Peelable sheath systems and methods for using peelable sheath systems are disclosed. The peelable sheath system may include an elongated tubular sleeve (e.g., a sheath) and a sleeve separation or removing device. The peelable sheath systems may also include a hub. The elongated tubular sleeve and the sleeve separation or removing device may be positioned about an elongated member of a medical device. Initially, the sleeve separation or removing device may be positioned on the elongated member of the medical device at a location at least partially proximal the elongated tubular sleeve. In operation, the sleeve separation or removing device may be advanced toward the elongated tubular sleeve to separate a portion of the tubular sleeve from another portion of the tubular and remove the tubular sleeve from about the medical device.
