Provided herein are methods of making degradable, additive-blended polymeric materials using microwave radiation and catalysts. The methods can include incorporation of therapeutic materials into the polymeric materials. There also are provided polymeric materials made by the methods and medical devices comprising the polymeric materials made by the methods.

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.

Disclosed herein are cohesive soft tissue fillers, for example, dermal and subdermal fillers, based on hyaluronic acids and pharmaceutically acceptable salts thereof. In one aspect, hyaluronic acid-based compositions described herein include a therapeutically effective amount of at least one anesthetic agent, for example, lidocaine. The present hyaluronic acid-based compositions including lidocaine have an enhanced stability and cohesivity, relative to conventional compositions including lidocaine, for example when subjected to sterilization techniques or when stored for long periods of time. Methods and processes of preparing such hyaluronic acid-based compositions are also provided.

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.

Hemostatic devices for promoting blood clotting can include a substrate (e.g., gauze, textile, sponge, sponge matrix, one or more fibers, etc.), a hemostatic material disposed thereon such as kaolin clay, and a binder material such as crosslinked calcium alginate with a high guluronate monomer molar percentage disposed on the substrate to substantially retain the hemostatic material material. When the device is used to treat a bleeding wound, at least a portion of the clay material comes into contact with blood to accelerate clotting. Moreover, when exposed to blood, the binder has low solubility and retains a majority of the clay material on the gauze. A bandage that can be applied to a bleeding wound to promote blood clotting includes a flexible substrate and a gauze substrate mounted thereon.

Disclosed are methods of promoting wound healing in a patient in need thereof comprising administering to the patient a composition comprising a neonatal fibrin scaffold. Further disclosed are in vitro methods for evaluating a target composition on human wound healing comprising a neonatal porcine plasma scaffold with the target composition and evaluating scaffold properties of the plasma sample.

Provided herein are in vivo gelling ophthalmic pre-formulations forming a biocompatible retinal patch comprising at least one nucleophilic compound or monomer unit, at least one electrophilic compound or monomer unit, and optionally a therapeutic agent and/or viscosity enhancer. In some embodiments, the retinal patch at least partially adheres to the site of a retinal tear. Also provided herein are methods of treating retinal detachment by delivering an in vivo gelling ophthalmic pre-formulation to the site of a retinal tear in human eye, wherein the in vivo gelling ophthalmic pre-formulation forms a retinal patch.

The invention relates to an arrangement (1) comprising at least one structural element (2) made of an absorbable material with an antibacterial effect with a mount, which possesses an aspect ratio greater than 10 and whereat the material is a rapidly corroding magnesium alloy. The invention further relates to a mount (10) with an arrangement (1) carried by the mount (10) comprising at least one structural element (2) made of an absorbable material with an antibacterial effect.

Disclosed herein are delivery systems including coated and uncoated yarns, yarn precursors, threads, fibers, and other substrates for the constant or near-constant release of active compounds, as well as methods for manufacturing such delivery systems. The yarns, yarn precursors, threads, fibers, and other substrates can include a cross-linked hydrophobic elastomer and an active compound. One or more coatings that are impermeable or substantially impermeable to the active compound may partially or fully occlude the yarn or substrate to control release rates of the active compound. The delivery systems may be used in a variety of applications, including the making of articles of clothing, textiles, and fabrics, and may be used in methods of treating various conditions and diseases.

The present invention concerns a method to prepare a filler with a hyaluronic acid, which has improved properties of chemical-physical stability over time and optimal viscosity for cutaneous injection. In particular the method comprises a first step in which the hyaluronic acid is crosslinked, and a subsequent step for the neutralization and hydration of the crosslinked hyaluronic acid.
