Publication number: 20190142596Abstract: A femoral prosthetic component includes a patellar guide portion, a pair of condyles projecting from the guide portion and forming an intercondylar notch therebetween, a bearing surface, and an interface surface configured to face a resected surface of a femur. The interface surface comprises an anterior face and a posterior face, and is substantially contoured between the anterior and posterior face to match a contoured surface of the femur. The substantially contoured interface surface may include at least one planar surface portion to about a flat cut portion in the surface of the femur. This planar surface portion may be a distal flat at a distal face of the interface surface. The contoured interface surface may alternatively include a plurality of planar surface portions. The femoral prosthetic component is configured such that preparation of the bone to match the interface surface results in minimal resection of the distal femur.Type: ApplicationFiled: January 16, 2019Publication date: May 16, 2019Inventors: Mark Ellsworth Nadzadi, Jason Karl Otto, Amit Mistry

Publication number: 20190029764Abstract: A robotic system for preparing a bone to repair a bone fracture, includes a controllable guide structure configured to guide preparation of at least one bone piece during execution of a surgical plan and a control system configured to define the surgical plan. Defining the surgical plan includes determining a desired relationship between at least a first bone piece and a second bone piece that are separated by the bone fracture and planning preparation of the first bone piece to include a prepared anatomical structure configured to align the first bone piece with the second bone piece such that when aligned, the first bone piece and the second bone piece will achieve the desired relationship. The control system is further configured to control the controllable guide structure according to the surgical plan.Type: ApplicationFiled: October 1, 2018Publication date: January 31, 2019Applicant: MAKO Surgical Corp.Inventors: Scott David Nortman, Amit Mistry, Jason K. Otto, Robert Van Vorhis, Mark Ellsworth Nadzadi, Miranda Jamieson

Publication number: 20180353298Abstract: Described herein is a bone implant including at least one bone-engaging surface designed to mate with an implant-engaging surface of a bone. In the preferred embodiment, the bone-engaging surface of the implant includes a wave pattern comprising at least one peak extending in a proximal direction or at least one valley extending in a distal direction. The implant-engaging surface of the bone also includes a matching wave pattern having at least one peak and valley. Upon mating the engaging surfaces, a bone-implant interface may be created wherein the peaks and valleys of the wave patterns are aligned. As a result, there is good surface contact area at the bone-implant interface which helps prevent loosening or rotating of the implant.Type: ApplicationFiled: June 8, 2018Publication date: December 13, 2018Inventors: Amit Mistry, Gokce Yildirim

Patent number: 10085804Abstract: A robotic system for preparing a bone to receive a prosthetic device. The robotic system includes a controllable guide structure configured to guide cutting of the bone into a shape for receiving the prosthetic device, and a computer readable medium for storing data representative of the prosthetic device. The prosthetic device includes a body portion having an implantation surface configured to face the bone upon implantation and at least one feature that provides a constraint structure that will constrain the prosthetic device in the bone. The robotic system includes a control system for controlling the guide structure, and is configured to define at least one bone-cutting pattern for (i) removing a first portion of bone in a first area sufficient to seat the body portion and (ii) at least one of removing and maintaining a second portion of bone in a second area configured to interact with the constraint structure.Type: GrantFiled: March 7, 2014Date of Patent: October 2, 2018Assignee: MAKO Surgical Corp.Inventors: Scott David Nortman, Amit Mistry, Jason K.

Publication number: 20180036129Abstract: An implant includes a base, a flange, and ridge. The flange extends from the base. The ridge extends from the flange. A hole extends through the flange and the ridge. A system with the implant includes a fastener extending through the ridge of the implant. The implant is placed into bone by securing a base of the implant to a main complementary contact surface of bone and by securing a ridge extending outwardly from a flange of the implant to a secondary complementary contact surface of bone spaced from the main complementary contact surface.Type: ApplicationFiled: July 31, 2017Publication date: February 8, 2018Inventor: Amit Mistry

Publication number: 20170333051Abstract: A method of preparing a tibia to receive a tibial implant component includes performing a first set of cuts to prepare a floor interface surface on the tibia, wherein the floor interface surface includes a portion on each side of a tibial eminence extending above the floor interface surface on the tibia. The method further includes performing a second set of cuts to prepare a tibial eminence wall interface surface, wherein the wall interface surface extends substantially perpendicular to the floor interface surface between the floor interface surface and a top surface of the tibial eminence. The method further includes performing a third set of cuts to prepare a radiused intersection between the floor interface surface and the wall interface surface. The sets of cuts are performed subject to a cutting restraint guide. At least one set of cuts may be performed using a rotary cutter.Type: ApplicationFiled: August 4, 2017Publication date: November 23, 2017Applicant: MAKO Surgical Corp.Inventors: Mark Nadzadi, Ali Abbasi, Amit Mistry, Jason Otto
