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 laser catheter; delivers 308 nm ultraviolet excimer laser energy to peripheral arterial occlusions. Input: laser energy from external source; Output: ablation of lesion material. Used in endovascular procedures by physicians to debulk arterial plaque; re-establishes blood flow; facilitates subsequent vascular interventions. Features 'Turbo' capability allowing continuous laser delivery without programmed on-off sequences required by previous models. Tip diameters 0.9–2.3 mm; working lengths 120–150 cm. Benefits patient by clearing obstructions to restore perfusion.

Clinical Evidence

Bench testing only. Device integrity and functionality were qualified using samples produced under routine manufacturing conditions. Compliance with ISO 10555-1 (Sterile, Single-use Intravascular Catheters) and ISO 10993 (Biocompatibility) was established. No clinical data provided.

Technological Characteristics

Bundle of optical fibers encased in medical grade tubing; 308 nm excimer laser energy source. Tip diameters 0.9–2.3 mm; working lengths 120–150 cm. Over-the-wire and rapid exchange configurations. Sterilization via ethylene oxide (ISO 11135). Materials confirmed per ISO 10993.

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.

Predicate Devices

## IDENTIFICATION OF PREDICATE DEVICES

Spectranetics CLiRpath excimer laser catheters for peripheral use, cleared to market under 510(k) K040067, serve as predicate to the line of CLiRpath excimer laser catheters with Continuous-On capability. The 2.5 mm CLiRpath Turbo excimer laser catheter, cleared under 510(k) K043465, likewise serves as a predicate. _

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

#### DEVICE DESCRIPTION

Spectranetics' CLiRpath excimer laser atherectorny catheters, including CLiRpath Turbo 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 medical guidewire, allowing the attending physician to deliver laser energy targeted to a lesion (blockage) in the blood vessel. CLiRpath laser catheters are provided in models designed for both "over-the-wire" and rapid exchange interventional techniques. Laser energy impinged on a blockage ablates, 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 laser catheters will be supplied in addlional tip diameters between 0.9 and 2.3 mm, appropriate for interventional use in the peripheral vasculature of the leg.

## 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.

## COMPARISON TO PREDICATE DEVICES

CLiRpath Turbo catheters for peripheral use are substantially equivalent in form, fit, and function to other Spectranetics CLiRpath laser catheters, including the 2.5 mm Turbo catheter, which have received market clearance under section 510(k) rules. CLiRpath Turbo catheters form an addition to the CLiRpath product line, providing the medical community with more control over the duration of treatment. Prior models of CLiRpath catheters, excluding the 2.5 mm Turbo model, delivered ablating laser energy for up to 10 seconds, when the activating footswitch was depressed, before electronic controls stopped the system for at least 5 seconds. Only the 2.5 mm Turbo predicate was provided with CLiRpath Turbo capability. Thus successful treatment often required several trains of 10-second laser pulses. The CLiRpath Turbo feature of the new CLiRpath catheter models allows interventions to proceed without the delay in treatment entailed due to a programmed on-off sequence, using catheter tip dimensions over a range from 0.9 mm to 2.3 mm.

CLiRoath Turbo laser products are fiber optic catheters with working lengths to choose from between 120 cm and 150 cm. Tip diameters range from 0.9 mm to 2.3 mm. The catheters deliver excimer laser energy at 308 nm to an occlusion within a patient's targeted perioheral artery. Delivered energy disrupts occlusive material, such as arterial plaque, and permits its removal via the patient's reticuloendothelial system. The pathway opened by either the predicate device or the Turbo catheter, facilitates subsequent placement of other devices and interventions, and re-establishes blood flow within the diseased vessel.

# BIOCOMPATIBILITY, STERILIZATION, PACKAGING, AND BENCH TESTING

CLiRpath Turbo excimer laser catheters are built from the same components and materials of construction as other, already-marketed, Spectranetics products. Therefore, micronal or usinor 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 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 predicate devices, including 2.5 mm Turbo model, and the full line of CLiRpath Turbo excimer laser catheters.
