Abstract: Apparatus and methods for forming dilatation balloons and catheters including same are provided. The balloons are fabricated of a material such as a nylon or a polyamide material, and they have been inflated, non-distended working profile as well as a stretched inflated profile which is achieved by applying pressure through a dilation catheter or the like that is in excess of that needed to achieve the inflated, non-distended profile and which is adequate to effect dilation or the like up to a maximum pre-bursting pressure application. The maximum pre-bursting size of the balloon can be tailored depending upon the needs of the particular balloon within a wide range of possible maximum pre-bursting sizes. The apparatus and methods facilitate fabrication of the balloons which are subjected to longitudinal elongation and radial expansion.

Abstract: Apparatus and methods for forming dilatation balloons and catheters including same are provided. The balloons are fabricated of a biaxially orientable material such as a nylon or a polyamide material, and they have an inflated, non-distended working profile as well as a stretched inflated profile which is achieved by applying pressure through a dilatation catheter or the like that is in excess of that needed to achieve the inflated, non-distended profile and which is adequate to effect dilatation or the like up to a maximum pre-busting pressure application. The maximum pre-busting size of the balloon can be tailored depending upon the needs of the particular balloon within a wide range of possible maximum pre-busting sizes. The apparatus and methods facilitate fabrication of the balloons which are subjected to longitudinal elongation or axial orientation and biaxial or radial orientation.
