Publication number: 20240058039Abstract: A modular screw assembly for use in stabilizing a spinal column. The assembly has a fastener which couples to a screw head of a bone anchor, a screw head coupler, a retaining ring, and a friction ring. The fastener houses the screw head coupler, the retaining ring, and the friction ring. Translation of the fastener by the screw head results in the retaining ring elastically deforming and then snapping around the screw head.Type: ApplicationFiled: June 6, 2023Publication date: February 22, 2024Inventors: John Franklin Cummins, John Lawrence Walker

Publication number: 20240033090Abstract: A plate and cage assembly for stabilization of vertebral bodies. The assembly includes at least one fixation member, a cage having a proximal wall, a superior surface and an inferior surface (the superior surface and the inferior surface for engaging adjacent vertebrae), and a plate coupled to the cage and having at least one hole traversing the plate at an angle for insertion of the at least one fixation member into one of the vertebral bodies. The proximal wall of the cage has a blind hole, and the plate has a threaded screw hole aligned with the blind hole in the proximal wall of the cage.Type: ApplicationFiled: January 12, 2023Publication date: February 1, 2024Inventor: John Franklin Cummins

Publication number: 20240024007Abstract: A bone cement mixing and dispensing system and method for mixing and delivering bone cement therefrom. The system has a mixing container for holding a bone cement mixture, the mixing container extending along an axial length and having opposed first and second ends, the first end comprising a downstream opening for dispensing the bone cement downstream from the mixing container; a mixing element movably disposed within the mixing container; and a plunger comprising a piston movably disposed within the mixing container. In this system. with a first coupling, the mixing element moves by assistance of a motor along the axial length of the mixing container without translation of the plunger to mix the bone cement. In this system. with a second coupling, the mixing element and plunger are driven together along the axial length of the mixing container.Type: ApplicationFiled: July 24, 2023Publication date: January 25, 2024Inventors: Colby Williams, John Franklin Cummins, John Lawrence Walker, Brad Risher, Christopher Strahm, Talya Mathein

Patent number: 11857436Abstract: A surgical implant and a surgical kit. The surgical implant has a body having at least one interior surface, the body forming a peripheral support for the implant. The surgical implant has a porous insert comprised of a porous material, having at least one axially-extending hole, and attached to the body along the at least one interior surface such that the porous material extends across a height of the body. The porous insert has a locking mechanism formed in the porous insert or extending from the porous insert, the locking mechanism minimizing movement of the porous insert from within the body. The surgical kit includes the surgical implant and an intervertebral insertion device.Type: GrantFiled: July 27, 2020Date of Patent: January 2, 2024Assignee: ZAVATION MEDICAL PRODUCTS, LLCInventors: Katie Lynn Motley, John Franklin Cummins, Joseph Matthew Jones, John Lawrence Walker, Colbert Yeates Williams

Patent number: 10874443Abstract: Internal fixation devices are provided that include a plate having a rotatable screw lock mounted in a recess of the plate. The screw lock has a lock head including a laterally extending flange that has an outer edge that is below the upper surface of the plate. In a locked position, a portion of the upper surface of the plate covers at least a part of the lock head to reduce the likelihood of the screw lock being pushed off the plate. Further, in a locked position, the laterally extending flange obstructs passage of a screw through a corresponding screw hole. Such obstruction hinders screw migration.Type: GrantFiled: March 20, 2018Date of Patent: December 29, 2020Assignee: Zavation Medical Products, LLCInventors: Jeffrey Johnson, John Lawrence Walker, John Franklin Cummins

Patent number: 10758365Abstract: A spinal implant for placement between first and second vertebrae includes a housing having first and second axial end surfaces and a bore extending along an axis through the housing and between the end surfaces. A first projection extends at least partially about the axis and including a channel. A lift is slidably received in the bore and includes threads along its length. A collar is threadably engaged with the lift and extends into the channel on the housing such that the projection prevents axial movement of the collar relative to the housing. Rotation of the collar about the axis causes the lift to move axially relative to the collar and the housing for adjusting the height of the implant.Type: GrantFiled: May 8, 2018Date of Patent: September 1, 2020Assignee: Zavation Medical Products, LLCInventor: John Franklin Cummins

Patent number: 10660677Abstract: An expandable bone plate assembly is provided having a top plate portion and a bottom plate portion. A back side of the top plate portion has a longitudinally extending blind slot. A transversely extending counterbore extends through front back sides of the top plate portion. A transversely extending bore extends through the front and back sides of the bottom plate portion. The bone plate assembly also includes a pin with a pin head and a pin shaft depending from the pin head. The pin shaft is disposed within the transversely extending bore of the bottom plate portion and has an outer diameter greater than the minor diameter of the transversely extending bore. The pin head is disposed against the longitudinally extending blind slot of the top plate portion.Type: GrantFiled: March 21, 2018Date of Patent: May 26, 2020Assignee: ZAVATION MEDICAL PRODUCTS, LLCInventors: John Franklin Cummins, John Lawrence Walker, Eric Graham

Patent number: 10383675Abstract: A surgical screw driving device for driving a screw into a surgical fixture. The device has a screwdriver having a proximal end, a distal end having a driver for engaging the screw, and an elongated shaft extending therebetween. The device has a screw retainer surrounding and extending along the elongated shaft. The screw retainer is configured to engage and hold a periphery of a screw head prior to the screw being driven into the surgical fixture. The screw retainer is configured to disengage from the periphery of the screw head as an axial end of the screw retainer contacts the surgical fixture and is further configured, upon disengagement and without necessity of outside assistance, to translate along the elongated shaft of the screwdriver away from the distal end and toward the proximal end.Type: GrantFiled: September 19, 2018Date of Patent: August 20, 2019Assignee: ZAVATION, LLCInventors: John Franklin Cummins, John Lawrence Walker, Joseph Matthew Jones
