An implant is produced by fabricating first and second layers. The first layer of repeated and truncated building units is fused together to define pores. The second layer of repeated and truncated building units are fused together to define pores and fused onto the first layer of truncated building units. The first and the second layers form at least part of a porous portion of the implant. The formed porous portion is attached onto a base portion of an implant. The truncated building units of each of the first and the second layers are in the form of spatially overlapping three-dimensional shapes.

Apparatus, method and system for providing customizable bone implants

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.

METHOD OF MANUFACTURING MEDICAL IMPLANT

A method of manufacturing an implant is disclosed. The method includes preparing a wax template assembly based upon anatomical characteristics of an implantation site. Post formation of the template assembly, a lamination layer is provided over the template assembly resulting in a laminated template assembly. The lamination layer is composed of at least one polymer dissolved in one or more solvents. One or more coating layers of a pre-defined coating material are provided over the laminated template assembly to prepare a mold. The mold may then be sand-rained to form a sand coated mold. The sand coated mold may be de-waxed and baked for melting out the template assembly to form a de-waxed mold. A casting material is then poured over the de-waxed mold to form a casted mold which is cooled and solidified to form a casted implant which is further heat treated and finished to form the implant.

IMPLANTABLE MEDICAL DEVICE WITH VARIED COMPOSITION AND POROSITY, AND METHOD FOR FORMING SAME

A method for forming a thermoplastic body having regions with varied material composition and/or porosity. Powder blends comprising a thermoplastic polymer, a sacrificial porogen and an inorganic reinforcement or filler are molded to form complementary parts with closely toleranced mating surfaces. The parts are formed discretely, assembled and compression molded to provide a unitary article that is free from discernible boundaries between the assembled parts. Each part in the assembly has differences in composition and/or porosity, and the assembly has accurate physical features throughout the sections of the formed article, without distortion and nonuniformities caused by variable compaction and densification rates in methods that involve compression molding powder blends in a single step.
