Publication number: 20090088737Abstract: A medical device system and method provide an RF electrosurgical generator coupled to an electrosurgical electrode via a patient box disposed in close proximity to the patient. An RF signal is delivered from the generator to the patient box where signal power is increased and the RF signal delivered to the electrosurgical electrode. The patient box is coupled to the electrosurgical electrode by a short cable capable of carrying an HV, high frequency 5 MHz signal without leakage. An electrical characteristic associated with the electrosurgical electrode is monitored and a desired RF power output and duty cycle maintained by adjusting DC input voltage applied to an RF amplifier, responsive to the monitoring. The system determines when the electrosurgical cutting electrode has started cutting and switches from a start mode to a run mode having a different RF duty cycle and a reduced RF power output controlled by a servo system.Type: ApplicationFiled: August 27, 2008Publication date: April 2, 2009Inventors: Derek Daw, James Huntington Dabney

Patent number: 7175618Abstract: A high frequency electrosurgical power generator configured to produce electrical power at a frequency of about 1 to about 14 MHz and preferably having an essentially sinusoidal waveform with a voltage level up to 1,000 Vrms, and a current level up to 5 Amps. The output of the high frequency electrosurgical power generator is connected to an electrosurgical tool configured to receive the voltage and current produced by the electrosurgical power generator and deliver the voltage and current to an electrosurgical site. The output of the electrosurgical generator preferably is an essentially sinusoid waveform with a frequency between about 3 MHz and about 8 MHz, up to about 700 volts rms, up to about 2 amps, with a total power of up to 1,000 watts.Type: GrantFiled: September 9, 2003Date of Patent: February 13, 2007Assignee: SenoRx, Inc.Inventors: James Huntington Dabney, Richard L. Quick, Conrad Sawicz, Paul Lubock, Dan Kussman

Patent number: 7029628Abstract: The invention discloses a system, method and medical device for measuring various hemoglobin derivatives, such as oxyhemoglobin, reduced hemoglobin, partial hemoglobin, carboxyhemoglobin, methemoglobin and sulfhemoglobin in whole or in hemolyzed blood. The novel method uses a statistical approach to enable the design of a portable co-oximeter. This portable co-oximeter utilizes compact light sources, such as light emitting diodes or light emitting lasers, to emit light in the visible region. Being portable, the device is a point-of-care device that can be used in emergency situations by paramedics, in the emergency room, and in a physicians office to detect and measure the concentrations and/or percentages of functional and non-functional hemoglobin derivatives in a patient's blood.Type: GrantFiled: December 28, 2000Date of Patent: April 18, 2006Assignee: Stat-Chem Inc.Inventors: Lisa A. Tam, James Huntington Dabney, Michael H. Burnam, Martin J. Patko

Publication number: 20020198526Abstract: A subcutaneously formed in place orthopedic fixation device is provided, such as for fixation of the spine or other bone or bones. The device comprises an inflatable member, such as a tubular balloon. A heat source is provided in thermal communication with the interior of the balloon. The balloon is positioned at a treatment site while in a flexible, low crossing profile configuration. The balloon is thereafter inflated with a hardenable media, and heated to accelerate hardening of the media. Methods and delivery structures are also disclosed.Type: ApplicationFiled: May 31, 2002Publication date: December 26, 2002Inventors: Samuel M. Shaolian, George P. Teitelbaum, To V.

Patent number: 6057374Abstract: An electrotransport drug-containing composition is provided. The composition includes a drug to be delivered through a body surface (eg, skin) of a patient, and a permeation enhancer which is solid or semisolid at temperatures typically encountered during storage of pharmaceuticals (eg, temperatures up to at least about 25.degree.
