Corewell Health treats first patient with radial access platform for stroke thrombectomy

January 25, 2023

GRAND RAPIDS, Mich., Jan. 25, 2023 — Corewell Health West, formerly Spectrum Health, has successfully completed the first-ever ischemic stroke case using the Zoom™ RDL Radial Access System. Zoom RDL provides a new option for accessing and removing life-threatening clots that cut off blood flow to a patient’s brain.

The surgery using Zoom RDL was successfully performed by Justin Singer, MD, director of vascular neurosurgery, Corewell Health West. It was the first of its kind in the U.S.

“Corewell Health West continues to be a leader in stroke care in West Michigan. This is one more way we are providing the latest in innovative treatments and approaches to improve patient care,” Singer said. “Accessing a blood clot through the radial artery in the wrist, as opposed to the femoral artery in the upper thigh, is preferable for certain patients and may result in easier recovery at the access site.”

Stroke occurs when a blood vessel feeding the brain gets clogged or bursts, cutting off vital blood flow to the brain. It is the fifth-leading cause of death in the U.S. and a major cause of serious disability among adults, according to the American Stroke Association. Most strokes are ischemic, meaning they involve a blocked vessel. Treatment of ischemic stroke may include a mechanical thrombectomy, a procedure that removes blood clots from the brain.

The Zoom RDL Radial Access System was developed by Silicon Valley-based Imperative Care®. Corewell Health Butterworth Hospital is the first hospital in the United States to utilize the platform, which recently received U.S. Food and Drug Administration (FDA) 510(k) clearance.

About Zoom RDL

Imperative Care’s Zoom RDL features an extended hydrophilic coating and the largest optimized vessel dilator on the market, providing a smooth introduction into the radial artery. Similar to the company’s FDA-cleared Zoom 88 LDP for femoral access, Zoom RDL features a large .088” lumen for compatibility with large-bore aspiration catheters. With an engineered support profile designed to reach the intracranial internal carotid artery (ICA), physicians can get higher into the brain and closer to the stroke-causing clot, giving them more control over the mechanical thrombectomy procedure.
