  • SYSTEMS AND METHODS FOR ADJUSTING REMOTE CENTER DISTANCES IN MEDICAL PROCEDURES
    Publication number: 20210030501
    Abstract: Systems and methods for adjusting remote center distances in medical procedures are provided. In one aspect, a robotic medical system includes a first robotic arm including a first instrument driver, wherein the first instrument driver is configured to manipulate a first tool that passes through a first cannula, and a second robotic arm including a second instrument driver, wherein the second instrument driver is configured to manipulate a second tool that passes through a second cannula. The first tool is configured to rotate about a first remote center of motion and the second tool is configured to rotate about a second remote center of motion. A first remote center distance between the first robotic arm and the first remote center of motion is different from a second remote center distance between the second robotic arm and the second remote center of motion.

  • Transparent Multiplexing of IP Endpoints
    Publication number: 20210029035
    Abstract: Allowing a network function (such as a router, firewall or SD-WAN endpoint) or service chain of network functions to transparently access a network uplink, while also allowing a set of management entities to access the same link without interference or configuration. To the extent that a conflict arises between ports allocated to the management functions and to the network functions, the relevant port is automatically removed from use by management functions and allocated to network functions to end the conflict.

  • Gravity Infusion Control System
    Publication number: 20200360604
    Abstract: A monitoring device provided for monitoring the delivery of fluids through a drip chamber. The device includes an electromagnetic radiation source and a radiation detector. A weight detector is positioned to determine the weight of a fluid reservoir over time, and the detector is positioned with respect to the drip chamber to detect drops falling through the drip chamber. A processor is coupled to the radiation detector and the weight detector to determine flow rate, and is further coupled to a flow restrictor to selectively increase or decrease flow based on the determined flow rate.

  • SYSTEMS AND METHODS FOR ALIGNING INPUTS ON MEDICAL INSTRUMENTS
    Publication number: 20200297437
    Abstract: Certain aspects relate to systems and techniques for aligning inputs on medical instruments. In one aspect, the method includes receiving, at a data reader of the instrument drive mechanism, alignment data from the tool when the tool is positioned within a threshold distance of the data reader. The tool include one or more inputs and one or more pull wires configured to be actuated by output shafts of the instrument drive mechanism via the one or more inputs. The method also includes receiving, at a processor, the alignment data from the data reader, and rotating, via the processor, the one or more output shafts of the instrument drive mechanism into alignment with the one or more inputs of the tool based on the alignment data. Each of the output shafts is configured to mechanically couple with a corresponding one of the inputs of the tool.

  • DEVICES AND METHODS FOR THE TREATMENT OF HEART FAILURE
    Publication number: 20200245991
    Abstract: A device for treating heart failure in a patient. The device comprising a body, at least one passage through the body, at least one one way valve in the passage and a mounting means adapted for mounting the body in an opening provided in the patient's atrial septum. In use, the device is oriented such that, when the patient's left atrial pressure exceeds the patient's right atrial pressure by a predetermined amount, the one way valve(s) opens to allow blood flow through the passage(s) from the left atrium to the right atrium to thereby reduce the left atrial pressure.
