Devices and methods using an expandable body with internal restraint for compressing cancellous bone
First Claim
Patent Images
1. A method comprising the steps ofproviding a structure capable of compressing cancellous bone and comprising extruding an expandable body and coextruding an internal membrane within the body that directs expansion of the body,inserting the expandable body inside bone,causing directed expansion of the body in cancellous bone, andcompacting cancellous bone by the directed expansion.

Abstract
Devices and methods compress cancellous bone. In one arrangement, the devices and methods make use of an expandable body that includes an internal restraint coupled to the body. The internal restraint directs expansion of the body. In one arrangement, a method for treating bone inserts the device having the internal restraint inside bone and causes directed expansion of the body in cancellous bone. Cancellous bone is compacted by the directed expansion.

18. A method comprising the steps of
providing a structure capable of compressing cancellous bone comprising extruding an expandable body and coextruding an internal membrane within the body that directs expansion of the body, the body including material that, during the expansion in cancellous bone, applies a force capable of moving fractured cortical bone, inserting the expandable body inside bone, causing constrained expansion of the body in cancellous bone, and compacting cancellous bone by the constrained expansion.

23. A method comprising the steps of
inserting a device inside bone, the device comprising a body adapted to be inserted into bone and undergo expansion in cancellous bone to compact cancellous bone, the body including material that, during the expansion in cancellous bone, applies a force capable of moving fractured cortical bone, and further includes an interior membrane to constrain the expansion in cancellous bone, causing constrained expansion of the body in cancellous bone, and compacting cancellous bone by the constrained expansion.

35. A method comprising the steps of
inserting an expandable body inside bone, the expandable body including an internal restraint coupled to the body which directs expansion of the body, and causing directed expansion of the body in cancellous bone to move vertebral end plates.
-
36. A method comprising the steps of
inserting an expandable body inside bone, the expandable body including an internal restraint coupled to the body which directs expansion of the body, and causing directed expansion of the body in cancellous bone to lift tibial plateau depressions.
-
37. A method comprising the steps of
inserting an expandable body inside bone, the expandable body including an internal restraint coupled to the body which directs expansion of the body, and causing directed expansion of the body in cancellous bone to lift proximal humerus depressions.
-
38. A method comprising the steps of
inserting an expandable body inside bone, the expandable body including an internal restraint coupled to the body which directs expansion of the body, and causing directed expansion of the body in cancellous bone to move cortical bone.
-
40. A method comprising the steps of
inserting an expandable body inside bone, the expandable body including an internal restraint coupled to the body which directs expansion of the body, and causing directed expansion of the body in cancellous bone to compress cancellous bone.
