Abstract

The present invention includes a guidewire device capable of delivering perfusion fluids to a vascular site while at the same time exhibiting handling characteristics associated with existing non-perfusion guidewires. Preferred embodiments include a perfusion guidewire which closely matches the dimensions and physical characteristics of standard guidewires. Preferred embodiments also permit high pressure perfusion of supersaturated solutions, and include a liquid flow path which will not promote bubble generation or growth, or destabilize a supersaturated solution.
