Abstract:
1. A medical device comprising: (a) a hollow elongate body having an open distal end, a proximal end, and a side port adjacent the distal end; and (b) a rotatable member having an elongate shaft with a raised helical blade having a cutting edge extending along at least a portion of the elongate shaft, the raised helical blade extending laterally outward from the elongate shaft, and with a tissue morselizer that includes a drill bit with a tissue-morselizing tip, said elongate shaft disposed in part within said hollow elongate body and extendable at least in part through the open distal end, wherein rotation of the rotatable member in a first direction causes the tip to morselize tissue or material and progressive movement of the helical blade severs tissue or material that is engaged with the side port.
