Intended Use
1. The Trevo Retriever is indicated for use to restore blood flow in the neurovasculature by removing thrombus for the treatment of acute ischemic stroke to reduce disability in patients with a persistent, proximal anterior circulation, large vessel occlusion, and smaller core infarcts who have first received intravenous tissue plasminogen activator (IV t-PA). Endovascular therapy with the device should start within 6 hours of symptom onset. 2. 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. 3. The Trevo Retriever is indicated for use to restore blood flow in the neurovasculature by removing thrombus for the treatment of acute ischemic stroke to reduce disability in patients with a persistent, proximal anterior circulation, large vessel occlusion of the internal carotid artery (ICA) or middle cerebral artery (MCA)-MI segments with smaller core infarcts (0-50 cc for age < 80 years, 0-20 cc for age ≥ 80 years). Endovascular therapy with the device should start within 6-24 hours of time last seen well in patients who are ineligible for intravenous tissue plasminogen activator (IV t-PA) or who fail IV t-PA therapy.
Device Description
The Trevo Retriever consists of a flexible, tapered core wire with a shaped section at the distal end. Platinum markers at the distal end allow fluoroscopic visualization. In addition, the shaped section is also radiopaque. Retriever dimensions are indicated on product label. The Retriever delivery wire has a hydrophilic coating on the distal 101cm length to reduce friction during use. The Retriever has a shaft marker to indicate proximity of Retriever tip relative to Microcatheter tip. A Torque Device is provided with the Retriever to facilitate manipulation and retrieval. The Retriever comes preloaded in an insertion tool to introduce the Retriever into a Microcatheter.
More Information

Not Found

No
The provided text describes a mechanical device for clot retrieval and does not mention any software, algorithms, or data processing that would indicate the use of AI or ML.

Yes
The device is used to restore blood flow in the neurovasculature by removing thrombus for the treatment of acute ischemic stroke, which directly treats a medical condition.

No

This device, the Trevo Retriever, is a medical device designed for the treatment of acute ischemic stroke by physically removing blood clots (thrombus) to restore blood flow. Its function is therapeutic, not diagnostic.

No

The device description clearly outlines physical components like a core wire, shaped section, platinum markers, hydrophilic coating, shaft marker, and a torque device. This indicates it is a hardware device, not software-only.

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

Here's why:

  • IVD Definition: In Vitro Diagnostics are devices intended for use in the examination of specimens derived from the human body (such as blood, urine, or tissue) to provide information for diagnostic, monitoring, or compatibility purposes.
  • Trevo Retriever's Intended Use: The Trevo Retriever is a medical device used within the body (in vivo) to physically remove blood clots from the neurovasculature. It is a therapeutic device, not a diagnostic one that analyzes samples outside the body.
  • Device Description: The description details a physical device designed for insertion and manipulation within blood vessels.
  • Input Imaging Modality: Fluoroscopic visualization is used to guide the device during the procedure, not to analyze a specimen.
  • Anatomical Site: The device operates within the neurovasculature, which is inside the body.

Therefore, the Trevo Retriever is a therapeutic medical device used for the treatment of acute ischemic stroke, not an IVD.
