RenalGuard Clinical Data Presented at International Conference of the Israel Heart Society

MILFORD, MA--(Marketwired - May 07, 2013) - PLC Systems Inc. (OTCBB: PLCSF), a company focused on innovative medical device technologies, today announced that clinical results using RenalGuard Therapy® were reported by researchers from two Israeli hospitals at The 60th International Conference of the Israel Heart Society.

Dr. Eyal Ben-Assa of Tel Aviv Medical Center presented a poster reporting the results from 25 patients using RenalGuard® at his center.

Dr. Ben-Assa commented, "Our experience with RenalGuard, as reported in our paper, has been very positive. The incidence of CIN is much lower than would otherwise be expected and there was no need for dialysis among this very high risk patient population. Based on these results, RenalGuard has become the standard of care for at-risk patients at our center."

Also at the conference, Dr. Eyal Nacum of Sheeba Hospital in Petah Tikvah presented at a session entitled, "Incidence of Acute Kidney Injury in the Patients Undergoing Surgical TAVI". Dr. Nacum's presentation included reports of his initial experiences using RenalGuard in patients undergoing Surgical Transcatheter Aortic Valve Implantation (TAVI) to protect them from acute-kidney injury (AKI).

Mark R. Tauscher, President and CEO of PLC Medical commented, "Dr. Nacum's experience using RenalGuard in TAVI patients is an important contribution supporting the need to protect TAVI patients from AKI. TAVI is a large and growing market for RenalGuard. A number of clinical trials have shown that patients who undergo TAVI have significantly improved outcomes overall. It has also been reported that many TAVI patients develop AKI, and these patients go on to have increased mortality and longer hospital stays, thereby diminishing the benefits of the groundbreaking procedure. We believe that RenalGuard has the potential to protect TAVI patients from acute kidney injury and help them to enjoy the full benefits of the TAVI procedure." 

Transcatheter aortic valve implantation (TAVI) is a non-surgical method for replacing diseased aortic valves in patients where conventional open heart surgery is not an option. Until a few years ago, there were no therapeutic options for these patients. The procedure involves inserting a replacement valve into the heart where the failing valve is pushed out of the way and replaced. 

RenalGuard therapy is designed to rapidly remove contrast dyes that are potentially toxic to patients with impaired kidney function. Contrast dyes are used in many cardiovascular diagnostic and interventional imaging procedures to facilitate the capture and display of x-ray images. Approximately 10% to 20% of patients that undergo these procedures are at-risk of developing Contrast-Induced Nephropathy (CIN), a form of acute kidney injury resulting from toxic contrast dye. No other product on the market has been shown to consistently reduce the incidence of CIN. In two investigator-sponsored clinical trials, RenalGuard Therapy has reduced the incidence of acute renal failure. We believe that RenalGuard may help reduce morbidity and mortality, as well as hospital costs for the high-risk patients.
