Abstract
A delivery catheter includes a constraining sheath coupled to a distal end of the catheter, and a medical device, such as an embolic protection device (EPD) or a stent, constrained by the sheath. A wire may extend proximally from the constraining sheath and be coupled thereto. A proximal pulling force on the wire causes the wire to tear the constraining sheath, thereby releasing the medical device from a constrained configuration to an expanded configuration.
