Swallow Solutions, a Madison, WI-based startup that develops therapeutic devices and other products for people with swallowing disorders, has raised more than $726,000 in new equity financing.

Seventeen investors participated in the funding round, according to an SEC filing. The company has raised nearly $4.9 million since launching in 2009, says Eric Horler, president and CEO of Swallow Solutions.

Horler says that his company plans to use most of the money raised in the latest funding round to continue developing thickened beverages for patients with dysphagia—a difficulty swallowing often caused by weak mouth and throat muscles—and other conditions.
