摘要： A device for cutting tissue including (a) an elongated shaft body defining a drive lumen, (b) a cutting head extending from a distal end of the elongated shaft body and being rotatable via a drive shaft disposed within the drive lumen, and (c) a retainer for keeping the cutting head attached to the shaft body if the cutting head becomes detached from the drive shaft or if the drive shaft breaks. A flexible drive shaft including (i) a core configured for resisting helixing, and (ii) at least one outer layer configured for transferring torque. A method of producing a flexible drive shaft including providing a core configured for resisting helixing, and wrapping the core with at least one outer layer of wires configured for maintaining high torsional rigidity. Related apparatus and methods are also described.

摘要： An elongate tool with a cutting end. In some embodiments the end is bendable. Optionally, the end is bendable between two cutting edges. Optionally or alternatively, the end includes both a forward cutting edge and a side cutting edge. The tool may be sized for hand-held use, with control from outside the body, for treating a spinal stenosis.
