  • Publication number: 20220226095
    Abstract: Devices and methods for making a polymer with a porous layer from a solid piece of polymer are disclosed. In various embodiments, the method includes heating a surface of a solid piece of polymer to a processing temperature and holding the processing temperature while displacing a porogen layer through the surface of the polymer to create a matrix layer of the solid polymer body comprising the polymer and the porogen layer. In at least one embodiment, the method also includes removing at least a portion of the layer of porogen from the matrix layer to create a porous layer of the solid piece of polymer.

  • Patent number: 10582998
    Abstract: The disclosure describes a method including manufacturing a shape memory polymer fabric with a collection of shape memory polymer fibers such that the resulting shape memory polymer fabric has a glass transition temperature of greater than 50 degrees centigrade. The method further includes training the shape memory polymer fabric with a pre-determined percentage of strain between an expanded shape and a contracted shape. The method further includes preparing a portion of the shape memory polymer fabric into a shape that is sized to cover two portions of a ruptured soft tissue of an animal with a mean body temperature below 40 degrees centigrade while the fabric has the predetermined percentage of strain stored in the expanded shape.

  • Patent number: 8871268
    Abstract: Methods of manufacturing a three-dimensional, biodegradable, thermoset polymeric network composition having desirable degradation and mechanical properties, comprising a macromer component cross-linked with a monofunctional acrylate-containing component. The macromer component can comprise a diacrylate-containing component polymerized with an amine-containing component, wherein the molar ratio of the diacrylate-containing component to the amine-containing component is greater than or equal to 1.
