A method of coating a slip ring for use with a surgical instrument is disclosed. The method includes the steps of providing a slip ring including a plurality of conductive elements, and depositing a material less conductive than the conductive elements onto the conductive elements of the slip ring.

A coating layer, for example PEEK or titanium foil, shields a bone implant surface from wearing interactions with surfaces of bone and/or other implants. The coating prevents shedding particles which are difficult to distinguish from evidence of potentially dangerous conditions, for example, microorganism contamination and/or degenerating tissue. Methods and structures for securing a coating layer are described. Other uses and implementations of coating layers are described.

A surface coating for a medical instrument includes an interference filter having at least one dielectric layer and at least one metallic layer arranged one above another. At least one of the at least one metallic layer and the at least one dielectric layer is adapted to be structurally altered by action of a corrosive environment on the surface coating such that the surface coating is convertible from a first state to a second state. In the first state, the surface coating has a first spectral reflectivity. In the second state, the surface coating has a second spectral reflectivity that is different from the first spectral reflectivity.

Magnetic vascular grafts and methods for their use are provided herein.

A coated medical instrument can include a first layer bonded to a metal substrate surface of a medical instrument, a second layer bonded to the first layer, and a third layer disposed on the second layer, The first layer comprises chromium (Cr), hafnium (Hf), titanium (Ti), and/or niobium (Nb). The second layer comprises a nitride, oxide, carbide, carbonitride, or boride of chromium (Cr), hafnium (Hf), niobium (Nb), tungsten (W), titanium (Ti), aluminum (Al), zirconium (Zr), and/or silicon (Si). The third layer comprises a nitride, oxide, carbide, boride, oxynitride, oxycarbide, or oxycarbonitride of chromium (Cr), hafnium (Hf), niobium (Nb), tungsten (W), titanium (Ti), aluminum (Al), zirconium (Zr), and/or silicon (Si). Methods for making coated medical instruments are also disclosed herein.

A method for controlling generation of biologically desirable voids in a composition placed in proximity to bone or other tissue in a patient by selecting at least one water-soluble inorganic material having a desired particle size and solubility, and mixing the water-soluble inorganic material with at least one poorly-water-soluble or biodegradable matrix material. The matrix material, after it is mixed with the water-soluble inorganic material, is placed into the patient in proximity to tissue so that the water-soluble inorganic material dissolves at a predetermined rate to generate biologically desirable voids in the matrix material into which bone or other tissue can then grow.

The present invention discloses a process for the manufacture of a thin-film multilayered coating used in treating biomedical substrates and a coating in multilayered thin-film form (S/TiN/Ti/TiZr) to treat biomedical substrates used in surgical implants.

A surgical shaft is disclosed. The surgical shaft includes a proximal shaft portion including a proximal connector, where the proximal connector includes a proximal conductor assembly, and a distal shaft portion rotatable relative to the proximal shaft portion. The distal shaft portion includes a distal connector including a plurality of conductors operably engaged with the proximal conductor assembly. The plurality of conductors includes a first conductor and a second conductor, where the first conductor and the second conductor include a coating configured to prevent fluid from contacting the same.

An absorbable iron-based alloy implantable medical device includes an iron-based alloy matrix, a degradable polymer coating disposed on the surface of the iron-based alloy matrix, and a corrosion inhibition layer disposed on the surface of the iron-based alloy matrix. The corrosion inhibition layer can delay early-stage corrosion of the iron-based alloy matrix, ensure mechanical performance of a medical device in the early stage of the implantation, prevent degradation of a polymer in the early stage of the implantation of the medical device, and reduce the usage of the degradable polymer, thereby reducing risks of inflammatory reactions.

The present disclosure provides a medical instrument with a coating that provides excellent lubricity when wet. The medical instrument possesses a coating including a wet lubricating film with high peel durability and anti-eluting properties. In embodiments, an intermediate film made of bisphenol A type epoxy resin is coated on a base material of a medical instrument made of metal, and a wet lubricant coating produced by alkaline processing of a polymer alloy containing a methyl vinyl ether maleic anhydride copolymer and a polyether block amide is then applied thereto. Methods for making these medical instruments are also provided.
