A system for managing female incontinence includes a body of biocompatible material configured to fit between the labia minora and the vestibule floor, the body having a surface configured to occlude the urethral meatus, an adhesive carried on at least a first portion of the surface and configured to provide a sealing engagement between the body and the urethral meatus, and a substance carried by at least one of the body and the adhesive and configured for controlling the odor of the general vaginal-urethral area of a female.

The present invention relates to an odor control material consisting of a water-insoluble particulate odor control agent and a thermoplastic water-soluble carrier matrix encapsulating the odor control agent. The carrier matrix dissolves when in contact with an aqueous solution, such as urine and the odor control material is obtained by means of thermoforming. The invention relates also to a method for the preparation of the odor control material and the use of the odor control material in absorbent products. The present odor control material minimizes dusting problems caused by particulate odor control agents in production processes.

The invention relates to a wound dressing which is particularly suitable for therapeutically dressing wounds. Said wound dressing consists of a multi-layered structure comprising at least one layer containing at least one hydrocolloid, preferably collagen, (“hydrocolloid layer” or “collagen layer”) and at least one layer containing an activated carbon (“activated carbon layer”).

A conductive hydrogel precursor solution cures after injection into the vasculature of the myocardium. The vasculature acts as a mold for the hydrogel and allows for a pacing signal to be conducted across the myocardium and not at a single point like traditional pacing leads. The catheter-based delivery can accurately place the hydrogels into the myocardial veins and can fill the venous tributaries. In situ crosslinking of the hydrogel precursor solution is achieved through several mechanisms, such as redox initiation by mixing a reducing reagent and oxidizing agent after injection. Conductivity is achieved by doping in conductive polymers or other conductive elements such as ionic species, metallic nanoparticles, or graphene nanoplatelets. To ensure long-term conductivity, hydrogel macromers may be synthesized without hydrolytically labile groups such as esters, and the conductive elements may be conjugated directly to the hydrogel matrix.

A composition to treat epidermal insults may have an ungraphenated detonation synthesis nanodiamonds (UDSND) and medical grade Siberian Sea Buckthorn Berry Oil (SBB) composition in a blended uniform composition with 1% hydrocortisone cream; wherein the UDSND are at 2 nm to 4 nm in initial crystal size and in the range of 0.2% to 0.5% of the UDSND-SBB composition weight and the SBB which is 99.5% to 99.8% of the UDSND-SBB composition weight; and wherein total composition ratio is in the range of about 3:1 to 10:1 hydrocortisone cream to UDSND-SBB composition. Preferably, the total composition ratio can be about 6:1 hydrocortisone cream to UDSND-SBB composition.

A composition of Poly(e-caprolactone)—PLC—and Graphene Oxide (GO) for use in killing bacteria that cause infections in patients implanted with medical devices, for example Staphylococcus epidermidis and Escherichia coli. Also disclosed is a method for constructing PLC/GO fibers and fibrous scaffolds by additive manufacturing and wet spinning, employing the composition and for example 3D printing. The method and compositions can be developed to produce a fibrous scaffold in which fiber diameter and PLC/GO concentrations are such that GO sheets are incorporated but at the same time exposed at the polymer surface, coffering bactericidal properties to the material, while keeping biocompatibility. Also disclosed is a fibrous PLC/GO bactericidal scaffold and the implanted medical devices having such scaffold. The composition, method, scaffold and medical devices may be used to achieve PLC/GO scaffolds and medical devices with bactericidal properties that have reduced risk of implant-associated infections.

The present disclosure relates to wound dressings that support the cells in the wound area for the treatment of chronic wounds and eliminates the risk of infection development in open wounds. Specifically disclosed is a wound dressing material that includes graphene-based 2,3 dialdehyde bacterial cellulose. Additionally disclosed is a method for preparing the graphene-doped bacterial cellulose wound dressing material.

Disclosed are a material with supercapacitance modified surface and a preparation method and application thereof. Specifically, the present disclosure introduces a material having a controllably supercapacitive surface. The surface is chargeable, the full-charged modified surface can interact with bacteria disturbing the electron transfer of respiratory chain of bacteria and inhibiting the growth and reproduction of bacteria in a short-term. The antibacterial rate can be improved by cyclically charging-discharging without losing capacitance, and prevent formation of biofilm of bacteria. The antibacterial system can quantitatively control the antibacterial process without affecting the biocompatibility of the material, and has the advantages of environmental protection and controllability.

Certain embodiments are directed to methods and compositions for inhibiting, stabilizing or preventing fungal infections by yeast on a surface using an agent comprising one or more types of quantum dots sufficient to regulate the growth of fungal cells or biofilms thereof.

An article having an antibacterial surface having an antibacterial surface having the nano scale flakes or platelets arranged essentially aligned to each other and extending out from said surface with a length in the range of 0.5-30 microns. The antibacterial surface is produced by processing a mixture of a polymer matrix material and a filler material comprising the nanoscale flakes or platelets by pressing the mixture through a die while heated to a temperature above a melting temperature of the polymer matrix material. Hereby, the nano scale flakes or platelets become aligned, with their longitudinal directions being oriented in substantially the same direction. A surface of the processed mixture which is oriented essentially perpendicularly to the longitudinal directions of the nano scale flakes or platelets is then etched or ablated to partly expose the nano scale flakes or platelets, thereby making the surface antibacterial.
