The invention relates to biomaterials based on plastics, such as polyaryl polyether ketone (PEK), and to methods for producing and using same. The following describes how a mechanically stable coating made of a porous bone substitute material, e.g. Nano Bone®, is applied to polyaryl polyether ketone (PEK), e.g. polyether ether ketone (PEEK), as a result of which the problem of poor cell adhesion on plastics surfaces of this kind can be solved. The bone substitute material can be applied both dry as a powder and also in a wet spraying method. The coating is a result of briefly melting the polymer surface and the resulting partial penetration of the previously applied layer. In the process, the molten polymer penetrates into nanopores of the bone substitute material and thus establishes a firm connection.

A medical device and a method and process for at least partially forming a medical device, which medical device has improved physical properties.

A valve for use in manufacturing of implantable medical devices is insertable into a bore of the medical device during a manufacturing process. The valve is configured to remain closed while the pressure differential between an internal volume of the implantable medical device and a surrounding environment is below a particular threshold and to open when the threshold is reached, thereby allowing air or other fluids to escape from the internal volume into the surrounding environment. The valves are particularly useful during certain types of coating processes that must be performed at or near vacuum and provide an effective way to prevent ingress of coating material into the internal volume of the implantable medical device.

A non-compliant medical balloon may be changed from a deflated state to an inflated state by increasing pressure within the balloon. The non-compliant medical balloon is composed of a woven fabric layer composed of at least two woven fabric fibers forming an angle. The angle remains substantially unchanged when the balloon changes from a deflated state to an inflated state.

A method is provided for producing an adhesive material (1) for a medical application such as a dressing. The method includes at least one step for coating a first surface (2b) of any substrate (4), called receiving substrate, using a layer of previously coated silicone on an anti-adherent liner (3). The silicone layer is an adhesive gel (2). The method further includes, prior to the coating step, a corona treatment step for the surface of the adhesive silicone gel that is intended to coat the receiving substrate (4).

Introduced here are methods, apparatuses, and systems for mitigating the contact pressure applied to a human body by the surface of an object, such as a chair, bed, or table. A pressure-mitigation apparatus can include a series of chambers whose pressure can be individually varied. When placed between a patient and a contact surface, a controller can vary the contact pressure on the human body by controllably inflating one or more chambers, deflating one or more chambers, or any combination thereof. By monitoring the pressure in each chamber over time, the controller can also gain an enhanced understanding of movement(s) performed by the human body when positioned on the pressure-mitigation apparatus.

A process of coating a medical device surface with peptide-based nanoparticles with antimicrobial and healing properties; a process to coat a polyurethane (PU) dressing with a cross-linkable polymer adhesive in which was immobilized LL37 peptide conjugated-gold (Au) nanoparticles (LL37NPs) suitable to be applied on wounds. by following the steps of: 1) preparation of medical device surface; 2) coating the surface with a cross-linkable polymer adhesive; 3) spreading of peptide-based nanoparticles over the surface coated with the photo cross-linkable polymer adhesive; 4) exposing the surface coated with the adhesive and the nanoparticles to UV light; 5) placing the surface in phosphate buffer to leach loosely bound nanoparticles. The process described herein may be employed in the production of wound dressings, bandages, PU catheters and medical tubings.

The present invention relates to a medical instrument which comprises a porous metal layer. Also described are methods for producing such a medical instrument. The porous metal layer can serve as a marking for use in imaging radiological methods such as, for example, x-ray or ultrasound images.

A method for manufacturing a coated item 10 in a chemical deposition reactor and a coated item produced by the method are provided. The method includes deposition of a first coating on a first surface of the item 10, and/or deposition of a second coating on a second surface of the item.

Provided are polymers having a repeating unit including at least one astaxanthin moiety. Also provided are processes for preparing the polymers and various uses thereof.
