  • Patent number: 11950784
    Abstract: Described here are devices for closing one or more tissues, and handles for controlling these devices. Generally, the devices described here comprise a snare loop assembly, wherein the snare loop assembly comprises a snare and a suture loop, and a handle for controlling the snare loop assembly. In some variations the snare loop assembly may comprise a retention member that may releasably connect the suture loop to the snare. In other variations the devices comprise one or more force-reducing suture locks to help prevent the suture loop from inadvertently disengaging from the snare loop assembly. In still other variations, the excess-suture management features. The handles described here may be configured to remove excess suture from a suture loop, and may also be configured to release the suture loop from the snare loop assembly.

  • Patent number: 11793543
    Abstract: An automatic insertion device and method of using the same is provided. A vibrator and an extender are connected to a penetrating member and are both in electrical communication with a controller. A detector identifies a subcutaneous target for insertion and the insertion angle, distance and trajectory for the penetrating member are calculated. The vibrator provides vibrations to the penetrating member and the extender advances the penetrating member for insertion. The vibrator and extender are in electrical communication with one another during the insertion process and adjustments to the insertion speed are made based on feedback of vibrational load encountered by the vibrator during insertion, and adjustments to the vibrations are made based on feedback of insertion load encountered by the extender during insertion. Iterative samples are taken to constantly adjust the operation of one motor based on the operations and feedback from the other motor.

  • Publication number: 20230277295
    Abstract: A device for modifying blood flow through a target artery of a patient is described. A method for treating obesity in a patient includes positioning the device in a first artery to decrease blood flow through a second artery causing hypoperfusion to a gastrointestinal organ serviced by the second artery, and interfering with gastrointestinal function to induce weight loss. A system for placement of a blood flow modification device within a first artery to gradually reduce blood flow to a second target artery while maintaining blood flow to the first artery is also provided. The device may be modifiable after treatment to restore or increase blood flow to the artery.

  • Publication number: 20230218348
    Abstract: A surgical instrument assembly configured to display a representation of the surgical instrument relative to a trajectory (e.g., a desired trajectory for drilling into an implant) based image data from an image sensor (e.g., a camera). For example, the surgical instrument assembly may be configured to determine a desired trajectory (e.g., a central axis of a distal hole of an intramedullary nail) based on X-ray image data representing at least one fiducial marker (e.g., an array of ArUco markers) and representing an anatomical structure and/or an implant. The surgical instrument assembly may in real time display a representation of the orientation and/or position of the surgical instrument (e.g., the orientation and position of a drill bit of the surgical instrument) in relation to the desired trajectory based on image sensor data that is generated based on an orientation of the at least one fiducial marker detected by an image sensor.

  • Publication number: 20210401579
    Abstract: Devices and methods for providing localized pressure to a region of a patient's heart to improve heart functioning. The devices include a cardiac jacket made of a flexible biocompatible material and at least one inflatable bladder disposed on an interior surface of the jacket. Inflation of the bladder causes the bladder to expand to exert localized pressure against a region of the heart. In some cases, a phase-change material is filled into the bladder as a liquid and the material solidifies at body temperature. In some cases, a positioning tool is used prior to the implantation of the jacket in order to determine effective positions for the inflatable bladder(s) to be located on the heart to improve heart functioning.
