Patent number: 9820794Abstract: Various devices, systems, and methods are capable of killing tumor cells by delivering cell-disrupting agents into a tumor in an inward direction from a peripheral border about the tumor. In some examples, a covering that includes one or more emissive elements encompasses at least a portion of a tumor such that the emissive element is directed inwardly toward the tumor so as to be able to introduce a cell-disrupting agent into the tumor. In further examples, the covering is incorporated into a glove.Type: GrantFiled: November 21, 2011Date of Patent: November 21, 2017Assignee: Intermountain Invention Management, LLCInventors: Mark John Ott, Troy J.

Patent number: 9820796Abstract: Methods and apparatus for the treatment of a body cavity or lumen are described where a heated fluid and/or gas may be introduced through a catheter and into treatment area within the body contained between one or more inflatable/expandable members. The catheter may also have optional pressure and temperature sensing elements which may allow for control of the pressure and temperature within the treatment zone and also prevent the pressure from exceeding a pressure of the inflatable/expandable members to thereby contain the treatment area between these inflatable/expandable members. Optionally, a chilled, room temperature, or warmed fluid such as water may then be used to rapidly terminate the treatment session.Type: GrantFiled: September 6, 2013Date of Patent: November 21, 2017Assignee: Channel Medsystems, Inc.Inventors: Daniel R. Burnett, Ric Cote, William W. Malecki, Brian M. Neil, David Beaulieu, Benjamin D. Voiles

Patent number: 9820798Abstract: Targeted ablation of parathyroidal tissue is provided through hyperthermia adjuvant therapy. An in situ localization of parathyroidal tissue is obtained. A temperature-sensitive adjuvant is instilled into the parathyroidal tissue. Hyperthermia is therapeutically induced within the parathyroidal tissue. Heat-inducing energy is targeted into the parathyroidal tissue, which selectively includes the temperature-sensitive adjuvant. Application of the heat-inducing energy to the parathyroidal tissue is continued over a therapeutic range. In a further embodiment, the targeted ablation of the parathyroidal tissue is provided through hypothermia adjuvant therapy with the targeted use of cold-inducing energy.Type: GrantFiled: March 5, 2015Date of Patent: November 21, 2017Inventor: Alan N. Schwartz

Patent number: 9820801Abstract: A method for removing hair by thermolysis is provided. The method steps include oscillating a direct current to create an alternating current (“AC”) micro-pulse, pulsing the AC micro-pulse on and off continuously, delivering the AC micro-pulse to a probe, applying the probe to a hair follicle, and inverting the direction of the AC micro-pulse on the hair follicle. When the probe is applied to the hair follicle, the AC micro-pulse travels from the top of the dermis of the hair follicle to a dermal papilla of the hair follicle. The AC micro-pulse reverses direction at the dermal papilla and travels to the top of the dermis of the hair follicle. The AC micro-pulse produces heat that destroys the tissues controlling the growth of the hair follicle.Type: GrantFiled: June 2, 2015Date of Patent: November 21, 2017Inventor: Suzanne Anderer

Patent number: 9820802Abstract: A method and system for increasing safety of cardiac ablation procedures comprises a computer based system that monitors the esophageal temperature, and a fluoroscopy (medical images) based cardiac mapping system for cryoballoon or radiofrequency (RF) ablations. The esophageal temperature is monitored utilizing an esophageal probe which may have any number of temperature sensing members. The esophageal probe may also have pre-formed shape. During atrial fibrillation ablations, based on a pre-determined increase in esophageal temperature (from any thermistor), the computer based system activates different levels of alarm(s), and/or initiates ablation energy interrupt based on pre-defined programmed values. The method and system is also used for guiding placement of cryoballoon and performing cryoablations. The placement of cryoballoon catheter or a circular catheter is based on superimposing a high resolution (dye injected) image and a live fluoroscopy image and adjusting transparency between the two images.Type: GrantFiled: July 13, 2016Date of Patent: November 21, 2017Assignee: American Medical Technologies, LLCInventors: Birinder R.
