  • Publication number: 20240058087
    Abstract: Certain aspects relate to systems and techniques for medical robotic systems that leverage a versatile, open kinematic chain together with a set of medical-procedure-specific software-controlled actuation constraints in order to perform a variety of medical procedures. The robotic system can be operated in a first mode by identifying a remote center and constraining the actuation of motorized joints to maintain intersection of at least an insertion axis with the remote center. The robotic system can be operated in a second mode by identifying a virtual rail position and constraining the actuation of motorized joints to maintain alignment of the insertion axis along the virtual rail.

    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.

  • Patent number: 11784999
    Abstract: Embodiments are directed to credential management for distributed services. A plurality of mesh agents for an overlay network may be provided such that the overlay network may be employed to provide a secure tunnel between a client and a resource server. If client request that requires user credentials is provided to a mesh agent associated with the resource server, credential instructions may be provided to the mesh agent and the credential instructions may be employed to determine credential information that enables access to the resource server. The mesh agent may be employed to communicate the client request and the credential information to the resource server; determining a response to the client request from the resource server; employing the mesh agent to receive a response to the client request from the resource server and forwarded to the client over the overlay network.

  • Publication number: 20230309985
    Abstract: The present invention features a sensor implant that can adhere to bone. The sensing device is capable of sensing bone strains and reporting them as well as loads passing through bone for extended periods of time. The sensor implant can also be used to monitor bone growth for bone segmental repair of long bones or to monitor changes in bone characteristics of patients with osteoporosis. The present technology has the potential to give physicians the ability to predict when a patient with osteoporosis has an impending fracture and thus be able to intervene and prevent further damage.
