Abstract: A needle electrode deployment shaft includes a central member and a plurality of needle electrodes. The central member has a plurality of needle advancement channels formed therein. The needle electrodes are disposed within the advancement channels and each advancement channel terminates in a ramp portion which deflects the needles radially outwardly as they are axially advanced. The ramps may be spirally or acutely configured in order to increase the distance through which the needles may be bent as they are axially advanced. Additionally, the central member may have a radially reduced distal tip in order to decrease tissue insertion forces.

Abstract: An electrode is provided. The electrode includes a contact pad composed of boron-doped polycrystalline diamond (BDD); a fiber core composed of BDD extending longitudinally from the contact pad from a first end that is in direct contact with the contact pad to an opposing second end; and a polycrystalline diamond (PCD) cladding that coats and hermetically seals the contact pad and the fiber core. A first portion of the contact pad and a second portion at or near the second end of the fiber core are not coated and hermetically scaled by the PCD cladding. A method of fabricating the electrode is also provided.

Abstract: Disclosed is a method of detecting a short circuit in the jaws of an end effector of a surgical instrument. The method includes applying a sub-therapeutic electrical signal to an electrode located in the jaws of the end effector. The sub-therapeutic electrical signal comprises a sequence of exploratory waveforms comprising pulsed current and voltage waveforms. The method includes detecting a shorted electrode when a measured electrical parameter in the jaws of the end effector is less than a predetermined value and modifying electrical current applied to the shorted electrode by the RF generator.

Abstract: Apparatus and associated methods relate to controlling electrical power of an electrotherapeutic signal that is provided to a biological tissue engaged by an electrosurgical instrument during a medical procedure. Electrical power—a product of a voltage difference across and an electrical current conducted by the engaged biological tissue—is controlled according to a therapeutic schedule. The electrotherapeutic schedule can be reduced or terminated in response to a termination criterion being met. In some examples, the termination criterion is a current characteristic, such as, for example, a decrease in current conducted by the engaged biological tissue. In some examples, the termination criterion is a biological tissue resistance characteristic, such as, for example, an increase in the biological tissue resistance that exceeds a predetermined delta resistance value.

Abstract: An electrosurgical system includes an electrosurgical instrument having an electrode with a polymeric dielectric coating; and an electrosurgical generator, which includes a power converter configured to generate RF energy; a sensor coupled to the power converter and configured to sense a parameter of the RF energy; and a controller coupled to the sensor and the power converter. The controller is configured to control the power converter to output an RF waveform to achieve conductor breakthrough through the polymeric dielectric coating. The controller is further configured to determine whether the conductor breakthrough occurred based on the parameter; and execute a treatment algorithm based on a determination of the conductor breakthrough.

Abstract: Methods and devices for both imaging and treating uterine fibroid tumors in one real-time system are provided. One minimally invasive method comprises introducing a sheath into a uterus and determining a location of a fibroid using a visualization element within or on the sheath. Upon identification, a portion of the sheath is steered to position at least one treatment needle at the determined location. The needle is then anchored in uterine tissue and the fibroid treated with the needle.
