite® Active Wire 14P, a section reducer allows the wire to be connected to the SoundBite® Console. The single-use SoundBite® Active Wire 14P is supplied sterile with a shelf life of 24 months.
