The body has a) opposing superior and inferior surfaces with or without corrugations, b) recesses formed in the opposing superior and inferior surfaces within a peripheral boundary of the body, and a recess-fill material (which preferably promotes osseointegration) disposed in the recesses.

A surgical implant and a surgical kit. The surgical implant has a body portion comprising a first hole formed in an exterior surface of the body portion, a second hole adjacent the first hole, and at least one through-hole within the body portion and extending entirely thought a depth of the body portion extending entirely thought a depth of the body portion. The implant has a central opening abutting the body portion and extending through the body portion. The first hole has a first sidewall and a first cavity in the body portion, the second hole has a second sidewall and a second cavity in the body portion, and the first cavity and the second cavity have an interconnected opening there between. The surgical kit includes the surgical implant and an intervertebral insertion device

A system and method for embedded electronics within a medical implant comprising: an implant body; a circuitry surface, containing at least one electronic component, wherein the circuitry surface is at least partially embedded within a defined cavity of the implant along at least one path; sheathing, comprising a protective structure, wherein the at least partially embedded portion of the circuitry surface is enclosed within the sheathing; electronic components connected to, or directly on, the circuitry surface, comprising a set of electrodes and an antenna; and wiring, connecting the circuitry surface and electronic components. The system and method may further include a casing, wherein the casing is a sealed structure directly connected to the implant body including a printed a circuit board (PCB) contained within the casing itself.

An implant-trialing instrument for objectively determining a recommended implant size based at least in part on results of inserting a pressure sensitive trial implant into the intervertebral space. The trial implant instrument can include a handle coupled to a pressure sensitive trial. The handle can include an elongate shaft. The pressure sensitive trial implant can be disposed on a distal end of the elongate shaft and include a superior end plate surface configured to engage a first end plate of a first vertebral body and an inferior end plate configured to engage a second end plate of a second vertebral body. The pressure sensitive trial implant also includes a pressure sensitive film disposed on at least one of the superior end plate and the inferior end plate.

Systems and methods for performing surgery based on an analysis of images captured in at least two different planes are disclosed. According to some embodiments, a first X-ray image of a spine in a first plane and a second X-ray image of the spine in a second plane are obtained, and a curve is drawn on the first and second X-ray images so that the curve tracks the vertebral bodies of the spine. The coordinates of the curve in the first and second X-ray images are determined by performing image processing to detect the curve in the X-ray images. A three-dimensional model of the spine is constructed based on the coordinates. The model is analyzed based on medical data relating to the spine and models of other spines to determine parameters of a spinal device. The spinal device is constructed and deployed in the spine based on the parameters.

The present invention provides an expandable fusion device capable of being installed inside an intervertebral disc space to maintain normal disc spacing and restore spinal stability, thereby facilitating an intervertebral fusion. In one embodiment, the fusion device includes a central ramp, a first endplate, and a second endplate, the central ramp capable of being moved in a first direction to move the first and second endplates outwardly and into an expanded configuration. The fusion device is capable of being deployed down an endoscopic tube.

A method for treating a spine includes the steps of: creating a surgical pathway in a body along a first surgical approach to a surgical site including vertebral tissue; creating a surgical pathway in the body along a second surgical approach to the surgical site including the vertebral tissue; disposing a fulcrum with an intervertebral disc space of the vertebral tissue via the first surgical approach; and manipulating the vertebral tissue via the second surgical approach. Spinal implants, surgical instruments and systems are disclosed.

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.

An implantable prosthesis that includes a biased coiling member and a conforming coiling member. The biased coiling member may be biased to curve from a substantially linear configuration to a nonlinear configuration. The conforming coiling member may be engaged with and curved by the biased coiling member from the substantially linear configuration to the nonlinear configuration. The biased coiling member may define a longitudinal axis when in the substantially linear configuration. The biased coiling member and the conforming coiling member may move relative to each other along the longitudinal axis. The prosthesis may be implanted in a surgical procedure that minimizes incision sizes and may be considered less invasive than typical implant procedures, especially spinal implant procedures.
