Yes.
The device is indicated for use in the revascularization of patients with acute ischemic stroke secondary to intracranial large vessel occlusive disease by facilitating the removal of thrombus/clot, which is a direct treatment for a medical condition.
No
The device is indicated for revascularization and removal of thrombus/clot, which are therapeutic actions, not diagnostic.
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:
- Intended Use: The intended use is for the revascularization of patients with acute ischemic stroke by physically removing thrombus/clot from blood vessels. This is a therapeutic intervention performed directly on the patient's body.
- Device Description: The device is a catheter system designed to be inserted into blood vessels and used with a vacuum source to aspirate clots. This is a medical device used for treatment, not for analyzing samples outside the body.
- Lack of IVD Characteristics: There is no mention of analyzing biological samples (blood, urine, tissue, etc.) in vitro (outside the body) to provide diagnostic information. The device's function is purely mechanical/physical.
IVD devices are used to examine specimens derived from the human body to provide information for diagnostic, monitoring, or compatibility purposes. This device does not fit that description.

Intended Use / Indications for 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 ZOOMTM 71 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 71 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 71 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 71 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 comprised of a hollow cylindrical tube which is bonded to a standard luer fitting that connects to the ZOOM 71 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.
In addition to the accessories discussed above, the adjunctive devices and supplies listed below are intended to be used with the ZOOM 71 Reperfusion Catheter and Aspiration Tubing.

G. Performance Data Supporting Substantial Equivalence:
Bench testing was completed to evaluate the differences between the subject ZOOM 71 Reperfusion Catheter and predicate ZOOM 71 Reperfusion Catheter. Performance specifications and test methods were based primarily on catheter performance standard ISO 10555-1 and a summary of the evaluated performance specifications is presented in Table 4 below.
8
The test results were reviewed and found to demonstrate that the differences between the subject ZOOM 71 Reperfusion Catheter and predicate ZOOM 71 Reperfusion Catheter do not significantly impact any performance parameters that would negatively affect the safety or effectiveness of the subject ZOOM 71 Reperfusion Catheter.
| Test Attribute | Specification |
|---|---|
| Dimensional(Distal OD, Distal ID) | All defined catheter dimensions are within the specified tolerances. |
| Catheter Bond Strength | The catheter shall have sufficient bond strengths to remain intact throughout a procedure. |
| Kink Resistance | There shall be no kinking of the catheter shaft (permanent deformation) at anatomically relevant bend radii. |
| Tip Flexibility | The flexibility of the catheter tip shall be comparable to competitive products and allow for easily tracking the device to the desired target anatomy. |
| Freedom from Leakage - Positive Pressure | No liquid leakage from the hub or catheter shaft at 46psi for 30 seconds |
| Freedom from Leakage - Negative Pressure | No air leakage into a 20cc syringe when vacuum pulled for 15 seconds. |
Table 4: Tests and Performance Specifications for ZOOM 71 Reperfusion Catheter
There were no changes to the ZOOM Aspiration Tubing or ZOOM Aspiration Pump and no changes to the subject and predicate ZOOM 71 Reperfusion Catheter 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, testing in support of the predicate device applies to the subject device and additional biocompatibility testing was not required.
I. Sterilization:
The ZOOM 71 Reperfusion Catheter and Aspiration Tubing are both sterilized using validated Ethylene Oxide (EO) processes with a sterility assurance level of 1x106. The sterilization processes were validated per the overkill method described in the recognized consensus standard ISO 11135, "Sterilization Of Health-Care
9
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 71 Reperfusion Catheter 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 71 Reperfusion Catheter. In addition, there were no changes to the ZOOM 71 Reperfusion Catheter that would impact the packaging validation.
K. Conclusions:
Where differences were identified between the subject ZOOM 71 Reperfusion Catheter and predicate ZOOM 71 Reperfusion Catheter, 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 were evaluated for applicability and either the rationale for no impact was documented or verification and validation was repeated as required. The results of design verification and validation did not raise different questions of safety and effectiveness.
Based on the results of the risk assessments and associated bench and laboratory testing, the subject ZOOM 71 Reperfusion Catheter and predicate ZOOM 71 Reperfusion Catheter are substantially equivalent and there are no new safety or effectiveness concerns. The subject ZOOM 71 Reperfusion Catheter and predicate ZOOM 71 Reperfusion Catheter share the same intended use, basic technological characteristics, and equivalent performance characteristics.
