  • Patent number: 10906180
    Abstract: A method and system to monitor and autonomously configure an intravascular assembly without medical staff involvement or presence. In this solution, a robotic device is associated with an intravascular assembly, which has tubing through which fluids are delivered intravenously. Monitoring of the tubing is initiated. In response to the monitoring, an errant flow through the tubing is detected; typically, the errant flow results from one of: a kink or twist in the tubing, an air bubble in the tubing, an occlusion or clot in the tubing, and pressure variations. In response to detecting the errant flow, and in advance of an audible alarm being generated in association with the intravascular assembly, a command is then issued to the associated robotic device. The command is configured to initiate, by the robotic device, physical engagement with and mechanical manipulation of the tubing, thereby remediating the errant flow automatically.

  • Patent number: 10898686
    Abstract: Actuators for steerable medical devices are disclosed that not only deflect or steer a portion of a medical device (e.g., a distal portion of a catheter shaft), but also include mechanisms for actively returning the deflected portion of the medical device to an initial configuration (e.g., straight or substantially straight). These active return-to-straight mechanisms may return a catheter shaft from a deflected configuration to a substantially straight configuration throughout a medical procedure, may employ one or more tension members extending along the catheter shaft, and may comprise a gross return actuator and a fine return actuator. For example, the gross return actuator may be configured to partially reverse the deflection of the distal portion of the catheter; and the fine return actuator may be configured to continue reversing the deflection. The gross return actuator may automatically trigger or actuate (mechanically or electromechanically) the fine return actuator.

  • Patent number: 10869840
    Abstract: Embodiments provide swallowable devices, preparations and methods for delivering viable cells (VC) into the GI tract including GI wall tissue or other tissue site. Particular embodiments provide a swallowable device such as a capsule for delivering VC into an intestinal wall or other site. The VC can be contained within a tissue-penetrating shell disposed in the capsule that protects the VC as they pass through the GI tract until they are inserted into GI tract tissue or other location. The shell desirably has shape, size and material consistency to be contained in a swallowable capsule, delivered from the capsule into solid tissue by the application of force on the shell and biodegrade within the solid tissue to release the VC into the tissue. Within the shell or other structure the VC can be maintained in a viability-sustaining gel that preserves the viability of the VC for selected time periods.
