Publication number: 20100063346Abstract: In some embodiments, the present disclosure provides methods for stimulating a subject's immune system. Particular methods provide a tumor specific immune response by injecting a tumor with a magnetorheological fluid and applying a magnetic field to the tumor. The immune response can be used to treat disseminated tumors or metastatic cells. Further methods induce a general immune response, such as by treating a section of tissue, such as healthy tissue, with a magnetorheological fluid and applying a magnetic field to the treated tissue. The immune response can be used to treat illness or disease or to enhance the effect of a therapeutic agent. In particular examples, the disclosed methods are used to enhance the effect of immuno stimulants. Also provided are methods for causing necrosis of a cell mass, such as a tumor, by injecting a magnetorheological fluid into a section of tissue and applying a magnetic field to the tissue.Type: ApplicationFiled: May 17, 2007Publication date: March 11, 2010Inventors: William J.

Patent number: 7422092Abstract: A damper/strut that can provide variable damping and spring energy storage and dissipation. One embodiment includes an adjustable magnetorheological damper and a mechanically adjustable fluid spring in association with an internal accumulator. A combination of internal and external electromagnets generate the magnetic fields required to activate internally maintained magnetorheological material so that its apparent viscosity undergoes the desired change for a given disturbance. By controlling the strength of the magnetic fields generated in the device, the damping capacity and energy storage of the compressible liquid spring can be affected to provide a semi-active damper that can both dissipate and store energy. The proposed devices can be coupled with a sensor feedback and a control system to provide fast and accurate response force for a variety of engineering applications.Type: GrantFiled: July 7, 2004Date of Patent: September 9, 2008Inventors: Gregory Hitchcock, Faramarz Gordaninejad

Patent number: 7364022Abstract: Variably controllable motion-damping devices are disclosed that utilize a magneto-rheological fluid (MRF). One configuration of such a device includes a first valving region and a second valving region connected to the first valving region. Between the first and second valving regions is a plate having a first surface adjacent the first valving region and a second surface adjacent the second valving region. At least one of the first and second surfaces is treated to impart a significantly increased shear yield stress to columnized MRF particles passing over the surface, compared to an otherwise similar untreated surface. An MRF is contained in the first and second valving regions such that the MRF can flow through the first and second valving regions. Motion of a first object relative to a second object is damped by causing flow of MRF through the first and second valving regions. A magnet produces a magnetic field within at least one of the valving regions.Type: GrantFiled: April 4, 2005Date of Patent: April 29, 2008Assignee: University of NevadaInventors: Faramarz Gordaninejad, Xiaojie Wang, Gregory Hitchcock, Barkan M.
