Abstract
Systems for bone and spinal stabilization, fixation and repair include intramedullar nails, intervertebral cages and prostheses, remotely activatable prostheses, tissue extraction devices, and electrocautery probes. The intramedullar nails, intervertebral cages and prostheses, are designed for expansion from a small diameter for insertion into place to a larger diameter which stabilizes, fixates or repairs the bone, and further can be inserted percutaneously. Remotely activatable prostheses can be activated from an external unit to expand and treat prosthesis loosening. Tissue extraction devices, and electrocautery probes are used to remove tissue from desired areas.
Claims27
A medical device for treatment of broken bones having an intramedullary cavity, the bone being provided with a bore formed through the exterior surface of the bone and extending into the intramedullary cavity, comprising:
- a bone fixture for insertion through the bore of the bone and into the intramedullary cavity, said bone fixture comprising a diameter-expandable, metallic balloon tube having an exterior circumferential surface, said tube having a reduced first diameter for insertion through the bore and into the intramedullary cavity and a second expanded diameter, wherein when fluid is introduced into said bone fixture it radially increases in diameter from said reduced first diameter to said second expanded diameter, at least a portion of said exterior circumferential surface coming into contact with a portion of the side wall of said intramedullary cavity.
