Patent number: 11298217Abstract: 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.Type: GrantFiled: July 29, 2019Date of Patent: April 12, 2022Assignee: Vertera, Inc.Inventors: Wei-Hsiang Chang, Stephen Lee Laffoon, Christopher S.

Patent number: 10569479Abstract: Multiple processes for preparing porous articles are described. The porous articles can be in a wide array of shapes and configurations. The methods include providing a soluble material in particulate form and forming a packed region from the material. The methods also include contacting a flowable polymeric material with the packed region such that the polymeric material is disposed in voids in the packed region. The polymeric material is then at least partially solidified. The soluble material is then removed such as by solvent washing to thereby produce desired porous articles. Also described are systems for performing the various processes.Type: GrantFiled: August 20, 2013Date of Patent: February 25, 2020Assignee: Vertera, Inc.Inventors: Ali R. Mehrabi, Reza Mehrabi, Rishikesh K. Bharadwaj, Eugene Rozenbaoum, Frank Chica
