DELIVERY SYSTEMS
Methods for manufacturing drug delivery systems are provided. The drug delivery systems may include a substrate coated with at least one polymer and at least one active compound. The substrate may include yarns, yarn precursors, threads, filaments, fibers, and/or other suitable substrates. The methods may include disposing a solution including a monomer and an active compound on the substrate. The methods may also include exposing the solution and the substrate to UV light to initiate polymerization of the solution.
DRUG-ELUTING SURGICAL ARTICLES AND RELATED METHODS
Disclosed herein is a biomaterial and a method of use thereof for treating a condition. A biomaterial of the disclosure can be, for example, a surgical article. Implantation of a biomaterial disclosed herein into a subject can treat, for example, cancer.
Implantable urological device with improved retrieval feature
A urological medical device having a retrieval string is provided. The retrieval string has a proximal end connected the device and an opposed distal end. In a first embodiment, the retrieval string is configured in an initial confined form which, following a period of deployment in a patient's bladder, changes to an unconfined form in which the distal end of the retrieval string is extendible into the urethra to enable extraction of the device from bladder by pulling the retrieval string. The device may include a bioerodible component which permits the retrieval string to take the unconfined form following degradation of the bioerodible component in vivo. In another embodiment, the retrieval string includes a ferromagnetic material, which can be magnetically captured to facilitate removal of the device from the bladder. The ferromagnetic retrieval string may be buoyant in urine.
DERMAL FILLER COMPOSITIONS FOR FINE LINE TREATMENT
The present invention provides highly injectable, long-lasting hyaluronic acid-based hydrogel dermal filler compositions which are particularly advantageous for correction of fine lines in the face.
MULTILAYERED PRIMARY CONTACT WOUND DRESSING
The wound dressing described herein can be used as a contact layer dressing. The wound dressing can be positioned between a wound bed and a secondary dressing. The wound dressing can include a layered construction. Each of the layers can include a bioresorbable sponge enclosed within a collagen-based film. The wound dressing can include a plurality of fluid channels that enable fluid flow from the wound bed toward the environment-face side of the wound dressing.
Wound Dressing
This invention relates to a packaged sterile wound dressing comprising a dressing saturated with a pain relieving composition, a method of providing pain relief due to a wound of a subject using said dressing, and a method of manufacturing the packaged sterile wound dressing.
STABLE WOUND CARE FORMULATION
The present invention relates to a sterile gel formulation suitable for use in filling a wound cavity and delivering an active ingredient thereto, the gel further having a pH range of 4.5 to 8.5, low bioadhesive strength and cohesive integrity and being formed from a polymer selected from among the group consisting of poly(vinyl) alcohol (PVA) polymer and a PVA-polyvinyl acetate copolymer, a cross-linker being a salt form of boron that produces borate ions in aqueous solution, at least one compound which has a beneficial effect as an active ingredient in the wound and at least one modulator, the modulator being a low molecular weight species that is capable of binding borate or PVA in aqueous solution through a mono-diol or di-diol formation and reduces the pH of PVA-borate hydrogels; wherein the gel is heat and/or gamma sterilised and contains less than 5% acetic acid and the polymer has a degree of hydrolysis of between 98% and 100% and a molecular weight of from 100,000 to 300,000 Daltons.
METHOD TO PREPARE A FILLER WITH HYALURONIC ACID BASE COMPRISING A NEUTRALIZATION STEP
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.

BIOCOMPATIBLE ORGANOGEL MATRICES FOR INTRAOPERATIVE PREPARATION OF A DRUG DELIVERY DEPOT
The present disclosure is directed to an organogel drug depot for use in delivering an active agent to a surgical site, such as an implant site, for instance an orthopedic implant site. The present disclosure is also directed to an organogel drug depot for use in a non-sterile environment and application to a non-sterile open wound site. In a further embodiment, there is disclosed a system for preparing an organogel drug depot including an organogel matrix comprising an organogelator and a biocompatible organic solvent, an active agent comprising solid particles, a container including at least one wall having an outer surface and defining a volume capable of containing the organogel matrix and active agent solid particles, and a heating component configured to contact the outer surface and supply an amount of heat to the container.
