Implantable medical product with permanently negatively charged surface
An entirely or partially implantable medical product with a negatively charged surface for repulsing bacteria has a superficially bonded substance with a permanently negative excess charge, which substance is inert against cells of the human body and the bacteria contained therein.
METHODS OF SURFACE FUNCTIONALIZATION OF ZIRCONIA-TOUGHENED ALUMINA WITH SILICON NITRIDE
Disclosed herein are methods for functionalizing the surface of a biomedical implant. The biomedical implant may be a zirconia-toughened alumina implant surface functionalized with silicon nitride powder for promoting osteogenesis.
STABILIZED ACTIVE OXYGEN-GENERATING ANTISEPTIC COMPOSITIONS, IRRIGATION SOLUTIONS, AND ARTICLES
A stabilized active oxygen-generating antiseptic composition is disclosed including at least one of an antiseptic mixture or an antiseptic polymer. The antiseptic mixture includes a persulfate distributed in a matrix of a sulfate wherein the antiseptic composition is characterized by a ratio of the sulfate to the persulfate of at least 8:2. The antiseptic polymer is formed by the reaction of a sulfate, a persulfate, and amino acid in a reaction solution having a ratio of the sulfate to the persulfate of at least 6:4 and a ratio of the amino acid to the sulfate and the persulfate combined of 1:2 to 2:1. An antiseptic irrigation solution is disclosed including the antiseptic composition dispersed in a solvent. An antiseptic article is disclosed including an article and at least one of the antiseptic composition or an antiseptic coating formed from the antiseptic composition disposed on a surface of the article.
IMPLANTABLE DEVICE HAVING ONE OR MORE SCREWS
An implantable device for mounting to a patient's bone includes a housing and at least one osseointegrating protuberance. The housing includes a surface having an abutting portion configured to abut the bone when the housing is implanted in the patient, the abutting portion defining a housing axis orthogonal to the surface. The at least one osseointegrating protuberance: extends from the surface of the housing; is adapted to abut the patient's bone; and has a substantially smooth shaft.

Examples of coated objects include contact lenses, pacemakers, pacemaker electrodes, stents, dental implants, rupture nets, rupture mesh, blood centrifuge equipment, surgical instruments, gloves, blood bags, artificial heart valves, central venous catheters, peripheral venous catheters, vascular ports, haemodialysis equipment, peritoneal dialysis equipment, plasmapheresis devices, inhalation drug delivery devices, vascular grafts, arterial grafts, cardiac assist devices, wound dressings, intermittent catheters, ECG electrodes, peripheral stents, bone replacing implants, orthopaedic implants, orthopaedic devices, tissue replacing implants, intraocular lenses, sutures, needles, drug delivery devices, endotracheal tubes, shunts, drains, suction devices, hearing aid devices, urethral medical devices, and artificial blood vessels.
Method for creating a mineral trioxide aggregate material with improved biological effects
A dental device is improved in its ability to produce hydroxyl apatite by having a layer of mineral trioxide aggregate (MTA) deposited thereon. A tile of MTA is prepared, heat treated and sintered to produce a micronized tile of MTA that can then be deposited by physical vapor depositions, hot isostatic pressing, molding or other conventional technique.
System and method for correcting scoliosis
A wedge has an outer perimeter and includes a top surface extending generally in a first plane and having a top osteointegration surface disposed thereon. A bottom surface extends in a second plane that extends obliquely with respect to the first plane. The first plane intersects the second plane outside the outer perimeter of the implant and includes a bottom osteointegration surface disposed thereon. A plurality of side surfaces extends between the top surface and the bottom surface and defines the outer perimeter, wherein at least a portion of the plurality of side surfaces is devoid of any osteointegration surface.
Thin-film micromesh medical devices and related methods
Thin-film mesh for medical devices, including stent and scaffold devices, and related methods are provided. Micropatterned thin-film mesh, such as thin-film Nitinol (TFN) mesh, may be fabricated via sputter deposition on a micropatterned wafer. The thin-film mesh may include slits to be expanded into pores, and the expanded thin-film mesh used as a cover for a stent device. The stent device may include two stent modules that may be implanted at a bifurcated aneurysm such that one module passes through a medial surface of the other module. The thin-film mesh may include pores with complex, fractal, or fractal-like shapes. The thin-film mesh may be used as a scaffold for a scaffold device. The thin-film scaffold may be placed in a solution including structural protein such as fibrin, seeded with cells, and placed in the body to replace or repair tissue.
METAL SUBSTRATE WITH ANTIBACTERIAL AND OSTEOINTEGRATIVE PROPERTIES FOR IMPLANTOLOGY APPLICATIONS
The present invention relates to a substrate of a metal, preferably titanium or a titanium alloy, having at least one surface coated with an oxide layer of the metal itself, said surface being modified and enriched with Ca, P, Ga, Sr, and, optionally, Ag by anodic spark deposition (ASD). The present invention also relates to a process for producing said substrate by applying the anodic spark deposition (ASD) technique to a substrate, optionally pre-treated, immersed in an electrolytic solution comprising Ca, P, Ga, Sr and, optionally, Ag. Finally, the present invention also relates to a prosthesis and a surgical implant comprising or preferably produced with said substrate, as well as the use thereof for the prevention of bacterial colonisation and promotion of osteointegration in implantology operations, preferably orthopaedic prosthetic implantology.
