Sientra, a Santa Barbara medical device company focused on plastic surgery and aesthetics medicine, said it raised a $85 million second round of financing — one of the largest private funding rounds in the medical device sector.

Sientra also announced that it has acquired the assets of Silimed Inc., a leading developer of plastic surgery implants for both cosmetic and reconstructive surgery.

The round was co-led by OrbiMed Advisors and Clarus Ventures, and included Goldman Sachs and TIAA-CREF.

Sientra plans to use some of the proceeds to finance the Silimed acquisition.
