• Device Name: OCELOT CATHETER
• Applicant: Avinger, Inc.
• Product Code: PDU · Cardiovascular
• Decision Date: Dec 7, 2012
• Decision: SESE
• Submission Type: Special
• Regulation: 21 CFR 870.1250
• Device Class: Class 2

Intended Use

The Ocelot System is intended to facilitate the intraluminal placement of conventional guidewires beyond stenotic lesions (including sub and chronic total occlusions) in the peripheral vasculature prior to further percutaneous intervention using OCT-assisted orientation as an adjunct to fluoroscopy. The Ocelot System is contraindicated for use in the iliac, coronary, cerebral, renal or carotid vasculature.

Device Story

Ocelot System facilitates guidewire placement across peripheral vascular stenotic lesions; includes Ocelot Catheter, Lightbox Console, and Umbilical. Catheter is over-the-wire, compatible with 6F sheath and 0.014" guidewire. Incorporates optical fiber for Optical Coherence Tomography (OCT) imaging; provides real-time visualization as adjunct to fluoroscopy to assist physician orientation during navigation. Operated by physicians in clinical settings. OCT input transforms into visual output on console, allowing clinicians to distinguish vessel lumen from plaque/occlusion, guiding manual advancement of catheter. Benefits include improved navigation accuracy in complex occlusions, reducing risk of vessel perforation.

Clinical Evidence

Bench testing only. No clinical data provided. Testing included visual/dimensional verification, tensile, torque, guidewire advancement, device advancement, tip deflection, leak testing, spiral blade functional testing, coating friction, tip penetration, in vitro simulated use, shelf life, and tip-stall testing. All results met pre-determined specifications.

Technological Characteristics

Over-the-wire percutaneous catheter (110cm length). Features optical fiber for OCT imaging. Distal tip incorporates hybrid spiral flute and bilateral wedge design. Materials include torque coil, hypotube, and strain relief components. Energy source: optical (for OCT). Connectivity: connects to Lightbox Console via Umbilical. Sterilization: not specified.

Indications for Use

Indicated for patients requiring intraluminal guidewire placement beyond stenotic lesions, including subtotal and chronic total occlusions, in peripheral vasculature. Contraindicated for iliac, coronary, cerebral, renal, or carotid vasculature.

Regulatory Classification

Identification

#### D. Device Name

| Trade Name: | Ocelot Catheter |
|----------------------|-----------------------|
| Common Name: | Percutaneous Catheter |

#### Device Classification E.

| Classification: | 21 CFR §870.1250 |

| Product Code: | DQY |
| Device Class: | Class II |

#### F. Predicate Device

The Ocelot Catheter is substantially equivalent to the original Ocelot Catheter (K122380).

#### G. Device Description

The Ocelot System consists of the Ocelot Catheter, the Lightbox Console and the Umbilical. The Ocelot Catheter is an over-the-wire device that is compatible with a 6F sheath and 0.014" guidewire. The Ocelot Catheter has a working length of 110cm and incorporates an optical fiber used to facilitate Optical Coherence Tomography (OCT)-assisted orientation as an adjunct to fluoroscopy.

#### Intended Use H.

The Ocelot System is intended to facilitate the intraluminal placement of conventional guidewires beyond stenotic lesions (including sub and chronic total occlusions) in the peripheral vasculature prior to further percutaneous intervention using OCT-assisted orientation as an adjunct to fluoroscopy. The Ocelot System is contraindicated for use in the iliac, coronary, cerebral, renal or carotid vasculature.

#### Substantial Equivalence I.

The Ocelot Catheter is substantially equivalent to the originally cleared Ocelot Catheter (K122380). The subject and predicate devices have the same mechanism of action (manual advancement) and perform the same function (placement of guidewires beyond stenotic lesions in the peripheral vasculature). The design changes implemented to create Ocelot NEXT include a slightly larger torque coil and modified torque shaft, a longer hypotube in the handle assembly, a strain relief just distal to the rotator knob, the addition of a coil around the shaped distal segment and a modified spiral flute design in the distal tip. The modified distal tip represents a hybrid between the original Ocelot Catheter spiral flute configuration and the Wildcat Catheter's bilateral wedges (K111338). The changes to the Ocelot Catheter cleared under K122338 results in no significant changes to technological characteristics and do not raise any new issues of safety or effectiveness.

#### Non-Clinical Performance Data ).

The following non-clinical testing was previously conducted with the Ocelot Catheter to support a determination of substantial equivalence to the predicate Tip penetration testing was performed to ensure the catheter did not device. advance when the tip is engaged in tissue.

and external standard requirements. Results of non-clinical testing demonstrated that the Ocelot Catheter is substantially equivalent to the predicate device for the stated intended use.

#### K. Conclusions

The Ocelot Catheter has been carefully compared to legally marketed devices with respect to intended use and technological characteristics. Non-clinical testing was conducted to validate the performance of the devices and ensure the Ocelot Catheter functions as intended and meet design specifications. The comparison and nonclinical results demonstrate that the devices are substantially equivalent to the predicate device for the stated intended use.
