The present invention includes a fluid interface system for use in medical implants. The fluid interface system of the present invention can include one or more fluid interface channels disposed within an implant. The fluid interface systems can optionally include fluid redirection channels, fluid interface ports and a corresponding instrument to transfer fluid in or out of the fluid interface ports.

The present disclosure relates to the technical field of medical supplies, in particular to a fusion cage. The fusion cage comprises a main body, which is a flat-shaped porous structural body and composed of a plurality of structural units. The fusion cage provided by the present disclosure is the flat-shaped porous structural body composed of the plurality of structural units, the porosity of the whole structure of the fusion cage is controlled by using the parametrization design, so the elastic modulus of a fusion body is effectively reduced, and then each structural unit comprises the basal body and the plurality of extension portions extending from the surface of the basal body, the surfaces of the basal body and/or the extension portions are composed of the plurality of curved surfaces through smooth connection, and such design effectively reduces the problem of stress concentration, and improving the postoperative recovery effect of patients.

An implant for therapeutically separating bones of a joint has two endplates each having an opening through the endplate, and at least one ramped surface on a side opposite a bone engaging side. A frame is slideably connected to the endplates to enable the endplates to move relative to each other at an angle with respect to the longitudinal axis of the implant, in sliding connection with the frame. An actuator screw is rotatably connected to the frame. A carriage forms an open area aligned with the openings in the endplates. The openings in the endplates pass through the carriage to form an unimpeded passage from bone to bone of the joint. The carriage has ramps which mate with the ramped surfaces of the endplates, wherein when the carriage is moved by rotation of the actuator screw, the endplates move closer or farther apart.

A vertebral body system and method having a polyaxial fastener receiving member, adjustable width plates and a pedicle screw having a pedicle threaded portion and a threaded portion for fastening to the vertebral body.

Intervertebral endoprosthesis discs suitable for surgical implantation between two vertebrae having and methods thereof. The prosthetic disc may have an endoprosthesis body including an anterior region and a posterior region designed to be positioned between a first vertebra and a second vertebra with a first and second movable insert positioned rotatably in anterior cavities and is rotatable to adjust the fasteners.

A method of manufacturing an orthopedic implant is provided. The method includes creating a 3D model of an orthopedic implant having a solid portion and a porous portion and selectively adjusting a physical property of at least one of porosity of the porous portion, lattice thickness of the porous portion, beam profile of the porous portion, and topography of the 3D model. The entire implant is then additively manufactured based on the 3D model.
