ABOUT SUMMA

Our Mission is to develop simple, improved percutaneous transluminal angioplasty (PTA) technologies that improve the safety and economics of leg revascularization procedures.

Summa’s novel angioplasty balloon facilitates angioplasty procedures, allowing the procedure to be done with fewer steps and less equipment, which saves time, radiation to the patient and operator, and contrast dose to the patient.

There are two issued patents and FDA 510(k) clearance for marketing in the U.S.
