  • Patent number: 8152742
    Abstract: A medical device with a corrugated shaping ribbon is provided. The corrugated shaping ribbon for the medical device, which may be provided in the form of a guide wire or catheter, specifically a crossing guide wire or catheter, provides a mechanism by which energy can be stored as the distal tip of the medical device engages a lesion or other area of occlusion within a blood vessel. By storing such energy and continuing to apply force, eventually the distal tip extends thereby releasing the stored energy and allowing the distal tip to advance or cross through the lesion.

  • Patent number: 5820562
    Abstract: A skin allergy test device includes a skin allergy test bar and an antigen container. The skin allergy test bar includes a finger grip, an integral cover having a sealing plug portion, an elongated stem extending therefrom, and a plurality of step-shaped punctures, wherein each puncture has a flat step to act as a stop and an integral sharp tip projecting out from the flat step. Each sharp tip has a length shorter than the thickness of the epidermis layer of the skin of human beings such that each puncture will not penetrate the epidermis layer of the skin of human beings due to the flat step of the punctures acting as a stop during a skin allergy test.

  • Patent number: 5795306
    Abstract: A bodily state detection apparatus comprising a CCD camera, an infrared LED device, a pickup image memory, a pupil extraction circuit and a bodily state judgment circuit. The CCD camera inputs images of a predetermined area including the subject person's face. The infrared LED device illuminates the subject person in such a way that the optical axis of the camera and the direction of the illumination coincide with each other. The pickup image memory stores temporarily the output data of the CCD camera. The pupil extraction circuit extracts the subject person's pupil position from the pickup images. The bodily state judgment circuit judges the subject person's bodily state by use of the result of pupil extraction performed by the pupil extraction circuit.

  • Patent number: 5779648
    Abstract: An instrument for obtaining tissue samples from a site deep within the body. The instrument has an elongated proximal portion that is constructed to follow a long, torturous path to the site and a distal end constructed to remove a tissue sample from the body, including tissue specimens, polyps or the like. The instrument is constructed to take multiple biopsy samples without being withdrawn from the body by including a device body defining a storage space along the axis of the device suitable for storage of multiple, successively taken samples. The instrument includes a sampling assembly having a cutting member, constructed such that it can be actuated in a first, rotary motion to take a tissue sample from the body and a second, axial motion for disposing the sample axially into the storage space.

  • Patent number: 5776081
    Abstract: Devices and methods for measuring the weakness of body lumens, and in particular, urethral sphincters and similar valves, are disclosed. In one embodiment of the invention, a catheter with a hollow fluted distal end can be inserted into a lumen. The hollow fluted distal end of the catheter is then expanded into an enlarged configuration. The measurement of resistance to withdrawal of the catheter in the enlarged configuration provides an indication of weakness of the lumen. In one aspect of the invention, the catheter is inserted into a bladder via the urethral sphincter and the weakness of the urethral sphincter is measured. In another aspect of the invention, a device for measuring weakness of a body lumen, such as a urethral sphincter and similar valves, can consist of a catheter with a hollow fluted distal end having of an array of wings, and an expanding means for radially expanding the wings into an enlarged configuration.

  • Patent number: 5776080
    Abstract: The present invention is a device and method for controlling longitudinal movement of a tube relative to a shaft slidably disposed within the tube, especially in the catheterization of a patient. An operative segment on the shaft cooperates with an ancillary tool to create a coupling force field between the shaft and the tool. The tube can then be moved over the shaft while the coupling force field operates through the tube to restrict the movement of the shaft. In the preferred embodiment, the shaft is a guide wire and the tube is a catheter with a lumen for slidably receiving the guide wire, while the coupling force field is created magnetically. In one embodiment, the operative segment is borne on a short guide wire extension which is selectively securable to a standard guide wire.

  • Patent number: 5741217
    Abstract: Biofeedback monitoring and training of a subject using a computer and a computer mouse in the workplace is achieved by monitoring the galvanic skin response (GSR) of the subject every time he or she uses the mouse and by implementing a predetermined course of action on the computer monitor when measured GSR levels are outside of predetermined upper and lower limits. Biofeedback apparatus for implementing this technique includes a computer mouse with electrodes on the exterior surface of the mouse. When the user makes physical contact with two or more electrodes on the mouse, a very small electrical current is conducted by the subject's skin and is measured. The measured value is transmitted to the computer over a serial communication cable. The mouse otherwise functions as a conventional computer mouse. Software in the computer uses the GSR measurement and implements a predetermined course of action, such as a relaxing message with visual images and soft music.

  • Patent number: 5634472
    Abstract: A determination is quantitatively made of the severity of pain exhibited at a specified area on an animal by determining the magnitude of cooling required at the area of pain in order for the pain to be masked or made to disappear. The amount of cooling required for pain disappearance is considered directly related to the severity of the pain. Hence, by measuring the temperature depression required to mask the pain in a patient, an examiner can determine just how serious is the pain, and additionally provide guidance in the selection of a specific medicine. There is always some finite temperature depression required for true pain to disappear. Should the patient alleges that no pain relief is encountered by the cooling of the painful area, the examiner considers that the patient is faking his pain.

  • Patent number: 5573007
    Abstract: A gas-column pressure measuring catheter which is insertable into a mammalian body for purposes of transmitting pressure changes from a location within the mammalian body to a pressure sensor which is either incorporated into, or connected to, the catheter. In a preferred embodiment, the gas-column pressure measuring catheter comprises an elongate catheter body having a gas-filled lumen extending longitudinally therethrough, and a gas-filled membrane-walled chamber positioned on the catheter body in communication with the gas-filled lumen such that pressure changes exerted against the outer surface of the membrane-walled chamber will result in the transmission of pressure changes through the gas-filled catheter lumen. The gas-filled membrane-walled chamber may be located on the side wall of the catheter body, or may be located on the distal end of the catheter body.
