  • Publication number: 20220362161
    Abstract: Polymeric particles are provided for use in therapeutic and/or diagnostic procedures. The particles include poly[bis(trifluoroethoxy)phosphazene and/or a derivative thereof which may be present throughout the particles or within an outer coating of the particles. The particles may also include a core having a hydrogel formed from an acrylic-based polymer. Such particles may be provided to a user in specific selected sizes to allow for selective embolization of certain sized blood vessels or localized treatment with an active component agent in specific clinical uses. Particles of the present invention may further be provided as color-coded microspheres or nanospheres to allow ready identification of the sized particles in use. Such color-coded microspheres or nanospheres may further be provided in like color-coded delivery or containment devices to enhance user identification and provide visual confirmation of the use of a specifically desired size of microspheres or nanospheres.

  • Publication number: 20210299056
    Abstract: Various embodiments are directed to color-coded and size-calibrated polymeric particles comprising an acrylate-based hydrogel core incorporating one or more chromophores of interest, and an outer shell comprising polyphosphazenes of formula I, useful for various therapeutic and/or diagnostic procedures. In various embodiments, the color-coded and size-calibrated polymeric particles can be employed in any particle-mediated procedure, including as embolic agents, dermal fillers, and various implantable devices for a broad range of clinical and cosmetic applications. The incorporation of a particular chromophore formulation that correlates with a pre-determined size specificity for implantable and loadable polymeric particles (“color-coded and size-calibrated”) enables the visual detection and identification of particles exhibiting a particular size of interest, and minimizes the probability of user-introduced or procedural errors.
