Medical device are provided for delivering a therapeutic agent to a tissue. The medical device has a layer overlying the exterior surface of the medical device. The layer contains a therapeutic agent and an additive. In certain embodiments, the additive has a hydrophilic part and a drug affinity part, wherein the drug affinity part is at least one of a hydrophobic part, a part that has an affinity to the therapeutic agent by hydrogen bonding, and a part that has an affinity to the therapeutic agent by van der Waals interactions. In embodiments, the additive is water-soluble. In further embodiments, the additive is at least one of a surfactant and a chemical compound, and the chemical compound has a molecular weight of from 80 to 750 or has more than four hydroxyl groups.

The disclosed technology provides thermoplastic polyurethane compositions having antimicrobial properties while still maintaining good physical properties and good non-fouling properties, methods of making the same, and articles, including medical devices, made from such compositions. The disclosed technology includes a process of making an antimicrobial polymer composition, where the process includes mixing an antimicrobial additive into a base polymer and further includes mixing in a non-fouling additive, where the antimicrobial additive is chemically held in the composition and the antimicrobial and non-fouling additives do not negatively impact each other's effectiveness.

A medical device for implantation in tissue includes: a header including one or more bores, the header including an implant grade thermoplastic resin including a conductive additive and a metal coating; one or more leads disposed in the header and exiting the header through the one or more bores; and an enclosure coupled to the header at a surface of the enclosure, the enclosure including circuitry and a power source. A sterilized header for an implantable enclosure is also described.

Antimicrobial metal ion coatings and implants including them. In particular, described herein are coatings including an anodic metal (e.g., silver and/or zinc and/or copper) that is co-deposited with a cathodic metal (e.g., palladium, platinum, gold, molybdenum, titanium, iridium, osmium, rhodium, manganese, niobium or rhenium) on a substrate so that the anodic metal is galvanically released as antimicrobial ions when the apparatus is exposed to a bodily fluid. The anodic metal may be at least about 25 percent by volume of the coating, resulting in a network of anodic metal with less than 20% of the anodic metal in the coating fully encapsulated by cathodic metal. The implant may be configured as an implant such as a bone-screw or intramedullary rod-like body configured to receive a treatment cartridge having a coating as described.

The present disclosure provides for a medical device or a substrate coated with polydopamine which is further linked to ligands such as antibodies and/or antibody fragments. The polydopamine coating and the ligands may be linked through a linker such as an organic polymer.

Drug delivery coatings and devices including the same are described herein. The drug delivery coating has a first coated layer with non-ionic polymer and photogroups, a second coated layer with acid polymer in contact and hydrogen bonded with the first layer, particles with hydrophobic therapeutic agent, and cationic agent. The coating can be provided on a balloon catheter, and the particles and cationic agent can be transferred to tissue during a medical procedure, such as an angioplasty procedure, for a therapeutic effect.

A method for depositing a coating comprising a polymer and at least two pharmaceutical agents on a substrate, comprising the following steps: providing a stent framework; depositing on said stent framework a first layer comprising a first pharmaceutical agent; depositing a second layer comprising a second pharmaceutical agent; Wherein said first and second pharmaceutical agents are selected from two different classes of pharmaceutical agents.

Embodiments of the invention include lubricious medical device coatings. In an embodiment the invention includes a coating for a medical device including a first layer comprising polyvinylpyrrolidone derivatized with a photoreactive group; and a first cross-linking agent comprising at least two photoreactive groups; a second layer disposed on the first layer comprising polyvinylpyrrolidone derivatized with a photoreactive group; a second cross-linking agent comprising at least two photoreactive groups; and a polymer comprising polyacrylamide, the polymer derivatized with at least one photoreactive group. Other embodiments are included herein.

Various aspects of the present invention provide compositions and implantable devices including a water-insoluble therapeutic agent solubilized in a matrix of a gallate-containing compound. Other aspects provide methods of manufacturing and using such compositions and devices.
