The invention discloses a carbon fiber composite artificial bone and a preparation method thereof. The artificial bone includes a carbon fiber composite spring-like frame or includes a carbon fiber composite spring-like frame and a carbon fiber composite plate dowel, and the carbon fiber composite plate dowel is inserted into one end or both ends of a cavity of the spring-like frame or penetrates through the cavity of the carbon fiber composite spring-like frame. The preparation method includes: preparing a spring-like carbon fiber preform through a weaving technology by using carbon fibers as a raw material, performing densification and high-temperature purification treatment and preparing a wear-resistant coating to obtain the carbon fiber composite spring-like frame; and combining the carbon fiber composite spring-like frame with the carbon fiber composite plate bowel to obtain the artificial bone.

A biocompatible polymer hybrid nanocomposite coating on a surface of a substrate, such as titanium and its alloys. The coating can be achieved by an electrostatic spray coating, preferably using ultra-high molecular weight polyethylene (UHMWPE) as a matrix for the coating. For example, up to 2.95 wt. % carbon nanotubes can be used as reinforcement, as can up to 4.95 wt. % hydroxyapatite. A dispersion of CNTs and HA in the coating is substantially uniform. The tribological performance of such coatings include high hardness, improved scratch resistance, excellent wear resistance, and corrosion resistance compared to pure UHMWPE coatings.

A method for coating a medical implant applies at least one coating to at least one surface of the implant by plasma polymerization. The implant has pores sized in the nanometer range. The method stabilizes the pores. The plasma polymerization is conducted in the presence of a coating gas and oxygen. A coating parameter can be selected so that a rough surface of the implant is coated. An implant includes a membrane having pores sized in the nanometer range. A surface of the implant is at least partially coated with a plasma polymer. The interior of the pores is uncoated.

There is disclosed a method of improving the reliability of coating an implantable medical device, such as a stent, with bioactive material in the absence of a carrier material such as a matrix or polymer layer. The method involves cleaning volatile components from the exposed surfaces of the medical device, removing carbon deposits and then applying a uniform carbon layer in a controlled environment. The deliberately applied carbon layer masks impurities of the underlying native oxide layer and leads to more uniform bioactive material coating not only a over the surfaces of a single medical device but also from device to device within a batch and between batches of devices. This improves production as well as optimising the amount and release of drug on the medical device without the need for a carrier material.

An antibacterial member that maintains a high antibacterial property and a high osteoconductive property for a long duration is provided. The antibacterial member includes a DLC film (F-DLC film) 40 containing fluorine at least partially or entirely on an outermost surface of a base material 10. The F-DLC film has an element ratio (F/(F+C)) of 17% to 72% and a nanoindentation hardness of 2,000 MPa to 16,000 MPa. This maintains wear resistance and close contact, and obtains an antibacterial member that maintains a high antibacterial property and a high osteoconductive property for a long duration. The F-DLC film does not necessarily need to cover the entire outermost surface of the base material but may be disposed in a mottled pattern.

A film formation method is provided with a step for disposing a non-electroconductive long thin tube 102 in a chamber 101 in which the internal pressure thereof is adjustable, generating a plasma inside the long thin tube 102 in a state in which a starting material gas including a hydrocarbon is supplied, and forming a diamond-like carbon film on an inner wall surface of the long thin tube 102. The long thin tube 102 is disposed in the chamber 101 in a state in which a discharge electrode 125 is disposed in one end part of the long thin tube 102 and the other end part is open. An alternating-current bias is intermittently applied between the discharge electrode 125 and a counter electrode 126 provided so as to be separated from the long thin tube 102.

Superhydrophobic materials are disclosed and described, along with devices, surfaces, and associated methods. Such materials can be coated onto device surfaces, system surfaces, structures, and the like.

Provided are a laminated material used for a medical lubricating member, including a base material a, and a layer b which is disposed on the base material a and contains a polymer having a polysiloxane structure, in which the polymer contains an acrylic acid component, an acrylic acid ester component, an acrylamide component, and/or a styrene component as a constituent component, and the polymer contains a hydroxy group, a carboxy group, an amino group, an isocyanate group, an oxazoline ring, an epoxy group, a vinyl group, an ethynyl group, a sulfanyl group, an azide group, a trialkoxysilyl group, and/or an acid anhydride structure in a molecule; a medical lubricating member formed of this laminated material; and a medical device using this medical lubricating member.

An orthotopic artificial bladder endoprosthesis includes a casing made of a PGA fiber fabric; the casing having two first connectors for the connection with the ureters of a patient and a further connector for the connection with the urethra of a patient; an inflatable element inserted in the casing; the inflatable element being switchable between an inflated configuration, in which it supports and maintains in position the casing, and a deflated configuration.
