Intended Use

The Symphony Thrombectomy System is intended for: - The non-surgical removal of fresh, soft emboli and thrombi from blood vessels. - Injection, infusion, and/or aspiration of contrast media and other fluids into or from a blood vessel. The Symphony Thrombectomy System is intended for use in the peripheral vasculature. It is not for use in the pulmonary vasculature.

Device Story

System removes thrombus/embolus from peripheral vasculature via controlled aspiration. Components include catheters (16F/24F), dilators, ProHelix assist device, generator, canister, and tubeset. Physician introduces catheter over guidewire to thrombus site under fluoroscopic guidance. ProHelix may be advanced through catheter; manual rotation of ProHelix handle facilitates thrombus removal. Generator provides vacuum source for aspiration. System used in clinical setting by physicians. Output is physical removal of thrombus; visualization provided by radiopaque markers under fluoroscopy. Benefits include non-surgical clot removal, restoring blood flow.

Clinical Evidence

Bench testing only and GLP animal study. Bench tests: visual/dimensional, kink/bend, tensile/torque, pressure/leak, lumen integrity, burst, fluoroscopy, simulated use, corrosion, coating, particulate, drop, and fatigue testing. GLP animal study: assessed acute/chronic safety, performance, and in-vivo thrombogenicity; no vascular injuries or complications observed; all vessels free from thrombus.

Technological Characteristics

System includes catheters, dilators, ProHelix, generator, canister, and tubeset. Materials: medical-grade plastics and metals. Catheters feature hydrophilic coating on distal shafts. Sensing/actuation: manual rotation of ProHelix tip; vacuum-based aspiration via generator. Connectivity: standalone system. Sterilization: Ethylene Oxide (EO).

Indications for Use

Indicated for non-surgical removal of fresh, soft emboli and thrombi from peripheral vasculature; injection, infusion, or aspiration of contrast media/fluids. Not for use in pulmonary vasculature.

Regulatory Classification

Identification

An embolectomy catheter is a balloon-tipped catheter that is used to remove thromboemboli, i.e., blood clots which have migrated in blood vessels from one site in the vascular tree to another.

#### Intended Use / Indications for Use:

The TRUVIC Medical, Inc. (TRUVIC) Symphony Thrombectomy System is intended for:

- The non-surgical removal of fresh, soft emboli and thrombi from blood vessels.
- . Injection, infusion, and/or aspiration of contrast media and other fluids into or from a blood vessel.

The Symphony Thrombectomy System is intended for use in the peripheral vasculature. It is not for use in the pulmonary vasculature.

{4}------------------------------------------------

# Device Description:

The Symphony Thrombectomy System is comprised of several devices:

| • 24F Symphony Catheter | • 16F Symphony Catheter | • TRUVIC Generator |
|-----------------------------------------|--------------------------|--------------------|
| • 24F Symphony Dilator | • 16F Symphony Dilator | • TRUVIC Canister |
| • 24F Symphony Advance™<br>Long Dilator | • 16F Symphony ProHelix™ | • TRUVIC Tubeset |

- 24F Symphony ProHelix™
The Symphony Thrombectomy System is designed to remove thrombus/embolus (also referred to as 'thrombus' or 'clot') from the peripheral vasculature using controlled aspiration. The Symphony Catheter targets aspiration from the TRUVIC Generator directly to the thrombus. The Symphony ProHelix may be used to facilitate aspiration and removal of the thrombus through the Symphony Catheter.

The Symphony Catheter has a lubricious hydrophilic coating on the distal 40 cm of the 24F catheter shaft, and distal 55 cm of the 16F catheter shaft. The Symphony Catheters and Symphony Dilators are introduced through a vascular access sheath into the peripheral vasculature and guided over a guidewire to the site of the thrombus. The Symphony Catheter is used with the TRUVIC Generator, connected using the TRUVIC Tubeset and the TRUVIC Canister, to aspirate thrombus.

As needed, the Symphony ProHelix may be introduced through the Symphony Catheter to assist with thrombus removal. The Symphony ProHelix is manually advanced through the Symphony Catheter over a guidewire, remaining inside the Symphony Catheter during the procedure. During aspiration, the handle on the proximal end of the Symphony ProHelix is manually rotated, which rotates the tip of the Symphony ProHelix to facilitate thrombus removal through the Symphony Catheter. The tips of the devices are visible under fluoroscopy.

# Comparison with predicate device:

The subject device Symphony Thrombectomy System and the predicate Penumbra INDIGO System have the same intended use, operating principle, design concept, and sterilization processes. Both the subject and predicate systems utilize a catheter and wire-based device to facilitate thrombus removal, and both employ a continuous aspiration pump in this extraction function.

## Non-Clinical Testing / Performance Data:

Non-clinical laboratory testing was performed on the Symphony Thrombectomy System to assure compliance with all pre-specified, clinically relevant acceptance criteria and to determine substantial equivalence as it relates to the intended use. The following testing/assessments were performed:

- Visual and Dimensional Verification ●
- Kink / Bend Verification ●
- Actuation Force Verification ●
- Tensile and Torque Strength Verification ●
- Positive Pressure / Fluid Leak Verification
- Negative Pressure / Air Leak Verification ●
- Lumen Integrity Verification
- Burst Pressure Verification
- Fluoroscopy Validation (Visibility test)
- Simulated Use Performance Validation ●
- Corrosion Resistance Testing
- Coating Integrity Testing ●
- Acute Particulate Testing
- Drop Testing Verification
- . Component Fatigue Testing Verification

The in vitro bench tests demonstrated that the Symphony Thrombectomy System met all acceptance criteria. Performance data demonstrate that the Symphony Thrombectomy System functions as intended and is substantially equivalent to the predicate device.

{7}------------------------------------------------

# Biocompatibility:

Testing was performed to assess biocompatibility of the Symphony Thrombectomy System patient-contacting components. The following tests were successfully performed:

- Cytotoxicity
- Sensitization ●
- Intracutaneous Reactivity ●
- Acute Systemic Toxicity
- Material Mediated Pyrogenicity
- Hemocompatibility
- Direct and Indirect Hemolysis
- Sc5b-9 Complement Activation o
- In-Vivo Thrombogenicity (from GLP animal study) o

Adherence to the test methodologies and standards was maintained in all biocompatibility testing described. Each of the biocompatibility tests defined above passed. There was no evidence of toxicity, sensitization, or irritation. Testing found samples to be non-hemolytic, non-activator, and non-pyrogenic. All testing was conducted in compliance with GLP regulations, 21 CFR Part 58.

#### In-Vivo GLP Pre-Clinical Testing / Performance Data:

A GLP animal study was performed to assess the acute and chronic safety and performance of the Symphony Thrombectomy System. In-vivo thrombogenicity was also assessed.

There were no complications in Symphony Thrombectomy System device preparation or performance and no vascular injuries were observed. All treated vessels were free from thrombus formation in both acute and chronic cohorts. All acceptance criteria passed. The GLP animal study did not identify any new questions of safety or effectiveness for the TRUVIC Symphony Thrombectomy System in all measured assessments, and supports substantial equivalence to the predicate device.

## Conclusion:

The TRUVIC Symphony Thrombectomy System has the same intended use and the same or similar technological characteristics such as components, design, materials, sterilization method, and operating principles as the predicate device. Performance data demonstrates that the device functions as intended. The non-clinical and in-vivo pre-clinical tests demonstrate that the Symphony Thrombectomy System is substantially equivalent to the predicate device.
