摘要:
An apparatus for testing of electrical or physical properties of a material include a single coil sensor mounted adjacent to a sample of the material. Sheet conductance of a wide variety of materials may be measured using the single coil to determine if the material conforms to generally accepted standards for the use to which the material will be put. In some examples, the material is a semiconductor wafer or flat panel. In other examples, the material is the body tissue of a patient. A non-invasive technique using the apparatus is also disclosed for monitoring the health of patient tissue such as musculature, and/or to determine whether healthy circulation is present, by measuring the conductance of the patient tissue in response to a magnetic field applied by the single coil. The single coil may be hand held, or it may be movable using an automated positioning system under computer control.

Novel calcium phosphate core particles, methods of making them, and methods of using them as vaccine adjuvants, as cores, as carriers of biologically active material, and as controlled release matrices for biologically active material are disclosed. The core particles may have a surface modifying agent and/or biologically active material, such as antigenic material or natural immunoenhancing factor, polynucleotide material, or therapeutic proteins or peptides, partially coating the particle or impregnated therein. The core particles have a diameter between about 300 nm and about 4000 nm, more particularly between about 300 nm and about 2000 nm, and even more particularly between about 300 nm and about 1000 nm, are substantially spherical in shape, and have a substantially smooth surface

A suburethral implant for treating stress urinary incontinence (SUI) includes an elongated plate-like member which is slightly curved in transverse cross-section, and a pair of spaced apart arms having hooked ends or barbs which extend from the plate-like member. A device for deploying the suburethral implant for treating SUI includes a vaginal probe for insertion in the vaginal canal of a patient, and a urethra locator probe for the simultaneous insertion in the urethra of a patient. The urethra probe is spaced apart from and overlies the vaginal probe. The vaginal probe includes a wall in which is formed an exit port. A suburethral implant introducer assembly is extendable and retractable through the exit port on the vaginal probe. The introducer assembly has a distal end on which is removably mounted a suburethral implant. The introducer assembly is extendable through the exit port to pierce the vaginal canal wall of the patient in order to position the suburethral implant in proximity to the patient's urethra. The hooked ends or barbs on the arms of the suburethral implant engage the tissue surrounding the patient's urethra and are affixed thereto during deployment of the implant. The introducer assembly is then retracted into the vaginal probe, whereby the implant is released from the introducer assembly and remains affixed to tissue in proximity to the patient's urethra.

摘要:
Novel calcium phosphate core particles, methods of making them, and methods of using them as carriers of biologically active material and controlled release matrices for biologically active material are disclosed. The core particles may have a surface modifying agent and/or biologically active material, such as polynucleotide material partially coating the particle or impregnated therein or both. The particles may be used to carry polynucleotide (or oligonucleotide) material that is complementary to a sequence of mRNA that binds to or ligates with and inhibits the expression of particular genes (by blocking translation of the mRNA sequence). The core particles are substantially spherical in shape, and have a substantially smooth surface.
