Patent Images
1. A steerable vertebroplasty device, comprising:
- an elongate, tubular body, having a proximal end, a distal end, and a central lumen extending therethrough;
a deflectable zone on the distal end of the tubular body, deflectable through an angular range;
a handle on the proximal end of the tubular body; and
a deflection control on the handle;
wherein the handle and deflection control are configured for single hand operation.
