Gore Enterprise Holdings, Inc. - Newark DE
International Classification:
A61M 31/00
US Classification:
60410306
Abstract:
The present invention provides a balloon which achieves diameters greater than 6 mm for securement to a catheter. The balloon includes an elastomeric generally hollow pressure expandable body which exhibits essentially radial symmetry and constant length when expanded under an internally applied minimum working pressure from an uninflated state.
An inflatable toroidal-shaped balloon for medical use is provided with a central opening traversing the balloon in an inflated state. The balloon is useful to achieve larger outer diameters than conventional balloons.

US Classification:
264521, 264510, 264523
Abstract:
A non-shortening catheter balloon having a longitudinal axis and an inflatable balloon able to be affixed to a catheter shaft is provided. The balloon has an uninflated length which remains relatively unchanged upon inflation and is formed of least two helically oriented wrapped passes of balloon materials at a balanced force angle. Methods of making this balloon are also provided.

International Classification:
A61M 25/10
US Classification:
60410306
Abstract:
Balloons are provided which are formed of at least one balloon material with micropleats distributed about the circumference of the balloon. The micropleats reduce the profile of the balloon and pull taut upon inflation to provide an essentially radial symmetry.

Abstract:
An inflatable device with at least two helically wrapped passes forming a tube and an inflation means connected to said tube is provided. The tube is configured and joined in at least one area forming a low profile continuous inflatable device with multiple cross-sectional segmented areas.
