摘要： Systems and methods to confirm safe delivery of treatment energy to a patient by identifying a presence of a fault in an energy delivery pathway and identifying a location of the fault within the device. The system includes a processing unit configured to calculate blood impedances external to the device based on known impedance characteristics of the device, and then to calculate impedances within the device during energy delivery based on the calculated blood impedances. The processing unit prevents the delivery of energy in an energy delivery pathway that is determined to be compromised. The processing unit is also configured to compare times for two different frequencies to travel a predetermined distance, the difference in the times corresponding to a location of a fault within the energy delivery pathway.

摘要： System and methods for channeling a path into bone include a trocar having a proximal end, distal end and a central channel disposed along a central axis of the trocar. The trocar includes a distal opening at or near the distal end of the trocar. The system includes a curved cannula sized to be received in the central channel, and having a curved distal end configured to be extended laterally outward from the distal opening in a curved path extending away from the trocar. The curved cannula has a central passageway having a diameter configured to allow a probe to be delivered through the central passageway to a location beyond the curved path.

摘要： A device is described for treating a nasal airway by modifying a property of a nasal tissue of or near a nasal valve of the airway, without using a surgical incision or an implant, to decrease airflow resistance or perceived airflow resistance in the nasal airway. Various embodiments include an elongate shaft, a bipolar radiofrequency delivery member extending from one end of the shaft, and a handle attached to the elongate shaft at an opposite end from the radiofrequency delivery member. The radiofrequency delivery member is sized to be inserted into a nose and configured to at least temporarily deform the nasal tissue and deliver radiofrequency energy. The radiofrequency delivery member includes two rows of protruding electrodes disposed on a tissue contact surface, and the device is configured to deliver radiofrequency energy from one row of electrodes to the other row of electrodes.

摘要： A system and method for the safe delivery of treatment energy to a patient, which includes verification of system integrity before, during, or after the delivery of treatment energy and provides several mechanisms for rapid termination of the delivery of potentially harmful energy to the patient when a fault condition in the device and/or system is identified. The system may include an energy generator having processing circuitry to determine if there is a fault condition in the system and to automatically terminate a delivery of treatment energy when the processing circuitry determines there is a fault condition. The method may generally include performing a series of pre-checks, synchronizing a treatment energy delivery to the proper segment of the heart's depolarization pattern, configuring the system for treatment energy delivery, delivering the treatment energy, and performing post-treatment evaluation.

摘要： Aspects of the present disclosure are presented for a single surgical instrument configured to grasp, seal, and/or cut tissue through application of therapeutic energy, and also detect nerves through application of non-therapeutic electrical energy. A medical device may include two jaws at an end effector, used to apply therapeutic energy and to perform surgical procedures. The therapeutic energy may be in the form of ultrasonic vibrations or higher voltage electrosurgical energy. One of the jaws may be configured to cut tissue through application of the blade. In addition, one or both of the two jaws may be configured to apply nontherapeutic energy for nerve stimulation probing. The application of therapeutic energy may be disabled while the nontherapeutic nerve stimulation energy is applied, and vice versa. The nontherapeutic nerve stimulation energy may be applied to the use of one or more probes positioned near one or both of the jaws.

摘要： An electrode structure for a distal tip of an electrosurgical instrument that enables efficient delivery of radiofrequency (RF) energy in a forward (distal) direction and uniform delivery of microwave energy for ablation in a region surrounding the distal tip. The instrument comprises a tip body having a first electrode and a second electrode, where the second electrode is spaced from the first electrode exposed dielectric material. The first electrode is connected through the tip body to an inner conductor of a coaxial feed. The second electrode is electrically connected to the outer conductor of the coaxial feed by a field-shaping conductive structure formed in or on the tip body. The field-shaping conductive structure is configured to shape a radiation profile of microwave energy emitted from the tip body.

摘要： An ultrapolar electrosurgery blade includes top and bottom thin elongated conductive members in vertical alignment and spaced apart from one another along their lengths, a non-conductive housing or coating covering both the top and bottom thin elongated conductive members and the space located between them to create opposing non-conductive sides of the blade with a non-conductive cutting end located between exposed conductive cutting ends, and both return and active contact layers located on each of the opposing non-conductive sides of the blade. An ultrapolar electrosurgery blade assembly having argon beam capability further includes a non-conductive tube member having a slot positioned over the top of the ultrapolar electrosurgery blade and a conductive hollow tubular member contained within at least a portion of the non-conductive tube member.
