Publication number: 20190083080Abstract: 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.Type: ApplicationFiled: November 15, 2018Publication date: March 21, 2019Inventors: Darryl D. D'Lima, Clifford W. Colwell, JR., David G. Matsuura, Philip J. Simpson

Patent number: 9051549Abstract: 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.Type: GrantFiled: February 22, 2012Date of Patent: June 9, 2015Assignee: Scripps HealthInventors: Shawn Patrick Grogan, Darryl David D'Lima, Clifford W.
