Indications for Use
The Auryon™ Atherectomy System and Auryon Atherectomy Catheters with aspiration are indicated for use as atherectorny 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™ Atherectory System and Auryon Atherectomy Catheters without aspiration are indicated for use in the treatment, including atherectomy, of infra-inguinal stenoses and occlusions.
Device Story
Auryon Atherectomy System uses laser energy to treat arterial stenoses and occlusions. System consists of single-use catheters with optic fiber arrays and circumferential blunt blades at distal tips. Catheters connect to laser console, transmitting energy at 50 and 60 mJ/mm² to debulk lesions. Larger catheters (2.0mm, 2.35mm) include aspiration for debris/thrombus removal and eccentric guidewire lumens; 2.35mm model features 'off-center' capability for larger vessel debulking. Subject device adds hydrophilic coating to catheter shaft to reduce friction. Used in clinical settings by physicians; device tracks over 0.014" guidewires. Output is physical debulking of arterial plaque and thrombus aspiration, improving vessel patency. Benefits include minimally invasive treatment of peripheral artery disease and ISR.
Clinical Evidence
Bench testing only. Performance testing included catheter shaft dimensions, trackability in simulated anatomy, leakage testing (liquid/air), pull testing, optical functionality, and coating characterization (integrity and particulate generation). No clinical data presented.
Technological Characteristics
Single-use laser atherectomy catheters; optic fiber array with circumferential blunt blade. Sizes: 0.9mm, 1.5mm, 2.0mm, 2.35mm. Energy source: laser console (50-60 mJ/mm²).

Auryon™ Atherectomy System Peripheral Atherectomy Catheter 21CFR870.4875 Intraluminal Artery Stripper Class 2 MCW Cardiovascular Devices
## K202835
K220116
Auryon Atherectomy System Peripheral Atherectomy Catheter 21CFR870.4875 Intraluminal Artery Stripper Class 2 MCW Cardiovascular Devices
## Purpose
The purpose of this 510(k) is to introduce into commercial distribution four new catheter item codes for use with the existing Auryon Atherectomy System which will have a hydrophilic coating on the external distal portion of the catheter shaft. The size range, intended purpose, and Indications for Use will be the same as the existing Auryon Atherectomy Catheters.
## Device Description
The Auryon™ Atherectomy Catheters are single use catheters made of an array of optic fibers and surrounded by a circumferential blunt blade at its distal tip. The Auryon catheter is connected to the laser of the predicate device Auryon Atherectomy System via its connector and transmits energy at pre-set fluence levels of 50 and 60 ml/mm² to the occluded or narrowed artery. The Auryon™ Atherectomy Catheter must work over a commercially available 300cm 0.014" guide wire that crosses the lesion intra
{4}------------------------------------------------
luminally. The new catheters which are the subject of this 510(k) include a hydrophilic coating on the external distal portion of the catheter shaft.
The predicate device Auryon Atherectomy Catheters are available in four sizes (0.9mm, 1.5mm, 2.0mm and 2.35mm, without hydrophilic coating. The subject device Auryon Atherectomy Catheters are available in the same four sizes (0.9mm, 1.5mm, 2.0mm and 2.35mm, but with a hydrophilic coating.
For the small size catheters (i.e., 0.9mm and 1.5mm), there is a designated lumen tube for a guidewire at the center of the inner blunt blade. The 0.9mm and 1.5mm 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.
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.
# 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-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 Performance Data
The hydrophilic coated Auryon Atherectory Catheters were tested using the same methods and acceptance criteria as was done in the predicate device 510(k). In addition, coating performance was tested, with comparison to the performance of the reference device K170059. The specific tests are listed below
#### Summary of Performance Testing
Catheter shaft ID, OD, working length, and length of hydrophilic coating Catheter trackability in simulated anatomical shape Freedom from leakage during liquid infusion, and air leakage during aspiration (2.0 and 2.35mm sizes) Pull testing of catheter tip and catheter to handle joints Freedom from exposed optical fibers Catheter torque test Optical Functionality test Coating Characterization Coating integrity and particulate generation after simulated use
# Substantial Equivalence
Assessment of the similarities and differences of the proposed hydrophilic coated Auryon Atherectomy Catheters and the predicate Auryon Atherectomy System and the reference device Spectranetics Turbo-Elite Laser Atherectomy Catheters concludes that the devices are substantially equivalent to one another; specifically:
- . The proposed and predicate device have the identical ProCode, Regulation Number, Regulation Name, and Regulatory Class;
- The proposed and predicate devices have the same Intended Use;
- The proposed and reference device K221077 have the same 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,
- The proposed and predicate catheters employ an identical overall design, essentially identical materials of manufacture, performance testing, sizes, and configurations.
- The proposed device and the reference device K170059 employ hydrophilic coatings that are similar in formulation, performance, and intended purpose (reduction of friction).
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.
