The summary describes a mechanical aspiration system for treating stroke and does not mention any AI or ML components.
Yes
The device is indicated for use in the revascularization of patients with acute intracranial large vessel occlusive disease, which is a direct therapeutic intervention to restore blood flow.
No
Explanation: The device is indicated for revascularization and treatment of intracranial large vessel occlusive disease, which is a therapeutic purpose, not diagnostic.
No
The device description clearly outlines physical components including catheters, tubing, and an on/off switch, 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 stroke due to intracranial large vessel occlusion. This is a therapeutic intervention performed in vivo (within the body) to treat a medical condition.
- Device Description: The device consists of catheters and tubing designed for aspiration and delivery within the vascular system. These are tools used for a medical procedure, not for analyzing samples in vitro (outside the body).
- Lack of IVD Characteristics: There is no mention of the device being used to test or analyze biological samples (like blood, urine, tissue, etc.) to provide diagnostic information. The device's function is to physically remove a clot.
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.
N/A
Intended Use / Indications for Use
The Route 92 Medical Full Length 070 Reperfusion System and Aspiration Tubing Set is 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 failed IV t-PA therapy are candidates for treatment.

Device Description
The Aspiration Catheter and Tenzing 7 Delivery Catheter comprise the Route 92 Medical Full Length 070 Reperfusion System. The Route 92 Medical Full Length 070 Reperfusion System is used with the Route 92 Medical Aspiration Tubing Set.
The Aspiration Catheter is a single-lumen, coil-reinforced variable stiffness catheter. The Tenzing 7 Delivery Catheter is a single-lumen variable stiffness catheters are hydrophilically coated. The devices are provided sterile and non-pyrogenic and are intended for single use only.
The Route 92 Medical Aspiration Tubing Set is made from high-pressure tubing. An on/off switch is provided to control fluid flow. A suction connector allows connection to an aspiration pump canister and a Luer fitting allows connection to the aspiration catheter.
For the aspiration source, the Aspiration Catheter is used in conjunction with an aspiration pump with prespecified performance parameters that is connected using the Route 92 Medical Aspiration Tubing Set, along with a legally marketed canister and accessories kit.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Non-Clinical Testing:
- Shelf Life and Sterility: The Reperfusion System and Aspiration Tubing are sterilized using an ethylene oxide sterilization cycle verified to a sterility assurance level of 1 x 10-6 in accordance with ISO 11135. Aging studies established that the subject device and packaging remain functional for the labeled expiration date. Aging studies for packaging integrity, seal strength, and device functionality were performed and met the acceptance criteria.
- Biocompatibility Testing: Patient-contacting materials of the Reperfusion System were unchanged from the K222743 Reference Device, so no additional biocompatibility testing was required for it. All patient-contacting components of the Aspiration Tubing were evaluated for biocompatibility in accordance with ISO 10993-1. It is a device with limited (≤24 hours) contact with intact skin.
- Cytotoxicity - ISO MEM Elution: The test article extract showed no evidence of causing cell lysis or toxicity and met requirements (grade less than 2), concluding it is non-cytotoxic.
- Sensitization - ISO Guinea Pig Maximization Sensitization Test (Normal Saline and Sesame Oil): The test article extracts showed no evidence of causing delayed dermal contact sensitization in the guinea pig, concluding it did not elicit a sensitization response.
- Irritation - ISO Intracutaneous Reactivity (Normal Saline and Sesame Oil): The test article met requirements, with the difference between test article extract overall mean score and control extract overall mean score being 1.0 or less for both sodium chloride and sesame oil extracts.

The Reperfusion System and Aspiration Tubing are sterilized using an ethylene oxide sterilization cycle that was verified to a sterility assurance level of 1 x 10-6 in accordance with ISO 11135. Aging studies established that the subject device and packaging remain functional for the labeled expiration date. Aging studies for packaging integrity, seal strength, and device functionality were performed and met the acceptance criteria.
Biocompatibility Testing
The patient-contacting materials of the Reperfusion System were unchanged compared to the K222743 Reference Device; therefore, no additional biocompatibility testing was required.
All patient-contacting components of the Aspiration Tubing were evaluated for biocompatibility in accordance with ISO 10993-1 Biological Evaluation of Medical Devices Part 1: Evaluation and Testing. Per ISO 10993-1, the Route 92 Medical Aspiration Tubing Set is a device that has limited (≤24 hours) contact with intact skin. A summary of the biocompatibility testing is provided below.

Animal Studies
Two chronic animal studies were conducted according to good laboratory practices (GLP) in a swine model to demonstrate the safety and performance of the Route 92 Medical Reperfusion System and to establish substantial equivalence to the Predicate Device. Study animals were terminated at either subacute (3-day) or chronic (30-day) time points. Devices were evaluated under worst-case clinical conditions, including soft and firm clot aspiration, wedge aspiration, downstream organ assessment, inlife observations, and postmortem assessment of relevant tissues (treated vessels, downstream vessels).
Substantial Equivalence
The Route 92 Medical Full Length 070 Reperfusion System and Aspiration Tubing Set has the same intended use, similar technological characteristics, and same method of action as the predicate device. Differences between the subject and predicate devices do not raise new questions of safety and effectiveness of the device. The successful completion of biocompatibility testing, bench performance testing, and animal testing demonstrates that the Route 92 Medical Full Length 070 Reperfusion System and Aspiration Tubing Set is substantially equivalent to the predicate device.
