Patent number: 6121042Abstract: An apparatus and method for sterilizing, seeding, culturing, storing, shipping, and testing three-dimensional tissue constructs is disclosed. The apparatus includes a fluid reservoir, a pump, at least one treatment chamber, and a means for controlling media flow characteristics around a tissue construct disposed within the treatment chamber, and for controlling movement of the construct itself, so as to simulate a variety of physiologic conditions. One exemplary embodiment of the invention includes a means for applying an axial stress to the construct. Applying an axial stress to the construct during seeding and culturing results in a tissue-engineered construct with cells and their fibers oriented in a manner which is more likely to possess long term dimensional stability and the patency of native vessels with normal physiologic function.Type: GrantFiled: December 31, 1997Date of Patent: September 19, 2000Assignee: Advanced Tissue Sciences, Inc.Inventors: Alvin Peterson, Lee K. Landeen, John Bennett, Jason Gee, Scott Chesla, Joan Zeltinger, James H. Flatt, Mark A. Applegate, Noushin Dunkelman, Stephen V. Kemmerrer

Patent number: 6060306Abstract: An apparatus and method for sterilizing, seeding, culturing, storing, shipping, and testing cartilage constructs is disclosed. The apparatus generally includes a treatment chamber and a means for varying the fluid flow and pressure within the treatment chamber during seeding and culturing. The application of pressure to the cartilage construct improves both the uniformity of seeding throughout the construct and facilitates the flow of nutrients to and removal of waste products from cells embedded in the construct. In this manner, a tissue-engineered cartilage construct with cells and their fibers oriented in a manner which is more likely to possess long term dimensional stability and the patency of cartilage with normal physiologic function may be formed.Type: GrantFiled: August 14, 1997Date of Patent: May 9, 2000Assignee: Advanced Tissue Sciences, Inc.Inventors: James H. Flatt, Mark A. Applegate, Alvin Peterson

Patent number: 5763267Abstract: An apparatus for the large scale culturing and packaging of cell suspensions, three dimensional tissue, and other biological systems is disclosed. The apparatus includes a plurality of flexible or semi-flexible treatment chambers comprising one or more individual culture pockets, a plurality of rigid spacers, an inlet fluid manifold, an outlet fluid manifold, a fluid reservoir, and a means for transporting fluid within the system. During treatment, liquid media is transported from the fluid reservoir to the inlet manifold, which will in turn evenly distribute the media to each of the connected treatment chambers and internal culture pockets. An outlet fluid manifold is also provided to ensure that each treatment chamber is evenly filled and to ensure that any air bubbles formed during treatment are removed from the treatment chambers. The treatment chambers are flexible or semi-flexible so as to provide for easy end-user handling during rinsing and application of the cultured transplants.Type: GrantFiled: April 16, 1996Date of Patent: June 9, 1998Assignee: Advanced Tissue SciencesInventors: Christine Kurjan, Mark A. Applegate, James H. Flatt, Dawn Orton Applegate, Nicole Bloom, Mark Baumgartner

Patent number: 5288618Abstract: A galactomannan heteropolysaccharide is prepared by fermentation of a previously unknown microorganism, named Erwinia sp. ATCC No. 55046. The polysaccharide has valuable properties as a thickening, suspending, stabilizing and lubricating agent in aqueous systems. It has a chemical composition of mannose, galactose and galacturonic acid in the approximate molar ratio of 5:3:2. The polysaccharide can be produced in high yield and volumetric productivity from a submerged culture fermentation of a low-cost, lactose-containing whey or whey permeate medium.Type: GrantFiled: April 29, 1992Date of Patent: February 22, 1994Assignee: Wisconsin Alumni Research FoundationInventors: Robert S.
