Indications for Use
The Auryon™ Atherectomy System and Auryon Atherectomy Catheters with aspiration are indicated for use as atherectomy devices for arterial stenoses, including in-stent restenosis (ISR), and to aspirate thrombus adjacent to stenoses in native and stented infra-inquinal arteries. The Auryon ™ Atherectomy System and Auryon Atherectomy Catheters without aspiration are indicated for use in the treatment, including atherectomy, of infra-inquinal stenoses and occlusions.
Device Story
Auryon Atherectomy System consists of laser console and single-use catheter; catheter features array of optic fibers surrounded by circumferential blunt blade. System operates over standard guidewire; delivers UV laser pulses (355 nm) to target site. Laser energy creates cavitation bubbles in fluid; collapse of bubbles generates photoacoustic shockwaves to disintegrate calcified lesions without thermal degradation. Used in clinical settings by physicians for peripheral artery disease treatment. Output is mechanical disintegration of stenotic material; aspiration feature (on specific models) removes debris/thrombus. Provides minimally invasive debulking of arterial occlusions; improves vessel patency.
Clinical Evidence
Bench testing only. No clinical data presented. Performance testing included catheter dimensions, trackability, pull tests, torque strength, fatigue, optical functionality/durability, and hydrophilic coating evaluation. Sterilization validated via bioburden and LAL testing.
Technological Characteristics
Laser atherectomy catheter; 355 nm wavelength; 50-60 mJ/mm² fluence; 40Hz pulse rate; 10-25ns pulse duration. Features optic fiber array and circumferential blunt blade.

#### DEVICE DESCRIPTION
The Auryon™ Atherectomy System consists of two sub-units: 1) a single use catheter ("Auryon catheter"); and 2) a laser console. The Auryon catheter is a single use catheter that is made of an array of optic fibers surrounded by a circumferential blunt blade at its distal tip. The Auryon™ catheter is connected to the laser system via its connector and transmits energy at pre-set fluence levels of 50 and 60 mJ/mm2 to the occluded or narrowed artery. The laser delivers very short high intensity pulses which travel from the laser, through the fibers, and emerge from the polished ends of the individual fibers. As the UV light emerges from the fiber end, it will be absorbed by the fluid, and create a cavitation bubble within the fluid. The collapse of this bubble results in a photoacoustic shockwave that disintegrates rigid materials such as calcified lesions without relying on thermal degradation to break down the stenotic material.
The Auryon™ Atherectomy System must work over a commercially available guide wire that crosses the lesion intra-luminally. The catheters are available in seven configurations (0.9mm, 0.9mm, 1.5mm, 1.5mm XL, 1.7mm, 2.0mm and 2.35mm), with and without hydrophilic coating.
For the small size catheters (i.e., 0.9mm.1.5mm, and 1.7mm), there is a designated lumen tube for a guidewire at the center of the inner blunt blade. The 0.9mm, 1.5mm, and 1.7mm catheters do not have an aspiration feature and have not been tested in ISR lesions.
The larger Auryon catheters (i.e., 2.0mm and 2.35mm) have an eccentric guidewire lumen and include additional features consisting of an aspiration feature (both catheters) and an "off-center" feature 2.35mm only. The aspiration feature is intended for debris and thrombus collection and removal from the vessel during the atherectomy procedure. These devices are also indicated for treatment of In-Stent Restenosis (ISR) lesions.
{5}------------------------------------------------
The "off-center" feature is included in the 2.35 mm catheter only and is designed to facilitate debulking of lesions in blood vessels beyond the catheter's diameter.
### INDICATION FOR USE
The Auryon™ Atherectomy System and Auryon Atherectomy Catheters with aspiration are indicated for use as atherectomy devices for arterial stenoses, including in-stent restenosis (ISR), and to aspirate thrombus adjacent to stenoses in native and stented infra-inguinal arteries.
The Auryon™ Atherectomy System and Auryon Atherectomy Catheters without aspiration are indicated for use in the treatment, including atherectomy, of infra-inguinal stenoses and occlusions.
### COMPARISON OF TECHNOLOGY CHARACTERISTICS WITH THE PREDICATE DEVICE
The proposed Auryon Atherectomy System is substantially equivalent to the predicate Auryon Atherectomy K233668. Both laser atherectomy devices have identical laser wavelength (355 nm), laser fluence levels (50 and 60 ml/mm²), pulse rate (40Hz), pulse duration (10-25ns), maximum output (33.5ml) and materials. The difference between the proposed device and predicate device is the addition of a 1.7mm catheter (1.75mm/0.069inch diameter) with a 150cm long working length. The 1.7mm catheter is offered both with and without a hydrophilic coating. The technological characteristic of the proposed device is substantially equivalent with the respect of the system design and function to that of the specified predicate device.
### DEVICE MODIFICATIONS AND RISK ASSOCIATED WITH THE DESIGN MODIFICATION(S)
Modifications made to the Auryon Atherectomy System were limited to introducing a 1.7mm Catheter. There is no change to the principles of operations, indications for use, intended purpose, technology characteristics, between the proposed system and the predicate.
The impact of the change as described within this submission were evaluated a part of the Risk analysis activity in terms of new/existing risks and new/existing failure modes. The results of this Risk Analysis activity were compared to the current risk Analysis; the conclusion drawn from this assessment, determined that the additional catheter size did not impact or modify an existing risk nor necessitate a new or modified risk.
#### COMPARISON OF PERFORMANCE DATA
The new 1.7mm Aurvon Atherectomy System Catheter was tested using the same methods and acceptance criteria as the predicate device. Specific tests are listed below:
- . Catheter Shaft OD, ID, Working Length
- Guard Tube Length
- Catheter Trackability (Simulated Use)
- Shaft Pull Test
- . Inner Blade Pull Test
- Proximal Section Pull Test .
- . Luer Pull vs Handle Pull Test
- . Distal Tip Evaluation
- Optical Functionality Test
- Catheter Torque Strength
- Fatigue Test
- Catheter Optical Durability
- Evaluation of Hydrophilic Coating ●
### STERILIZATION VALIDATION
Both the proposed 1.7mm Auryon Atherectomy System Catheter and the predicate Auryon Atherectomy System Catheters will be sterilized via the same process. Sterilization Validation on the proposed 1.7mm Auryon Atherectomy System Catheter was conducted per the below:
- Bioburden Determination ●
- LAL Testing
{6}------------------------------------------------
## CONCLUSION
Assessment of the similarities and differences of the proposed Auryon Atherectomy System and the predicate Auryon Atherectomy System concludes that the devices are substantially equivalent to one another; specifically:
- . The proposed and predicate device have the identical Pro-Code, Regulation Number, Regulation Name, and Regulatory Class;
- . The proposed and predicate device have identical Indications for Use;
- . The proposed and predicate devices incorporate the identical operating principle, mechanism of action, and are intended for the same patient populations; and,
- . With the exception of the newly added catheter size, the proposed and predicate employ an identical overall design, materials of manufacture, performance testing, sizes, and configurations.
The sum of these evaluations and determinations lead Eximo Medical Ltd. to conclude that substantial equivalence has been demonstrated, and that the existing data and additional testing have confirmed that there are no new questions of safety or effectiveness.
