Fresh off his appearance on "The Tonight Show with Jimmy Fallon," a 15-year-old entrepreneur is back home in Snohomish, working on the company he started to market his inventions.

Suman Mulumudi traveled to New York last week to show Fallon how he turns a smartphone into a stethoscope. He also invented a device to help doctors clear blocked arteries.

He gets his ideas and support at home. Both his parents are doctors who work at The Everett Clinic.

The Daily Herald reports Mulumudi is a freshman at Lakeside School in Seattle.
