About Christopher Potter

Canker Sores ("Aphthous Stomatitis") afflict about 20% of the population. The most common OTC treatments utilize benzocaine gels and ointments. The proposed device treats canker sores through the temporary application of a vacuum to an area encompassing a canker sore without the drawbacks associated with benzocaine (bitter taste, burning sensation, spill-over beyond the ulcer, and allergic reactions). In limited testing, the device successfully provided temporary pain relief while increasing blood flow at the affected areas. The global market for mouth ulcer treatments is estimated to be over $1.5B by 2020.

Technology Overview

The mechanism of action involves the application of negative pressure wound therapy (“NPWT”). Delivering a sustained vacuum to the wound site for a brief period may significantly accelerate the healing process in addition to providing pain relief. The application of a vacuum to the area of a canker sore provides the following benefits: improved blood flow for accelerated healing (granulation tissue) as well as temporary pain relief. I envision a manual or electronic suction device configured as a hand-held consumer device comprised of 3 basic elements: a vacuum mechanism, a conduit, and an applicator tip encompassing the ulcer. Guidance from the FDA anticipates this will be a Class 1 consumer medical device, but a PMA is required as no predicate device currently exists.
