Imperative Care Evaluates Zoom Stroke Solution for MCA M2 Occlusions in Single-Center Study

August 24, 2022—Imperative Care, Inc. announced that new data were presented evaluating its Zoom stroke solution for treatment of patients with middle cerebral artery (MCA) M2 occlusions. The data were presented by Collin Torok, MD, at the World Federation of Interventional and Therapeutic Neuroradiology annual meeting held August 21-25 in Kyoto, Japan.

According to the company, the single-center, multioperator experience was undertaken to assess the safety and reperfusion success of aspiration thrombectomy in patients with distal vessel occlusions.

As noted in the press release, the study findings are as follows:

• Thrombolysis in cerebral infarction (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).
• The median National Institutes of Health Stroke Scale score decreased from 10.5 (IQR, 7.0 to 14.5) at arrival to 1.5 (IQR, 0 to 6.0) at discharge, P < .001.
• The median time from access to first aspiration attempt was 10 minutes (6.6 to 16.5 minutes), and the median time from access to final reperfusion was 21.5 minutes (16.0 to 31.8 minutes).
• There was one instance (2.4%) of symptomatic intracranial hemorrhage.
• There were no perforations or other reperfusion catheter-related complications.

“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,” said lead author Dr. Torok. “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.” Dr. Torok is a neurointerventional surgeon at Midwest Radiology in Minneapolis-St. Paul, Minnesota.

Daniel Davis, President and COO of Imperative Care, explained in the announcement that the Zoom stroke solution system pairs Zoom 88, an intracranial access catheter, with a range of vessel-matching reperfusion catheters (Zoom 35, 45, 55, and 71) and the Zoom pump to reach occlusions and enable fast, effective clot ingestion.

He further remarked, “We look forward to continued studies to evaluate mechanical thrombectomy in these vessels and further emphasize the clinical efficacy of our technology.”
