MEDICAL TUBE AND CATHETER
To reinforce a layer that is configured to contain fluororesin while suppressing the thickness of the entire medical tube. A medical tube includes a first resin layer that is configured to contain fluororesin, and a second resin layer that is configured to coat an outer peripheral surface of the first resin layer and containing polyimide resin. The thickness of the second resin layer is larger than 0 μm but not exceeding 15 μm.
Coated Medical Devices and Methods of Inhibiting Implant-Associated Infections
Methods for applying a coating to a surface of a substrate for inhibition and prevention of implant-associated complications (including implant-associated infections), methods for inhibiting and preventing implant-associated complications (including implant-associated infections), implant-associated infection inhibiting coatings, and coated devices are provided. Coating processes include a) providing a saturated or supersaturated solution of an antibiotic in a fast-evaporating or medium-evaporating organic solvent; b) coating the surface of the substrate with at least one application of solution, each application followed directly by a solvent evaporation period.
Modeling devices used in guided bone and tissue regeneration
This disclosure describes manufacturing of a device configured to guide bone and tissue regeneration for a bone defect. A method may include receiving a three-dimensional digital model or scan representing an anatomical feature to be repaired, generating a simulated membrane using the three-dimensional model, the simulated membrane being configured to cover the anatomical feature to be repaired, generating a digital two-dimensional flattened version of the simulated membrane, and generating code or instructions configured to cause a three-dimensional printer or milling device to produce a trimming guide that includes an opening corresponding to the flattened version of the simulated membrane and that further includes a cut-out configured to hold a premanufactured membrane. The trimming guide may be operative as a guide for marking or cutting the premanufactured membrane through the opening while the premanufactured membrane is held in the cut-out.
SURGICAL SYSTEM AND METHODS OF USE
A surgical device includes a substrate and a first coating that covers at least a portion of the substrate. The first coating includes a first polymer.

Medical device
The disclosed medical device has high visibility on non-woven fabric having a color such as green, blue, or the like, excellent identifiability from other medical devices having colors such as green, blue, or the like, and also a high adhesion property and strength of a coating. The medical device comprises an elongated body and a resin layer covering at least a proximal portion of the elongated body. The resin layer is comprised of a first layer which includes a first fluororesin, an organic pigment and titanium oxide, and a second layer which is formed on the first layer and includes a second fluororesin.
Layer by layer coated mesh for local release of bio-active proteins
The present invention relates to biomaterials coated with an active agent eluting coating, wherein implantation of the coated biomaterial results in reduced implant-related complications and/or improved integration of the biomaterial into the host tissue and further relates to kits containing the coated biomaterial. The present invention also relates to methods and kits for coating the biomaterial. It is based, at least in part, on the discovery that biomaterial coated with a cytokine eluting coating resulted in the shift of early stage macrophage polarization that were associated with positive long-term effects such as minimized capsule formation and improved tissue quality and composition as compared to uncoated biomaterials.
Hydrophilic lubricating coating for medical catheters and its preparation method
The invention discloses a photocured medical catheter hydrophilic lubricating coating and a preparation method thereof. The hydrophilic lubricating coating comprises a primer coating and a lubricating coating. The primer coating is attached to the surface of a device, and the lubricating coating is attached to the primer coating. The primer coating comprises 1-10 parts by weight of one or more polyester acrylates, 50-90 parts by weight of one or more solvents, 0.5-5 parts by weight of one or more photoinitiators, 0.5-2 parts by weight of one or more wetting agents and 0.5-5 parts by weight of one or more reactive (or active) diluents. The lubricating coating comprises 1-10 parts by weight of one or more water soluble macromolecules, 1-5 parts by weight of one or more crosslinking (or crosslinked) macromolecules, 0-1 part by weight of one or more photoinitiators, 0.1-1 part by weight of one or more surfactants and 50-98 parts by weight of one or more solvents. The preparation method of the hydrophilic lubricating coating is simple and easy in operation. Substance residues caused by complicated high-temperature chemical reactions are avoided. The cured coating forms a crosslinking (or crosslinked) structure, has good adhesion on the surface of a medical catheter and has excellent and lasting lubricity in an aqueous medium. The friction coefficient of the surface of the medical catheter is reduced. Harm to human tissues and adhesion of macromolecules in blood are decreased.
