Abstract: An implant may include a curved implant body and a flange extending from the implant body, the flange being thinner than the implant body, the implant body and the flange having a first exterior surface and a second exterior surface opposite the first surface in which the implant body and the flange formed by at least partially fused particles. The particles at the first surface define a first average pore size and the particles at the second surface define a second average pore size; with the first average pore size being greater than the second average pore size. The first surface may be a tissue ingrowth surface and the second surface may be a tissue ingrowth barrier.

Abstract: An implant that can function as a tissue suspension implant. Embodiments find particular use in connection with eyebrow or forehead lifts, which require raising of soft tissue and skin of the forehead and brow.

Abstract: In one aspect, the disclosure relates to a continuous process for treating acid mine drainage while simultaneously recovering a high-grade rare earth preconcentrate suitable for extraction of commercially valuable rare earth oxides. In a further aspect, the preconcentrate is from about 0.1% to 5% rare earth elements on a dry weight basis. In another aspect, the disclosure relates to a method for processing the preconcentrate to generate a pregnant leach solution that does not form gels or emulsions and is suitable for processing via solvent extraction. In another aspect, the disclosure relates to a system and plant for carrying out the disclosed process. In still another aspect, the disclosure relates to a composition containing rare earth elements produced by the process disclosed herein. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present disclosure.

Abstract: An orbital floor template packaged along with an implant. The two components are provided together in a single sterile package. This allows the surgeon to pull a single package and have the implant and a pre-sized template available during surgery. This avoids the need to pull a second implant from the operating room materials shelf for sizing purposes only. The template is used during surgery and prevents the need to use a separate, new, sterile, separately-packaged actual implant for sizing purposes.

Abstract: Embodiments of the present disclosure relate generally to an orbital floor implant (10). One embodiment provides an implant with a first surface that is a fully porous, bone-side layer (16) and a second surface that is a non-porous, orbital content-side layer (18). The implant material itself may be polymeric material throughout, without the need for an embedded mesh or other support matrix. The implant is provided in a pre-shaped configuration and is of a material that allows it to be bent for shaping purposes. An extending tab (12) with eyelet portion/opening (14) can enhance securement options to a patient's bone.

Abstract: Differences in x-ray absorption coefficients and ash content are used to process coal waste and concentrate rare earth elements (REE) found in coal seams. A method for processing the coal waste includes receiving, by a detector, at least one collimated x-ray beam from an x-ray source that has been passed through a sample of coal waste; determining measurements of at least one x-ray absorption characteristic of the sample based on the received at least one collimated x-ray beam; and identifying a first region in the sample having a concentration of rare earth elements based on the measured x-ray absorption characteristic.

Abstract: Embodiments of the invention described herein thus provide implants and methods for manufacturing an implant having an outer layer that is porous. The porous outer layer can help encourage tissue ingrowth into the implant. The porous outer layer may be positioned around a core structure this is solid or that has a hollow interior. The core structure may be spherical or any other appropriate shape for a medical implant.

Abstract: Embodiments of the invention described herein thus provide systems and methods for providing improved surgical implants. Embodiments of the implants may include a thin porous sheet formed on a mandrel. The porous sheet that is formed has an interconnected pore structure that may be compressed by a heat compression mold without losing porosity. Additional membrane materials or other layer materials may be applied to one of the face surfaces of the porous sheet or to one of the edges of the porous sheet. For example, a solid membrane surface may be compressed, bonded, welded, or secured a surface face or an edge of the porous sheet. The solid membrane may be compressed or laminated to the upper surface, lower surface, or both. The solid membrane may be welded to at least one edge of the porous sheet (by, for example, being butt welded, thermally bonded, or heat compressed to the at least one edge).

Abstract: Embodiments relate generally to channel implants used for surgical reconstruction and/or repair. Certain embodiments of the channel implants are designed for craniofacial surgery, reconstruction, and/or augmentation. More specifically, some embodiments find particular use in orbital reconstructive surgery, such as repair of the orbital floor or supraorbital ridge (brow ridge). Embodiments also relate to methods for using and for manufacturing the channel implants disclosed.
