NON-COMPLIANT MEDICAL BALLOON

摘要

A non-compliant fiber-reinforced medical balloon comprises a first fiber layer and a second fiber layer embedded in a continuous matrix of thermally-weldable polymer material defining a barrel wall, cone walls and neck walls. The fibers of the first fiber layer have a pattern of different lengths and are divisible into a first group and a second group based on length. The length of the fibers of the second group varies progressively in accordance to their proximity to the fibers of the first group; the fibers of the second group closest to the fibers of the first group being longer than the fibers of the second group further from the fibers of the first group. The fiber of the second fiber layer winds circumferentially around the longitudinal axis of the balloon substantially over the entire length of the balloon.

主权项

1. A method for forming a medical balloon, comprising:
affixing a sheet comprising fibers to a mandrel; providing a thermally weldable polymer material over the mandrel; and heating the thermally weldable polymer material to encapsulate the fibers of the sheet therein.
