Latest Patents

Vacha's latest inventions include two notable patents that focus on electrosurgical instruments:

1. **Electrosurgical Generator and Methods**: This technology is directed to a radio frequency (RF) power generator and a feedback control system designed to regulate the electrical power delivered to a cutting filament within an electrosurgical instrument. The instrument utilizes this energy to create a cutting arc for ablating tissue masses, facilitating access to target tissue. As the instrument forms a basket-like receptacle around the target tissue, the RF power generator adjusts the power delivered based on measurements derived from a differential phase angle between current and voltage outputs. This ensures a uniform power density along the exposed length of the filament during the surgical process.

2. **Electrosurgical Method and Apparatus with Varying Stiffness Capture Components**: This invention describes an apparatus and method for cutting and resecting tissue volumes. It includes electrosurgical filaments and deployable capture components that extend to form a spheroidal receptacle around the tissue for resection. The apparatus creates an elliptical path through a sequence of extensions and contractions, integrating components of varying stiffness to optimize the surgical process.
