Patent number: 12201379Abstract: 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.Type: GrantFiled: February 24, 2022Date of Patent: January 21, 2025Assignee: DePuy Synthes Products, Inc.Inventors: Megan Greenwood, William E.

Publication number: 20240315729Abstract: 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.

Patent number: 12023249Abstract: 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.Type: GrantFiled: April 25, 2019Date of Patent: July 2, 2024Assignee: DiaxaMed, LLCInventors: Eugene Andrew Grossi, William E.
