Abstract: 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.

Abstract: 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.

Abstract: A surgical bone cutting device, including a handle configured to facilitate operation and control of said device by an operator, and an elongated hollow member extending from the handle, the hollow member having a proximal end and a distal end; wherein the hollow member includes an opening at the distal end thereof and a rotatable cutting element extending through the opening, and wherein the hollow member includes a first bend at the proximal end thereof, such that the part of the hollow member distal to the proximal bend is offset a central axis of the hand.

Abstract: Surgical tools for removal of tissue, namely instruments, devices and methods for surgical tissue cutting with a cylindrical cutting burr bit extending from an elongated hollow member and connected to a shaft for actuating rotation motion of said burr bit to cut/remove tissue from a target location, while mitigating the harm of damaging surrounding tissue.
