LINERS FOR MEDICAL JOINT IMPLANTS WITH IMPROVED WEAR-RESISTANCE
A polymeric liner for a medical joint implant constructed to be positioned in between a head (or a top plate) and a stem (or a base plate) of the medical joint implant. The polymeric liner is composed of at least one component. The at least one component includes a polymeric matrix having a polymeric material having a volume concentration of between 95%-99.9% v/v (volume per volume); and at least one metal chalcogenides or dichalcogenides nanotube nanoparticle having a volume concentration of between 0.1%-5% v/v. The at least one metal chalcogenides or dichalcogenides nanoparticle is distributed within the polymeric matrix, and selected from the group consisting of: TiS2, TiSe2, TiTe2, WS2, WSe2, WTe2, MoS2, MoSe2, MoTe2, SnS2, SnSe2, SnTe2, RuS2, RuSe2, RuTe2, GaS, GaSe, GaTe, InS, InSe, HfS2, ZrS2, VS2, ReS2, and NbS2.
SOLUBLE BACTERIAL AND FUNGAL PROTEINS AND METHODS AND USES THEREOF IN INHIBITING AND DISPERSING BIOFILM
The present disclosure relates to methods of treating or preventing a biofilm-related infection and methods of preventing and treating biofilm formation on indwelling medical devices, implants, and non-medical surfaces comprising administering at least one soluble microbial protein that is encoded by an exopolysaccharide biosynthetic operon or functional gene cluster, wherein the protein comprises a glycosyl hydrolase domain. The present disclosure further provides particular soluble glycosyl hydrolases and compositions thereof.
Magnetic actuated microscaffold for minimally invasive osteochondral regeneration
Provided is a magnetically actuated microscaffold for minimal invasive osteochondral regeneration. More particularly, provided is a composition for cartilage regeneration, a microscaffold for cartilage regeneration, in which magnetic particles and cartilage regeneration cells are loaded on the surface of or within a 3-dimensional porous microstructure composed of a biodegradable polymer and having a diameter of 200-300 μm; and a microscaffold for bone regeneration, in which magnetic particles and bone regeneration cells are loaded on the surface of or within a 3-dimensional porous microstructure composed of a biodegradable polymer and having a diameter of 700-900 μm.
Titanium plasma coated medical grade thermoplastic or polymer proximal and distal interphalangeal toe implant
A medical grade thermoplastic or polymer implant with an osteoconductive coating is provided, specifically for corrections of the distal and proximal interphalangeal toe joints of the foot. The implant can be either straight or angled, and can be either solid or cannulated for insertion. The implant is sized and shaped depending on the specific anatomy and desired correction. End portions of the implant may be coated with an osteoconductive coating that promotes bone growth, but may reduce radiolucency. Thus, a central portion of the implant may remain uncoated to increase radiolucency of the implant at the region where two bones come together.
Biomaterial compositions
Biomaterial compositions comprising organosilicon monomers (such as silorane monomers) and chemical curing systems or dual chemical/light curing systems, in conjunction with optional tetraoxaspiro[5.5]undecanes (“TOSUs”) and/or fillers.
Full-Ceramic Resurfacing Prosthesis Having a Porous Inner Face
The invention relates to a resurfacing prosthesis for the natural femoral head, having a spherical outer surface and an inner receiving space that has an inner surface facing the bone. In order to be able to make the resurfacing prosthesis without using metals, combine the advantages of bone-preserving surgery with those of a biocompatible material, keep wear of the sliding pair low, and anchor the prosthesis in an excellent and long-term stable manner in the bone, the resurfacing prosthesis is characterized by an integrated porous osseointegrative inner surface and by an entirely ceramic design of the resurfacing prosthesis.
ORTHOPEDIC DEVICE AND POLYMER COMPOSITIONS FOR MAKING SAME
Orthopedic devices are described including polymer compositions used to make the devices. The polymer composition contains a polyoxymethylene polymer in combination with various additives that prevent against agglomerations and spotting even when the composition contains significant amounts of coloring agents and/or waxes. In addition, the polymer composition has reduced formaldehyde emissions and excellent thermal stability properties.
Orthopaedic Implants Having Self-Lubricated Articulating Surfaces Designed to Reduce Wear, Corrosion, and Ion Leaching
An orthopaedic implant can replace a joint in a patient. The orthopaedic implant includes a first component having a first component surface and a second component having a second component surface. The first component surface and the second component surface mate at an interface. The first component surface includes a metal substrate, a nanotextured surface, a ceramic coating, and a transition zone. The nanotextured surface is disposed directly upon the metal substrate and has surface features in a size of 10.sup.−9 meters. The ceramic coating conforms to the nanotextured surface and includes a plurality of bio-active sites configured to attract and retain calcium and phosphorous cations. The transition zone is disposed between the metal substrate and the ceramic coating. The transition zone includes a concentration gradient transitioning from the metal substrate to the ceramic coating and there is no distinct interface between the metal substrate and the ceramic coating.
Resilient interpositional arthroplasty device
This disclosure is directed to a resilient interpositional arthroplasty implant for application into a joint to pad cartilage defects, cushion, and replace or restore the articular surface, which may preserve joint integrity, reduce pain and improve function. The implant may endure variable joint compressive and shear forces and cyclic loads. The implant may repair, reconstruct, and regenerate joint anatomy, and thereby improve upon joint replacement alternatives. The walls of this invention may capture, distribute and hold living cells until aggregation and hyaline cartilage regrowth occurs. The implant may be deployed into debrided joint spaces, molding and conforming to surrounding structures with sufficient stability so as to enable immediate limb use after outpatient surgery. Appendages of the implant may repair or reconstruct tendons or ligaments, and menisci by interpositional inflatable or compliant polymer arthroplasties that promote anatomic joint motion.
Super elastic zirconium alloy for biological use, medical instrument and glasses
Provided is a super elastic alloy for biological use having a high biocompatibility, good processability and super elasticity, said super elastic alloy being a super elastic zirconium alloy for biological use comprising 27-54 mol % inclusive of titanium, 5-9 mol % inclusive of niobium which is a β phase-stabilizing element capable of stabilizing the β phase of zirconium, and 1-4 mol % inclusive in total of tin and/or aluminum which are ω phase-suppressing elements capable of suppressing the ω phase of zirconium, with the balance consisting of zirconium and inevitable impurities.
