Publication number: 20100023038Abstract: The subject invention pertains to an elastic sheath, device, and methods for disrupting and/or removing occlusive material from lumens, particularly biological lumens, such as the vasculature, ureter, urethra, fallopian tubes, bile duct, intestines, and the like. The subject invention provides for effective disruption and removal of occlusive material, such as a thrombus, from the body lumen with minimal risk of injury to the lumen wall. Advantageously, the invention can be used to achieve a high degree of removal while minimizing the amount of occlusive material that is released into the body lumen. The subject invention further pertains to methods for disrupting and removing occlusive material from a biological lumen. In another aspect, the present invention concerns a device useful as an in vitro model of luminal occlusion and methods for using the device to test the efficacy of devices and methods for treating luminal occlusions.Type: ApplicationFiled: October 6, 2009Publication date: January 28, 2010Applicant: UNIVERSITY OF FLORIDA RESEARCH FOUNDATION, INC.Inventors: Swadeshmukul Santra, Robert A. Mericle, Christopher D. Batich, Jessie T. Stanley, Eric Eskioglu

Publication number: 20050131458Abstract: A flowable, biodegradable endovascular embolic composition effective for embolizing a vascular defect consisting essentially of: (a) a biocompatible, biodegradable polymer or polymeric material forming composition; (b) a biocompatible embolic solvent for the polymer or polymer forming composition capable of diffusion into mammalian tissue; (c) biocompatible magnetic particles responsive to a magnetic field; wherein: the polymer or polymeric forming material and solvent are present in the composition in amounts and relative proportions such that (1) the composition is deliverable to a vascular defect site and (2) upon delivery to the site, solidifies into an embolic mass; and the magnetic particles are present in the composition in an amount sufficient to enable the composition being deliverable to the vascular site by a magnetic field. Also disclosed are methods and articles of manufacture embodying the above-described composition.Type: ApplicationFiled: August 9, 2004Publication date: June 16, 2005Inventors: Christopher Batich, Matthew Eadens, Robert Mericle, Matthew Burry, Courtney Watkins, Swadeshmukul Santra, Patrick Leamy

Publication number: 20030236457Abstract: Disclosed are the following strategies for endovascularly mapping the brain with a chemical agent capable of staining the preselected region of the brain to a color visibly contrasting with non-stained portions of the brain and of passing through the blood-brain barrier to the preselected region of the brain: 1) Passive transport: (a) pro-drug, (b) Modification of mapping agent to mimic molecules that readily cross the BBB (e.g., amino acid, glucose, etc.); 2) Active transport; 3) Receptor-mediated transport (e.g., antibody mediated); 4) Blood brain barrier (BBB) manipulation; 5) Emulsification of agent (such as carotene, organic dye, etc.) to stain capillary endothelium; 6) Embolization of brain capillaries; 7) Grafted-nanoparticle systems for brain delivery of mapping agent.Type: ApplicationFiled: April 24, 2003Publication date: December 25, 2003Inventors: Robert A.
