About Gradient Denervation Technologies
We’re redefining treatment for pulmonary hypertension with next-generation PADN technology.

Gradient Denervation Technologies is a Paris-based medical device company developing a breakthrough treatment for pulmonary hypertension (PH). Our aim is to offer a minimally invasive therapy that uses a targeted approach to ease pressure in the lungs and heart for patients with certain types of pulmonary hypertension.
Built on technology developed at Stanford University, Gradient is initially dedicated to improving care for patients with Group 2 PH, particularly those affected by the more complex form known as CpcPH, a group with limited treatment options today.
