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.

Abstract:

Composite fiber reinforced balloons for medical devices are prepared by applying a web of fibers to the exterior of a preformed underlayer balloon which has been pressurized and expanded to a predetermined pressure or above ambient size, encasing the web with a matrix material to form an assembly with the fiber web bonded to the underlayer balloon. The assembly may have an outer layer formed by inserting the assembly into a preformed outer layer balloon. The overlayer balloon can be bonded to the assembly during a heat set step.
