 new patent  Radio frequency generator and a cordless medical cauterization and cutting device

A circuit for generating a radio-frequency signal for a surgical device is disclosed. The circuit has a voltage regulator that supplies direct current (DC) voltage, a first MOSFET, a second MOSFET, and a MOSFET driver. The MOSFET driver receives the DC voltage supplied from the voltage regulator and has a... Covidien Ag

Method and system for controlling an output of a radio-frequency medical generator having an impedance based control algorithm

A system for performing an electrosurgical procedure at a surgical site is disclosed. The system includes a sensor configured to continually sense an electrical and/or a physical property of tissue at a surgical site and to generate a sensor signal as a function thereof. The system also includes a control... Covidien Ag

Electrosurgical generator and methods

The disclosed technology is directed to a RF power generator and feedback control system used to regulate the electrical power delivered to a cutting filament (i.e., a cutting electrode) of an electrosurgical instrument. The electrosurgical instrument uses the delivered energy to form a cutting arc for ablating a tissue mass... Covidien Ag

Vessel sealing instrument with electrical cutting mechanism

An end effector assembly for use with an instrument for sealing vessels and cutting vessels includes a pair of opposing first and second jaw members which are movable relative to one another from a first spaced apart position to a second position for grasping tissue therebetween. Each jaw member includes... Covidien Ag

Vessel sealing forceps

A removable electrode assembly for use in combination with a forceps having opposing end effectors and a handle for effecting movement of the end effectors relative to one another. The electrode assembly includes a housing which is removably engageable with the forceps and a pair of electrodes which are attachable... Covidien Ag

Vessel sealer and divider with non-conductive stop members

An endoscopic bipolar forceps includes an elongated shaft having opposing jaw members at a distal end thereof. The jaw members are movable relative to one another from a first position wherein the jaw members are disposed in spaced relation relative to one another to a second position wherein the jaw... Covidien Ag

Method and system for compensating for external impedance of energy carrying component when controlling electrosurgical generator

A control system for use with an electrosurgical generator which delivers electrosurgical energy to tissue has a control module. The module includes a processor executing an algorithm. The algorithm has the steps of determining a sensed voltage value corresponding to a sensed voltage signal output by the electrosurgical generator and... Covidien Ag

Vessel sealing system

An electrosurgical system is disclosed. The electrosurgical system includes an electrosurgical generator adapted to supply electrosurgical energy to tissue. The electrosurgical generator includes impedance sensing circuitry which measures impedance of tissue, a microprocessor configured to determine whether a tissue reaction has occurred as a function of a minimum impedance value...
