Directional Kyphoplasty Device and Method of Using Such a Device

A device for correcting a compression-type fracture comprising:

• a housing at a proximal end of the device;
• a cannula extending from the housing and through a directional balloon;
• and
• a tip at a distal end of the cannula,
• wherein the cannula comprises an outer tube for supplying fluid to the balloon and an inner tube positioned within the outer tube for supplying cement through at least one of an axial opening and a radial opening in the distal end of the cannula.

A method of correcting a compression-type fracture comprising:

• inserting a device into a fracture site, the device having a housing including a fluid portion containing a fluid and a cement portion containing a cement, a cannula extending from the housing and including a first passageway and a second passageway, and a balloon engaged with a portion of the cannula, wherein with the device in a first position, the first passageway is in communication with the fluid portion so that the fluid is flowable to the balloon, and wherein with the device in a second position, the second passageway is in communication with the cement portion so that the cement is flowable out of a portion of the cannula,
• inflating the balloon with a fluid supplied through the second passageway to elevate fragments of the fracture;
• injecting cement from the first passageway into the opening created by elevating the fragments of the fracture;
• and
• removing the device from the fracture site,
• wherein the balloon is deflated before the injection of the cement or simultaneous with the injection of the cement.

A method of correcting a compression-type fracture comprising:

• elevating bone fragments of the fracture to create a space;
• and
• filling the space with bone cement,
• wherein the space created by the elevation of the bone fragments has directionality.
