  • Patent number: 10232147
    Abstract: A medical device includes a polymer scaffold crimped to a catheter having an expansion balloon. A sheath pair is placed over the crimped scaffold after crimping to reduce recoil of the crimped polymer scaffold and maintain scaffold-balloon engagement relied on to hold the scaffold to the balloon when the scaffold is being delivered to a target in a body. The sheath pair is removed by a health professional before placing the scaffold within the body.

  • Publication number: 20180154051
    Abstract: The present disclosure teaches methods of controlling the release rate of agents from a polymeric matrix that include designing and creating a predetermined initial morphology (IM) profile in a polymeric matrix. The teachings indicate, inter alia, that control over the release rate of agents can provide for an improved control over the administration of agents as well as have an effect upon the mechanical integrity and absorption rate of the polymeric matrix.
