Inclusion of the first patient in the e-meuse study

September 2021

Biosency, Territoire Innovation winner, is participating in the first large-scale remote monitoring experiment for patients suffering from sleep apnea or COPD. For 3 and a half years, 400 patients will be monitored remotely in order to assess the benefit of treatment integrating connected objects in these chronic respiratory diseases.

Strategic partnership with ResMed

October 2022

A new major step in our development has been reached with the signing of a strategic partnership with ResMed, world leader in innovative solutions for the treatment of respiratory disorders. ResMed will thus distribute, in France, the Maghreb and certain European countries, our Bora care® remote monitoring solution, to healthcare professionals who care for patients suffering from respiratory failure.

Early detection of exacerbations

May 2023

During the prestigious international conference of the American Thoracic Society (ATS 2023) held in Washington, DC, Yann Le Guillou, co-founder of Biosency, revealed the results of his latest clinical study. These highlight the ability of our BVS3 technology to predict acute exacerbations of COPD (chronic obstructive pulmonary disease) on average 3 days before hospitalization in 86% cases, with only 9% false positives.

Obtaining MDR (Medical Device Regulation) certification

June 2023

This certification is proof of our dedication to meeting the strict standards and regulations set out under the European Medical Device Regulation and reinforces our commitment to ensuring the highest level of quality, safety and performance for our medical device, for the benefit of patients and healthcare professionals.
