TYRX, Inc., the leader in the commercialization of implantable medical devices designed to help reduce surgical-site infections associated with implantable devices including pacemakers and defibrillators, announced today it has received a private investment from the California-based MemorialCare Innovation Fund (MCIF). MCIF is a strategic investment company wholly owned by MemorialCare Health System.

"MemorialCare is a leading healthcare system and its investment is a strong validation of TYRX's products and our ability to improve outcomes for hospitals, physicians and patients," stated Robert White, TYRX's President and CEO. TYRX has already achieved a number of key milestones in 2013 including:
¢
Successfully implanted the AIGISRx device in over 35,000 patients.
¢
The Journal of Pacing and Clinical Electrophysiology (PACE) published the results of a large study conducted by Vanderbilt Heart and Vascular on patients at high risk for pacemaker and implantable cardioverter defibrillator (ICD) infection with ‰¥ 2 pre-identified risk factors. After a minimum of 90-days of follow-up, the incidence of CIED infection was 87% lower in the group that received a TYRX AIGISRx Antibacterial Envelope (0.4% vs. 3.0%, p=0.04).
¢
Dr. Charles Henrikson, the Chief of Electrophysiology at the Oregon Health Sciences University, presented an interim analysis on 1,000 patients from the CITADEL / CENTURION studies during the Heart Rhythm 2013 Late Breaking Clinical Trials session showing 95% fewer major infections after 3 months in patients undergoing pacemaker and ICD replacement procedures using the AIGISRx compared to similar published high-risk cohorts who did not receive the envelope (0.1% vs. 1.88%, p<0.001).
¢
Dr. Suneet Mittal and his colleagues from the Arrhythmia Institute, Valley Health System, and Columbia University College of Physicians & Surgeons presented the results of their study at Heart Rhythm 2013 showing that AIGISRx significantly reduced cardiac device infection rates. In propensity score matched cohorts there were 70% fewer infections in the cohort with the AIGISRx (1.1% vs. 3.6%; p=0.048).
¢
Approval received for the next generation AIGISRx R Fully Resorbable Antibacterial Envelope from Health Canada.
TYRX's portfolio of AIGISRx Antibacterial Products is specifically designed to aid in the stabilization of pacemakers and ICD's, as well as to help reduce surgical-site infections.

Patients who contract surgical-site infections, following cardiac device procedures, spend an average of two extra weeks in the hospital, undergo repeat surgical procedures to treat the infection, and cost the facility an average of $72,485. Additionally, such patients experience significant increases in morbidity and mortality, with 1-year mortality rates of up to 35%, and 3-year mortality rates of up to 50%, depending on device type. Based on the clinical and economic evidence developed to date, hospitals are able to save over $1,000 per patient when using the AIGISRx Antibacterial Envelope on high risk patients.*

"We are looking forward to our partnership with Clarus Ventures, Pappas Ventures and HLM Venture Partners to assist TYRX in pursuing technology that is critical to improving clinical and economic outcomes for hospitals." said Brant Heise, Managing Director, MemorialCare Innovation Fund. "Preventing surgical site infections helps ensure better patient outcomes while reducing the cost of care. All hospitals understand the importance of reducing the incidence of infection, and we are supportive of the role TYRX's technology will play in this endeavor."
