Intended Use
The Trevo Retriever is intended to restore blood flow in the neurovasculature by removing thrombus in patients experiencing ischemic stroke 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.
Device Description
The Modified Trevo ProVue Retriever consists of a flexible, tapered core with a shaped section at the distal end. It is designed to restore blood flow in the neurovasculature by removing thrombus in patients experiencing ischemic stroke. A radiopaque coil at the distal end allows fluoroscopic visualization. The shaped section is also radiopaque. Retriever dimensions are indicated on the product label. The Retriever has a hydrophilic coating to reduce friction during use. A torque device and an insertion tool are provided with the Retriever. The proximal end of the device is compatible with the Abbott guide wire extension to facilitate removal or exchange of a catheter while maintaining the Retriever position in the vessel.
More Information

Not Found

No
The description focuses on the mechanical design and function of a medical device for thrombus removal, with no mention of AI or ML capabilities.

Yes
The device is intended to restore blood flow by removing thrombus in patients experiencing ischemic stroke, which is a direct therapeutic intervention to treat a medical condition.

No
The device is described as a "Trevo Retriever" which is intended to restore blood flow by removing thrombus, indicating a therapeutic function rather than a diagnostic one.

No

The device description clearly details a physical medical device (a retriever with a core, shaped section, radiopaque coil, coating, torque device, and insertion tool) intended for mechanical thrombus removal. It is not software-only.

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

Here's why:

  • Intended Use: The intended use is to "restore blood flow in the neurovasculature by removing thrombus in patients experiencing ischemic stroke." This is a therapeutic intervention performed directly on the patient's body.
  • Device Description: The device is a physical tool (a retriever) designed to be inserted into blood vessels to physically remove a clot.
  • Mechanism of Action: The device works by physically interacting with the thrombus within the blood vessel.
  • Lack of Diagnostic Function: There is no mention of this device being used to analyze samples (like blood, tissue, etc.) to provide diagnostic information about a patient's condition.

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.

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

Simulated Use -- Deliverability, Deployment, and Reloadability: Simulated use testing used a silicone neurovascular model cast from actual human neurovascular arteries. This bench testing model replicates the tortuosity, diameter and location of the arteries in the neurovasculature including the internal carotid artery (ICA) siphon. The model ends at the mid carotid arteries and proximal support is provided by a guide catheter. The model incorporates a re-circulating water bath at 37°C pressurized between 2 - 2.5 psi (100 - 126 mm Hg) to simulate the human arterial circulation. All testing follows the procedural instructions outlined in the Instructions for Use. Simulated thrombus is used to assess the devices ability to retrieve clot.
Results: All samples passed the acceptance criteria. Device continues to meet same design requirements as predicate device K122478.

Dear Ms. Meyer:

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. 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.
