YPSILANTI (WWJ) – Integrated Sensing Systems Inc. announced that the United States Patent Office has granted it U.S. Patent No. 8,016,798 for “Fluid Delivery System and Sensing Unit.”

ISSYS, as company officials call the business, said the patent complements a related patent, No. 6,932,114, for “Fluid Delivery System and Method.”

ISSYS officials say the new patent describes a novel intravenous drug infusion system that employs micro-electro-mechanical systems Coriolis mass flow sensors to both control and monitor the delivery of one or more drugs to a patient on a tiny scale.

Medication errors have been reported to cause thousands of deaths and injuries in the U.S. each year and cost between $76 billion and $136 billion annually. Errors include improper dose, wrong medication, and excessive dose rate.

ISSYS successfully filed a 510(k) application with FDA for its first product (Model 405D: Drug Flow Monitor) which monitors the drug administration without pumping capabilities.  The model 405 product can greatly reduce the number of errors seen during drug delivery by monitoring multiple parameters including dose rate, total dose, bubbles in an IV line, occlusions, reverse drug or blood flow (called retrograde infusion) and administration of the wrong drug.

“Never before has a single product been able to provide the patient with so much protection,” said ISSYS CEO Nader Najafi.

Najafi said ISSYS plans to further develop its Model 405D to actively deliver drugs at high accuracies. This advanced drug delivery system will greatly improve the safety of intravenous drug delivery.

This patent reinforces the other ISSYS patents on the design, packaging, fabrication and application of microtube-based sensors, giving ISSYS comprehensive IP protection and offering a competitive barrier to market entry.

ISSYS designs and buildsn advanced MEMS technologies for industrial, medical, microfluidic and scientific analytical sensing applications. Founded in 1995, ISSYS is one of the oldest independent MEMS companies in the US. ISSYS operates a comprehensive, state-of-the-art MEMS fabrication plant in Washtenaw County.

ISSYS is currently registered to ISO 9001:2008, EN13980:2002 for its ATEX (intrinsically safe products), and ISO13485:2003 standard for Class III medical devices.
