Systems and methods for electroporation are provided. An electroporation system includes a catheter including a plurality of electrodes, and a pulse generator coupled to the catheter, the pulse generator configured to generate a waveform to be delivered using at least one of the plurality of electrodes. The waveform includes a first pulse having a first polarity, a first pulse amplitude, and a first pulse width, and a second pulse having a second polarity, a second pulse amplitude, and a second pulse width, wherein the first and second pulses are separated by an interpulse delay, and wherein at least one of i) the first pulse amplitude is different than the second pulse amplitude and ii) the first pulse width is different than the second pulse width.

One aspect of the present disclosure is a medical treatment tool including a first arm having a first end and a second end and a second arm having a first end and a second end, wherein the first end of the first arm and the first end of the second arm are coupled such that a distance between the second end of the first arm and the second end of the second arm is adjustable. Each of the first arm and the second arm comprises: a conductor extending from the first end to the second end and exposed at the second end; a support containing a composite material made of a resin and a reinforcing material as a main component and extending along the conductor; and a cover covering the conductor and the support.

The invention generally relates to systems and methods for therapeutically modulating nerves in or associated with a nasal region of a patient for the treatment of a rhinosinusitis condition.

A method of displaying an operational parameter of a surgical system is disclosed. The method includes receiving, by a cloud computing system of the surgical system, first usage data, from a first subset of surgical hubs of the surgical system; receiving, by the cloud computing system, second usage data, from a second subset of surgical hubs of the surgical system; analyzing, by the cloud computing system, the first and the second usage data to correlate the first and the second usage data with surgical outcome data; determining, by the cloud computing system, based on the correlation, a recommended medical resource usage configuration; and displaying, on respective displays on the first and the second subset of surgical hubs, indications of the recommended medical resource usage configuration.

An electrosurgical device including an elongated body extending from a proximal portion to a distal portion and defining an internal passageway configured to convey tissue from the distal portion to the proximal portion, and a coring electrode positioned at the distal portion of the elongated body, where the coring electrode is at an opening to the internal passageway, and where the coring electrode is configured to deliver electromagnetic energy to adjacent tissue to cut a volume of the tissue as the tissue is conveyed into the internal passageway.

An electrosurgical device including an elongated body extending from a proximal portion to a distal portion and defining an internal passageway configured to convey tissue from the distal portion to the proximal portion; a coring electrode at the distal portion of the elongated body, where the coring electrode is positioned at an opening to the internal passageway, and where the coring electrode is configured to deliver electromagnetic energy to adjacent tissue to cut a volume of the tissue as the tissue is conveyed into the internal passageway; and a powered conveyance mechanism positioned within the internal passageway configured to further cut the volume of the tissue and convey the volume of the tissue proximally within the internal passageway.

An electrosurgical instrument can be provided that includes a pair of opposing jaws, a channel in at least one of the opposing jaws for receiving a reciprocating blade, and a fluid distribution system in communication with the one or more fluid openings located within the channel for delivering a fluid to the jaws.

A tool assembly for use with an electrosurgical device for cutting tissue includes a base portion, a return lead, an electrical insulator, a center pin, and an active lead. The center pin extends from the base portion and through a lumen of the electrical insulator. The active lead is securely fixed to the base portion and extends between the base portion and a distal portion of the center pin such that a portion of the active lead extends around the distal portion of the center pin and first and second segments of the active lead are spaced apart from the return lead. Upon activation, electrosurgical energy is transmitted from the active lead through tissue to the return lead to cut tissue in contact with the active lead.

The invention generally relates to systems and methods for therapeutically modulating nerves in or associated with a nasal region of a patient for the treatment of a rhinosinusitis condition.

Various systems and methods for controlling the activation of energy surgical instruments are disclosed. An advance energy surgical instrument, such an electrosurgical instrument or an ultrasonic surgical instrument, can include one or more sensor assemblies for detecting the state or position of the end effector, arm, or other components of the surgical instrument. A control circuit can be configured to control the activation of the surgical instrument according to the state or position of the components of the surgical instrument.
