ClotBust-ER study to evaluate stroke therapy and investigational ultrasound device

RENO, Nev. – Monday, Jan. 26, 2015 – Saint Mary's Center for Neurovascular and Stroke Care is the only stroke center in the state of Nevada testing an investigational approach for treatment of acute ischemic stroke in an emergency room setting. The ClotBust-ER could present a faster, more efficient way for treating ischemic stroke patients by using ultrasound to break up blood clots in the brain and restoring blood flow, thus improving patient outcomes.

"There is a need for new treatment approaches to improve the outcomes of patients that are affected by the devastating effects of ischemic stroke," said Aaron Heide, MD, director of Saint Mary's telemedicine and stroke services. "There have been few advances for the treatment of ischemic stroke since tPA was approved in 1996. If validated in this Phase 3 clinical study, ClotBust-ER could potentially provide clinicians with a new treatment option."

Stroke is the third leading cause of death in the U.S. and the leading cause of serious long-term disability. An ischemic stroke is a type of stroke that occurs due to a blocked artery caused by a blood clot or the gradual build-up of plaque or other fatty deposits and approximately 87 percent of all strokes are ischemic.

ClotBust-ER is a first-in-class device used to quickly and easily deliver ultrasound energy to the proper regions of the brain for treatment of ischemic stroke. The device is in the shape of a head frame that is placed on the patient, similar to a pair of eyeglasses. It delivers ultrasound energy to the region of the occluded vessel in the brain. The device is non-invasive, painless and has no serious side effects.

Saint Mary's is participating in the worldwide Phase 3 clinical trial designed to evaluate if the combination of ClotBust-ER with standard stroke treatment improves recovery outcomes for patients. The goal of the device is to help minimize the damage to the brain that occurs during an acute stroke, meaning the level of long-term debility patients suffer is lessened. Patients suffering from an acute ischemic stroke may be offered this technology to increase their chances of recovery. Saint Mary's is one of 60 leading stroke centers in 14 countries worldwide participating in this study.

"We are proud to be involved in the latest cutting edge research to help improve outcomes for our stroke patients," said Heather Schofield, RN, BSN, Saint Mary's stroke program coordinator. "Being a part of this study means being on the frontline of medical advancement and technological development."
