A polyelectrolyte complex includes nanofibers. The nanofibers include at least one polycationic component and at least one polyanionic component. The nanofibers have a diameter in a range of 20-100 nm. A process for preparing the complex, a method of using the complex, a kit which includes the complex, and a method of inhibiting loss of blood from a wound site by applying the complex to the wound site are also provided.

The present invention relates to large scale manufacture of nanoscale microsheets for use in applications such as wound healing or modification of a biological or medical surface.

The present invention relates to antimicrobial formulations. More particularly, the invention relates to monovalent copper-containing and/or monovalent copper-generating products for healing wounds and burns, and particularly for chronic wounds, prevention of wound infections and infections in various implants as well as medical/surgical devices.

This disclosure provides a hydrocolloid having a super absorbent material chemically bonded either directly or indirectly to a peroxide. The peroxide is within the hydrocolloid and the peroxide is in an amount of 0.05% to 2% by weight within the hydrocolloid.

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.

A barrier layer and corresponding method of making provide anti-inflammatory, non-inflammatory, and anti-adhesion functionality for a medical device implantable in a patient. The barrier layer can be combined with a medical device structure to provide anti-adhesion characteristics, in addition to improved healing, non-inflammatory, and anti-inflammatory response. The barrier layer is generally formed of a naturally occurring oil, or an oil composition formed in part of a naturally occurring oil, that is at least partially cured forming a cross-linked gel. In addition, the oil composition can include a therapeutic agent component, such as a drug or other bioactive agent.

Materials and methods for immobilizing bioactive molecules, stem and other precursor cells, and other agents of therapeutic value in surgical sutures and other tissue scaffold devices are described herein. Broadly drawn to the integration and incorporation of bioactive materials into suture constructs, tissue scaffolds and medical devices, the present invention has particular utility in the development of novel systems that enable medical personnel performing surgical and other medical procedures to utilize and subsequently reintroduce bioactive materials extracted from a patient (or their allogenic equivalents) to a wound or target surgical site.

The present invention relates to a composition that can be used as or as part of a wound dressing and to wound dressings comprising the same. More specifically, the present invention relates to a composition that disrupts and kills bacteria within a biofilm and also prevents biofilm formation. The solid composition comprises a first component selected from the group consisting of chitosan, chitin, derivatives of chitosan, derivatives of chitin, and combinations thereof; and at least one triprotic acid.

A packaged antimicrobial suture. The packaged antimicrobial suture includes an inner package having a source of antimicrobial agent, the source of antimicrobial agent comprising a plurality of patches, each patch having a pair of antimicrobial material reservoirs; at least one suture positioned within the inner package, the at least one suture comprising one or more surfaces; and an outer package having an inner surface, the outer package having the inner package positioned within; wherein the at least one suture, the inner package and the inner surface of the outer package are subjected to time, temperature and pressure conditions sufficient to transfer an effective amount of the antimicrobial agent from the antimicrobial agent source to the at least one suture and the inner package, thereby substantially inhibiting bacterial colonization on the at least one suture and the inner package. A method of making a packaged antimicrobial suture having is also provided.

The present invention discloses a preparation method of a biomedical titanium implant with a function of eliminating a surface biomembrane. The method includes the following steps: firstly synthesizing mesoporous polydopamine (MPDA) nanoparticles by a “one-pot method”, constituting a surface-aminated titanium material through diacid corrosion and modification of a 3-aminopropyltriethoxysilane (APTES) coupling agent, and integrating the MPDA nanoparticles into the surface of the titanium material through Michael addition reaction; secondly, taking MPDA anchored on the surface of the titanium material as a photothermal material and a photosensitizer carrier, where MPDA contains abundant aromatic rings capable of facilitating abundant loading of a photosensitizer (indocyanine green, ICG) through π-π stacking interaction; and finally further modifying biocompatible RGD polypeptides on the surface of MPDA by Michael addition reaction, where a modified titanium material is referred to as Ti-M/I/RGD.
