Abstract: A three dimensional cell culture and bioreactor system is provided. The system comprises one or more cell culture chamber. Each cell culture chamber comprises an inlet port and an outlet port in fluid communication with the cell culture chamber. The cell culture chambers may be segregated or in fluid communication with one another. The systems may be used to conduct drug efficacy test, isolate certain cell types from a complex tissue sample of multiple cell types, allow for the ex vivo culturing of patient tissue samples to help guide the course of treatment, and conduct co-culture experiments.

Abstract: Embodiments disclosed herein are directed to bioreactor devices and systems that allow cultured cells to grow and develop with a three-dimensional aspect. In addition, the bioreactor systems described herein can be used for variation and independent control of environmental factors within the individual sub-wells which can be advantageously co-located in a common chamber. For example, the chemical make-up of a nutrient medium that can flow through a chamber as well as the mechanical force environment within the chamber, including the perfusion flow, shear stress, hydrostatic pressure, and the like, can be independently controlled and maintained for each separate culture chamber of the disclosed systems. Further, the bioreactor systems are designed for easy incorporation into automated systems and minimize or eliminate tubing.

Abstract: Disclosed are methods and devices for the engineering, formation, and post-formation handling of absorbent polymeric materials. Devices intended for use in a fluid environment that include an absorbent polymeric material can be formed and processed to ensure that upon installation of the device, the polymeric material can not only have the desired physical characteristics for the intended use, but can also be pre-equilibrated for the environment in which the device will be utilized. In particular, the polymeric materials can be formed with particular characteristics such that, upon absorption of a fluid, the characteristics will alter in a predetermined way to provide the materials within target specifications during use. In addition, the materials can be stored in a fluid so as to exhibit the desired operating characteristics immediately upon installation. In one particular embodiment, the invention is directed to biocompatible, implantable devices designed for use in vivo.

Abstract: An apparatus to facilitate precise and efficient evaluation of biomaterials using direct contact cell culture techniques. The apparatus positions the biomaterial and creates the potential to form a fluid-tight seal between the biomaterial and the apparatus, at which point the biomaterial is exposed to cells and/or media. An assay method based on the apparatus is claimed.

Abstract: A biocompatible, biodegradable, copolymer is prepared from cross-linking a polylactic acid with a polysaccharide such as dextran. The resulting copolymer is a biodegradable hydrogel or solid having both hydrophobic and hydrophilic properties and provides for a mechanism in which biologically active agents may be covalently bonded to the dextran prior to incorporation of the dextran into a copolymer, and the subsequent release of the biologically active agents as the copolymer degrades.
