More Information

No
The summary focuses on the mechanical design and performance of the catheter and aspiration system, with no mention of AI or ML in the device description, intended use, or performance studies.

Yes.
The device is used for revascularization and tissue plasminogen activator therapy, which are therapeutic medical interventions.

No

The device is indicated for revascularization in patients with acute intracranial large vessel occlusive disease, which is a treatment rather than a diagnostic purpose.

No

The device description clearly details physical hardware components including a catheter, tubing set, and pump, made of materials like Stainless-Steel and Nitinol.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use clearly describes a device used for the revascularization of patients with acute intracranial large vessel occlusive disease. This is a therapeutic intervention performed in vivo (within the body) to restore blood flow.
  • Device Description: The device description details a catheter, aspiration tubing, and a pump. These are all components used for a medical procedure performed directly on the patient.
  • Lack of Diagnostic Purpose: There is no mention of the device being used to diagnose a condition, analyze samples (like blood or tissue), or provide information about a patient's health status based on in vitro testing.
  • Performance Studies: The performance studies focus on the device's ability to achieve revascularization (effectiveness) and its safety during the procedure, not on its diagnostic accuracy.

IVD devices are used to examine specimens derived from the human body (like blood, urine, or tissue) to provide information for diagnostic, monitoring, or compatibility purposes. This device does not fit that description.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

Animal Testing:
Clot was used to create occlusions within several arteries of swine. One side of each swine was treated with the subject Zenith Flex system and the contralateral side was treated with the reference device. The study included two follow up evaluations: 3 days and 30 days. There were 3 endpoints of the study: angiographic assessment of revascularization to establish effectiveness, angiographic assessment and histopathological assessment to demonstrate safety. As testing included the reference device, results were compared to demonstrate substantial equivalence.

Zenith Flex Performance Testing (Bench Testing):
To demonstrate substantial equivalence between the subject 074 Zenith Flex Catheter and the predicate 071 Zenith Flex Catheter and the reference Penumbra ACE 68 Catheter, performance testing was conducted. The testing covered verification and validation testing, including biocompatibility, bench testing, sterilization and shelf life. Additionally, some tests were leveraged from previous testing conducted by InNeuroCo. The tests were performed using standard test methods and pre-determined acceptance criteria and all samples passed.

Key results from bench testing (all samples met acceptance criteria):

  • Biocompatibility (Material Mediated Pyrogen, Cytotoxicity MEM Elution, Hemolysis (ASTM Method, extract human blood), Unactivated Partial Thromboplastin Time, Complement Activation, Dog Thromboresistance, Maximization Sensitization, Intracutaneous Toxicity/Reactivity, Acute Systemic Toxicity Test)

Performance Data - Clinical:
No clinical study was conducted as bench and animal testing was determined sufficient for verification and validation purposes. A review was conducted considering published clinical study articles that featured the Reference Device and other devices with similar dimensions used for direct aspiration. The literature review was used to support the proposed indications for use under the NRY product code by leveraging clinical outcomes from devices that are considered technologically similar.

Summary of Non-Clinical Data

The subject device has the same materials, packaging, manufacturing process, and sterilization process as the predicate device. Therefore, testing was only conducted for specifications that were affected by the catheter size change.

Animal Testing

Clot was used to create occlusions within several arteries of swine. One side of each swine was treated with the subject Zenith Flex system and the contralateral side was treated with the reference device. The study included two follow up evaluations: 3 days and 30 days.

8

There were 3 endpoints of the study: angiographic assessment of revascularization to establish effectiveness, angiographic assessment and histopathological assessment to demonstrate safety. As testing included the reference device, results were compared to demonstrate substantial equivalence.

Zenith Flex Performance Testing

To demonstrate substantial equivalence between the subject 074 Zenith Flex Catheter and the predicate 071 Zenith Flex Catheter and the reference Penumbra ACE 68 Catheter, performance testing was conducted. The testing covered verification and validation testing, including biocompatibility, bench testing, sterilization and shelf life. Additionally, some tests were leveraged from previous testing conducted by InNeuroCo. The tests were performed using standard test methods and pre-determined acceptance criteria and all samples passed. Therefore, this test data supports the argument that the 074 Zenith Flex Catheter has similar performance characteristics as the predicate device and the reference device. All of the testing conducted to demonstrate substantial equivalence are presented in the following table.

Performance Data - Clinical

No clinical study was conducted as bench and animal testing was determined sufficient for verification and validation purposes. A review was conducted considering published clinical study articles that featured the Reference Device and other devices with similar dimensions used for direct aspiration. The literature review was used to support the proposed indications for use under the NRY product code by leveraging clinical outcomes from devices that are considered technologically similar.

Summary of Substantial Equivalence

The performance characteristics and the test results demonstrate that the 074 Zenith Flex Catheter meets the acceptance criteria to determine that the 074 Zenith Flex Catheter is substantially equivalent to the predicate device. Furthermore, the intended use, the operating principles, the design, materials and the results of biocompatibility testing, shelf-life, packaging and sterilization processes are all equivalent and support the all devices are
