Publication number: 20190110914Abstract: A 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.Type: ApplicationFiled: December 12, 2018Publication date: April 18, 2019Inventors: Stephen D. Pacetti, Annie P. Liu, Mark C. Johnson
