Why just order the burger when you can get the combo? Biocompatibles International operates under a similar concept, developing technologies that combine medical devices and therapeutic drugs. Several of the company's products, such as its Bead Block, DC Bead, and LC Bead products, use proprietary polymer beads loaded with chemotherapy drugs to fight liver, colorectal, and other cancers. Its BrachySciences unit makes brachytherapy seeds, which deliver radiation for treatment of prostate cancer. Biocompatibles primarily sells through distribution agreements with companies including AngioDynamics (in the US) and Terumo Medical (Europe). The company was acquired by specialty pharmaceuticals company BTG in 2011.
