Key Insights
Imperative Care (search)'s Zoom System (search), a comprehensive stroke (search) thrombectomy (search) system, has received FDA 510(k) clearance, expanding its portfolio of aspiration catheters.
The Zoom System (search) includes large-bore 0.088-inch catheters indicated for both access and aspiration, offering versatility for rapid and effective stroke (search) procedures.
Clinical trial data demonstrated a median time of 19 minutes from groin puncture to successful reperfusion (mTICI ≥ 2B), the fastest among referenced trials.
Imperative Care (search), Inc. has announced FDA 510(k) clearance for its Zoom System (search), a comprehensive stroke (search) thrombectomy (search) system featuring large-bore 0.088-inch catheters. This clearance allows for both access and aspiration when used with a Zoom catheter, marking a significant advancement in stroke treatment options. The system's efficacy and safety were validated in the Imperative Trial, a prospective, multi-center study conducted across 26 U.S. institutions.
The Zoom System (search) expands Imperative Care (search)'s existing portfolio of 0.035- to 0.071-inch aspiration catheters, now including the Zoom 88, Zoom 88 Support, and TracStar catheters. These are designed for aspiration as part of the Zoom system.
Clinical Trial Results
The Imperative Trial, which supported the FDA clearance, involved 211 patients treated with concomitant aspiration thrombectomy (search) using two catheters. Key findings include:
- A median time of 19 minutes from groin puncture to mTICI ≥ 2B reperfusion, the fastest among referenced thrombectomy trials.
- An 84% rate of mTICI ≥ 2B reperfusion achieved within three passes or less without additional thrombectomy devices.
- Stent retriever rescue therapy was required in only 4.7% of cases to achieve mTICI ≥ 2B reperfusion.
- A core-lab adjudicated rate of symptomatic intracranial hemorrhage of 0.9%, lower than previous trials (4.7%).
- A rate of independently adjudicated dissection and vessel perforation of 0.5%, also lower than previous trials (1.3%).
Expert Commentary
Dr. William Mack, Professor of Neurosurgery at the Keck School of Medicine, University of Southern California, and Co-Principal Investigator of the Imperative Trial, commented on the system's safety profile: "In addition to the remarkable efficacy of the Zoom system (search), I was impressed by the demonstrated safety profile as evidenced by a 0.5% instance of serious vessel injury reported in the study. Even more impressive was the 0.9% rate of symptomatic intracranial hemorrhage (search). These data, combined with our extensive experience with the Zoom system, reinforce our confidence in the technology and its clinical benefits for our practice and the patients we treat."
