The invention relates to an antimicrobial coating composition for coating articles comprising: an antimicrobial peptide and a nanoparticle bound to said antimicrobial peptide; wherein the composition is suitable to be bonded to the surface of the article. The said composition could be used as coating composition of medical devices and laboratory surfaces.

The present invention describes chitosan gel (poly-beta-glucosamine) having bacteriocidal and fungicidal properties in a mixture with nanoparticles of copper and/or silver, and/or antibiotics (ciprofloxacin, cloxacillin, gentamicin and cefotamine, and a mixture of ciprofloxacin and cloxacillin, gentamicin and cefotaxim), and a process of obtaining and using the described gel.

The present disclosure is drawn to antimicrobial implantable medical devices, and can include an implantable medical device, and an antimicrobial metal applied to an exterior surface of at least a portion of the implantable medical that is positionable within a body tissue or traverses the body tissue when surgically placed (using surgical instruments beyond merely a needle or catheter port) for implantation.

The present invention generally relates to the use of small particles, such as micro particles or nanoparticles, to produce a therapeutic scar such as “trans-mural” scarring or other desired “deep tissue” scarring. In one preferred embodiment, these particles can be delivered to a target location by an implant. More specifically, these particles can be incorporated into the structure of implants or into the coatings on implants. In another preferred embodiment, these small particles can be delivered directly with a catheter by electrophoresis or hydraulic pressure.

In various embodiments, a tissue thickness compensator can comprise one or more capsules and/or pockets comprising at least one medicament therein. In at least one embodiment, staples can be fired through the tissue thickness compensator to rupture the capsules. In certain embodiments, a firing member, or knife, can be advanced through the tissue thickness compensator to rupture the capsules.

An implant is provided comprising a substrate having one or more nanoceria coatings coated at least partially thereon, wherein the one or more nanoceria coatings comprise surface cerium having a 3+/4+ oxidation state ratio such that the one or more nanoceria coatings exhibit catalase mimetic activity, superoxide dismutase mimetic activity, or both. Methods are provided for forming a nanoceria coating. The coating has nanoceria having a surface cerium 3+/4+ oxidation state ratio such that such that the coating exhibits catalase mimetic activity, superoxide dismutase mimetic activity, or both. Also disclosed is a method of reducing degradation of an implant by placing nanoceria in proximity to a bone-implant interface.

Provided is an inexpensive keratoconjunctival cover sheet that is comfortable and has good oxygen-permeability, contamination-resistance, wettability, handleability, and optical properties, and that can be used for medical treatment, visual correction, a cosmetic application, and the like. The keratoconjunctival cover sheet is constituted by a gel layer that includes metal ions and a water-soluble gelling agent exhibiting a gelation ability in the presence of the metal ions, and has a surface area capable of covering a cornea or keratoconjunctiva.

The present disclosure relates to a novel sericin-based hydrogel wherein the silk sericin is enzymatically cross-linked for an improved treatment of wound healing, ischemic diseases or cardiovascular diseases, namely chronic wound healing, in particular diabetic wound.

Antimicrobial metal ion coatings and implants including them. In particular, described herein are coatings including an anodic metal (e.g., silver and/or zinc and/or copper) that is co-deposited with a cathodic metal (e.g., palladium, platinum, gold, molybdenum, titanium, iridium, osmium, rhodium, manganese, niobium or rhenium) on a substrate so that the anodic metal is galvanically released as antimicrobial ions when the apparatus is exposed to a bodily fluid. The anodic metal may be at least about 25 percent by volume of the coating, resulting in a network of anodic metal with less than 20% of the anodic metal in the coating fully encapsulated by cathodic metal. The implant may be configured as an implant such as a bone-screw or intramedullary rod-like body configured to receive a treatment cartridge having a coating as described.
