Patent number: 7729778Abstract: Method, system and apparatus for monitoring target tissue temperatures wherein temperature sensors are configured as passive resonant circuits each with a unique resonating signature at monitoring temperatures extending below a select temperature setpoint. The resonant circuits are configured with an inductor component formed of windings about a ferrite core having a Curie temperature characteristic corresponding with a desired temperature setpoint. By selecting inductor winding turns and capacitance values, unique resonant center frequencies are detectable. Temperature monitoring can be carried out with implants at lower threshold and upper limit temperature responses. Additionally, the lower threshold sensors may be combined with auto-regulated heater implants having Curie transitions at upper temperature limits.Type: GrantFiled: September 30, 2005Date of Patent: June 1, 2010Assignee: Calfacior Corp.Inventors: Philip E.

Patent number: 7567843Abstract: System method and apparatus for accurately carrying out the in situ heating of a targeted tissue. Small implants are employed with the targeted tissue which exhibit an abrupt change of magnetic permeability at an elected Curie temperature. The permeability state of the implant is monitored utilizing a magnetometer. The implants may be formed as a setpoint temperature determining component combined with a non-magnetic heater component to enhance the tissue heating control of the system. With the system, a very accurate quantum of heat energy can be supplied to a neoplastic lesion or tissue carrying infectious disease so as to maximize the induction of heat shock proteins. The system also may be utilized in conjunction with non-magnetic arterially implanted stents for the hyperthermia therapy treatment of restenosis and in conjunction with the mending of boney tissue.Type: GrantFiled: January 14, 2005Date of Patent: July 28, 2009Assignee: Apsara Medical CorporationInventors: Philip E.

Publication number: 20020106375Abstract: A new factor, Factor C, is produced by the activated-expanded autologous cells of cancer patients, HIV-1 infected patients, CFS patients, healthy patients, etc. Factor C has a molecular weight of about 70,000 to 80,000 daltons, is heat stable, has an amino acid sequence that is absent from the National Center for Biotechnology Information database, and whose amino acid sequence is not homologous to TNF family ligands. Factor C is derived from CD4 cells in a much greater quantity than from CD8 cells, and is derived from lymph cells in a greater quantity than from PBL cells. A double activation and expansion (activation-expansion) process using immobilized and soluble anti-CD3 mAb makes such Factor C. Factor C appears to inhibit transcription in virally-infected and tumor cells, and stimulates the proliferation of normal lymphocytes.Type: ApplicationFiled: November 30, 2000Publication date: August 8, 2002Inventors: Pierre L.

Patent number: 5705162Abstract: The present invention broadly relates to a therapeutic agent effective in mitigating disease associated with Feline Leukemia Virus (FeLV) in a feline infected with FeLV. A feline is an animal of the family Felidae. The novel therapeutic agent is composed of feline excised lymph nodes which have been subjected to mitogenic stimulation for their expansion dispersed in a pharmaceutically-acceptable carrier. Mitogenic stimulation conditions include culturing the excised lymph nodes in the presence of Interleukin-2. Optionally, culture conditions can include the presence of allogeneic or autologous FeLV tumor. The inventive therapeutic agent is prepared by excising lymph nodes from a feline infected the FeLV, mitogenically stimulating said excised lymph nodes for their expansion, and administering to the infected feline the expanded lymph nodes. Multidose regimens can be used as is necessary or desirable in convenient fashion.Type: GrantFiled: October 16, 1995Date of Patent: January 6, 1998Assignee: Parhelion CorporationInventors: Richard G.

Patent number: 4666659Abstract: A shipping and transport cask for spent nuclear fuel elements. The cask includes a cylindrical cask body having an outer shell and a concentric inner tube. Four quadrant baskets are mounted within the inner tube. Each quadrant basket includes radial and peripheral walls of high thermal conductivity material. A plurality of fuel element-receiving modules and an inner quadrant heat conducting member are mounted within the quadrant baskets. The peripheral walls of the quadrant baskets are held firmly against the inner wall of the body by shims inserted between the radial walls of adjacent quadrant baskets. During assembly, the quadrant baskets are initially forced outwardly against the inner wall by means of expandable spreaders. The cask also includes removable trunnions and primary and secondary external fluid chambers filled with a neutron-attenuating fluid.Type: GrantFiled: October 25, 1983Date of Patent: May 19, 1987Assignee: Mitsubishi Heavy Industries, Ltd.Inventors: Elmer C.
