ExoVasc® PEARS

ExoVasc® Personalised External Aortic Root Support (PEARS)

ExoVasc® PEARS

The ExoVasc® PEARS is a patient-led innovation in the form of an implant that is placed around the ascending aorta. It provides support to the patient’s own aorta and aortic valve and is designed to prevent aortic dilation, dissection and rupture.

Surgical centres

The procedure for implanting the ExoVasc® PEARS is offered in over 40 centres in the UK, Europe and the rest of the world. It is not currently available for sale in the USA.

Patient stories

More than 1,300 people have had an ExoVasc® PEARS implanted. Some of them have shared their stories and experiences before and after surgery. You can read their stories here.

About Exstent

The ExoVasc® PEARS was developed by Tal Golesworthy, an engineer with Marfan syndrome, to provide an alternative to aortic root replacement surgery. 

Exstent aims to make a difference to the lives of people with aortic dilation. Our goal is to allow patients to live free from worry, without need for anticoagulant therapy and reduce the risk of requiring further surgery.
