  • Patent number: 11925332
    Abstract: Certain aspects relate to percutaneous sheaths for medical procedures as well as to related systems and methods. For example, a system for performing a percutaneous assisted medical procedure can include a percutaneous sheath. The percutaneous sheath can include a first conduit for providing aspiration into the kidney and a second conduit for passing a catheter into the kidney. The system can also include an aspiration catheter configured to be inserted into the kidney through the second conduit of the percutaneous sheath. A fluidics system can include an irrigation source comprising a pump and an aspiration source comprising a vacuum. The irrigation source can be connected to a fluid inlet of the percutaneous sheath that is connected to the first conduit. The aspiration source can be connected to the aspiration catheter.

  • Publication number: 20210393338
    Abstract: Methods, systems, and devices for controlling a medical instrument are discussed herein. For example, image data can be received from a first instrument that is configured to access an anatomical site via a first access path. The image data can be representative of the anatomical site and a second instrument that is configured to access the anatomical site via a second access path. A visual representation of the image data can be displayed in a user interface and a first directional input signal can be received from an input device. An orientation of the first instrument relative to the second instrument can be determined. Movement of the second instrument can be controlled based at least in part on the first directional input signal and the orientation of the first instrument relative to the second instrument.

  • Publication number: 20210330309
    Abstract: A method of managing fluid conditions in a patient involves advancing at least one medical instrument into a target organ of a patient, the at least one medical instrument comprising an irrigation channel and an aspiration channel, coupling the at least one medical instrument to an irrigation fluid source, providing irrigation from the irrigation fluid source into the target organ through the irrigation channel of the at least one medical instrument, determining an irrigation pressure limit based at least in part on one or more case-specific parameters, providing irrigation into the target organ through the irrigation channel, and limiting the irrigation based at least in part on the determined irrigation pressure limit.

  • Patent number: 10952754
    Abstract: The present invention provides a drill guide for orthopedic surgery. The drill guide is configured to facilitate drilling of a bone tunnel with a correct and repeatable placement. The drill guide is designed for drilling of the femoral bone during knee surgery. More particularly, in certain embodiments the drill guide is designed for ACL repair and replacement surgery. In a preferred embodiment of the present invention, the guide has 5 members: a center rail, a side rail, an anteromedial slider, a femoral slider, and a center pin.
