BMS Receives Funding For Continuing Expansion

Warwick, R.I.-based Biomedical Structures LLC (BMS) — a supplier of custom-designed biomedical
textiles for orthopedic, cardiovascular, general and reconstructive surgery, tissue engineering and
regenerative medicine, among other advanced clinical applications — has received financing from
Boston-based private equity firm Ampersand Ventures to support expansion of its services and
further development of technologies and cutting-edge materials.

BMS, established in 2003 as an independent, privately held company, designs and manufactures
crafted, nonwoven fibers and biomaterials, partnering with device companies to develop prototypes,
and eventually acting as contract manufacturer for final end products, which include a variety of
510(k) approved, implantable devices, components for surgical procedures and drug delivery tools.

“The Ampersand investment comes at a critical time in our company’s development when we are
seeing increased demand for our expanding portfolio of products and services,” said John Gray,
president, BMS. “The additional resources will enable us to grow even faster with new personnel,
more advanced equipment, and increased manufacturing capacity. Ampersand’s investment validates the
growth strategy that we have been implementing since our inception, and allows us to focus intently
on providing a distinct set of services to our customers.”
