• Attributes: Therapeutic

Intended Use

For use in the endovascular treatment of symptomatic infrainguinal lower extremity vascular disease where total obstructions can not be crossed with standard guide wires.

Device Story

Fiber optic catheter bundle encased in medical grade tubing; delivers 308 nm ultraviolet excimer laser energy to peripheral vascular lesions. Operated by physicians in clinical settings; inserted over guidewires using over-the-wire or rapid exchange techniques. Laser energy photoablates/debulks arterial plaque; enables re-establishment of blood flow and facilitates subsequent vascular interventions. Turbo Plus model features increased 80 Hz pulse repetition rate for faster ablation compared to 40 Hz predecessors. Device benefits patients by clearing total occlusions, allowing for successful endovascular treatment.

Clinical Evidence

Bench testing only. No clinical data presented. Device integrity and functionality were validated using samples produced under routine manufacturing conditions, meeting in-house requirements and ISO 10555-1 standards for sterile, single-use intravascular catheters. Biocompatibility confirmed per ISO 10993.

Technological Characteristics

Fiber optic catheter; 1.4 mm to 2.5 mm tip diameters; 110 cm to 150 cm working lengths. Materials: medical grade tubing, optical fibers. Energy: 308 nm excimer laser (pulsed, 80 Hz). Sterilization: ethylene oxide (ISO 11135). Connectivity: none (standalone).

Indications for Use

Indicated for patients with symptomatic infrainguinal lower extremity vascular disease presenting with total obstructions that cannot be crossed with standard guide wires.

Regulatory Classification

Identification

A percutaneous catheter is a device that is introduced into a vein or artery through the skin using a dilator and a sheath (introducer) or guide wire.

### IDENTIFICATION OF PREDICATE DEVICES

Spectranetics CLiRpath Turbo excimer laser catheters with continuous-on functionality, [510(k) K052296], serve as predicates to the line of CLiRpath Turbo Plus™ excimer laser catheters with 80 Hz and continuous-on capability. The 2.5 mm CLiRpath Turbo excimer laser catheter and CLiRpath™ excimer laser catheters, cleared under 510(k)'s K043465 and K043465, respectively, likewise serves as a predicate devices.

{1}------------------------------------------------

#### DEVICE DESCRIPTION

Spectranetics' CLiRpath excimer laser atherectomy catheters, including CLiRpath Turbo Plus™ models, consist of a bundle of optical fibers, encased within medical grade tubing. The optical fibers conduct ultraviolet laser light (excimer laser light at 308 nm) from a source to the tip of the catheter. The catheter is inserted into a patient's vasculature along the length of a previously inserted guidewire, allowing the operator to deliver laser energy targeted to a lesion (blockage) in the vasculature. CLiRpath laser catheters are provided in models designed for both "over-the-wire" and "rapid exchange" interventional techniques. Laser energy impinged on a blockage photoablales, or debulks, the lesion material re-establishing blood flow within the vessel, and permitting placement of devices used in vascular interventions.

Spectranetics brand CLiRpath Turbo Plus™ excimer laser catheters will add 80 Hz as a maximum repetition rate for pulsed laser energy to the peripheral atherectorny catheter models not already cleared for 80 Hz operation.

#### INTENDED USE

For use in the endovascular treatment of symptomatic infrainguinal lower extremity vascular disease where total obstructions can not be crossed with standard quide wires.

### COMPARISON TO PREDICATE DEVICES

CLiRpath Turbo Plus™ excimer laser catheters for peripheral use are substantially equivalent in form, fit, and function to Spectranelics CLiRpath Turbo excimer laser catheters, including the 2.5 mm Turbo catheter, which has received market clearance under section 510(k) rules. Prior peripheral atherectomy laser catheters with lip sizes ranging from 1.4 to 2.5 mm, delivered photoablating laser energy at up to 40 pulses per second (40 Hz). CLiRpath Turbo Plus™ excimer laser catheters are enhanced versions of these catheters, providing the physician with faster ablation speeds due to a doubled pulse rate of 80 Hz.

CLiRpath Turbo Plus™ excimer laser catheters are fiber optic catheters with a selection of working lengths between 110 cm and 150 cm. Tip diameters range from 1.4 mm to 2.5 mm. The catheters deliver excimer laser energy at 308 nm to an occlusion within a patient's targeted peripheral artery. Delivered energy photoablates occlusive material, such as arterial plaque, and permits its removal via the patient's reticuloendothelial system. The arterial channel opened by either the predicate device or the Turbo catheler, facilitates subsequent placement of other devices and interventions, and reestablishes blood flow within the diseased vessel.

{2}------------------------------------------------

## BIOCOMPATIBILITY, STERILIZATION, PACKAGING, AND BENCH TESTING

CLiRpath Turbo Plus ™ excimer laser catheters are built from the same components and materials of construction as other, already-marketed, Spectranetics products, Therefore, biocompatibility of both component materials and the finished CLiRpath Turbo catheters have been previously confirmed in accord with the ISO 10993 series of standards. Biological Evaluation of Medical Devices. Spectranetics conducts and maintains valid ethylene oxide sterilization processes in accord with ISO 11135, Medical Devices -Validation and Routine Control of Ethylene Oxide Sterilization. Package integrity is initially validated, and, in addition, visually verified for 100% of Spectranetics devices prior to transfer to finished goods inventory.

Device integrity and functionality were qualified and/or validated using samples produced under routine manufacturing conditions. All CLiRpath Turbo Plus™ excimer laser catheter models meet or exceed both Spectranetics in-house requirements, and requirements listed in ISO 10555-1, Sterile, Single-use Intravascular Catheters – Part 1: General Requirements.

#### CONCLUSION

The above statements establish substantial equivalence between the CLiRpath Turbo predicate devices, including 2.5 mm Turbo model, and the CLiRpath Turbo Plus™ excimer laser catheters.
