Explant analysis : be part of our collaborative program

The GEPROVAS collects and analyzes explanted cardiovascular devices. We offer a unique and multidisciplinary approach to manufacturers, surgeons, learned society.

The goal is to establish a unique and multi-brand database of explants, complicated or not, by bringing our clinical and textile expertise to the analysis of their aging and degradation following their explantation.









Thus, GEPROVAS is a fundamental player in improving patient care.
