Intended Use
The InThrill Thrombectomy System is indicated for: - The non-surgical removal of thrombi and emboli from blood vessels, including arteriovenous grafts for dialysis access, and synthetic grafts. - Injection, infusion, and/or aspiration of contrast media and other fluids into or from a blood vessel/graff. The InThrill Thrombectomy System is intended for use in the peripheral vasculature. The InThrill Thrombectomy System is not intended for use in deep vein thrombosis (DVT) treatment.
Device Description
The InThrill™ Thrombectomy System is a single-use, sterile medical device designed to remove thrombi and emboli from the peripheral vasculature. The InThrill™ Thrombectomy System consists of the InThrill Sheath ("Sheath") and the InThrill Thrombectomy Catheter ("Catheter"), each packaged separately. The Sheath is an introducer sheath with a distal self-expanding funnel, proximal aspiration port, and proximal hub. A Dilator is provided to aid insertion and positioning of the Sheath. Radiopaque markers aid Sheath positioning under fluoroscopic visualization. The Sheath and Dilator tips are radiopaque, and there is a radiopaque marker band at the proximal end of the Sheath funnel.
More Information

No
The provided text describes a mechanical thrombectomy system and its components. There is no mention of AI, ML, or any computational processing that would suggest the use of such technologies. The performance studies are focused on mechanical and simulated use testing.

Yes
The device is intended to remove thrombi and emboli from blood vessels, which directly treats a medical condition.

No

The device is indicated for the "non-surgical removal of thrombi and emboli from blood vessels," and for "injection, infusion, and/or aspiration of contrast media and other fluids." These are therapeutic or interventional actions, not diagnostic ones. While it mentions aiding "Sheath positioning under fluoroscopic visualization," this visualization is for guiding the therapeutic procedure, not for diagnosing a condition.

No

The device description explicitly states that the system consists of physical components: a sheath and a catheter, which are hardware.

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

Here's why:

  • IVD Definition: In Vitro Diagnostics are devices used to examine specimens (like blood, urine, or tissue) taken from the human body to provide information for diagnosis, monitoring, or screening.
  • Device Function: The InThrill Thrombectomy System is a mechanical device designed to physically remove thrombi and emboli from blood vessels. It is used within the body (in vivo) to treat a condition, not to analyze samples outside the body (in vitro).
  • Intended Use: The intended use clearly describes a therapeutic procedure (removal of thrombi and emboli) and the injection/aspiration of fluids within the blood vessel. This is not a diagnostic test performed on a specimen.

Therefore, the InThrill Thrombectomy System is a therapeutic medical device, not an In Vitro Diagnostic device.

  • Graft Leak Testing (Pre-Simulated Use) ●
  • In-Graft Simulated Use, InThrill Thrombectomy System ●
  • . Graft Leak Testing (Post-Simulated Use)
  • Graft Visual Inspection (Post-Simulated Use) ●
  • Radial Force Testing
  • Prescale Contact Paper Pressure Testing ●
  • Graft Abrasion Testing
  • Comparative Adherent Clot Removal Testing ●
  • Visual Inspection of Vein-to-Graft Anastomosis (Pre-Simulated Use)
  • Simulated Use, InThrill Catheter through Vein-to-Graft Anastomosis ●
  • Visual Inspection of Vein-to-Graft Anastomosis (Post-Simulated ● Use)

Test results demonstrated that all acceptance criteria were met; therefore, the device conforms to established product specifications.

Pre-Clinical Study

A GLP Animal study was performed, which did not identify any new questions of safety or effectiveness for the InThrill Thrombectomy System in peripheral vessels within the indicated size range.

Clinical testing was not required for the determination of substantial equivalence.

Conclusion

The non-clinical tests demonstrate that the subject device does not raise new questions of safety or effectiveness and, therefore, is substantially equivalent to the predicate device.
