    摘要： A method of diagnosing a patient is carried out by delivering an aerosolized dose of a radioactive formulation to a patient and making a ventilation image of radioactive material deposited in the lung. This image is compared with a separately generated image (perfusion image) taken after injecting radiolabled particles into the pulmonary arterial circulation. Devices, packaging and methodology for creating aerosols are provided which allow for efficient and repeatable delivery of radioaerosols to the lungs of a patient. Devices may be plug-in units or hand-held, self-contained units which are automatically actuated at the same release point in a patient's inspiratory flow cycle. The device is loaded with a container of a radioactive formulation such as .sup.99m Tc-labelled diethylene-triamine pentaacetic acid (DTPA). Actuation of the device forces the radioactive formulation through a porous membrane of the container which membrane has pores having a diameter in the range of about 0.25 to 6.0 microns. The container includes radioactive shielding in the form of a lead coating and/or a lead surrounding packet. The porous membrane is positioned in alignment with a surface of a channel through which a patient inhales air.

    摘要： Night driving eyeglasses include an illuminating color band extending upwardly from the bottom of the lens to cover about 50 per cent to about 75 per cent of the surface area of the lens and a glare-reducing color band extending downwardly from the top of the lens to cover about 25 per cent to about 50 per cent of the surface area of the lens, with a distinct interface between the color bands. The glasses further include a nonreflective coating made from a plurality of layers of magnesium oxide selectively applied to a surface of the lenses of the glasses. Preferably, the distinct interface is located about 5 mm above the top of the wearer's pupil. The color bands and the nonreflective coating all cooperate to equalize the illumination of the wearer's entire field of vision.

    摘要： A system and method places a percutaneous gastrostomy device into a body cavity of a patient using a magnetic gastrostomy tube and a medical detection sensing device. The magnetic gastrostomy tube has a ferromagnetic element attached to its distal end. Various embodiments allow a needle to be passed from the magnetic detection sensing device outside the patient toward a magnetic gastrostomy tube inside the patient or, alternatively, from the magnetic gastrostomy tube inside the patient toward the magnetic detection sensing device outside the patient. After a needle makes a hole between the outside of the patient and the body cavity, a medical wire may be passed through the hole, and the medical wire can then be used to place the percutaneous gastrostomy device.

    摘要： A percutaneous treatment catheter comprises a canopy (12) having a treatment side adapted to provide at least one of a variety of treatments to a first tissue layer and a protection side that protects adjacent tissue from the treatment. Treatments include, but are not limited to, those that act to cause an inflammatory response resulting in forming scar tissue that would tend to form adhesions, such as, but not limited to, for the treatment of pleural effusions. In an embodiment, a treatment catheter comprises a shaft (20) having a shaft and a treatment head (10) disposed about the shaft distal end, the treatment head adapted to present a low profile in a closed state and a broad profile in a 10 deployed state, the treatment head adapted to percutaneously treat one of first and second tissue layers and protect the other of the first and second tissue layers from the treatment.
