摘要： This is a medical catheter made up of a body having on its distal end portion an expandable balloon and, proximal of the balloon, a delivery lumen ending in a port through which therapeutic or diagnostic agents may be delivered. In one variation, a single inflation/wire lumen extends from the catheter proximal end to the catheter distal end, through which the balloon is inflated with pressurized fluid and through which a guide wire extends. The guide wire may have a valve plug for selectively seating against a valve seat of the catheter distal end to seal the inflation/wire lumen for balloon inflations. In another variation, a vaso-occlusive agent is disposable within a delivery lumen in a catheter coupled with a steerable guidewire. The delivery lumen ends in a delivery port near to and proximal of an expandable balloon located at the catheter's end. A single inflation/wire lumen may also be provided for facilitating both balloon inflation and guide wire tracking.
