DURHAM – Physcient Inc., a Durham-based medical device company developing a dissector that differentiates between tissue types in a variety of surgeries, has raised $134,000 of a $1 million debt offering, according to a filing with the U.S. Securities and Exchange Commission.

Founded in 2007, the company’s surgical tools reduce tissue damage in laparosopic, thoracic, endoscopic, plastic and general surgery.  

It raised $2.2 million in equity investments and more than $1.5 million in debt offerings since 2011.

The company’s Differential Dissector is the first instrument that automatically differentiates between tissue types. The single-use instrument is handheld and battery-powered.

Surgeons have used the device successfully in multiple preclinical, clinical and cadaver procedures. The live surgeries were nearly bloodless due to the instrument’s ability to preserve even tiny blood vessels.
