Abstract
A device for use with a debridement system is disclosed. The device includes an outer tubular shaft having an inner surface defining a lumen along an axis, the inner surface having an inner surface diameter. An inner tubular shaft is disposed within the lumen and rotatable within the outer tubular shaft. The inner tubular shaft includes an outer surface having an outer surface diameter less than the inner surface diameter. The inner surface of the outer tubular shaft with the outer surface of the inner tubular shaft forms a channel along the axis to receive fluid from the fluid source. The rotor is disposed in the channel and includes an axially extending helicoid blade coupled to the inner tubular shaft. The blade rotates within and with respect to the outer tubular shaft and exerts an axial thrust on the fluid in the channel with respect to the outer tubular shaft.
