Aphelion Capital, California Technology Ventures co-led the financing round and Research Corporation Technologies also participated in the round.

Clear Catheter Systems said it will use the capital to increase its PleuraFlow Active Tube Clearance System commercialization in the US and abroad.

Aphelion Capital’s Ned Scheetz said Clear Catheter’s Active Tube Clearance System’s technology aids in the post operative recovery from surgery.

"We believe Clear Catheter’s PlueraFlow system can improve hospital profitability by reducing the high costs associated with post surgical complications, and simultaneously improve patient care," Scheetz said.
