20100241213 | Impedance Pump Used in Bypass Grafts - A pump installed inside a graft in a body such as the human body to force fluid such as blood through that graft. The pump can be one which operates totally from the outside of the graft, forcing fluid through the graft without extending inside the graft. The pump can be an impedance pump, that operates based on the fluidic mismatches between the graft, and other fluid carrying vessels within the human body. | 09-23-2010 |
20100261228 | MULTIPLEXED SITES FOR POLYMER SYNTHESIS - Disclosed herein are methods, devices, and other components for synthesizing polymers. In some embodiments, numerous sites can be multiplexed together to allow for effective nucleic acid synthesis. | 10-14-2010 |
20110033933 | METHOD APPLYING HEMODYNAMIC FORCING AND KLF2 TO INITIATE THE GROWTH AND DEVELOPMENT OF CARDIAC VALVES - A method for forming a cardiovascular structure in culture is provided. The method includes applying mechanical force to a cell population in culture such that a cardiovascular structure is formed. In some embodiments, the mechanical force is produced in culture medium by a pulsatile liquid flow with a retrograde component. The cell population can include stem cells or differentiated cells, or combinations of both. In particular embodiments, a cardiovascular valve is formed. Scaffolds for the support and growth of the cell population, and bioreactors including the scaffolds, are also provided. | 02-10-2011 |
20110125136 | INTRAVASCULAR DIAGNOSTIC AND THERAPEUTIC SAMPLING DEVICE - A device and methods for continuous precision blood sampling from a patient with a micro impedance pump as the driver in a microfluidic system. Depending on the needs of medical technologies, the micro impedance pump in the intravascular diagnostic and therapeutic sampling system serves in a forward pumping function for blood sampling, in a backward infusing for therapeutic treatment, and in a valving function for controlling fluid flow. | 05-26-2011 |
20110236619 | FABRICATION OF ANCHORED CARBON NANOTUBE ARRAY DEVICES FOR INTEGRATED LIGHT COLLECTION AND ENERGY CONVERSION - A method of fabricating optical energy collection and conversion devices using carbon nanotubes (CNTs), and a method of anchoring CNT's into thin polymeric layers is disclosed. The basic method comprises an initial act of surrounding a plurality of substantially aligned nanostructures within at least one fluid layer of substantially uniform thickness such that a first end of the plurality of nanostructures protrudes from the fluid layer. Next, the fluid layer is altered to form an anchoring layer, thereby fastening the nanostructures within the primary anchoring layer with the first ends of the nanostructures protruding from a first surface of the primary anchoring layer. Finally, a portion of the anchoring layer is selectively removed such that a second end of the nanostructures is exposed and protrudes from the anchoring layer. The resulting product is an optically absorbent composite material having aligned nanostructures protruding from both sides of an anchoring layer. | 09-29-2011 |
20120021164 | METHOD FOR SELECTIVELY ANCHORING AND EXPOSING LARGE NUMBERS OF NANOSCALE STRUCTURES - Methods for fastening nanoscale structures within an anchoring structure to form a nanostructure composite and nanostructure composites formed therefrom. A primary fluid layer is formed on an anchoring substrate. Nanostructures are provided on an initial substrate, the nanostructures having a defined height and orientation with respect to the initial substrate. The nanostructures are introduced to a desired depth in the primary fluid layer, such that the orientation of the nanostructures relative to the growth substrate is substantially maintained. The primary fluid layer comprises one or more fluid layers. Ones of multiple fluid layers are selected such that when altered to form an anchoring structure, a portion of the anchoring structure can be removed, permitting exposure of at least a portion of the nanostructures from the anchoring structure in which they are affixed. The growth substrate is removed. Ends or other parts of nanostructures may be exposed from the anchoring structure. | 01-26-2012 |
20130041319 | Medicament Delivery Systems - Described herein are systems, devices, and methods for the delivery of substances to, or the sampling of substances from, a patient using a portable and preferably implantable device. The substances introduced to and/or taken from the patient are preferably fluidic and are driven by a miniature pump, such as a microimpedance pump. A number of design variations are explicitly and implicitly described, such as the use of multiple pumps and multiple reservoirs for containing medicaments. Methods of manufacture of these systems and devices are also described, for instance, using molding, micromachining, or lithographic processes. | 02-14-2013 |
