Document Type and Number:
Japanese Patent JP2003521961
Kind Code:
A
Abstract:
Apparatus and methods for perfusing ischemic myocardium are provided using a tubular member having an end region adapted to be disposed in a portion of a patient's venous vasculature. The end region includes a lumen and a valve in communication with the lumen 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. An occlusion element optionally may be provided in the end region that retains the tubular member within the patient's venous vasculature and occludes the flow of blow around the lumen.
