Pacemaker longevity improved with engineered blood vessels

  • Comment

The creation of a new system of blood vessels engineered to interact with the tissue surrounding implanted devices, such as pacemakers, can increase their longevity researchers have found.

The University of Louisville led study explains how the body’s natural reaction to implanted devices is to form scars around them, recognising them as foreign.

Scars have little blood flow and the connection between the body and the device is compromised making it less effective over time. The new blood vessel system technique prevents this scar tissue forming.
