Water Street Healthcare Partners, a health care private equity firm, has acquired Massachusetts-based Medical Specialties Distributors (MSD), a provider of infusion disposable products, supplies, biomedical services and technology solutions to the home infusion therapy market. The acquisition expands Water Street's current group of health care companies to 12.

Massachusetts-based MSD offers customers a full range of infusion equipment and disposable supplies, as well as comprehensive services that encompass biomedical rental and repairs, equipment management and tracking, and formulary development.

Jim Beck, president and CEO of MSD, will continue to lead the company and its current management team. He will work closely with Water Street’s team, which includes former executives of global distribution businesses such as American Hospital Supply Corp, Baxter International and McKesson.

Mr Beck said: “Water Street is the ideal partner to help MSD advance our services and capabilities to provide greater value to our customers in this growing market. I have known its partners for many years and believe they have an unmatched level of expertise building and operating specialty distribution businesses.

“MSD will benefit from Water Street’s expertise and ideas for how we can expand our services to the growing number of infusion centers and oncology clinics that are treating patients in the home.”

Water Street firm’s companies operate in a range of health care sectors including specialty distribution, medical devices and products, and specialty services. MSD is Water Street’s third investment in the medical distribution sector.
