The present invention includes a method for generating a three-dimensional model of a bone and generating a cut plan for excavating a portion of the bone according to the cut plan to allow the insertion of a custom implant. In a particular arrangement, the method also includes excavating the bone with an autonomous extremity excavator utilizing the cut plan generated by a processor. In a further arrangement, the method includes generating a digital model of a custom implant and generating, using the digital model, a physical model sharing the same dimensions as the digital module using manufacturing device.

The invention relates to a bone implant (1) for correcting an incorrect position of a bone, the bone implant (1) having a first portion (2) for attachment to a first bone portion (3) and a second portion (4) for attachment to a second bone portion (5), the bone implant (1) being prepared so that, when fixed to the bone, it orients the first bone portion (3) and the second bone portion (5) with respect to one another and keeps said portions at a distance from one another, the bone implant (1) having such a geometry and being adapted so as to force a predetermined orientation of the second bone portion (5) relative to the first bone portion (3). The invention also relates to a method for producing such a bone implant (1).

Expandable fusion devices capable of being inserted between adjacent vertebrae to facilitate the fusion process. The expandable fusion device may include first and second endplates, a translation member configured to expand an anterior side and/or posterior side of the device, a plurality of joists configured to connect the first and second endplates to the translation member, and first and second actuation members disposed internally to the device such that openings on a back side of the device can be used to expand or compress the anterior side, the posterior side, or both and such openings may also be used to introduce graft material into the device.

A system and method for improving upon an ability of a surgeon to repair traumatic bone injury using new materials, components, and structures. A structure may be used as an implant or a component of an external fixator for a fractured long bone with that structure having anisotropic and viscoelastic properties, such as through additive manufacturing techniques.

A stent for insertion into a vessel of a patient includes an inner tube comprising a positive Poisson's ratio (PPR) material and defining a lumen extending along a longitudinal axis of the stent; and an outer tube comprising a negative Poisson's ratio (NPR) foam material and disposed around an entirety of the inner tube, the outer tube extending along the longitudinal axis of the stent. The stent is configured to exhibit an auxetic behavior in response to a deformation of the stent. An outer surface of the second portion is configured to apply a pressure to an inner surface of the vessel when the stent is implanted into the vessel and the deformation is removed.

Methods of bioprinting a bio-ink construct on an internal tissue defect or a chondral defect during a minimally invasive surgery on an individual in need thereof are provided, comprising: visualizing the defect; positioning a bioprinter comprising a printhead within proximity of or in contact with the defect; and ejecting a bio-ink from the printhead onto the defect to form a bio-ink layer, thereby generating a bio-ink construct. Further provided are systems for bioprinting a bio-ink construct on an internal tissue defect during a minimally invasive surgery on an individual in need thereof, comprising a control system, an endoscope, and a bioprinter comprising a printhead.

The biocompatible lattice structures and implants disclosed herein have an increased or optimized lucency, even when constructed from a metallic material. The lattice structures can also provide an increased or optimized lucency in a material that is not generally considered to be radiolucent. Lucency can include disparity, maximum variation in lucency properties across a structure, or dispersion, minimum variation in lucency properties across a structure. The implants and lattice structures disclosed herein may be optimized for disparity or dispersion in any desired direction. A desired direction with respect to lucency can include the anticipated x-ray viewing direction of an implant in the expected implantation orientation.

The invention relates to a vertebral prosthesis with outstanding functionality, adaptability, and safety with respect to its predecessors. It is conceived and designed to provide a better service and serve as an axis so that spinal operations, as well as other diseases can be better addressed. It seeks, above all, to adapt to the nature of human biology and resembles that nature as much as possible, based on an internal suspension system which allows greater mobility and better weight distribution, imitating the natural deformation of the bone.

In one embodiment, an intervertebral implant includes a body and a locking element. The body includes a leading surface and a trailing surface opposite the leading surface. The body also includes first and second bone fastener passageways through the implant body and a cavity in between the first and second passageways. The cavity includes a trailing wall that separates the cavity from the trailing surface. The locking element is disposed in the cavity such that part of the locking element is visible through an access opening in the trailing wall so that the locking element may be rotated from outside of the implant. In a first rotational position, a first part of the locking element is located within one of the first and second passageways and in a second rotational position, the first part of the locking element is inside the body covered by the trailing wall.

This disclosure describes spinal implants with anchoring elements including an aperture for delivery of injectable materials. In one aspect, a spinal implant includes a body defining one or more injection ports and one or more channels, the one or more injection ports configured to receive flowable material and to provide the flowable material to the one or more channels; and one or more anchoring elements protruding from a surface of the body, the one or more anchoring elements each defining an aperture coupled to the one or more channels and configured to receive the flowable material from the one or more channels and to provide/output the flowable material from the aperture.
