Abstract
A perfusion guidewire is disclosed. The perfusion guidewire includes an elongate core member and a collapsible sheath tightly wrapped around at least the distal portion of the elongate core member such that the wrapped sheath is folded upon itself, forming a plurality of layers of material in a radial direction from the longitudinal axis of the elongate core member. The wrapped sheath is tightly wrapped about the elongate core member such that the wrapped sheath and elongate core member travel as a unit during navigation within the blood vessel of the body of a patient. The wrapped sheath is expandable to a larger diameter in order to allow a perfusate to pass through the lumen of the sheath.
