<p>Apparatus, and methods for perfusing ischemic myocardium are provided using a tubular member (12) having an end region (16) adapted to be disposed in a portion of a patient's venous vasculature. The end region (16) includes a lumen (20), and a valve (24) in communication with the lumen (20) that controls pressure within an occluded portion of the vasculature by venting excess blood at a location proximal of a point of occlusion of the vasculature via the valve (24). An occlusion element (26) optionally may be provided in the end region (16) that retains the tubular member (12) within the patient's venous vasculature, and occludes the flow of blood around the lumen (20).</p> |
