Patent number: 11253166Abstract: This invention relates to a method of catheter and radiating coil location in a human body. In particular, when a radiating coil is used in conjunction with a catheter, a coil locating device can be used to determine the distance the coil is from the device and its depth in the patient's body. A display is provided that shows both a reference image of a portion of a non-subject body and an image of the coil located on the display with reference to the reference image. This is achieved by locating the coil-locating device on a predetermined landmark on the patient's body. The coil and its signal wires can be incorporated into a stylet, guide wire or a catheter.

Patent number: 11109806Abstract: A three dimensional imaging system includes a first laser emitting light at a first wavelength, and a scanner for scanning the laser light in a pattern on the target area. A photo detector receives light reflected from the target area as a contrasted vein image, resulting from differential absorption and reflection therein of the first wavelength of light. The intensity of the first laser is incrementally increased, and the photo detector thereby receives a plurality of contrasted vein images, each being at incrementally distinct depths beneath the target skin surface. Image processing is performed on the plurality of vein images to successively layer the veins in the images according to their depth, to create a single processed vein image. A second laser emitting a second wavelength of light is used in combination with the scanner to project the processed vein image onto the target area to overlay the veins therein.Type: GrantFiled: August 29, 2017Date of Patent: September 7, 2021Assignee: AccuVein, Inc.Inventors: Ron Goldman, Fred Wood, Stephen P.
