Balloons for medical devices
First Claim
1. A balloon for a medical device catheter, the balloon having been made by a process comprising:
- providing a length of tubing made of a nylon material or of a polyamide material, said length of tubing having a predetermined original outer diameter and a predetermined original wall thickness;
radially expanding a section of said length of tubing into a balloon by inflating said section with a pressurized fluid in order to increase the diameter of said section to at least in excess of twice said original outer diameter of the length of tubing;
said balloon has a non-distended inflated profile having a predetermined size as well as a distended size that has a radius greater than that of said predetermined non-distended size, and said distended size has an inflated profile larger than that of said non-distended inflated profile; and
said balloon has a tensile strength greater than non-nylon cathether balloons that have an inflated profile exhibiting a distended size.

Abstract
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 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-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.

15. A medical catheter, comprising:
-
a catheter body; a balloon positioned along the length of said catheter body; said balloon being constructed of a nylon material or of a polyamide material tubing that had been radially expanded to a predetermined balloon diameter; said balloon has a collapsed profile at which the outer diameter of the balloon approximates the outer diameter of said catheter body, said balloon further having a non-distended inflation diameter at which the balloon is inflated to its said predetermined balloon diameter, and said balloon also exhibits a distended inflation diameter at which the balloon is stretched to a profile having a diameter that is in excess of said predetermined balloon diameter; and said balloon has a tensile strength greater than balloons that are made of materials other than nylon or polyamide materials and that have an inflated profile exhibiting a distended size - View Dependent Claims (16, 17, 18, 19, 20, 21)

22. A balloon for a medical device, comprising:
-
a nylon material or a polyamide material tubing that had been radially expanded to a predetermined balloon diameter; said balloon has a collapsed profile at which the outer diameter of the balloon approximates the outer diameter of said medical device, said balloon further having a non-distended inflation diameter at which the balloon is inflated to its said predetermined balloon diameter, and said balloon also exhibits a distended inflation diameter at which the balloon is stretched to a profile having a diameter that is in excess of said predetermined balloon diameter; and said balloon has a tensile strength greater than medical device balloons that are made of materials other than nylon or polyamide materials and that have an inflated profile exhibiting a distended size. - View Dependent Claims (23, 24, 25, 26, 27, 28)
