Patent number: 10443738Abstract: Systems and methods for providing a magnetic fluid (MF) seal suitable for a fluid environment may provide a shaft and a magnet that is cylindrical or ring-shaped. A magnetic fluid may be present between the magnet and shaft. Additionally, pole pieces may also be provided, which are also cylindrical or ring-shaped. These pole pieces are positioned on the shaft so the magnet is sandwiched between the pole pieces. The magnet, pole pieces, and shaft, if magnetic, may attract and retain the magnetic fluid in an annular gap or region between the shaft and the magnet and/or the pole pieces. The magnetic fluid in the annular gap serves as a seal or barrier that prevents fluid from passing through when pressure is below a predetermined level.Type: GrantFiled: June 19, 2017Date of Patent: October 15, 2019Assignee: PROCYRION, INC.Inventors: Christopher A. Durst, Jason J. Heuring, Benjamin A. Hertzog, Yoshinori Mitamura

Publication number: 20030077317Abstract: Methods and compositions are provided for enhancing the bioadhesive properties of polymers used in drug delivery systems. The bioadhesive properties of a base polymer are enhanced by incorporating a short chain polymer with one or more free carboxylic groups into the base polymer to enhance the ability of the base polymer to adhere to a tissue surface such as a mucosal membrane. The short chain polymers can be incorporated within a wide range of base polymers including proteins, polysaccharides and synthetic biocompatible polymers. In one embodiment, short chain polymers can be incorporated within base polymers used to form or coat drug delivery systems, such as microspheres, which contain a drug or diagnostic agent. The short chain polymers can either be solubilized and blended with the base polymer before manufacture or else used as a coating with base polymers over existing systems.Type: ApplicationFiled: May 15, 2002Publication date: April 24, 2003Applicant: Brown University Research FoundationInventors: Camilla A.
