A delivery sheath is provided that that can be used to deliver a therapeutic device to the heart without dislodging the device when the delivery sheath is removed. The delivery sheath comprises a tubular body having a proximal end, a distal end, and a lumen. The therapeutic device is delivered through the lumen. A slit is provided along the length of the tubular body creating two opposing edges along the length of the tubular body. A guide wire engages along an entire length of the slit and closing the two opposing edges to form the lumen. The slit is opened from the distal end of the tubular body toward the proximal end of the tubular body by pulling on the guide wire at the proximal end, whereby the lumen expands and separates from the therapeutic device facilitating the extraction of the delivery sheath without disruption to the implanted device.
