Process For Forming A Medical Device Balloon

View page
US Patent:
6863861, Mar 8, 2005
Filed:
Sep 28, 2000
Appl. No.:
09/672330
Inventors:
Xiao Kang Zhang (Ken) - Champlin MN, US
Daniel Horn - Shoreview MN, US
Nao Pao Lee - Brooklyn Park MN, US
Victor Leo Schoenle - Greenfield MN, US
Assignee:
Boston Scientific SciMed, Inc. - Maple Grove MN
International Classification:
B29C047/00
US Classification:
264530, 264516, 2642091, 2642093
Abstract:
A balloon blowing process which involves radial expansion of an extruded tubing segment which has been subjected to a stretching step prior to radial expansion, the process utilizing an internal pressure and a temperature which together cause at least a portion of the tubing to expand to an interior diameter (ID) which is greater than the interior diameter of the extruded segment prior to extrusion.

US Patent:
7217278, May 15, 2007
Filed:
Feb 13, 2001
Appl. No.:
09/781388
Inventors:
Daniel Keith Tomaschko - Savage MN, US
Daniel James Horn - Shoreview MN, US
Xiao Kang Zhang - Champlin MN, US
Nao Pao Lee - Brooklyn Park MN, US
Assignee:
Boston Scientific Scimed, Inc. - Maple Grove MN
International Classification:
A61M 29/00
A61F 11/00
US Classification:
606194
Abstract:
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.

View page
US Patent:
7892478, Feb 22, 2011
Filed:
Apr 19, 2004
Appl. No.:
10/827494
Inventors:
Ken Xiao Kang Zhang - Maple Grove MN, US
Jeffrey S. Lindquist - Maple Grove MN, US
Victor L. Schoenle - Greenfield MN, US
Scott Schewe - Eden Prairie MN, US
David Parsons - Princeton MN, US
Nao Lee - Brooklyn Park MN, US
Ying Xiong - St. Paul MN, US
Assignee:
Boston Scientific Scimed, Inc. - Maple Grove MN
International Classification:
B29C 49/00
US Classification:
264535, 264523
Abstract:
An immersion mold for a medical device balloon. The mold has a cavity adapted to receive a hollow parison expandable therein to form the balloon. The cavity has a length, a first end, a second end, and a cavity wall with inner and outer surfaces. The mold form cavity wall is provided with one or a plurality of through-holes along the length thereof to facilitate entrance and egress of a heated fluid.

Tube-In-Tube Balloon

View page
US Patent:
8168275, May 1, 2012
Filed:
Oct 24, 2011
Appl. No.:
13/279913
Inventors:
Nao Lee - Brooklyn Park MN, US
Ying Xiong - St. Paul MN, US
Joe Khammoungkhoune - St. Michael MN, US
John J. Chen - Plymouth MN, US
Assignee:
Boston Scientific Scimed, Inc. - Maple Grove MN
International Classification:
B32B 1/08
A61M 29/02
US Classification:
428 357, 606192
Abstract:
A tube-in-tube assembled parison for preparation of an elongated medical device. The parison if formed by assembling in tube-in-tube fashion a first tube of orientable polymer material and a second tube formed of orientable polymer material disposed around the first tube, with an adhesive tie layer disposed between the first and second tubes. The tubes are brought into contact to form a unitary parison. The adhesive may allow movement between the polymer layers during balloon blowing. The first tube, or the second tube, or both, may have been longitudinally pre-stretched after formation thereof but before assembly of the parison.
