摘要：
Disclosed herein is a steerable, curvable catheter with one, two, or more ablation elements that can be used for various applications including vertebroplasty. The catheter can include 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 an energy delivery control on the handle and one or more energy delivery elements on the distal end of the device for ablating tissue within bone. The energy delivery elements could be RF heating electrodes in a monopole or dipole arrangement although other energy delivery modalities are also contemplated. For example, the energy delivery elements include cryoprobes. Systems and methods involving the ablation catheter are also disclosed.
