Abstract
The present invention provides a system for treating a blood vessel. The blood vessel treatment system includes a hollow guidewire having a central lumen, an occlusion balloon attached proximate to a distal end of the hollow guidewire, and an inflation catheter slidable over the hollow guidewire. An annular inflation lumen formed between the inflation catheter and the hollow guidewire fluidly communicates with the central lumen of the hollow guidewire, allowing inflation fluid to flow through the annular inflation lumen and into a distal portion of the central lumen to inflate the occlusion balloon.
