The present disclosure provides compositions, methods of preparing, and method of use of a composition comprising: (a) about 0.05 wt % to about 10.0 wt % ethylenediaminetetraacetic acid, a salt thereof, a chelating agent, or a combination thereof; (b) from about 2.0 wt % to 50.0 wt % ethanol (ET), isopropyl alcohol (IPA), or a combination thereof; and (c) from about 0.015 μg/mL to about 100.0 μg/mL chlorhexidine, a salt thereof, or a combination thereof. These compositions, as disclosed herein, eliminate greater the 95% of planktonic or biofilm cells from a central venous access device.

A hemostatic colloid and method of forming a hemostatic colloid for dispensing into a wound site to control bleeding is provided. The hemostatic colloid is comprised of collagen in microfibril, crystalline, powder or granular form and is mixed with a liquid thrombin solution to form a flowable collagen/thrombin hemostatic colloid.

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.

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.

Provided herein are stable liquid sealant formulations comprising fibrin monomers and a reversible fibrin polymerization blocking agent, methods of preparing and using the formulations.

An antiseptic composition for use as bone cement, in particular an antiseptic polymethylmethacrylate bone cement. The composition can be cured and comprises a pharmacologically tolerable salt of a monoperoxy dicarboxylic acid, whereby the salt of the monoperoxy dicarboxylic acid can be dissolved from the composition in the presence of water. Preferably, the salt of the monoperoxy dicarboxylic acid in the composition is used in the form of a powder, whereby the powder has a mean particle size of not more than 250 μm. Preferably, the salt of the monoperoxy dicarboxylic acid, in solution at room temperature, is not degraded within 5 min by the catalase enzyme.

Methods for forming and incorporating microparticles containing one or more active agents into adhesives are described. The methods involve spray drying a liquid of the one or more active agents and obtaining the active agent in a particulate form. The dry powder is then blended or otherwise incorporated with the adhesive of interest. Also described are various medical products utilizing the adhesive and one or more active agents in microparticle form, and related methods of use.

Disclosed herein are methods relating to manufacturing an embolizing agent precursor. Manufacture of the embolizing agent precursor may involve mixing a first component contained within a first container with a second component contained within a second container, the first component including a plurality of negatively charged gaseous components and a first stabilizer, the second component comprising a plurality of positively charged oil components, a second stabilizer, and a cationic surfactant. Further steps may include mixing the first component with the second component such that the first and second component are held together as a single agglomerated entity.

A biocompatible adhesive is provided comprising one or more water insoluble compounds of structure (1) wherein B is an oligomer derived from a polyester, polyether, polyalkylene glycol, polysilicone or polycarbonate with a MW<10,000 g/mol, Linker L is a urethane, urea bond, or amide bond; Linker L′ is a urethane or urea bond, A is a chain extender of Mw≤3000 g/mol comprising substituted or unsubstituted alkyl, cycloalkyl and/or aromatic groups, W is a terminal adhesive benzene-1,2-diol derivative or a terminal adhesive benzene-1,2,3-diol derivative, m is 0 or 1; and n is 0, 1, 2, 3 or 4; or a cross-linked polymer formed from said compounds. The compound(s) have a Tg lower than 25° C. The biocompatible adhesive is suitable for use without solvent.

The present inventors have developed printable collagen bioinks using unmodified type I collagen with mechanical and structural properties that facilitate application to tissue in a structured form. In particular, the compositions of the present invention may be used to apply collagen gels to tissue (e.g. eye) using two- or three-dimensional (extrusion) bioprinting techniques.
