Devices, systems and methods for cutting and sealing of tissue such as bone and soft tissue. Devices, systems and methods include delivery of energy including bipolar radiofrequency energy for sealing tissue which may be concurrent with delivery of fluid to a targeted tissue site. Devices include debridement devices which may include a fluid source. Devices include inner and outer shafts coaxially maintained and having cutters for debridement of tissue. An inner shaft may include electrodes apart from the cutter to minimize trauma to tissue during sealing or hemostasis. Devices may include a single, thin liner or sheath for electrically isolating the inner and outer shafts.
