ANGO

Angiodynamics, Inc.

A maker of medical devices for treating cardiovascular disease and cancer, AngioDynamics builds tools like the NanoKnife ablation system, the Auryon atherectomy device, and the VenaCure laser for varicose veins, used by interventional radiologists, cardiologists, and vascular surgeons. It began in 1988 as a division of E-Z-EM, a company known for imaging contrast agents, and its name blends "angio" (blood vessels) with "dynamics." Its NanoKnife system, which uses electrical pulses rather than heat to destroy prostate tumors, was named one of TIME's Best Inventions of 2025.
