Patent number: 7879270Abstract: A process for producing a dilatation balloon by extruding a multiblock copolymer composition to form an extrudate comprising phase-separated glassy, rubber, and semicrystalline microdomains that are macroscopically ordered in a perpendicular alignment. The balloon formed by the process demonstrates, during inflation, a true stress vs. nominal strain response curve comprising a first zone representative of a low modulus balloon, a second zone representative of a high strength balloon, and a sharp transition from the first zone to the second zone.Type: GrantFiled: August 26, 2010Date of Patent: February 1, 2011Assignees: Medtronic, Inc, Regents of the University of MinnesotaInventors: Ashish Varma, Kimberly A. Chaffin, Frank Bates, Marc Hillmyer, Lisa Lim

Patent number: 7867512Abstract: The present invention provides biocompatible vesicles comprising semi-permeable, thin-walled encapsulating membranes which are formed in an aqueous solution, and which comprise one or more synthetic super-amphiphilic molecules. When at least one super-amphiphile molecule is a block copolymer, the resulting synthetic vesicle is termed a “polymersome.” The synthetic, reactive nature of the amphiphilic composition enables extensive, covalent cross-linking of the membrane, while maintaining semi-permeability. Cross-linking of the polymer building-block components provides mechanical control and long-term stability to the vesicle, thereby also providing a means of controlling the encapsulation or release of materials from the vesicle by modifying the composition of the membrane. Thus, the encapsulating membranes of the present invention are particularly suited for the reliable, durable and controlled transport, delivery and storage of materials.Type: GrantFiled: February 20, 2007Date of Patent: January 11, 2011Assignees: The Trustees of the University of Pennsylvania, Regents of the University of MinnesotaInventors: Dennis E. Discher, Bohdana M. Discher, You-Yeon Won, James C-M Lee, Daniel A. Hammer, Frank Bates

Publication number: 20090140449Abstract: A self-wrapping dilatation balloon comprising a multiblock copolymer having high elasticity and elastic recovery from nominal strains greater than about 30% is described. Also described herein, is a polymeric extrudate for making a dilatation balloon comprising a multiblock copolymer having tensile strength in the range of about 50 MPa to about 450 MPa, strain at break in the range of about 50% to about 600% and substantially complete elastic recovery from nominal strains of at least about 30%. The extrudate has phase-separated microdomains that are macroscopically aligned in parallel, perpendicular, transverse or a combination thereof. Also described herein is a process for producing a polymeric extrudate for use as a dilatation balloon. The process comprises extruding a multiblock copolymer mixture or composition to form an extrudate.Type: ApplicationFiled: October 30, 2008Publication date: June 4, 2009Inventors: Ashish Varma, Kimberly A.

Publication number: 20070075914Abstract: This invention defines an apparatus and method for holding a portable electronic device whereby ease of use is continued, security is ensured and antenna reception is enhanced. The apparatus combines a metallic antenna inside an elastic spiral cord which attaches a cell phone, or other electronic device, with an attachment mechanism, such as a retaining clip, to a person's secure location, such as a waistband, belt, purse, backpack or other, suitably-shaped, receiving structure. The apparatus stretches approximately 24 inches from the secure location for normal use. If the electronic device is dropped the 24 inch stretched distance will most often prevent the device from being lost or damaged by hitting the ground. Simultaneously, the antenna conductive element within the apparatus will improve radio frequency transmission and reception performance for electronic devices.Type: ApplicationFiled: February 9, 2006Publication date: April 5, 2007Inventor: Frank Bates

Patent number: 4090758Abstract: The method comprises the steps of providing a camera tube having an evacuated envelope, a photoconductive layer primarily of lead monoxide, an activated getter and an unactivated getter within the envelope. After a period of operation or storage the tube exhibits a deterioration in spectral photosensitivity of the layer. The characteristic ratio of blue light photosensitivity is measured and when the ratio is less than about 80% the unactivated getter is activated to regenerate the tube.Type: GrantFiled: January 21, 1977Date of Patent: May 23, 1978Assignee: RCA CorporationInventors: Chih Chun Wang, Thomas Clifford Lausman, Ronald Frank Bates
