US Patent 10188456 Electrode assembly for RF energy enabled tissue debridement device

A bipolar electrosurgical device is disclosed that operates in a mechanical cutting mode and a hemostasis mode. The device includes a housing and a blade assembly extending from the housing. The blade assembly forms a cutting tip and cutting window at a distal end region to provide mechanical cutting of tissue and first and second electrode assemblies to provide electrical energy to tissue. The first electrode assembly includes an outer shaft defining a first electrode surface and the second electrode assembly includes an electrode body extending along and electrically isolated from an outer shaft and defining a U-shape in cross section.
