    摘要: A new class of biosensors and methods for making and using same are disclosed. The biosensors are multi-layered membrane composites, where at least one layer is prepared by the layer-by-layer process and at least one layer is responsive to changes is a property of a biological system such as changes in the concentration of an atom, ion, molecule or molecular assembly. Because the biosensors are multi-layered, a single biosensor is capable monitor a number of different properties of a biological system simultaneously. The biosensors are monitored by systems that impinge an excitation waveform on the biosensors and analyze a reflected and/or a transmitted resultant waveform. Additionally, the biosensors can be associated with field activated electronic components so that implantable, self-contained analytical devices can be constructed and monitored by field generators, where data is transmitted to an analyzer after field activation.

    摘要: Disclosed is a method for delivering energy to a tissue. The method includes providing an apparatus which includes an energy delivery component and an inflatable member disposed around the energy delivery component. At a minimum, the inflatable member is constructed of a flexible inner wall and a flexible outer wall, which, taken together, enclose a cavity therebetween. The inflatable member is expanded such that the inflatable member's outer wall contacts the tissue's surface. Cooling fluid is disposed in the cavity, and energy is delivered to the energy delivery component so that at least a portion of the energy delivered to the energy delivery component passes through the inflatable member's inner wall, through the cooling fluid disposed in the cavity, through the inflatable member's outer wall, and into the tissue. Various apparatus suitable for use in delivering energy to tissues are also disclosed, as is a method for treating GERD or otherwise reducing reflux of a subject's stomach contents into the subject's esophagus.

    摘要: An optoacoustic apparatus is disclosed which includes a radiation source of pulsed optical radiation and a probe having a front face to be placed in contact with a tissue site of an animal body. The probe further includes an optical fiber terminating at the surface of the front face of the probe and connected to a pulsed laser. The front face of the probe also has mounted therein or thereon a piezoelectric transducer for detecting an acoustic response to the radiation pulses connected to a processing unit which converts the transducer signal into a measure of hemoglobin concentration and/or hematocrit of blood.

    摘要: A catheter capable of both sensing myocardial electrical activity and delivering ablating energy within myocardial tissue is disclosed. The catheter comprises electrodes on the outer sheath and contains a movable fiber optic cable that can be percutaneously advanced beyond the catheter body and into the myocardium for myocardial heating and coagulation, or modification of tissues responsible for cardiac arrhythmias. The fiber optic tip is designed to diffuse ablating energy radially to ablate a larger volume of tissue than is possible with a bare fiber optic tip. In addition, the tip is treated so that energy is not propagated in a forward direction, thus helping to prevent unwanted perforation of the heart tissue. Also disclosed is a method of cardioprotection from ischemia comprising inducing local hyperthermia in heart tissue.

    摘要: Methods for measuring analyte concentration within a tissue using optical coherence tomography (OCT). Radiation is generated, and a first portion of the radiation is directed to the tissue to generate backscattered radiation. A second portion of the radiation is directed to a reflector to generate reference radiation. The backscattered radiation and the reference radiation is detected to produce an interference signal. The analyte concentration is calculated using the interference signal.
