  • Patent number: 8252339
    Abstract: A method for medical treatment was developed in which microspheres with novel properties are administered in a mammal. The microspheres are made using a novel process that results in microspheres with new combined properties of high density, low fracture, high swell capacity, rapid swell, and deformability following swell. These microspheres may be administered for void filling, tissue bulking, non-vasculature occlusion, body fluid absorption, and delivery of medications.

  • Patent number: 8062673
    Abstract: A method for embolization treatment was developed in which microspheres with novel properties are administered in a mammal. The microspheres are made using a novel process that results in microspheres with new combined properties of high density, low fracture, high swell capacity, rapid swell, and deformability following swell. These microspheres form occlusions with high durability, withstanding over 100 mm Hg (13.3 kPa) of pressure.

  • Patent number: 7794755
    Abstract: A process for producing microspheres was developed that provides microspheres with new combined properties of high density, low fracture, high swell capacity, rapid swell, and deformability following swell. The process is reliable and high yielding, and makes use of a low temperature azo initiator and a small molecule chlorinated solvent as the organic phase. The microsphere preparation made using the process is particularly useful in medical treatments such as embolization.

  • Patent number: 7744717
    Abstract: Provided are processes for enhancing the resolution of a thermally transferred pattern on an imaged thermal transfer receiver, wherein the imaged thermal transfer receiver comprises a surface having an exposed portion and a non-exposed portion of one or more thermally transferred layer(s), comprising: (a) contacting said surface with an adhesive layer for a contact period to provide a laminate; (b) separating said adhesive layer from the laminate to provide a treated thermal transfer receiver having a surface substantially free of said non-exposed portion of one or more thermally transferred layer(s). The processes are useful in the fabrication of electronic devices including thin film transistors, circuits, electromagnetic interference shields, touchpad sensors and other electronic devices.

  • Publication number: 20090143550
    Abstract: Ethylene and allyl- or vinylsilanes are efficiently copolymerized by certain late transition metal complexes containing selected bidentate or tridentate ligands. The resulting novel polymers may be crosslinked by moisture when vinylsilane contains groups bound to silicon which are hydrolyzable.

  • Patent number: 7053259
    Abstract: ?-Olefins are made in a modified plug flow reactor system by the oligomerization of ethylene using an iron complex of a selected diimine of a 2,6-pyridinecarboxaldehyde(bisimine) or 2,6-diacylpyridine(bisimine) as the oligomerization catalyst. The reactor is modified to add the iron complex at two or more points along the length of the plug flow reactor, the distance between addition points being dependent on the half-life of the active ethylene oligomerization catalyst.
