Abstract
A tissue removal device may comprise a handle portion and a tissue removal mechanism coupled to the handle portion. The tissue removal mechanism may include a tubular member having a lumen therethrough and an elongate member rotatably and slidably disposed within the lumen of the tubular member. A proximal end of the elongate member may be coupled to a drive source to impart rotational movement thereof. A distal end of the elongate member may include an impeller for cutting tissue. The elongate member may be configured to exit the distal end of the lumen of the first tubular member, such that the distal end of the second tubular member is distal to the distal end of the first tubular member. The impeller may include a blunt distal end to minimize undesirable tissue damage when the distal end of the elongate member is distal to the distal end of the tubular member.
