Woven structures and associated systems for weaving such structures are disclosed. Some disclosed innovations pertain to braided structures, such as braided wire structures, with axially asymmetric woven structures (or 'directional meshes') being examples. Other innovations disclosed herein pertain to methods of manufacturing woven structures, with automated methods of braiding directional meshes being examples. Some directional mesh embodiments can be configured and used as energizable electrodes for electrosurgical therapies, for example, bipolar vaporization therapies.

Method for forming a directional mesh

An electrosurgical assembly is disclosed, the assembly having two, three or more electrodes configured to provide advantageous tissue removal and precision for conducting electrosurgical procedures, including improved ablation and coagulation of tissue. The electrodes are configured and arranged so that energy can be applied in a highly uniform and precise fashion, depending upon the application. In addition, the electrosurgical assembly allows flexibility in use by, in some embodiments, allowing selective switching of the active and return electrodes, and also selective switching between ablation and coagulation modes. In certain embodiments the invention includes one or more electrodes having the ability to undergo changes in shape.

Electrosurgical device

Directional mesh and associated systems

An improved method and equipment for tissue/vessel sealing is disclosed for the sealing, coagulation and transection of tissue during surgical procedures. The improvement is accomplished through better management of heat and moisture present during tissue treatment by having tissue grasping surfaces comprised of an outer non-conducting region and an inner conductive region, and including channels in the jaw assembly to direct steam and moisture away from surrounding tissue. The outer region follows the perimeter each jaw, isolating the treatment zone and preventing steam and excess heat from leaving the tissue treatment zone, reducing thermal margins and unintended patient burns. The outer region also prevents surrounding moisture from affecting the treatment zone and allowing more consistent results.
