The present invention is an inflatable balloon which is enclosed by an expandable cover which becomes increasingly porous/permeable during expansion. The balloon is coated or enclosed with a matrix which contains a pharmaceutically active agent. During expansion of the balloon, the pharmaceutically active agent is released or extruded through the expandable cover into a body cavity such as an artery or vein. The present invention also provides for a method of treating a disease or condition by delivering the inflatable balloon to a particular body cavity.

The present invention relates to the unexpected discovery of compositions and methods for the treatment of growth plate defects. In certain embodiments, the methods prevent the growth of bony bars at the site of growth plate injury, thereby preventing growth arrest and/or deformity. In certain embodiments, the compositions comprise hydrogels comprising at least one biological factor capable of preventing bony bar formation.

A gas permeable layer capable of supplying hydrogen includes a thin layer, encapsulating a hydrogen production formula. An outer side of the thin layer is airtight. An inner side is air-permeable. An inner side surface has a plurality of small holes. The thin layer can be a single layer or a composite layer. The hydrogen production formula does not dissipate. The hydrogen production formula absorbs moisture in the air or liquid water, thereby generating hydrogen. The hydrogen is released onto the skin and into the human body through the small holes. The hydrogen production formula includes metal peroxides, metal hydroxides, or metal hydrides and aluminum powder, or microsilica. The gas permeable layer can be used in sanitary products including eye masks, mouth masks, face masks, cosmetic facial masks, bras, pasties, nursing pads, sanitary napkins (towels), diapers, panty liners, wound dressing, woundplasts, bandage gauze, decubitus pads.

Nano- to microscale liquid coacervate particles are provided. The liquid coacervate particles are produced by a process including stimulating a population of liquid droplets containing one or a mixture of components to induce a phase separation point of a first component, and maintaining stimulation at the phase separation point to form a coacervate domain of the first component within each of the droplets to form the liquid coacervate particles. The self-assembled nano, meso, micro and macro liquid coacervate particles and related coated substrates can have utility in drug delivery, bioanalytical systems, controlled cell culture, tissue engineering, biomanufacturing and drug discovery.

Zwitterionic microgels, zwitterionic microgel assemblies, their formulations and methods for their use.

Provided is a slow release composition to promote bone growth, the slow release composition comprising: an oxysterol encapsulated in a biodegradable polymer to control the release of the oxysterol. Methods of making and use are further provided.

Embodiments of the invention include drug delivery coatings and devices including the same. In an embodiment, the invention includes a drug delivery coating including a polymeric layer. The polymeric layer can include a hydrophilic outer surface. The coating can also include a matrix contacting the hydrophilic outer surface. The matrix can include a particulate hydrophobic therapeutic agent and a cationic agent. The polymeric layer can further include a hydrophilic polymer having pendent photoreactive groups and a photo-crosslinker including two aryl ketone functionalities. Other embodiments are also included herein.

Disclosed are various bioactive grafts and/or biocompatible materials and methods of making the same. In one embodiment, bone material is harvested from a donor. The harvested bone material is exposed to a lysing agent, the lysing agent configured to release growth factors and bioactive materials from cellular material of the harvested bone material. The harvested bone material is then rinsed with a rinsing agent. The pH of the harvested bone material is substantially neutralized. In another embodiment, an orthopaedic implant includes an antibacterial polysaccharide. The implant may also include an osteostimulative agent.

The present invention belongs to the field of medical materials. A nano-oxide/kaolin composite hemostatic antibacterial material includes an iron oxide/kaolin composite carrier, and zinc oxide supported on the surface of the composite carrier. The present invention further provides the preparation and application of the composite hemostatic antibacterial material. Furthermore, the present invention provides a hemostatic healing-promoting dressing including the composite hemostatic antibacterial material disclosed by the present invention. The present invention surprisingly finds from research that the zinc oxide and iron oxide/kaolin composite carrier have a synergistic effect, and further cooperated with a special loading morphology, the synergistic effect of the two is unexpectedly enhanced, the hemostatic property and antibacterial property of the material are effectively improved, and moreover, the rate of wound healing is further improved.
