  • Patent number: 11523732
    Abstract: A compliant surgical device such as a flexible entry guide employs tendons to operate or steer the device and attaches asymmetric or constant force spring systems to control tension in the tendons. As a result, the surgical device can be compliant and respond to external forces during a surgical procedure without rapidly springing back or otherwise causing a reaction that damages tissue. The compliance also permits manual positioning or shaping of the device during or before insertion for a surgical procedure without damaging the tendons or connections of the tendons within the device or to a backend mechanism.

  • Patent number: 11406461
    Abstract: A delivery system and methods are disclosed for delivering a material to a target site. A delivery instrument is coupled to a robotic manipulator and comprises a delivery device having a distal tip comprising an opening deliver the material to the target site through the opening. A navigation system tracks the delivery device and the target site and generates position signals. One or more controllers are in communication with the robotic manipulator and the navigation system and define a virtual boundary associated with the target site, wherein the virtual boundary is utilized to constrain movement of the delivery device. The one or more controllers control one or more joint motors of the robotic manipulator to move the distal tip of the delivery device with respect to the virtual boundary based on the position signals from the navigation system.

  • Patent number: 11395887
    Abstract: A device for delivering a compound to the olfactory region of the nasal cavity includes an actuator body and a tip that removably couples to the actuator body. The actuator body includes a propellant channel in fluid communication with a propellant canister. The tip includes an exit channel, an inlet interface, one or more grooves, and an outlet orifice. The exit channel extends between a proximal end and a distal end of the tip. The inlet interface is positioned about a distal end of the exit channel, and the inlet interface couples to a compound container containing the compound. The grooves are positioned about the inlet interface and direct propellant from the propellant channel into the compound container, thereby agitating and entraining the compound in the compound container with the released propellant. The compound and the propellant then travel through the exit channel and out the outlet orifice.

  • Patent number: 11337684
    Abstract: An occluder has a first disk-shaped structure with a grid, wherein the first disk-shaped structure is woven from at least two groups of braided wires, and the two groups of braided wires are crossed to form multiple rings of crossing points. A blocking membrane is also arranged in the disk-shaped structure, with an edge of the blocking membrane connected to the outermost ring of crossing points of the multiple rings of crossing points through a sewing wire, and the number of crossing points in the outermost ring of crossing points sewn with the blocking membrane is smaller than the number of all the crossing points in the outermost ring of the crossing points. The occluder can reduce the possibility of the phenomenon where the edge of the blocking membrane cannot abut against a disk face edge of the occluder, thereby improving the occlusion effect of the occluder.
