Abstract
A sheath used to protect a medical device has one or more strips formed over a portion thereof. The medical device is a scaffold crimped to a balloon and mounted to a catheter. The sheath is two-piece, including a protecting and constraining sheath part. The strips facilitate removal of the constraining sheath from the scaffold in manner that reduces instances of damage caused by improper removal of the sheath from the medical device.
