Microsoft today announced its intention to acquire Sentillion, a privately held developer of healthcare software, for an undisclosed sum.

Redwood, Wash.-based Microsoft said it intends to combine Sentillion’s context management and single sign-on technologies with its Amalga Unified Intelligence System (UIS), a real-time data aggregation solution.

Both companies’ solutions aim to address the same challenges in healthcare—“integrating vast amounts of clinical, administrative and financial information that flow in and out of disparate information systems and tailoring that information for use by physicians, analysts, laboratory technicians, nurses and administrators.”

Sentillion said it will “continue to sell and support its products to new and existing customers while Microsoft invests in the long-term evolution of the combined portfolio of Sentillion and Microsoft health solutions.”

Sentillion also will continue to operate out of its corporate headquarters in Andover, Mass. The acquisition is expected to close in early 2010.
