Active Life Scientific, a six-year-old medical device company that develops biopsy technology, has raised $500,000 in a round of financing, the Santa Barbara-based firm said May 16.

The Series A round was filled by new and existing investors, and it included an investment by Tech Coast Angels, the largest angel investor network in the U.S. and one of the biggest sources of funding for startup companies in Southern California.

Active Life says its medical tool, which is called Reference Point Indentation, directly measures the physical properties of tissue inside a living body in the least invasive way possible. According to a news release, the firm’s technology was created to address the growing problem of degenerating and stiffening tissues, a leading cause of frailty.

“Modern medicine is successfully extending the duration of life to new levels. At Active Life, we are focused on extending and improving quality of life,” CEO Davis Brimer said in the news release. “We are honored to pursue this goal with the support of top-notch, sophisticated investors.”
