1. A device for treating bone, comprising:
- an elongated shaft adapted for insertion through a cortical bone portion of a bone and into a cancellous bone portion of the bone, the elongated shaft having a linear shape extending along a longitudinal axis, at least a portion of the shaft being movable into a curved configuration within cancellous bone; and
a cutting element attached to said movable portion of the shaft, the cutting element moveable between a first configuration co-linear with the shaft and a second configuration away from the shaft with the movable portion of the shaft in the curved configuration to cut a plane in cancellous bone.

Abstract
Apparatuses, methods, and kits for treating bone (e.g., vertebral compression fractures) includes a shaft with a working end that can be bent into an arc-shaped working end. The shaft can be introduced into a bone (e.g., introduced through a sleeve into cancellous bone) and carries a cutting element that can be actuated across the arc-shaped working end to cut a plane in cancellous bone, which can optionally be filled with a bone fill material (e.g., bone cement).

10. A method of treating bone, comprising:
-
creating a path into a cancellous bone portion in a bone;
inserting an elongated shaft along a longitudinal axis through said path into cancellous bone, the shaft having a cutting element attached to a working end of the shaft;
moving the working end of the shaft into a curved configuration; and
cutting a plane in cancellous bone with the cutting element. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23)

24. A kit for treating a bone, comprising:
-
an injector configured for introduction into a bone, the injector configured to deliver a bone cement through a channel thereof into the bone; and
a cutting tool comprising an elongated shaft adapted for insertion through a cortical bone portion of the bone and into a cancellous bone portion of the bone, and a cutting element attached to said portion of the shaft, the cutting element moveable between a first configuration co-linear with the shaft and a second configuration not co-linear with the shaft to cut a plane in cancellous bone - View Dependent Claims (25)
