Mercy and Iowa Heart Center implant novel device to help lower high blood pressure

June 22, 2015

Des Moines, IA – June 22— Mercy Medical Center – Des Moines and Iowa Heart Center is one of seven centers in the U.S. conducting a study to evaluate a novel device to help lower high blood pressure. An Iowa Heart Center cardiologist was the first in Iowa to implant the device on May 6 at Mercy.

The CALM-FIM_US study is evaluating the MobiusHD device, a catheter-delivered implant permanently placed in the carotid artery of the neck. It is designed for patients with treatment-resistant high blood pressure, also known as resistant hypertension, which occurs when a person’s blood pressure remains high (160 mmHg or greater) despite taking at least three different medications to lower it. CALM is an abbreviation for “Controlling And Lowering Blood Pressure with the MobiusHD™” - a prospective multicenter safety study.

 “High blood pressure continues to grow in Iowa, the U.S. and worldwide,” said Iowa Heart Center cardiologist Magdi Ghali, M.D., and principal investigator of the trial at Mercy. “Despite advances in medical therapy, a growing number of patients suffer from drug resistance and this population has very few options available to regulate blood pressure once they have failed multiple medications.”

 The minimally invasive procedure uses a catheter the size of one typically used in a cardiovascular procedure. It is advanced through a small puncture in the groin and threaded into the carotid artery.

 Once there, the catheter delivers a metal implant into the carotid sinus, and the implant is designed to increase the signals generated by the surrounding arterial baroreceptors.  Baroreceptor nerve signals detect the pressure of blood flowing through them and send messages to the central nervous system to regulate blood pressure.  

 “Hypertension significantly increases risk of heart attack, stroke and kidney failure, so controlling it is vitally important,” said Dr. Ghali. “Mercy and Iowa Heart Center are excited to participate in this study and evaluate this device, as it may represent a life-changing treatment option for patients with resistant hypertension.”

The CALM-FIM_US study is sponsored by Vascular Dynamics, Inc. and is a prospective, open-label, multicenter, first-in-man trial.
