Intended Use
The ZOOM Reperfusion Catheters, with the ZOOM Aspiration Tubing and ZOOM Aspiration Pump (or equivalent vacuum pump), are indicated for use in the revascularization of patients with acute ischemic stroke secondary to intracranial large vessel occlusive disease (within the internal carotid, middle cerebral - M1 and M2 segments, basilar, and vertebral arteries) within 8 hours of symptom onset. Patients who are ineligible for intravenous tissue plasminogen activator (IV t-PA) or who fail IV t-PA therapy are candidates for treatment. The ZOOM Aspiration Tubing is intended to connect the ZOOM Reperfusion Catheter of the ZOOM Aspiration Pump and to allow the user to control the fluid flow.
Device Description
The ZOOM™ Reperfusion Catheter is a single lumen, braid and coil reinforced, variable stiffness catheter that facilitates removal of thrombus/clot from the neurovasculature when connected to a vacuum source, such as the ZOOM Aspiration Pump, using the ZOOM Aspiration Tubing. The ZOOM Reperfusion Catheter is offered in various working lengths and nominal inner diameters (ID) and outer diameters (OD) as shown in Table 1. The ZOOM Reperfusion Catheter is comprised of a hollow cylindrical tube which is bonded to a standard luer fitting. The wall of the tube is constructed using a combination of metal coils/braids and medical grade polymers. The distal section of the ZOOM Reperfusion Catheter has a hydrophilic coating to enhance tracking through the vasculature. The beveled distal tip allows for atraumatic tracking past vessel branches during insertion. A radiopaque marker provides the user with visual confirmation of the distal tip location under fluoroscopy. The ZOOM Reperfusion Catheter is packaged with an accessory Rotating Hemostasis Valve (RHV). The RHV is designed to be attached to the proximal luer of the catheter and helps the user maintain hemostasis. The ZOOM Aspiration Tubing is offered in one model with the features indicated in Table 2. The ZOOM Aspiration Tubing is comprised of a hollow cylindrical tube which is bonded to a standard luer fitting that connects to the ZOOM Reperfusion Catheter and a slip fit connector that connects to the canister on the aspiration pump. The ZOOM Aspiration Tubing is made of common medical grade polymers.
More Information

No
The description focuses on the mechanical components and function of a catheter-based aspiration system for stroke treatment. There is no mention of AI or ML in the intended use, device description, or performance studies.

Yes
The device is indicated for use in the revascularization of patients with acute ischemic stroke, which directly treats a medical condition.

No

The device is indicated for revascularization and removal of thrombus/clot, which are therapeutic actions, not diagnostic ones.

No

The device description clearly outlines physical components like catheters, tubing, and a pump, indicating it is a hardware-based medical device.

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

Here's why:

  • IVD Definition: In Vitro Diagnostics are medical devices used to perform tests on samples taken from the human body (like blood, urine, or tissue) to provide information about a person's health.
  • Device Function: The ZOOM Reperfusion Catheters, Tubing, and Pump are used to physically remove blood clots from blood vessels in the brain during a stroke. This is a therapeutic intervention performed directly on the patient's body, not a test performed on a sample outside the body.
  • Intended Use: The intended use clearly states "revascularization of patients with acute ischemic stroke secondary to intracranial large vessel occlusive disease," which is a treatment procedure.
  • Device Description: The description details a catheter designed for insertion into blood vessels and connected to a vacuum source for aspiration, consistent with a therapeutic device.

Therefore, this device falls under the category of a therapeutic medical device, not an In Vitro Diagnostic.

G. Performance Data Supporting Substantial Equivalence:

Bench testing was completed to evaluate the differences between the subject ZOOM Reperfusion Catheters and predicate ZOOM Reperfusion Catheters. Performance specifications and test methods were based primarily on catheter performance standard ISO

8

10555-1 and a summary of the evaluated performance specifications is presented in Table 4 below.

The test results were reviewed and found to demonstrate that the differences between the subject ZOOM Reperfusion Catheters and predicate ZOOM Reperfusion Catheters do not significantly impact any performance parameters that would negatively affect the safety or effectiveness of the subject ZOOM Reperfusion Catheters and Aspiration Tubing.

Table 4: Tests and Performance Specifications for ZOOM Reperfusion Catheter

9

There were no changes to the Zoom Aspiration Tubing or Zoom Aspiration Pump and no changes to the subject and predicate ZOOM Reperfusion Catheters that would impact compatibility with these components. Therefore, no additional performance testing was required for the Zoom Aspiration Tubing or Zoom Aspiration Pump.

H. Biocompatibility Testing:

There are no changes to materials compared to the predicate device. Therefore, the original testing on the predicate devices applies to the subject devices and additional biocompatibility testing was not required.

I. Sterilization:

The ZOOM Reperfusion Catheters and Aspiration Tubing are both sterilized using validated EO processes with a sterility assurance level of 1x106 The sterilization processes were validated per the overkill method described in recognized consensus standard ISO 11135, "Sterilization Of Health-Care Products - Ethylene Oxide - Requirements For The Development, Validation And Routine Control Of A Sterilization Process For Medical Devices." There were no changes to the ZOOM Reperfusion Catheters that would impact the validated EO process.

J. Shelf Life and Packaging:

Accelerated aging testing based on ASTM F1980 was previously conducted to verify packaged device performance. A minimum shelf life was established based on this testing and is indicated by the expiration date provided on the product labeling. There were no changes to packaging compared to the predicate ZOOM Reperfusion Catheters. In addition, there were no changes to the ZOOM Reperfusion Catheters that would impact the packaging validation.

K. Conclusions:

Where differences were identified between the subject ZOOM Reperfusion Catheters and predicate ZOOM Reperfusion Catheters, a risk assessment was completed to determine if the difference would result in new safety or effectiveness concerns. As appropriate, previous bench and laboratory testing was evaluated for applicability and either the

10

rationale for no impact was documented or verification and validation was repeated as required. As appropriate, bench and laboratory testing were conducted to support this assessment.

Based on the results of the risk assessments and associated bench and laboratory testing, the subject ZOOM Reperfusion Catheters and predicate ZOOM Reperfusion Catheters are substantially equivalent and there are no new safety or effectiveness concerns. The subject ZOOM Reperfusion Catheters and predicate ZOOM Reperfusion Catheters share the same intended use, basic technological characteristics, and equivalent performance characteristics.
