  • Patent number: 6810277
    Abstract: A method for removing motion artifacts from devices for sensing bodily parameters and apparatus and system for effecting same. The method includes analyzing segments of measured data representing bodily parameters and possibly noise from motion artifacts. Each segment of measured data may correspond to a single light signal transmitted and detected after transmission or reflection through bodily tissue. Each data segment is frequency analyzed to determine up to three candidate peaks for further analysis. Each of the up to three candidate frequencies may be filtered and various parameters associated with each of the up to three candidate frequencies are calculated. The best frequency, if one exists, is determined by arbitrating the candidate frequencies using the calculated parameters according to predefined criteria. If a best frequency is found, a pulse rate and SpO2 may be output. If a best frequency is not found, other, conventional techniques for calculating pulse rate and SpO2 may be used.

  • Patent number: 5529076
    Abstract: Presbyopia and hyperopia are treated by a method which increases the amplitude of accommodation by increasing the effective working distance of the ciliary muscle in the presbyopic eye. The effective working distance of the ciliary muscle can be increased by expanding the sclera in the region of the ciliary body. This expansion is accomplished by suturing to the sclera a relatively rigid band having a diameter slightly greater than that of the sclera in the region of the ciliary body, by weakening the sclera overlying the ciliary body, by surgical procedures or treatment with enzymes, heat or radiation, whereby intraocular pressure expands the weakened sclera, or by surgical alloplasty. The effective working distance of the ciliary muscle can also be increased by shortening the zonules by application of heat or radiation, by repositioning one or both insertions of the ciliary muscle or by shortening the ciliary muscle.

  • Patent number: 5514180
    Abstract: Disclosed are prosthetic devices for insertion into intervertebral disc spaces after the removal of an intervertebral disc or after a corpectomy. Specifically, intervertebral devices having fixed shapes for accommodating the defined surface contours of vertebral endplates are disclosed. Also disclosed are intervertebral devices formed of osteoinductive materials, such as bone growth factors, to facilitate bone growth. A method for quantitatively determining the three-dimensional morphology of vertebral surfaces, particularly vertebral endplates, is also disclosed.

  • Patent number: 5312384
    Abstract: An incontinence device and applicator therefor. The incontinence device comprises a generally tubular, soft latex bag which tapers to an opening at an upper end thereof. An area adjacent said opening is adapted to be adhesively attached to the tissue overlying the anal sphincter of a patient. The applicator is adapted to fit within the incontinence device. It includes an elongated handle and a head attached thereto, the head being configured to fit against the anal area of the user and bring the attachment of the device to bear against the anal tissue for adhesive attachment thereto. The head includes an oval, ring-shaped bearing surface and means for adjusting the size of the bearing surface so that the device may be used on patients displaying a wide range of anatomical variation. A method of making the incontinence device by vacuum molding is also disclosed.
