ABSTRACT:
A cutter penetrates at its forward end into, and excises, obstructive tissue in a lumen in a living being by providing two spaced external segments of a conical generally hollow portion with cutting surfaces at their edges. The cutter may have a forward portion of restricted dimensions to facilitate the penetration of the cutter into the obstructive tissue. A progressively expanding portion such as a truncated cone extends rearwardly from the portion of restricted dimensions. In this way, the cutter expands the area of excision of the obstructive tissue from the lumen wall at progressive positions rearwardly from the forward end. The obstructive tissue in the lumen at the progressively expanding positions may be excised at the positions of penetration of the obstructive tissue by rotating the cutter manually or by a motor. The cutter may then be moved forwardly to penetrate the obstructive tissue through an additional distance in the lumen. The cutter may also have a hollow portion of substantially constant dimensions, such as a hollow cylinder, at the laterally expanded end. This hollow cylinder is coupled to a torque tube which has strong and resilient properties to follow the contour of the lumen and to communicate a penetrating force to the forward end of the cutter and a torque to the cutter to rotate the cutter. A vacuum may be applied to the cutter through the torque tube to remove fragments of obstructive tissue excised from the lumen.
