Abstract: Described here are embodiments of processes and systems for the continuous manufacturing of implantable continuous analyte sensors. In some embodiments, a method is provided for sequentially advancing an elongated conductive body through a plurality of stations, each configured to treat the elongated conductive body. In some of these embodiments, one or more of the stations is configured to coat the elongated conductive body using a meniscus coating process, whereby a solution formed of a polymer and a solvent is prepared, the solution is continuously circulated to provide a meniscus on a top portion of a vessel holding the solution, and the elongated conductive body is advanced through the meniscus. The method may also comprise the step of removing excess coating material from the elongated conductive body by advancing the elongated conductive body through a die orifice.

Abstract: The present invention provides biodegradable, biocompatible bis-(?-amino acyl)-diol-diester-containing poly(ester amide) (PEA) and poly(ester urethane) (PEUR) co-polymer compositions with mechanical properties that can be readily tailored by selection of various combinations and proportions of the building blocks of the co-polymers. The compositions are suitable for use in production of drug-releasing biodegradable particles and implantable surgical devices, such as stents and internal fixation devices. The co-polymer compositions, particles and surgical devices biodegrade in vivo by enzymatic action to release bioactive agents in a controlled manner over time as well as biocompatible breakdown products, including one to multiple different amino acids.

Abstract: The present invention provides adhesion barrier compositions based on a solution of at least one of a biodegradable polyester amide (PEA), polyester urethane (PEUR), or polyester urea (PEU) polymers, dissolved in a biocompatible solvent. The compositions can be applied to a tissue surface, such as in open surgery, as a viscous liquid which forms an adhesive film upon being sprayed or painted onto the tissue surface. Alternatively, the composition can be applied to the tissue surface as a preformed solid layer or double layer (either porous or non-porous) that adheres to the tissue surface.

Abstract: The present invention provides wound healing or wound care polymer compositions that can be formulated to release a wound healing agent at a controlled rate by adjusting the various components of the composition. The compositiona can be used in an external wound dressing, as a polymer implant for delivery of the wound healing agent to an internal body site, or as a coating on the surface of an implantable surgical device to deliver wound healing agents that are dispersed in a biodegradable polymer or hydrogel, or both. Methods of using the invention bioactive polymer compositions to deliver wound healing agents that promote natural healing of wounds, especially chronic wounds, are also provided.
