Publication number: 20240115767Abstract: An alternating vacuum and pressure system for decellularizing a bone matrix includes piping having a first end open to atmospheric pressure and a second end open to atmospheric pressure, and a subset of piping that forms a loop, a chamber in fluid, at least one heating element configured to heat the piping, a pump, and a plurality of valves. The plurality of valves can be selectively opened or closed to form one of a plurality of configurations, including a pressure configuration in which operation of the pump in a first direction causes a fluid within the piping to travel toward the chamber such that pressure is applied to the chamber and a vacuum configuration in which operation of the pump in a second direction causes the fluid within the pipe to travel away from the chamber such that a vacuum is created on the chamber.Type: ApplicationFiled: October 11, 2022Publication date: April 11, 2024Applicant: EPIBONE, INC.Inventors: Sarindr BHUMIRATANA, Eric Meade JEFFRIES, Keith YEAGER

Publication number: 20220176019Abstract: The present invention relates to a method of treating a bone defect site in a patient. The method includes applying to the bone defect site a bone graft composition comprising a scaffold having a desired shape. The scaffold includes a biodegradable polymer and a ceramic material. The scaffold includes interconnected pores and an average porosity range of about 50% to about 90%, wherein the porosity is substantially uniform throughout the scaffold. The scaffold is bioresorbable and exhibits advantageous mechanical properties that mimic those found in natural bone. Methods of preparing the scaffolds and using them in skeletal tissue engineering applications (e.g., as bone grafts to repair osteochondral defects and ligaments) is also described.Type: ApplicationFiled: February 24, 2022Publication date: June 9, 2022Applicant: EPIBONE, INC.Inventors: Sarindr BHUMIRATANA, Eric JEFFRIES, Melanie HORWITZ
