An electrosurgical generator is disclosed that provides radio-frequency electrical waveforms for performing surgical operations on a tissue mass. The various aspects of the present invention are embodied in an electrosurgical generator that includes a DC regulator, an amplifier, an energy recovery circuit, and a method of controlling these components to generate a desired electrical waveform for an electrosurgical operation.

Electrosurgical generator

A remotely programmable infusion system for administering liquid to a patient includes an infusion pump unit having a pump for infusing liquids operated by means of a control including a programmed processing unit and a memory chip. The processing unit operates in accordance with delivery program data stored in the memory circuit for executing an infusion delivery sequence. An output circuit is operatively disposed between the processing unit and the pump unit to control operation of the pump unit in accordance with the infusion delivery sequence. A wireless data communication circuit is operatively connected to the control for transmitting and receiving data. A programmer remote from the pump unit includes a programmed processing unit, a memory circuit, a user interface operatively associated with the processing unit for entering program commands and configuring delivery program data for storage in the memory circuit and a modem circuit operatively connected to the processing unit for transmitting and receiving data to and from the infusion pump unit. A remote communication interface unit includes a pump interface operatively communicating, in use, with the pump wireless data communication circuit, a programmer interface, including a modem circuit operatively communicating, in use, via a telephone line with the programmer modem circuit and a control circuit operatively connected to the pump interface and the programmer interface for channeling data between the pump interface and the modem circuit.

Ambulatory infusion pump

An improved directed energy surgical method and assembly is disclosed. The method and assembly contemplate the application of a directed energy stream to tissue and the application of a liquid mist stream to the tissue to reduce or eliminate smoke at the surgical site. The invention may be advantageously implemented in an assembly having a surgical pencil for emitting the directed energy stream and liquid mist stream. The liquid mist stream is generated by the surgical pencil, preferably by atomizing a liquid stream supplied thereto (e.g., pressurized via jet atomization). The invention may be utilized in connection with conventional electrosurgical, laser surgery, ultrasound, and other techniques and devices.

Directed energy surgical method and assembly

A personnel monitoring and locating system is disclosed that is particularly well suited for monitoring and/or locating underground miners. A plurality of remote terminals having transceivers associated therewith are positioned in a mine and periodically are caused to transmit interrogation signals. Each miner to be monitored is equipped with a transponder that replies to the interrogation signal with the reply signal being timewise delayed by a predetermined amount of time that is different for each of the transponders in use so that the reply from each transponder is timewise spaced from every other interrogated transponder. A host computer at the surface is linked to each remote terminal for transmission of information with information from the remote terminal being indicative of the location of each transponder equipped miner. The transponder carried by each miner is powered by the battery normally carried by the miner for powering a lamp, and the cord extending between the battery and the lamp is utilized by the transponder as a transmitting and receiving antenna.
