Abstract
A balloon for medical treatments such as percutaneous transluminal coronary angioplasty (PTCA), delivery of a vascular stents or stent grafts, employs reinforcement materials that are patterned so as to promote consistent folding of the balloon. Also disclosed are methods and apparatus for biocidal treatment using a balloon, including balloons with fiber fabric reinforcements.
Claims5
A foldable composite balloon, comprising:
- a wall having elongate reinforcement members, first portions, and second portions, said elongate reinforcement members running through both the first portions and the second portions in a braided or woven pattern;
- an arrangement of the elongate reinforcement members being such that the wall is stiffer in the second portions than in the first portions, whereby the balloon tends to fold along contours coinciding with the lower stiffness portions.
