Medical device fixation

This invention describes a way to securely attach a small electronic medical device inside a patient's blood vessel. It uses two methods: a temporary, dissolvable part, like a biodegradable stent, that holds it in place initially, and a permanent part that encourages the body's own tissue to grow around it, securing it long-term as the temporary part disappears. The claims specifically describe using a biodegradable stent to push the device against the blood vessel wall.
