  • SCAFFOLDS HAVING A RADIOPAQUE MARKER AND METHODS FOR ATTACHING A MARKER TO A SCAFFOLD
    Publication number: 20230038339
    Abstract: A scaffold includes a radiopaque marker connected to a strut. The marker is retained within the strut by a head at one or both ends. The marker is attached to the strut by a process that includes forming a rivet from a radiopaque bead and attaching the rivet to the marker including deforming the rivet to enhance resistance to dislodgement during crimping or balloon expansion. The strut has a thickness of about 100 microns.
    Type: Application

  • Protective sheaths for medical devices
    Patent number: 9913958
    Abstract: A process for making a sheath used to protect a medical device. The medical device includes a polymer scaffold crimped to a catheter having an expansion balloon. A sheath 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 is removed by a health professional either by removing the sheath directly or using a tube containing the catheter.
