Campbell, California-based Imperative Care designed its Zoom Stroke solution for fast and effective clot removal. The system features the Zoom 88 large distal platform for neurovascular access, four-vessel-matched Zoom aspiration catheters, the Zoom Pump, Zoom POD and other accessories.
Data from an independent, single-center, multi-operator experience evaluating Zoom were presented by Dr. Collin Torok, neurointerventional surgeon at Midwest Radiology in Minneapolis-St. Paul, at the World Federation of Interventional and Therapeutic Neuroradiology (WFITN) 2022 Annual Meeting in Kyoto, according to a news release.
“The Zoom stroke solution is the only system that pairs an intracranial access catheter, Zoom 88, with a range of purposefully designed vessel-matching reperfusion catheters, Zoom 35, 45, 55 and 71, and pump that can help reach these types of occlusions and enable fast and effective clot ingestion,” Imperative Care President and COO Daniel Davis said in the release. “We look forward to continued studies to evaluate mechanical thrombectomy in these vessels and further emphasize the clinical efficacy of our technology.”
The study was undertaken to assess the safety and reperfusion success of aspiration thrombectomy in patients with these occlusions. Davis said that “more and more physicians” are opting to treat distal vessel occlusions despite their difficult-to-reach location in the brain.
Results demonstrated that TICI 2b/3 reperfusion was achieved in 92.7% (38/41) of patients and TICI 2c/3 reperfusion was achieved in 63.4% (26/41) of patients. Median time from access to first aspiration attempt was 10 (6.6 to 16.5) minutes and median time from access to final reperfusion was 21.5 (16.0 to 31.8) minutes.
Imperative Care reported one instance (2.4%) of symptomatic intracranial hemorrhage in this study cohort. There were no perforations or other reperfusion catheter-related complications.
“Distal vessel occlusions are considered the next frontier in mechanical thrombectomy for stroke treatment,” Torok said. “The data from this study offer additional clinical evidence that aspiration thrombectomy using the Zoom stroke solution is both safe and effective for occlusions in the MCA M2 segment. Furthermore, Zoom 88 provides an excellent intracranial access catheter platform for distal occlusions.
Even in the most tortuous cases, we have more than halved our procedural times with rapid initial and repeat passes to the distal circulation as needed.”
