Claim Text:
1. A single-phase surgical blower for clearing unwanted debris from a surgical site during the anastomosis on coronary arteries while the heart continues to beat without generating additional debris and without desiccating tissue at the surgical site comprising: a source of a single-phase wash gas; a regulator for controlling a flow of the single-phase wash gas; a filter for removing unwanted particles from the wash gas; a nozzle for delivery of the single-phase wash gas to the surgical site, said nozzle diverting the single-phase was gas outward to maintain an isothermal flow of wash gas to the surgical site; and a wash gas conditioning housing located in fluid communication with the source of the wash gas, said wash gas conditioning housing including a heater for elevating a temperature of the wash gas to a tissue friendly level, a hydrophilic media and a stagnant source of vaporizable liquid located in a hydrophilic media where the vaporizable liquid and the wash gas linger as the vaporizable liquid evaporates and hydrates the wash gas while inhibiting or preventing entrainment of the vaporizable liquid into the wash gas to bring the wash gas to a conditioned gaseous single-phase state whereby directing a stream of the conditioned single phase wash gas at the surgical site blows away unwanted debris from the surgical site without liquid droplets desiccating tissue at the surgical site.
