Intended Use

The Kittycat Catheter 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. The Kittycat Catheter is contraindicated for use in the illac, coronary, cerebral or carotid vasculature. The Kittycat 2 Catheter 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. The Kittycat Catheter is contraindicated for use in the iliac, coronary, cerebral or carotid vasculature.

Device Story

Percutaneous catheter designed to facilitate guidewire placement across peripheral vascular stenotic lesions and chronic total occlusions. Device comprises catheter shaft, proximal handle assembly, and rotating distal tip. Kittycat model features slider-based distal tip deflection; Kittycat 2 model features pre-shaped distal tip. Operated manually by physician in clinical setting. Device provides mechanical path for guidewire advancement. Single-use, sterile. Benefits include improved access to distal vasculature for subsequent percutaneous interventions.

Clinical Evidence

Bench testing only. Testing included visual/dimensional verification, tensile, torque, guidewire advancement, device advancement, spiral blade functional testing, coating friction, biocompatibility, in vitro simulated use, tip deflection, leak testing, flexibility/trackability, shipping, shelf life, and sterility. All results met pre-determined specifications.

Technological Characteristics

Catheter shaft with proximal handle and rotating distal tip. Working lengths: 140 cm (Kittycat) and 150 cm (Kittycat 2). Distal tip features spiral flutes. Sterilized via irradiation. Single-use. Mechanical operation; no energy source or software.

Indications for Use

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

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

#### D. Device Name

| Trade Name: | Kittycat and Kittycat 2 Catheters |
|----------------------|-----------------------------------|
| Common Name: | Percutaneous Catheter |
| Classification Name: | Percutaneous Catheter |

#### Device Classification E.

| Classification: | 21 CFR §870.1250 |
|-----------------|------------------|
| Product Code: | DQY |
| Device Class: | Class II |

#### E. Predicate Device

The Kittycat and Kittycat 2 Catheters are substantially equivalent to the Avinger Wildcat 6F Catheter (K111338).

#### G. Device Description

The Kittycat Catheters consist of a Catheter Shaft with a Handle assembly at the proximal end and a rotating Distal Tip. The Kittycat Catheters have a working length of 140 cm and 150 cm for the Kittycat and Kittycat 2, respectively. A locking Luer at the proximal provides entry to a lumen that supports and facilitates movement of a guidewire. The Kittycat Catheters have been irradiated for sterility and are intended for single-use only. The Kittycat Catheters are fundamentally the same device and only differ in handle design and Distal Tip

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

deflection mechanism: the Kittycat Catheter utilizes a slider-based Distal Tip deflection mechanism while the Kittycat 2 Catheter utilizes a pre-shaped Distal Tip.

### H. Intended Use

The Kittycat Catheter 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. The Kittycat Catheter is contraindicated for use in the illac, coronary, cerebral or carotid vasculature.

The Kittycat 2 Catheter 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. The Kittycat Catheter is contraindicated for use in the iliac, coronary, cerebral or carotid vasculature.

#### l, Substantial Equivalence

The Kittycat Catheters are substantially equivalent to the Avinger Wildcat 6F Catheter (K111338) and original Kittycat Catheters (K101647 and K112579). 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 only difference is the use of spiral flutes in the Distal Tip on the Kittycat Catheters as opposed to bilateral wedges as on the Wildcat 6F Catheter. The changes to the Wildcat 6F Catheter cleared under K111338 results in no significant changes to technological characteristics and do not raise any new issues of safety or effectiveness.

#### Non-Clinical Performance Data J.

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

| • Visual and Dimensional Verification | • Spiral Blade Functional Testing |
|---------------------------------------|-----------------------------------|
| • Tensile Testing | • Coating Friction Testing |
| • Torque Testing | • Biocompatibility |
| • Guidewire advancement | • In Vitro Simulated Use Testing |
| • Device Advancement | • Packaging Testing |

{2}------------------------------------------------

| · Tip Deflection Testing | · Shipping Testing |
|----------------------------|---------------------------|
| · Device leak testing | · Shelf Life Testing |
| · Luer Leak Testing | · Sterility Testing |
| · Flexibility/Trackability | · Tip Penetration Testing |

The above testing confirmed that the Kittycat Catheters performs according to the stated intended use. All data fell well within pre-determined product specifications and external standard requirements. Results of non-clinical testing demonstrated that the Kittycat Catheters are substantially equivalent to the predicate device for the stated intended use.

#### K. Conclusions

The Kittycat Catheters have 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 Kittycat Catheters function as intended and meet design specifications. The comparison and non-clinical results demonstrate that the devices are substantially equivalent to the predicate device for the stated intended use.
