  • Patent number: 10555723
    Abstract: A control method, computer readable medium, and imaging apparatus for diagnosis being configured to create a tomographic image are disclosed. The method includes obtaining ultrasound line data oriented in a radial direction from a rotation center based on a signal obtained by executing the scanning; obtaining optical interference line data oriented in a radial direction from the rotation center based on a signal obtained by executing the scanning; identifying a line or a group of lines having a same feature out of each line data of the ultrasound tomographic image and the optical tomographic image; determining segmentation positions for a bundle of lines corresponding to at least a single frame included in each tomographic image from each line data of the ultrasound tomographic image and the optical tomographic image with respect to the identified line or group of lines; and creating a tomographic image from the determined bundle of lines.

  • Patent number: 10548659
    Abstract: A needle with multiple injection ports is used in connection with a high-pressure injection system to infuse a treatment solution into a treatment area below the dermis of the skin. The needle has multiple tines that extend outwardly from the injection ports while inside the treatment area to disrupt tissue in the treatment area and to create multiple pathways of infusion. The tines are withdrawn and the needle is partially withdrawn, and solution is injected from the needle into the treatment area at high pressure to infuse the tissue within the treatment area. The burst, infusion, and a treatment such as an energy or third solution may be interleaved and repeated multiple times.

  • Patent number: 10548563
    Abstract: A system for highlighting an instrument in an image includes a probe (122) for transmitting and receiving ultrasonic energy and a marker device (120) configured to respond to a received ultrasonic signal and emit an ultrasonic signal after a delay. A medical instrument (102) includes the marker device. A control module (124) is stored in memory and configured to interpret the ultrasonic energy received from the probe and from the marker device at the probe to determine a three dimensional location of the medical instrument to highlight a position of the marker device in an image.

  • Patent number: 10537286
    Abstract: A catheter having a distal assembly with multiple spines with proximal ends affixed to the catheter and free distal ends. The spines have different lengths so distal ends of the spines trace different circumferences along an inner tissue surface of a tubular region to minimize risk of vein stenosis. The spine lengths can be configured so that the distal ends trace a helical pattern. The distal assembly may have a plunger which deflects the spines when moved longitudinally relative to the distal assembly. The catheter may include a second distal assembly distal of a first distal assembly wherein the first and second distal assemblies are separated by a fixed distanced or an adjustable distance.
