Patent number: 7771450Abstract: Medical balloons and balloon preforms are made by methods which include the step of selectively removing material from the proximal and/or distal ends of a segment. In the case of a thermoplastic material characterized by one or more glass transition temperatures, the segment may optionally be maintained at a temperature below the glass transition temperature of the segment during the material removal step.Type: GrantFiled: May 14, 2007Date of Patent: August 10, 2010Assignee: Boston Scientific Scimed, Inc.Inventors: Daniel Keith Tomaschko, Daniel James Horn, Xiao Kang Zhang, Nao Pao Lee

Patent number: 7708928Abstract: Medical device balloons are formed from a tubular parison by a process or apparatus which establishes a controlled location (initiation zone) on the parison where radial expansion is initiated. Initiation within the initiation zone is achieved by heating the parison in that location to a higher temperature than the remainder of the parison for at least a portion of the blowing time. A variety of apparatus configurations are provided, some of which allow for the size and location of the initiation zone to be readily reconfigured. Balloons can also be modified, post-blowing, using heating apparatus and methods described.Type: GrantFiled: December 16, 2008Date of Patent: May 4, 2010Assignee: Boston Scientific Scimed, Inc.Inventors: Thomas Holman, Nam H. Hoang, Jeffrey S. Lindquist, Richard Dunn, Scott Schewe, Kevin Silberg, David Parsons, Ken Xiao Kang Zhang, Afsar Ali

Patent number: 6030375Abstract: The present invention is directed to a vaginal insert for delivering an agent to a urogenital tract in a patient. The patient has a vagina, and the vagina has a vaginal wall. The vaginal insert comprises a base member sized to fit within the vagina, the base member defines a chamber and a port in fluid communication with the chamber. A membrane is operatively connected to the base member. The membrane defines a reservoir and a pore. The reservoir is in fluid communication with the port. The membrane is sized so that the vaginal wall will exert pressure against the membrane when fluid is in the reservoir, thereby forcing some of the fluid to flow through the pore and to tissue of the urogenital tract.Type: GrantFiled: March 29, 1996Date of Patent: February 29, 2000Assignee: Iotek, Inc.Inventors: David W. Anderson, Robert E. Buuck, Arnold W. Thornton, Xiao Kang Zhang

Patent number: 5988169Abstract: A vaginal insert and method for delivering an agent to a urogenital tract in a patient, the patient having a vagina, the vagina having anterior and posterior walls. The vaginal insert comprises a main portion and first and second portions operably connected to the main portion. The first and second portions each have an end projecting outward from the main portion, at least one of the projecting ends has means for containing the agent. The projecting ends of the first and second portions are configured to engage the anterior vaginal wall while the main portion engages the posterior vaginal wall, thereby positioning the projecting end of the first portion proximal to one side of the urogenital tract and positioning the projecting end of the second portion proximal to an opposite side of the urogenital tract.Type: GrantFiled: March 29, 1996Date of Patent: November 23, 1999Assignee: Iotek, Inc.Inventors: David W.
