A medical implant for a human shoulder joint includes a first magnetic implant fixed to the non-articular surface of the greater tuberosity of the human shoulder joint, and a second magnetic implant fixed to an outer surface and underside of the acromion of the human shoulder joint. At least one of the first and second magnetic implants generates a magnetic field that urges the first and second magnetic implants away from each other and thereby distracts the humeral head of the human shoulder joint from the acromion.

The present invention provides for an improved spinal implant which is useful in bone fixation surgeries. The spinal implant as described herein provides a surgeon with a device that can easily and safely be inserted into the space previously occupied by the spinal disc. The spinal implant contains one or more magnets positioned on or within the device to self-align with one or more additional spinal implants inserted therein for the purpose of preventing misalignment of a plurality of implant devices during surgical procedures and preventing implant expulsion.

A method for performing a surgical procedure on a patient using a robotic system and a navigation system. The robotic system includes a cutting tool. The navigation system has at least one locating device to track a portion of the patient during the surgical procedure. The navigation system provides information as to a position of the portion of the patient. An optical cutting guide is projected onto the portion of the patient to enable cutting of the portion of the patient with the cutting tool of the robotic system while the optical cutting guide is projected onto the portion of the patient.

The application is directed to devices and methods where one or more magnetic or magnetizable implants provides therapeutic benefits to a patient. The implant may be useful for expanding the range of motion of joints or dynamically providing different responses to changing conditions in the body where the implant is placed. An electromagnet is placed on or in a bone on one side of a joint, and another electromagnet or magnetically active material is placed on or in a bone on the opposing side of the joint. The electromagnet may be continuously energized to relieve pressure in the joint space, or may be energized in response to forces applied to the joint.

An electronically assisted artificial vertebral disc having an upper disc plate and a lower disc plate is disclosed. An actuator imparts movement to at least one of the upper and lower disc plates. A control device controls the actuator and the amount of movement between the disc plates. The actuator includes a plurality of either linear actuators or rotary actuators that are driven by electric motors in response to the control device. The control device includes at least a first sensor for detecting the position of the actuator and at least a second sensor for detecting the spatial orientation of at least one of the upper and lower disc plates. The control device also preferably includes a microprocessor that calculates the desired positions of the upper and lower disc plates and provides a control signal to the actuator to drive the upper and lower disc plates to their desired positions.

A spinal implant which is configured to be deployed between adjacent vertebral bodies. The implant has at least one extendable support element with a retracted configuration to facilitate deployment of the implant and an extended configuration so as to expand the implant and effectively distract the disc space, stabilize the motion segments and eliminate pathologic spine motion. The implant has a minimal dimension in its unexpanded state that is smaller than the dimensions of the neuroforamen through which it typically passes to be deployed within the intervertebral space. The implant is provided with a locking system having a plurality of linked locking elements that work in unison to lock the implant in an extended configuration. Bone engaging anchors also may be provided to ensure secure positioning.

In some examples, a prosthesis system comprises a socket housing comprising a socket configured to receive a residual limb of a wearer. The socket housing further comprising a pylon extending distally of the socket. The socket housing further comprising a first interlock structure at a distal end of the pylon where the first interlock structure comprises a first one or more programmed magnets. The prosthesis system further comprising an extremity unit configured to be attached to and removed from the pylon where the extremity unit comprises a second interlock structure comprising a second one or more programmed magnets. The pylon and the extremity unit are configured such that, when the extremity unit is attached to the pylon, the first and second one or more programmed magnets are positioned and oriented to magnetically attract each other and secure the extremity unit to the pylon.

Disclosed are methods, systems, and devices for the endovascular repair of cardiac valves, particularly the atrioventricular valves which inhibit back flow of blood from a heart ventricle during contraction. The procedures described herein can be performed with interventional tools, guides and supporting catheters and other equipment introduced to the heart chambers from the patient's arterial or venous vasculature remote from the heart. The interventional tools and other equipment may be introduced percutaneously or may be introduced via a surgical cut down, and then advanced from the remote access site through the vasculature until they reach the heart.

Exemplary assemblies, apparatuses, systems, methods, and kits are provided herein related to modular tibial inserts. One such assembly can comprise a modular tibial insert assembly having: a modular medial insert component, the modular medial insert component having a medial component proximal side proximally disposed from a medial component distal base side, wherein a medial component body extends between the medial component proximal side and the medial component distal base side; a modular lateral insert component, the modular lateral insert component having a lateral component proximal side proximally disposed from a lateral component distal base side, wherein a lateral component body extends between the lateral component proximal side and the lateral component distal base side; wherein the modular tibial insert assembly has an assembled configuration and a disassembled configuration, and wherein the modular medial insert component is configured to fixedly engage the modular lateral insert component in the assembled configuration.

A method for implantating a medical device in a hip joint of a patient is provided. The medical device is adapted to be fixated to the pelvic bone of the patient, and comprises an inner and an outer surface, a contacting portion of the inner surface is spherical and adapted to face the center of the hip joint when said medical device is implanted, and said medical device is adapted to receive a caput femur or a prosthetic caput femur having a spherical portion. The medical device comprises at least one extending portion adapted to clasp the caput femur, or prosthetic caput femur, for restraining said caput femur, or prosthetic caput femur in said medical device. The medical device is adapted to release the caput femur or prosthetic caput femur from the medical device when a predetermined strain is placed on the medical device. The ability of the medical device to release the caput femur or prosthetic caput femur from the medical device when a predetermined strain is placed on the medical device reduces the risk that the prosthesis is loosened by an abnormal strain being placed on the hip joint from e.g. the patient falling or making a rapid movement of the hip.
