Intended Use

CLiRpath™ catheters are intended for use in ablating a channel in totally occlusive peripheral vascular disease (including the superficial femoral, popliteal and infrapopliteal arteries), for enhancing the potential for limb preservation.

Device Story

CLiRpath Excimer Laser Catheter consists of optical fiber bundle encased in medical-grade tubing; delivers 308 nm ultraviolet excimer laser energy to lesion sites. Used in peripheral arteries (superficial femoral, popliteal, infrapopliteal) to ablate/debulk arterial plaque in total occlusions. Operated by physicians in clinical settings; catheter tracks over previously inserted guidewires. Available in over-the-wire and rapid-exchange configurations; tip diameters 0.9 mm to 2.5 mm. Laser energy disrupts occlusive material, creating a channel to restore blood flow and facilitate subsequent vascular interventions. Benefits include limb preservation and successful crossing of lesions resistant to conventional guidewires.

Clinical Evidence

Prospective clinical study of 47 patients with distal peripheral arterial disease. Primary endpoints: lesion crossing success and procedural success. Results: 79% of lesions crossed successfully; 72% overall procedural success; 79% straight-line blood flow re-established to the foot. Serious adverse events were reported as rare compared to historical registry data for laser atherectomy.

Technological Characteristics

Materials: medical-grade tubing, optical fiber bundle. Energy: 308 nm excimer laser. Dimensions: 0.9-2.5 mm tip diameter, 100 cm working length. Configurations: over-the-wire and rapid-exchange. Standards: ISO 10993 (biocompatibility), ISO 11135 (sterilization), ISO 10555-1 (catheter requirements). Sterilization: ethylene oxide.

Indications for Use

Indicated for endovascular treatment of symptomatic infrainguinal lower extremity vascular disease in patients where total obstructions cannot be crossed with standard guide wires.

Regulatory Classification

Identification

### IDENTIFICATION OF PREDICATE DEVICES

The Safe Cross Radio Frequency Total Occlusion Crossing System (IntraLuminal Therapeutics, Inc.), which received market clearance under 510(k) K031842, is the primary predicate device. Other predicate devices include: Rotablator Rotational Angioplasty Systems (Heart Technology, Inc.) cleared under 510(K) applications K901206 and K933328, the Frontrunner CTO Catheter (LuMend, Inc.) cleared inder 510(k) K023114, and the Silverhawk Peripheral Catherer System (Foxhollow) cleared under under 510(k) K024243.

#### DEVICE DESCRIPTION

Spectranetics laser atherectorny catheters 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. Both over-the-wire and rapid-exchange catheter configurations are available. Laser energy impinged on a blockage ablates, or debulks, the lesion material thus opening the vessel, permitting placement of devices used in vascular interventions.

Spectranetics laser catheters are supplied in several models having tip diameters between 0.9 mm and 2.5 mm, appropriate for interventional use in peripheral arteries. Both over-the-wire and rapid exchange models are available.

#### INTENDED USE

CLiRpath™ catheters are intended for use in ablating a channel in totally occlusive peripheral vascular disease (including the superficial femoral, popliteal and infrapopliteal arteries), for enhancing the potential for limb preservation.

#### COMPARISON TO PREDICATE DEVICES

Spectranetics laser catheters for peripheral use are substantially equivalent in form, fit. and function to four (4) predicate devices, which have received market clearance inder section 510(k) rules.

Each of the devices is a catheter, i.e. a piece of tubing with a working length of approximately 100 cm, and a diameter between 0.9 mm and 6.0 mm. The catheters communicate mechanical and/or radiant energy to an occlusion within a patient's arteries in the lower limbs. Communicated energy disrupts occlusive material, such as arterial plaque, and permits its removal either when the catheter is withdrawn, soch as patient's endoreticular system. The pathway opened by each of the devices from the the subsequent placement of other devices and interventions.

# BIOCOMPATIBILITY, STERILIZATION, PACKAGING, AND BENCH TESTING

Biocompatibility of component materials and finished CLiRpath devices has been 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.

CLiRpath device integrity and functionality were qualified and/or validated using samples produced under routine manufacturing conditions. All excimer laser CLiRopath gathleter 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.

#### CLINICAL STUDIES

Forty-seven (47) patients with distal peripheral arterial disease were enrolled at investigational sites in the United States, Germany, and Belgium. The CLIRpath step by step excimer laser catheter procedure successfully crossed 79% of lesingsm step in to crossing with conventional guidewires. Overall procedural success was achieved in 72% of the cases, and straight-line blood flow was re-established to the foot in 79% of the cases. Serious adverse events associated with CLiRpath step by step treatments were more rare than those observed during a larger registry study of laser atherectomy in the arteries of the legs.

#### CONCLUSION

Human clinical studies verified the safety and performance characteristics for Spectranetics CLiRpath excimer laser catheters for use in the treatment of peripheral arterial disease. In vitro laboratory tests, as well as qualification and validation studies, have confirmed that CLiRpath catheters meet manufacturing and design specifications. All of these data combined establish substantial equivalence to the predicate devices,
