Publication number: 20230415425Abstract: 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. Also described are systems for performing the various processes.Type: ApplicationFiled: September 11, 2023Publication date: December 28, 2023Inventors: Ali R. Mehrabi, Reza Mehrabi, Rishikesh K.

Patent number: 11780175Abstract: 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: January 13, 2020Date of Patent: October 10, 2023Assignee: NuVasive, Inc.Inventors: Ali R.

Patent number: 11168195Abstract: A method for making a composite and/or structured material includes: forming a lattice construction from a plurality of solid particles, the construction being formed so as to have one or more gaps between the particles; invading the lattice construction with a fluid material such that the fluid material at least partially penetrates the gaps; and, solidifying the material which invaded the lattice construction to form a composite material. In one suitable embodiment, the method further includes removing at least a portion of the lattice construction from the composite material thereby forming at the location of the removed portion one or more pores in the solidified material that invaded the construction.Type: GrantFiled: August 29, 2017Date of Patent: November 9, 2021Assignee: Avery Dennison CorporationInventors: Ali R.
