Abstract: Methods and devices are provided for use in medical applications involving tissue removal. One exemplary powered scissors device includes a distal housing having a fixed cutting arm located thereon, an elongate member coupled to the distal housing and configured to introduce the distal housing to a target tissue site of the subject, a rotatable blade rotatably mounted to the distal housing, the rotatable blade having at least one cutting element configured to cooperate with the fixed arm to shear tissue therebetween, a crown gear located at a distal end of an inner drive tube, and a first spur gear configured to inter-engage with the crown gear and coupled with the rotatable blade to allow the crown gear to drive the rotatable blade.
