  • Patent number: 11020210
    Abstract: There is provided a method for controlling a flow of intestinal contents in the intestinal passageway of a patient's intestines. The method comprises gently constricting (i.e., without substantially hampering the blood circulation in the intestinal tissue wall) at least one portion of the intestinal tissue wall to influence the flow in the intestinal passageway, and stimulating the constricted wall portion to cause contraction of the wall portion to further influence the flow in the intestinal passageway. The method can be used for restricting or stopping the flow in the intestinal passageway, or for actively moving the fluid in the intestinal passageway, with a low risk of injuring the intestines.

  • Patent number: 10691217
    Abstract: A method at a computer system includes obtaining an electronic document comprising document elements, and injecting into the document in association with one of the document elements one or more hotspot attributes, the hotspot attributes defining attributes of a hotspot that is displayable in conjunction with the document element when the document is displayed, the hotspot attributes being associated with predefined physical gestures and respective document actions; such that the hotspot, when displayed as part of a displayed document, indicates that a viewer of the displayed document can interact with the displayed document using the predefined physical gestures (i) performed at a position that overlap a displayed version of the document in a field of view of a camera system and (ii) captured by the camera system, wherein a physical gesture results in a respective document action being performed on the displayed document.

  • Patent number: 10682070
    Abstract: A medical system comprises a probe comprising a terminal distal end. The system further comprises a first coil in the probe and comprises a guide instrument including a terminal distal end and defining a lumen sized to guide the probe. The probe can be inserted through the lumen to reach a worksite. At the worksite, the terminal distal end of the probe is configured to reach at least the terminal distal end of the guide instrument. The system further comprises a sensor embedded in a wall of the guide instrument and comprises processing hardware configured to receive a first induced signal from the first coil and to receive from the sensor an indication of a pointing direction of the guide instrument. The processing hardware is configured to use the first induced signal and the indication of the pointing direction to determine a roll angle of the probe.

  • Patent number: 10674934
    Abstract: An apparatus and a method for determining the position of a medical instrument, particularly for the purpose of medical navigation. In order to use a simple system to provide a relatively inexpensive technique for determining positional information, the position and/or orientation of the medical instrument is determined by ascertaining the same on the basis of position finding operations. Electromagnetic fields are first measured and the results of relative field strength measurements are taken as a basis for ascertaining the direction of a line from a transmitter to a receiver. After this direction information is known, it is used to determine the positional information of the medical instrument.

  • Patent number: 10660542
    Abstract: Systems and methods are provided for identifying or locating a tag within a patient's body that include a probe that transmits synchronized electromagnetic signals, e.g., RF energy, and optical signals, e.g., infrared light pulses into the patient's body, whereupon the tag converts the optical signals into electrical energy to open and close a switch in the tag to modulate signals, e.g., backscatter signals, transmitted by the tag in response to the electromagnetic signals. For example, the tag may include photodiodes coupled to the switch that transforms the optical signals to alternately short the antenna to modulate the backscatter signals. Alternatively, the tag may include a smart circuit that harvests electrical energy from the optical signals to power the smart circuit and/or modulate the backscatter signals, e.g., to include data related to the tag and/or alternate the tag between an information mode and a distance mode.
