Abstract
Abstract A delivery system for a medical device or other devices to be deployed within a biological body including a sheath having a longitudinal joint. The joint can be either resealable or non-resealable. The joint remains intact during delivery of the medical device, thereby facilitating accurate delivery of the medical device. During removal of the sheath, the joint is separated, thereby permitting the sheath to be peeled from the medical device while maintaining the position of the device. The delivery system allows a single operator to deploy the medical device and remove the sheath.
