Patent number: 8048068Abstract: A monopolar electrosurgical return electrode to prevent unwanted thermal effects in monopolar electrosurgery, accomplished in one aspect by volumetric incorporation of temperature-resistive material of positive nature into a flexible and adhesive return electrode pad is provided. The incorporation of positive temperature coefficient resistance with low resistance at room temperature will increase the local electrical resistance of the pad with an increase of the local return electrode temperature corresponding to a switching of the resistance from low to high value which in turn will lead to a reduction of the local current density. The switching temperature of the positive temperature coefficient return electrode is low enough to prevent significant thermal heating of the patient's tissue.Type: GrantFiled: March 17, 2011Date of Patent: November 1, 2011Assignee: Applied Medical Resources CorporationInventors: Zoran Falkenstein, John R. Brustad

Publication number: 20110028890Abstract: An insufflation gas warmer and humidifier apparatus and methods are provided. Insufflation gas is received from a bulky insufflation tubing. Insufflation gas received travels through, in one aspect, a channel or winding flow path, in a passage. The configuration of the passage ensures that the insufflation gas, which travels through the passage, receives sufficient heat and moisture. A humidifying reservoir humidifies the insufflation gas as the insufflation gas is passed to the passage. In one aspect, an oxygenator introduces slight amounts of oxygen into the insufflation gas. A warmer connected to the passage warms the gas in the passage. The warmer, in one aspect, contains a reactive agent that when exposed to air produces heat that is transferred to the passage to warm the insufflation gas within the passage.Type: ApplicationFiled: October 12, 2010Publication date: February 3, 2011Applicant: Applied Medical Resources CorporationInventors: Charles C.

Publication number: 20090248013Abstract: Phase end point determination is provided to automatically halt the application of energy to tissue. Prior to the application of energy, the phase end point determination is identified by measuring the product of permittivity and conductivity of the tissue to be treated. An electrosurgical system can include an electrosurgical generator, a feedback circuit or controller, and an electrosurgical tool. The feedback circuit can provide an electrosurgery endpoint by determining the phase end point of a tissue to be treated. The electrosurgical system can include more than one electrosurgical tool for different electrosurgical operations and can include a variety of user interface features and audio/visual performance indicators. The electrosurgical system can also power conventional bipolar electrosurgical tools and direct current surgical appliances.Type: ApplicationFiled: April 1, 2009Publication date: October 1, 2009Applicant: Applied Medical Resources CorporationInventors: Zoran Falkenstein, Christopher J.

Publication number: 20080255597Abstract: The invention relates to a tissue morcellator for minimally invasive surgery. The morcellator has a metallic cutting ring mounted on a visually transparent hollow cylinder, which in combination with a visually transparent outer morcellator tube enables a surgeon to visualize the inside of the morcellator shaft for detection of loose tissue fragments in the device. A tenaculum used with the morcellation device has a spacer for preventing contact with the blade. The cutting tube can oscillate, rather than rotate, along the longitudinal axis of the cutting tube. The morcellator utilizes an extendable tissue guide on the outer tube of the morcellator shaft for preventing the tissue from rotating along the longitudinal axis of the morcellator tube. This allows the tissue to be continuously rotated into the morcellator device for continuous peel. The tissue guide can also be fully retracted to allow for coring of the bulk tissue.Type: ApplicationFiled: April 14, 2008Publication date: October 16, 2008Applicant: APPLIED MEDICAL RESOURCES CORPORATIONInventors: Boun Pravong, Kennii Pravongviengkham, Matthew M.

Publication number: 20080058792Abstract: A monopolar electrosurgical return electrode to prevent unwanted thermal effects in monopolar electrosurgery, accomplished in one aspect by volumetric incorporation of temperature-resistive material of positive nature into a flexible and adhesive return electrode pad is provided. The incorporation of positive temperature coefficient resistance with low resistance at room temperature will increase the local electrical resistance of the pad with an increase of the local return electrode temperature corresponding to a switching of the resistance from low to high value which in turn will lead to a reduction of the local current density. The switching temperature of the positive temperature coefficient return electrode is low enough to prevent significant thermal heating of the patient's tissue.Type: ApplicationFiled: September 1, 2006Publication date: March 6, 2008Applicant: APPLIED MEDICAL RESOURCES CORPORATIONInventors: Zoran Falkenstein, John R.

Patent number: 6971939Abstract: A non-oxidizing electrode arrangement for an excimer lamp that is formed by coating an electrode of the lamp with a layer of protective layer that prevents the electrode from oxidizing. The protective layer is preferably transparent and possesses a low permeability for oxygen (e.g., silicon oxide, magnesium fluoride, calcium fluoride). The interior of the excimer lamp is evacuated to a pressure level that is lower than the pressure level surrounding the excimer lamp at any time during the non-oxidizing electrode formation process in order to assist in preventing the excimer lamp from fracturing.Type: GrantFiled: May 28, 2004Date of Patent: December 6, 2005Assignee: Ushio America, Inc.Inventors: Holger Claus, Zoran Falkenstein
