The present invention relates to electrochemically initiated bioadhesive compositions comprising biocompatible polymers containing derivatives of diazonium, arylsulfonium, or diaryliodonium in general, and to their use in tissue fixation, in particular.

Therapeutic hydrogels in nonsurgical techniques to promote healing and regeneration of tissues whose structure and functions have been diminished due to chronic inflammatory disorders. More particularly, providing therapeutic and regenerative hydrogel compositions and their nonsurgical delivery to periodontal treatment sites to treat periodontal and peri-implant diseases. One delivery technique involves the injection of a sterile therapeutic biomimetic hyaluronic acid hydrogel tethered to at least one host modulating agent, such as tetrahydrocurcuminoids, THC, and at least one additional tissue regenerative agent, into the gingival connective tissue proper. The host modulating agent potentiates the periodontal tissue regeneration at the periodontal treatment site, while the biomimetic hyaluronic acid hydrogel serves in a dual capacity as a drug, a tissue regenerative agent carrier and as a biodegradable matrix around which the new connective tissue regenerates. Oral care gel and paste compositions may be used in a synergistic home-based oral care regimen.

Improved methods for synthesizing taurolidine, improved compositions or formulations comprising taurolidine and methods for reducing an amount of impurities in taurolidine are provided herein, among other things. The taurolidine may be substantially free of impurities. The taurolidine may be a polymorph, for example, Polymorph A or Polymorph B. The composition or formulation may comprise Low-Molecular-Weight (LMW) Heparin.

Disclosed herein is a method of producing high purity pentagalloyl glucose (PGG), analogues or derivatives thereof, at least 99.9% pure, by washing with dimethyl ether. PGG may be provided in a kit, including a hydrolyzer for dissolving the PGG and a saline solution. Also disclosed herein is a device for delivery of a therapeutic solution to a blood vessel. The device may be a catheter having an upstream balloon and a downstream balloon. The upstream balloon may be expanded to anchor the catheter and occlude antegrade blood flow. The downstream balloon may be expanded to occlude retrograde blood flow, creating a sealed volume within the blood vessel. The downstream balloon may have pores configured to deliver a therapeutic inflation solution into the sealed volume or a portion thereof. The downstream balloon may be expanded by the expansion of a balloon disposed inside the downstream balloon.

A dressing for treating a wound on a digit includes a digit contact layer configured to substantially prevent adherence of the dressing to the wound and an antimicrobial layer coupled to a wound-facing side of the digit contact layer. The antimicrobial layer includes an antimicrobial substance. A first roll is coupled to a non-wound-facing side of the digit contact layer and unrollable to cover the digit, the digit contact layer, and the antimicrobial layer and a second roll is coupled to the first roll and unrollable to cover the first roll, the digit, the digit contact layer, and the antimicrobial layer.

An antibacterial medical biomaterial includes an acellular small intestinal submucosal matrix material, an antibacterial gel layer located on a surface of the acellular small intestinal submucosal matrix material, and an absorbable fiber layer located on a surface of the antibacterial gel layer. Sulfadiazine silver is on the surface of the acellular small intestinal submucosal matrix material and/or within the acellular small intestinal submucosal matrix material. An absorbable fiber layer to which the sulfadiazine silver is attached, wherein the content of sulfadiazine silver in the absorbable fiber is 1 wt. %˜2 wt. %. The medical biomaterial is usable as an external medicine for treating wound infections relayed by burns or wounds, and for reducing the incidence of infection by using a conventional central venous catheter with a sulfadiazine silver antibacterial coating, so that the medical biomaterial loaded with sulfadiazine silver also has antibacterial activity consistent with sulfadiazine silver.

Angioplasty balloons coated with at least one limus drug, which may be in crystalline form, optionally with at least one excipient, and methods for manufacturing such coated angioplasty balloons.

The present invention relates to compositions based on: (a) a glycosaminoglycan or mixtures thereof; (b) one or more tocopherols, tocotrienols and mixtures thereof; and (c) a selected stabilizer. The composition is a solution, with the agents not chemically bound with each other. The component (a) can be hyaluronic acid (HA) or a salt thereof; the component (b) can be a polyether clathrate a cyclodextrin, or a combination of a fatty acid with an emulsifier; the component (c) can be α-tocopherols, β-tocopherols, γ-tocopherols, δ-tocopherols; α-tocotrienols, β-tocotrienols, γ-tocotrienols, δ-tocotrienols. Preferably component (c) is vitamin E. The agents strongly cooperate to provide enhanced and more stable viscoelastic properties, resulting in a product with higher resistance to thermal treatments like e.g. heat-sterilization, autoclaving, etc. The present compositions, optionally loaded with pharmaceutically and/or cosmetically active agents, are advantageously used in medical or cosmetic methods.

An implantable device and methods for preparing and implanting said device into a subject for use in treating a medical condition when implanted therein is disclosed. The device comprises at least one coaxial fibre of a hydrophilic polymer and a hydrophobic polymer, wherein at least one of said polymers is loaded with an agent that is active towards treating the medical condition.

An antimicrobial diapering device for one or more of inhibiting growth of a microorganism and killing a microorganism includes a diaper for diapering a user. The diaper comprises an outer layer, an inner layer, and a medial layer. The outer layer is substantially impervious to water. The inner layer is porous or wicking. The inner layer is impregnated with one or more of honey, an anthraquinone, and curcumin. The one or more of the honey, the anthraquinone, and the curcumin effect one or more of inhibiting growth of a microorganism and killing a microorganism. The medial layer is hydrophilic and is positioned between the outer layer and the inner layer. The medial layer absorbs moisture from urine and feces.
