About Us

PerSys Medical is a global provider of innovative solutions designed for military, hospital, law enforcement, first response, and emergency medicine personnel.

PerSys Medical was founded in Houston, Texas in 1988, initially operating under the name Performance Systems. The company provided a variety of marketing services to hi-tech companies attempting to penetrate the American marketplace. During its first ten years of operation, the company served over 100 corporate clients, bringing to market innovative products in a variety of fields including semi-conductors, software, telecommunication, and medicine. In 2003, the company narrowed its focus to the medical segment becoming a distributor for several manufacturing companies in the US and abroad. Most notably, PerSys introduced the Emergency Bandage, often called the “Israeli Bandage”, to the US Military. It has been a mainstay on the battlefield ever since.

In the decade following the introduction of the Emergency Bandage, PerSys centered its focus on Emergency Medicine and began to distribute multiple product lines to military, Law Enforcement, EMS, and Emergency Department personnel. The company began to build its own portfolio of medical devices by acquiring interest in the manufactures of its best-in-class product lines. By 2014, PerSys Medical became a majority stakeholder of Blizzard Protection Systems Ltd., Waismed Medical Ltd., and First Care Products Ltd., which solidified the company’s place in the market as well as their global reach.

Headquartered in Houston, Texas, PerSys Medical has a R&D center in Israel, manufacturing facilities in the US, UK, Israel and China, and sales offices around the world. Since its expansion, PerSys Medical has created a direct sales force as well as a distribution network for leading emergency medical products sold in over 60 countries worldwide. The company’s major products focus on hemorrhage control, intraosseous and vascular access, Hypothermia treatment, and airway management.
