The provided text describes a mechanical system for clot removal in stroke patients and does not mention any AI or ML components.
Yes
The devices are indicated for the revascularization of patients with acute ischemic stroke secondary to intracranial large vessel occlusive disease, which is a medical condition, making them therapeutic.
No
The device is indicated for revascularization and thrombus removal in patients with acute ischemic stroke, which are therapeutic interventions, not diagnostic ones.
No
The device description clearly outlines physical components like catheters, separators, tubing, and a pump, which are hardware. The mechanism of action involves aspiration, a physical process.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections. They are used to provide information for diagnosis, monitoring, or screening.
- Device Function: The description clearly states that the Penumbra System, including the 3D Revascularization Device, is used for the revascularization of patients with acute ischemic stroke. This involves physically removing blood clots from arteries within the brain.
- Mechanism of Action: The mechanism of action is described as aspiration, which is a physical process of drawing out the clot.
- Intended Use: The intended use is to treat a medical condition by intervening directly within the patient's body.
The device is an interventional medical device used for treating a stroke, not for diagnosing or monitoring a condition through analysis of samples outside the body.

Device Description
The Penumbra System 3D Revascularization Device is designed to revascularize patients experiencing acute ischemic stroke as a component of the Penumbra System. The Penumbra System's fundamental mechanism of action is aspiration removes clot by drawing it into the Penumbra Reperfusion Catheter. The 3D Revascularization Device is designed to assist the Reperfusion Catheter with thrombus removal if needed. Intended users for this device are physicians who have received appropriate training in interventional neuro-endovascular techniques and treatment of acute ischemic stroke. The device is provided sterile, non-pyrogenic, and intended for single use only.

Dear Michaela Mahl:
This letter corrects our substantially equivalent letter of April 26, 2019.
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal
1
statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting of medical device-related adverse events) (21 CFR 803) for devices or postmarketing safety reporting (21 CFR 4, Subpart B) for combination products (see https://www.fda.gov/CombinationProducts/GuidanceRegulatoryInformation/ucm597488.html; good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.
