Abstract: The present invention relates to a process to produce hollow jewelry article and hollow jewelry articles produced in accordance with the said process. The process comprises a joining least two predetermined wax portions into a wax model and casting the said wax model into a partially or fully hollow jewelry article.

Abstract: 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.
