Patent number: 7067316Abstract: The invention pertains to methods and devices for the long term, in vitroculture of hematopoietic progenitor cells in the absence of exogenously added hematopoietic growth factors, improved methods for the introduction of foreign genetic material into cells of hematopoietic origin, and to apparatus for performing these methods. The hematopoietic progenitor cells are cultured on a three-dimensional porous biomaterial. The three-dimensional porous biomaterial enhances hematopoietic progenitor cell survival and leads to an expansion of progenitor cell numbers and/or functionality, while maintaining progenitor cell pluripotency in the absence of exogenous growth factors. In addition, the three-dimensional porous biomaterial supports high level transduction on cells cultured upon such environment.Type: GrantFiled: November 10, 2003Date of Patent: June 27, 2006Assignee: Cytomatrix, LLCInventors: Mark J. Pykett, Michael Rosenzweig, Richard B. Kaplan

Patent number: 5855828Abstract: A refractory composite structure is formed which comprises a ductile refractory metallic layer with a roughened surface which is tightly bonded to a refractory composite structural shell. The roughened surface is preferably dendritic in form and produced by chemical vapor deposition techniques. The refractory composite structural shell is preferably a carbon-carbon composite formed by applying a carbon filament preform to the roughened surface, infiltrating the preform with a carbon matrix precursor, and carbonizing the precursor.Type: GrantFiled: June 7, 1995Date of Patent: January 5, 1999Assignee: UltrametInventors: Robert H. Tuffias, Brian E. Williams, Richard B. Kaplan

Patent number: 5283109Abstract: A high temperature resistant structure which is capable of withstanding temperatures well in excess of 2500 degrees Fahrenheit in oxidizing environments for periods of at least several hours. A high temperature resistant substrate such as carbon carbon composite is coated in situ with very thin alternate layers of silicon carbide and a carbide formed from hafnium or zirconium. The coating is preferably formed using chemical vapor deposition procedures.Type: GrantFiled: April 15, 1991Date of Patent: February 1, 1994Assignee: UltrametInventors: Richard B. Kaplan, Hugh O. Pierson, J. Grady Sheek, Robert H. Tuffias, Brian E. Williams

Patent number: 5282861Abstract: A tantalum open cell structure is formed by chemical vapor deposition onto a reticulated carbon foam substrate. Tantalum has a long history of use as an implant material, in both bone and soft tissue. This lightweight, strong, porous structure, mimicking the microstructure of natural cancellous bone, acts as a matrix for the incorporation of bone, providing optimal permeability and a high surface area to encourage new bone ingrowth.Type: GrantFiled: March 11, 1992Date of Patent: February 1, 1994Assignee: UltrametInventor: Richard B. Kaplan

Patent number: 3982148Abstract: A heat radiating coating of rhenium for a refractory core which may be used for a rotating X-ray anode, power tube or the like. The coating is characterized by a multiplicity of needle-like radiation-reflecting elements disposed adjacent to each other. The needles have such steep angles that incoming radiation is substantially absorbed thereby by repeated reflection. Since the coating has a high radiation absorption coefficient it has a corresponding high emissivity on the order of 0.9 at elevated temperatures. A process is disclosed for depositing such a heat radiating coating of rhenium by chemical vapor deposition.Type: GrantFiled: May 7, 1975Date of Patent: September 21, 1976Assignee: UltrametInventors: Richard B. Kaplan, Sebastian Gonnella, Walter M. Abrams
