The Penumbra Embolectomy Aspiration System is intended for the removal of fresh, soft emboli and thrombi from vessels of the peripheral arterial system. Not for use in the coronaries, the venous system or the neurovasculature.

Device Story

System utilizes aspiration to remove fresh, soft emboli/thrombi from peripheral arterial vessels. Components include aspiration catheter, separator, and aspiration tubing. Separator functions to break up clot within catheter to facilitate aspiration. Used in clinical settings by physicians. Device is sterile, single-use. Performance verified via bench-top mechanical testing and animal studies confirming safety and efficacy. Output is physical removal of thrombus, benefiting patient by restoring blood flow.

Clinical Evidence

No human clinical data. Evidence consists of biocompatibility testing (EN ISO 10993-1), bench-top mechanical testing (visual/dimensional, tensile, bond, burst, friction, flow, torsion, simulated use, particulate, flexibility), and animal studies. Animal studies showed no vessel injury, no abnormal histology, and no significant vascular response.

Technological Characteristics

Components: aspiration catheter, separator, aspiration tubing. Materials: biocompatible per EN ISO 10993-1. Sterilization: ethylene oxide (double cycle). Principle: mechanical aspiration. Form factor: intravascular catheter system. Connectivity: none (standalone).

Indications for Use

Indicated for removal of fresh, soft emboli and thrombi from peripheral arterial system vessels. Contraindicated for use in coronary, venous, or neurovascular systems.

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.

#### Device Description 9.8

The Penumbra Embolectomy Aspiration System's fundamental mechanism of action is aspiration. Aspiration draws the embolus or thrombus into the Aspiration Catheter to remove the embolus or thrombus from the body. All Separators function to break up the clot inside of the catheter to make it more amenable to removal from the body via aspiration. The Aspiration Catheter, Separator and Aspiration Tubing are available in multiple configurations. The devices are provided sterile, non-pyrogenic, and intended for single use only.

#### و. و Intended Use

The Penumbra Embolectomy Aspiration System is intended for the removal of fresh, soft emboli and thrombi from vessels of the peripheral arterial system. Not for use in the coronaries, the venous system or the neurovasculature.

# 9.10 Summary of Non-Clinical Data

As required under Section 12, Part (a)(i)(3A) of the Safe Medical Devices Act of 1990. a summary of any information regarding safety and effectiveness of the device follows.

Included in this section are descriptions of the testing, which substantiates the safe and effective performance of the Penumbra Embolectomy Aspiration System as well as its substantial equivalence to the predicate devices:

- . Biocompatibility / Pyrogenicity
- . Design Verification (Bench-Top Testing)
- . Animal Study

For the subject Penumbra Embolectomy Aspiration System all established requirements and acceptance criteria were met.

## 9.10.1 Biocompatibility Testing

Biocompatibility is established for the Penumbra Embolectomy Aspiration System devices based on tests selected in accordance with EN ISO 10993 -1 guidelines (Biological Evaluation of Medical Devices) for limited duration (<24 hours), external communicating devices, contacting circulating blood. All studies were conducted pursuant to 21 CFR, Part 58, Good Laboratory Practices. In summary, non-clinical testing found the Penumbra Embolectomy Aspiration

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

System devices to be biocompatible according to the requirements of EN ISO 10993 requirements. In summary the following tests were performed:

| Test | Method | Result |
|-------------------------------------------|----------------------------------------------|-----------------------------------------------------------------|
| Cytotoxicity | L929 MEM Elution<br>Test | Non-Toxic |
| Sensitization | Kligman Maximization | Non-Sensitizing |
| Intracutaneous<br>Reactivity (Irritation) | Intracutaneous Injection<br>Test | Non-Irritant |
| Systemic Toxicity<br>(Acute) | ISO Acute Systemic<br>Injection Test | Non-Toxic |
| Haemocompatibility | Complement Activation | No greater biological<br>response than<br>corresponding control |

The results of the tests appropriately address the physical and mechanical performance expectations of the device. This is further supported by the surgical handling and performance results reported in the in vivo study. Based on these overall results, the physical and mechanical properties of the Penumbra Embolectomy Aspiration System devices are acceptable for the intended use and substantially equivalent to the predicate devices.

## 9.10.3 Animal Study

Animal studies were conducted to evaluate the safe use of the Penumbra Embolectomy Aspiration System devices. The studies concluded that:

- No vessel injury was noted on the final angiograms following the vessel ● response procedure.
- No abnormal gross or histology findings were noted in test vessel segments. .
- The use of the devices resulted in no significant vascular response in these . experimental conditions.

### 9.10.4 Summary of Substantial Equivalence
