Abstract
A method of forming a medical device or components thereof, including the steps of providing a first component of said medical device which is formed a first material and providing a second polymeric material into a mold cavity to overmold a second component of the medical device over the first component, and wherein the second polymeric material is further injected with a blowing agent to form a foam, and to components and to the medical devices made therefrom.
