An anchorage device is provided that is configured to surround an implantable medical device. The anchorage device includes a substrate having a hemostatic agent and an active pharmaceutical ingredient selectively positioned on the substrate. Kits, systems and methods are disclosed.

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.

The present disclosure relates to methods for embedding drug molecules into medical catheters, tubes, and other medical devices. The catheter, tube, or other medical device is capable of releasing drugs for extended periods of time. Drugs can be loaded into the wall thereof through diffusion from a solution, e.g., loading solution. A counterintuitive approach of using undissolved drug particulates in the solution is employed in some embodiments. The drug in the wall of the device and in the solution (which when stored may be referred to as a storage solution) can be in dynamic equilibrium, yielding stable and easy-to-manufacture products. Heat can be used to significantly speed up the drug loading.

Use of 10H-benzo[g]pteridine-2,4-dione derivatives as photosensitizers in the inactivation of microorganisms.

A method of corneal implantation with cross-linking is disclosed herein. In one or more embodiments, the method includes the steps of: (i) prior to implantation, treating an implant formed from donor corneal tissue or a tissue culture grown corneal stroma with a solution of sodium dodecyl sulfate (SDS), Triton X-100, benzalkonium chloride (BAK), Igepal, genipin, 100% glycerol, or alcohol for making the implant acellular, and for killing any bacteria, viruses, or parasites prior to implantation; (ii) implanting the implant into a recipient cornea; (iii) applying laser energy to the implant so as to modify the refractive power of the implant while being monitored using a Shack-Hartmann wavefront system so as to achieve a desired refractive power for the implant; and (iv) applying a cross-linking solution and irradiating the implant to cross-link the implant to prevent an immune response to the implant and/or rejection of the implant by a patient.

Disclosed are apparatus, compositions, and methods for promoting regeneration of tissue on a subject such as a wounded, damaged, or injured appendage, or within a subject such as a wounded, damaged, or injured organ. The disclosed apparatus, composition, and methods include or utilize wearable sleeves and regenerative compositions.

A composition, comprising: a physiologically-acceptable polydimethylsiloxane having a surface; and one or more normal C.sub.6-C.sub.20NR.sub.1R.sub.2 saturated amine, salt thereof, or combination thereof, in contact with the polydimethylsiloxane, the surface, or both, wherein R.sub.1 and R.sub.2 may be same or different and independently selected from H, —CH.sub.3, —CH.sub.2CH.sub.3, —CH.sub.2CH.sub.2CH.sub.3, or combination thereof.

The present disclosure provides a medical adhesive and a preparation method thereof, comprising a component A and a component B: the component A comprises a cycloketene acetal compound and an oxidizing agent; the component B comprises a vinyl monomer, a cross-linking agent and a reducing agent, wherein the cycloketene acetal compound is selected from one or more of 2-methylene-1,3-dioxepane, 2-methylene-4-phenyl-1,3-dioxolane, 5,6-benzo-2-methylene-1,3-dioxepane and 4,7-dimethyl-2-methylene-1,3-dioxepane. The medical adhesive overcomes the disadvantages of conventional medical adhesives.

A collagen scaffold for the delivery of bioactive agents such as antimicrobials comprising a first collagen matrix layer and a second collagen matrix layer in which the first collagen matrix layer comprises a first bioactive agent physically entrapped in the first collagen matrix layer and the second collagen matrix layer comprises a second bioactive agent chemically attached to the second collagen matrix layer for an initial high concentration elution of antimicrobial from the first collagen matrix layer followed by a sustained release from the second collagen matrix layer to prevent re-infection.

In a medical instrument that is inserted into an affected area or tissue to perform treatment, a technique of delivering various drugs to a target site is desired.

Provided is a medical instrument that is inserted into an affected area or tissue to perform treatment, wherein a drug-loaded nanostructure is covalently bound to the medical instrument via a photosensitive linker immobilized on the surface of at least a portion of the medical instrument.
