Patent number: 11446163Abstract: An endplate plunger for implanting a growth-promoting tether between opposed adjacent vertebrae. The endplate plunger includes resilient arm assemblies that store potential energy when the endplate plunger is in a retracted configuration. In transitioning from the retracted configuration to a deployed configuration, the potential energy is released in a burst of kinetic energy, causing tip portions at the distal ends of the resilient arm assemblies to be thrust into the adjacent vertebrae. In some embodiments, each tip portion forms a cleft in the respective vertebral endplate and deposits the tether therein. The tether is thereby anchored directly in the clefts, without need for separately formed anchors. In some embodiments, devices and methods are disclosed to route the tether through an implanted spinal implant.Type: GrantFiled: April 3, 2020Date of Patent: September 20, 2022Assignee: Advanced Research Systems, LLCInventors: Hamid R. Abbasi, Stuart J. Olstad

Patent number: 11432898Abstract: There is provided a tracing platform configured to rigidly attach to an anatomy of a patient that has at least one surface configured to provide a defined path (represented by path definition data) for tracing by a surgical instrument. An intra-operative computing unit receives pose data for the instrument when tracing the path and calculates a location of the defined path using the pose data and the path definition data. A change in location may be determined from pose data of different traces. Tracing the defined path generates a plurality of pose data which may increase accuracy of the location calculations. Redundant trace data may be received to eliminate bias. A geometric feature (e.g. V-groove), shape and/or magnetic properties of the platform may assist with tracing. The platform may rigidly attach to a bone using at least one of spikes, a bone screw, a cerclage wire, and a bone clamp.Type: GrantFiled: March 13, 2018Date of Patent: September 6, 2022Assignee: INTELLIJOINT SURGICAL INC.Inventors: Joseph Arthur Schipper, Andre Novomir Hladio, Kevin Morency
