Miramar Labs (no Web site), a Menlo Park, Calif., medical-device maker, raised $20.3 million in a second funding round, I’ve learned. There isn’t a huge amount of public information about the company, although it appears that the company is working on electromechanical devices of some sort for “aesthetic indications” — cosmetic surgery, in short.

Investors in the round included Split Rock Partners, Morgenthaler Partners and Domain Partners.
