OSI Systems Announces FDA Clearance for U.S. Sale and Distribution of Diagnostic Cardiology Data Management System

OSI Systems Announces FDA Clearance for U.S. Sale and Distribution of Diagnostic Cardiology Data Management SystemOSI Systems, Inc. (NASDAQ: OSIS - News), a vertically-integrated provider of specialized electronic products for critical applications in the Security and Healthcare industries, announced today that its Healthcare Division, Spacelabs Healthcare, has received 510(k) clearance from the U.S. Food and Drug Administration (FDA) to distribute in the U.S. its new Cardiology Data Management system, Sentinel.

Sentinel integrates the entire range of non-invasive diagnostic cardiology solutions including: ECG Exercise Testing, 12-Lead ECG, Holter Monitoring, ECG Event Recording and Ambulatory Blood Pressure Monitoring into one central data management system. The system enables a straightforward approach to consolidation and management of diagnostic cardiology procedures by centralizing all solutions in a central networked database that reduces the need for paper records, increases time saved in searching for patient details and improves workflow management.

The system has been designed for use either in a single station, such as within a physician's office, or as a fully scalable solution for large multi-centered hospitals. It is fully networkable and compatible with existing systems and third party vendor applications. Sentinel is also designed to integrate with existing hospital information systems allowing seamless connectivity of patient records from admission through recording, diagnosis and discharge. Patient reports can be viewed at workstations or via the web from any location through secured security software.

Deepak Chopra, Chairman and Chief Executive Officer of OSI Systems, stated, We are excited about achieving 510(k) clearance for Sentinel, our new Cardiology Data Management system, We believe that Sentinel provides physicians with an uncompromised facility to perform and to track the full range of diagnostic cardiology procedures from both internal and third party vendors applications.

The FDA requires that all medical devices introduced to the U.S. be preceded either by a pre-market notification clearance order under section 510(k) of the Food, Drug and Cosmetic Act, or an approved pre-market approval application.  A 510(k) pre-market notification clearance order indicates that the FDA agrees with an applicants determination that the product for which clearance has been sought is substantially equivalent to another legally marketed medical device.
