Patent number: 8765116Abstract: An apparatus and method for administering focused energy to a body using either a single energy applicator or multiple energy applicators to supply heat prior to, concurrently with and/or after delivery of a drug, gene and/or viral vector. A multi-modality treatment using a localized, focused and/or regional heating apparatus, which supplies heat to a defined area of a patient's body. The apparatus is used heat is used to pretreat a specific body site, to activate thermoactivated drugs, genes, or viral vectors, and/or to deliver drugs, genes, or viral vectors to the specific body site. The heating apparatus is provided with one or more variable and adjustable probes and one or more delivery ports heat the specific treatment site and to deliver the thermoactivated drugs and genes to the specific treatment site. Each probe may optionally be provided with one or more temperature sensors to allow for the temperature in the specific treatment site and the surrounding tissue to be properly regulated.Type: GrantFiled: November 17, 2005Date of Patent: July 1, 2014Assignee: Medifocus, Inc.Inventor: John Mon

Patent number: 8476242Abstract: A method of treating cancer by introducing heat into cancerous tissue and delivering a liposome containing an active agent or a thermo-activated drug, gene or virus to said tissue. The heat delivered is sufficient to release the active agent or activate the thermo-activated drug, gene or virus. The cancer can be esophageal cancer. The liposome containing an active agent or a thermo-activated drug, gene or virus can be a thermosensitive liposome. The active agent can be an anti-neoplastic agent, for example doxorubicin.Type: GrantFiled: September 27, 2006Date of Patent: July 2, 2013Assignee: Medifocus, Inc.Inventor: John Mon

Patent number: 8414501Abstract: A rectal thermal monitor for transrectal prostate temperature measurement includes a handle arranged in a proximal end portion of the monitor for gripping by a user, an elongate shaft extending from the handle, and an expandable distal probe portion arranged on a distal end of the shaft. The distal probe portion is arranged at a position opposite the handle portion, and is shaped to facilitate insertion through an anal sphincter and into a rectum of a patient. A cover element, is provided for covering at least a portion of the distal probe portion, and is made from a resilient material. A temperature sensing element is arranged within the distal probe portion, beneath the cover element, and is adapted and configured to sense a temperature of the prostate of the patient through the rectum wall of the patient. Further, and actuator can be provided to actuate the expandable distal probe portion, to increase a diameter thereof.Type: GrantFiled: December 23, 2008Date of Patent: April 9, 2013Assignee: Medifocus, Inc.Inventors: Brian M. Hanley, Michael S. H. Chu, Kenneth J. Daignault, Aidan Petrie, Justin Sirotin, David Robson, Andrew W. Marsella, Dan Nelsen, Michael Weiser, Ramin N. Tehrani

Patent number: 8412346Abstract: An induction heating apparatus includes a first interventional device and a second interventional device. The first interventional device includes an electrically conductive material. The first interventional device is adapted for implantation inside a body and for receiving an alternating current. The second interventional device comprises a magnetically conductive material. The second interventional device is adapted for implantation inside the body in close proximity to the first interventional device. With both devices placed inside the body, the second interventional device magnetically couples with the first interventional device and the second interventional device generates heat upon the application of the alternating current to the first interventional device thereby heating the body site.Type: GrantFiled: February 14, 2012Date of Patent: April 2, 2013Assignee: Medifocus, IncInventors: Barry N. Gellman, Jozef Slanda, Kimberly Paddock

The probe portion is arranged at a position opposite the handle portion, and is shaped to facilitate insertion through an anal sphincter and into a rectum of a patient. A temperature sensing element is arranged within the distal probe portion and is adapted and configured to sense a temperature of the prostate of the patient through the rectum wall of the patient. The probe portion can include one or more compliant materials and/or be shaped so as to compress during insertion through the anal sphincter of the patient.Type: GrantFiled: September 26, 2008Date of Patent: April 2, 2013Assignee: Medifocus, Inc.Inventors: Christopher L. Oskin, Brian M. Hanley, Michael Barenboym

Patent number: 8374702Abstract: A method and apparatus (100) of treating tissue adjacent a bodily conduit using thermotherapy, while preventing obstructions of the bodily conduit due to edema, includes injection of a drug-encapsulated within a heat-sensitive carrier, such as a liposome, within a region of tissue to be treated. The heat produced by the energy-emitting source (110) heats a portion of the tissue surrounding the bodily conduit to a temperature of approximately 43° C. for a time sufficient to destroy the heated portion of the tissue. In addition, the heat produced by the energy-emitting source (110) activates the heat-sensitive carrier to activate the release of the encapsulated drug and the drug targets the tissue to be heated. The focused energy of the energy-emitting source together with the compression acting on the target area can assist in delivering drugs to the target area so that a natural stent has a long term efficacy.Type: GrantFiled: June 14, 2012Date of Patent: February 12, 2013Assignee: Medifocus, Inc.Inventors: John Mon, Alan J.
