Lubricious one-part hydrophilic coatings
A lubricious coating for use on an implantable medical device includes a heterochelic component, a homotelechelic polymer and biocompatible initiator. Methods of forming such lubricious coatings are also provided.
Nanoparticle compositions and methods for treating or preventing tissue infections and diseases
Stabilized multi-component antimicrobial compositions for treating tissue diseases, infections or conditions include a first and second set of differently sized and/or differently shaped metal nanoparticles, and a stabilizing agent. Compositions and treatment methods may be used for treating tissue diseases, infections or conditions caused by microbial infections, such as bacteria, viral, and/or fungal infections, or for preventing the infection of a wound, such as a cut, abrasion, ulcer, lesion, sore, and the like. The compositions and treatment methods disclosed herein may also be used as a prophylactic, and in some embodiments may be applied to otherwise healthy tissue in order to prevent or reduce the occurrence of a tissue disease, infection or condition.
SI-O-N-P RELATED FABRICATION METHODS, SURFACE TREATMENTS AND USES THEREOF
Disclosed are compositions, methods and processes for fabricating and using a device or other implement including a surface or surfaces having a nanoscale or microscale layer or coating of Si—O—N—P. These coatings and/or layers may be continuous, on the surface or discontinuous (e.g., patterned, grooved), and may be provided on silica surfaces, metal (e.g., titanium), ceramic, and combination/hybrid materials. Methods of producing an implantable device, such as a load-bearing or non-load-bearing device, such as a bone or other structural implant device (load-bearing), are also presented. Craniofacial, osteogenic and disordered bone regeneration (osteoporosis) uses and applications of devices that include at least one surface that is treated to include a nanoscale or microscale layer or coating of Si—O—N—P are also provided. Methods of using the treated and/or coated devices to enhance enhanced vascularization and healing at a treated surface of a device in vivo, is also presented.
Coating composition, method of making a hydrophilic coating on a substrate, and medical device comprising such coating
The disclosure relates to a coating composition comprising a polymerizable compound of formula [1], wherein G is a residue of a hydrophobic hydroxy-functional oligomer, n is 1-10, each R1 independently is a residue of a C.sub.6-C.sub.20 aliphatic, cycloaliphatic, or aromatic hydrocarbon compound, and Z is a moiety having a polymerizable group; Formula [1] a hydrophilic polymer; a photo-initiator; optionally one or more further components, and a solvent. The polymerizable compound of formula [1] is typically present in an amount of 2.0-30 mass % based on total dry mass of the composition. Such coating composition can be made into a well-adhering single-layer hydrophilic coating on a surface of polymer substrates without providing a primer layer or chemically modifying the surface of the substrate. Upon wetting, the coating shows excellent lubricity and durability. In further aspects, the disclosure provides a method of applying a hydrophilic and optionally lubricious coating to an article; and an article like a medical device having on at least part of its surface a single-layer, hydrophilic and optionally lubricious coating, like a catheter, guidewire, or a delivery device for an implant.

Drug-coated balloon catheter and method for the production thereof
The invention relates to a drug-coated balloon catheter and to a method for producing the same. The balloon of the catheter includes (i) a main membrane, and (ii) an asymmetrical polymer membrane which is applied to an outside of the main membrane and into which at least one pharmaceutical active ingredient is introduced.
Osteoconductive coating of implants made of plastic
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.
RADIOACTIVE STENT
This disclosure provides design, material, preparation methods, and use alternatives for medical devices. An example method of preparing a stent comprises applying a coating to a portion of the stent at a medical treatment facility, the coating including a plurality of radioactive elements and a substrate. The plurality of radioactive elements are mixed with the substrate to form a mixture such that the plurality of radioactive elements are dispersed within the substrate prior to the coating being applied on the stent.
Cross-linked fatty acid-based biomaterials
Fatty acid-based, pre-cure-derived biomaterials, methods of making the biomaterials, and methods of using them as drug delivery carriers are described. The fatty acid-derived biomaterials can be utilized alone or in combination with a medical device for the release and local delivery of one or more therapeutic agents. Methods of forming and tailoring the properties of said biomaterials and methods of using said biomaterials for treating injury in a mammal are also provided.
BALLOON CATHETERS FOR BODY LUMENS
Various embodiments disclosed relate to drug-coated balloon catheters for treating strictures in body lumens and methods of using the same. A drug-coated balloon catheter for delivering a therapeutic agent to a target site of a body lumen stricture includes an elongated balloon having a main diameter. The balloon catheter includes a coating layer overlying an exterior surface of the balloon. The coating layer includes one or more water-soluble additives and an initial drug load of a therapeutic agent.
COMPOSITIONS AND METHODS FOR DELIVERING DRUGS TO A VESSEL WALL
