A protective cover prevents undesired leakage of materials out of a spinal implant. In one embodiment, the implant is a lateral interbody fusion implant that accommodates biologically active material to promote bone ingrowth. The protective cover prevents unintended migration of the biologically active material out of the implant and into surrounding tissue.

A bone void plug includes a plug body that extends along a longitudinal axis between a proximal face and a distal opening and a recessed opening that extends from the distal opening toward the proximal face. The recessed opening is configured to receive a bone void filler.

A system for assisting in a surgical process, comprising: (a) a surgical device taken from a group consisting of a surgical tool and a surgical implant; (b) a positional sensor carried by the surgical device, the positional sensor including a wireless transmitter and associated circuitry for transmitting sensor data from the transmitter; and (c) a computer system including a wireless receiver and signal conditioning circuitry and hardware for converting sensor data received by the wireless receiver into at least one of (i) audio feedback of positional information for the surgical device and (ii) visual feedback of positional information for the surgical device.

Systems for minimally invasive disc augmentation include an anulus augmentation component and a nucleus augmentation component. Both are suited for minimally invasive deployment. The nucleus augmentation component restores disc height and/or replaces missing nucleus pulposus. The anulus augmentation component shields weakened regions of the anulus fibrosis and/or resists escape of natural nucleus pulposus and/or the augmentation component. Methods and deployment devices are also disclosed. Method of supporting and augmenting a nucleus pulposus by inserting a flexible biocompatible material into the disc space using an anchoring means are also provided.

An augment device for a joint endoprosthesis, the device comprising: a sleeve having a top and a bottom, a distance between said top and said bottom defining an entire height of said sleeve, wherein the sleeve surrounds a channel extending through the sleeve from the top to the bottom of the sleeve wherein the channel is configured to receive a stem of the joint endoprosthesis; the sleeve comprising an inner face and an outer face, the inner face defining the channel, and a distance between the inner face and the outer face defining a thickness; the sleeve further comprising a porous material configured for ingrowth of bony material.

A system for assisting in a surgical process, comprising: (a) a surgical device taken from a group consisting of a surgical tool and a surgical implant; (b) a positional sensor carried by the surgical device, the positional sensor including a wireless transmitter and associated circuitry for transmitting sensor data from the transmitter; and (c) a computer system including a wireless receiver and signal conditioning circuitry and hardware for converting sensor data received by the wireless receiver into at least one of (i) audio feedback of positional information for the surgical device and (ii) visual feedback of positional information for the surgical device.

Integratable treatment devices, assemblies including a treatment device, at least one anchor, and a tether coupled thereto, and various methods and devices for inserting such devices and assemblies are disclosed herein. The treatment devices can be made of an integratable material that is not fully bioresorbable but promotes native tissue growth in and around the material. Certain methods involve first inserting at least one anchor and then advancing a treatment device via a tether coupled to the at least one anchor. Further various insertion devices that can be used to implant any of the treatment devices herein using any of the methods herein are disclosed.
