  • Patent number: 6168563
    Abstract: A system and method is described that enables a health care provider to monitor and manage a health condition of a patient. The system includes a health care provider apparatus operated by a health care provider and a remotely programmable patient apparatus that is operated by a patient. The health care provider develops a script program using the health care provider apparatus and then sends the script program to a remotely programmable patient apparatus through a communication network such as the World Wide Web. The script program is a computer-executable patient protocol that provides information to the patient about the patient's health condition and that interactively monitors the patient health condition by asking the patient questions and by receiving answers to those questions. The answers to these health related questions are then forwarded as patient data from the remotely programmable patient apparatus to the health care provider apparatus through the communication network.

  • Patent number: 6168564
    Abstract: In an ultrasonic imaging system, a transducer array structure, preferably a linear one-dimensional array on a catheter, is provided wherein the direction of a beam is controlled by a preselected, linear delay profile implementing a linear portion of a beam forming equation so that the array is effectively curved electronically. Beam forming is effected independently of the steering. An active aperture is provided by which a beam is steered according to linear array techniques. The active aperture comprises selected adjacent subsets of transducer elements of the array structure. The delay profile may be implemented by delay lines to each transducer element or by any preselected delay elements whereby the flatness or curvature of the array structure is matched and so that beam steering can be implemented by simple translation of the aperture along the transducer array. The pitch or separation between the transducer elements may be uniform or varied.

  • Patent number: 6168590
    Abstract: A method for permanently removing hair utilizes the hair shaft and hair ducts to transmit light into the tissue sustaining the hair follicle, thereby permanently destroying or modifying the tissue in a manner which desirably mitigates hair growth. The method includes the steps of covering the patient's skin area with a high reflectance substance so as to substantially protect all skin components other than those sustaining the hair. The hair is optionally shaved or pulled out, and then the skin is illuminated with either a large-area electromagnetic radiation field for simultaneous destruction of multiple hair-follicles, or alternatively with a tightly-focused beam which destroys one hair at a time. Optionally, the beam may be rapidly scanned so as to destroy single hairs quickly in succession. The surrounding skin region is left substantially free of injury. This mitigates pain and enhances post hair removal healing.

  • Patent number: 6168606
    Abstract: A single-use, spring driven lancet is described. The device is precooked during assembly so that the user needs only to remove the safety cap prior to use. A concave trigger button with direct up and down motion releases the spring, causing the tip of the lancet to strike the subject's finger. A thin plastic fiber connection between the pull-tab and the needle safety cap prevents any compressive force from being applied to the drive spring, which effectively prevents recocking of the device.
