  • METHODS FOR INCREASING A RETENTION FORCE BETWEEN A POLYMERIC SCAFFOLD AND A DELIVERY BALLOON
    Publication number: 20240025083
    Abstract: A medical device includes a scaffold crimped to a catheter having an expansion balloon. The scaffold is crimped to the balloon by a process that includes inflating the delivery balloon during a diameter reduction to improve scaffold retention and maintaining an inflated balloon during the diameter reduction and prior and subsequent dwell periods.

  • Reducing crimping damage to a polymer scaffold
    Patent number: 9642729
    Abstract: A medical device includes a polymer scaffold crimped to a catheter having an expansion balloon. The scaffold is crimped to the catheter by a multi-step process for increasing scaffold-catheter yield following a crimping sequence. Damage reduction during a crimping sequence includes modifying blades of a crimper, adopting a multi-step crimping sequence, and inflating a supporting balloon to support the scaffold during crimping.
