  • Patent number: 11938250
    Abstract: Embodiments of the disclosure include coatings comprising an oligomerized polyphenol layer. The oligomerized polyphenol layer can be used as an intermediate coated layer on a medical device that hydrogen bonds to a synthetic or natural polymer, which in turn can be used as a top coat or further associated with another coated layer. The multilayered coatings can provide properties such as hemocompatibility or lubricity. In other embodiments, the oligomerized polyphenol layer is used on a medical device as a hemostatic layer configured to contact blood and promote coagulation. The oligomerized polyphenol layer can also be used on the inner surface (e.g., inner diameter) of a medical device to prevent bacterial adherence. The oligomerized polyphenol layer can also be used on the surface of a in vitro diagnostic article, or a cell culture device to, promote adsorption of a biological molecule.

  • Patent number: 11931478
    Abstract: In various aspects, the present invention is directed to novel bioactive peptide loaded poly(propylene fumarate) (PPF) tissue scaffolds and related methods for their making and use. In various embodiments, these bioactive peptide loaded poly(propylene fumarate) tissue scaffolds are formed by forming a PPF structure or matrix using photochemical 3-D printing techniques and then loading that printed PPF structure or matrix with a bioactive peptides or other bioactive compounds that have, or have been functionalized to have, a thiol functional group at or near its terminus. The thiol groups on the bioactive peptides or other compound will react with exposed alkene functional groups on the PPF polymer matrix via a thiol-ene “click” reaction, thereby binding these bioactive peptides or other compounds to the tissue scaffolds. The bioactive peptide loaded PPF tissue scaffolds of the present invention are particularly useful in repairing bone defects.

  • Patent number: 11896686
    Abstract: Core-shell particles and methods of making and using thereof are described herein. The core is formed of or contains one or more hydrophobic materials or more hydrophobic materials. The shell is formed of or contains hyperbranched polyglycerol (HPG). The HPG coating can be modified to adjust the properties of the particles. Unmodified HPG coatings impart stealth properties to the particles which resist non-specific protein absorption and increase circulation in the blood. The hydroxyl groups on the HPG coating can be chemically modified to form functional groups that react with functional groups and adhere the particles to tissue, cells, or extracellular materials, such as proteins.

  • Patent number: 11872622
    Abstract: Proposed is a nitinol nanofiber with an average surface roughness that is enhanced through mechanical and chemical treatments. The enhanced surface roughness improves biocompatibility and promotes tissue growing, thereby improving the bioavailability of the nitinol nanofiber. The nitinol nanofiber undergoes infrared irradiation whereby the nitinol fiber exhibits improved tensile strength, elastic modulus, and maximum restorative stress. Therefore, fatigue fraction does not easily occur in the nitinol fiber even when the nitinol nanofiber has a constant roughness. The present invention provides bio-use or medical nitinol nanofibers that are highly biocompatible.
