Intended Use

The HawkOne Directional Atherectomy System is intended for use in atherectomy of the peripheral vasculature. The HawkOne catheter is indicated for use in conjunction with the SpiderFX Embolic Protection Device in the treatment of severely calcified lesions. The HawkOne catheter is NOT intended for use in the coronary, carotid, iliac or renal vasculature.

Device Story

HawkOne Directional Atherectomy System treats peripheral artery disease by removing atherosclerotic plaque. System comprises flexible catheter with distal rotating cutting assembly and battery-powered cutter driver. Physician advances catheter over 0.014" guidewire to lesion site; activates thumb switch to engage rotating blade; shaves occlusive material; captures excised tissue in catheter tip. Process repeated as needed. Used in clinical setting; requires SpiderFX Embolic Protection Device for severely calcified lesions to mitigate distal embolization. Output is physical removal of plaque, improving vessel patency.

Clinical Evidence

Bench testing only. Performance evaluated via device inspections, urge force, cycle/life testing, cutter height, tracking force, shaft torque, carbide edge attachment, tensile tests, catheter/driver interaction, embolization, cut mass per pass, tissue removal cycles, package integrity, and biocompatibility.

Technological Characteristics

Directional atherectomy catheter with rotating inner blade in tubular housing; battery-powered cutter driver; 0.014" guidewire compatible. Mechanical cutting principle. Sterilized via validated method. Standalone operation.

Indications for Use

Indicated for atherectomy of peripheral vasculature in patients with de novo and restenotic atherosclerotic calcified and non-calcified lesions. Use with SpiderFX Embolic Protection Device required for severely calcified lesions. Contraindicated for use in coronary, carotid, iliac, or renal vasculature.

### 4. Device Description

The HawkOne™ directional atherectomy system (HawkOne catheter and cutter driver) is designed for the treatment of de novo and restenotic atherosclerotic calcified and non-calcified lesions located in native peripheral arteries. When used in complex, hard, calcified lesions, the HawkOne catheter should be paired with the SpiderFX™ embolic protection device to mitigate risk of distal embolization that may be generated by the breakdown of heavily calcified plaque. The HawkOne catheter consists of a flexible shaft designed to track over a 0.014" guidewire. At the distal end of the HawkOne catheter is a small cutting assembly comprised of a rotating inner

blade contained within a tubular housing. The proximal end of the HawkOne catheter contains a connector and cutter positioning lever (thumb switch) designed to fit into the cutter driver. The cutter driver (catalog number H1-14550) is a battery driven, internally powered device, designed to power the HawkOne directional atherectomy catheter. For information about the SpiderFX embolic protection device, reference the Instructions for Use provided with the device.

The HawkOne directional atherectomy system has two switches: 1) the cutter driver main power switch and 2) the HawkOne catheter thumb switch. The cutter driver main power switch supplies power to the device when turned On. The HawkOne catheter thumb switch activates the drive shaft and engages the cutter when pulled proximally to the On position. With the cutter engaged, the HawkOne catheter is slowly advanced across the lesion, shaving occlusive material from the artery. The excised tissue is captured and stored in the tip of the device. The cutting process is completed by advancing the HawkOne catheter thumb switch distally, deactivating the drive shaft and disengaging the cutter. The HawkOne catheter thumb switch is fully advanced distally to the Off position in order to pack the excised plaque into the tip. This cutting sequence is repeated as necessary to achieve the desired degree of plaque excision.

### 5. Indications for Use

The HawkOne Directional Atherectomy System is intended for use in atherectomy of the peripheral vasculature. The HawkOne catheter is indicated for use in conjunction with the SpiderFX Embolic Protection Device in the treatment of severely calcified lesions. The HawkOne catheter is NOT intended for use in the coronary, carotid, iliac or renal vasculature.

#### 6. Comparison of Technological Characteristics

The proposed HawkOne Directional Atherectomy System is substantially equivalent to the currently marketed TurboHawk Peripheral Plaque Excision Systems (K111723 and K103618). The proposed and predicate devices share the following technological characteristics:

- Intended Use
- Fundamental scientific technology ●
- Principles of Operation ●
- . Conditions of Use
- Packaging Materials
- Sterilization site, method, parameters, and sterility assurance level

Additionally, the indications for use, labeling, device materials, and manufacturing site and methods are similar between the proposed and marketed devices.

#### 7. Performance Testing Summary

To demonstrate substantial equivalence of the proposed HawkOne Directional Atherectomy System to the predicate device, bench testing was performed.

Using internal Risk Analysis procedures, the following tests were performed:

- . Device Inspections
- Urge Force ●
- Cycle and Life
- Cutter Height
- Tracking Force ●
- . Repeated Cutter Spin Down and Packing

- Shaft Torque Tests ●
- Carbide Edge Attachment
- DFT Torque and Pressure Tests
- Device Tensile Tests ●
- . Catheter and Cutter Driver Interaction
- . Embolization
- . Cut Mass Per Pass (Tissue Removal Rate)
- Tissue Removal Cycles
- Package Integrity
- . Biocompatibility

The results from these tests demonstrate that the technological characteristics and performance criteria of the HawkOne Directional Atherectomy System are comparable to the predicate device and that the HawkOne Directional Atherectomy System performs in a manner equivalent to the predicate device currently on the market.

#### 8. Conclusions

Based on the intended use, technological characteristics, safety and performance testing included in this submission, Covidien considers the proposed HawkOne Directional Atherectomy System to be substantially equivalent to the currently marketed TurboHawk Peripheral Plaque Excision Systems (K11723 and K103618).
