  • Publication number: 20250120784
    Abstract: A joint replacement balancing system which provides real-time feedback to a surgeon during a joint replacement surgery to assist the surgeon to balance a joint replacement. The joint replacement balancing system includes a non-transitory processor-readable medium storing code representing instructions to cause a processor to receive a signal from a joint balancing apparatus, determine if the joint replacement is out of balance, determine a corrective course of action to bring the joint into balance and generate and display to the surgeon during the joint replacement surgery a recommended corrective course of action to complete the joint replacement surgery.

  • Publication number: 20190083080
    Abstract: A joint balancing insert with sensors and an actuated mechanism is disclosed. The joint balancing insert is used to balance a joint during arthroplasty surgery, as the sensors provide force, position and angular data relating to the movement of the joint, while the actuated mechanism allows for highly accurate and dynamic adjustments of the joint based on the data from the sensors. Various configurations of actuated mechanisms and sensors may be implemented in the insert to provide for manual or real time control of the insert, and customized interfaces are provided for visualized feedback of adjustments. Sensor data may also be collected and compared with expected or preferred data sets to provide adjustment recommendations and achieve better outcomes based on historical data.

  • Patent number: 9597158
    Abstract: There is disclosed a method of balancing a joint during a surgical procedure, to both maximize the range of motion of the joint and to reduce the likelihood of follow-up procedures. The method includes outputting a signal including a first data set associated with at least one of a force, a position, a displacement or a rotation associated with an apparatus disposed between a first bony structure and a second bony structure, the apparatus including a first portion configured to be coupled to the first bony structure, a second portion configured to be disposed between the first portion and the second bony structure, and a transducer and an actuator disposed between the first portion and the second portion.

  • Patent number: 9051549
    Abstract: Methods are provided for the three dimensional manipulation of cells, and for the formation of an organized engineered cell tissue. Also provided are the organized engineered cell tissues produced by the methods. In one method, a plurality of magnetically labeled cells are mixed with a cross-linkable hydrogel to form a cell-hydrogel mixture, the at least a portion of the plurality of magnetically labeled cells are manipulated with a magnetic field to arrange the magnetically labeled cells into a specific cellular arrangement, and the hydrogel is crosslinked to form the organized engineered cell tissue. The approach presented herein offers a means to circumvent the deficiencies in the field of regenerative medicine, and allows for the production of organized tissues in situ with specific cellular organizations that mimic the native tissue.
