Abstract

A textile-reinforced medical dilation balloon is provided, including a woven tubular textile sleeve with substantially longitudinal thermoplastic warp threads and at least one weft thread woven substantially perpendicular relative to the warp threads, where the sleeve defines a sleeve lumen. A medical dilation balloon is disposed within the sleeve lumen, and an adhesive coating substantially covers the inner and outer surfaces of the sleeve, attaching it to the balloon.

First claim

I claim:

1. A textile-reinforced medical dilation balloon, comprising:
a seamlessly woven tubular textile sleeve including substantially longitudinal warp threads that are substantially parallel to a central longitudinal axis of the sleeve and at least one weft thread having a high modulus, high tensile strength yarn, the at least one weft thread woven helically along a winding pitch that is substantially perpendicular relative to the warp threads without crossing over itself nor crossing over any other at least one weft thread between a proximal neck portion and a distal neck portion, wherein the sleeve defines a sleeve lumen; and
a medical dilation balloon disposed within the sleeve lumen.

2. The balloon of claim 1 , wherein the at least one weft thread comprises polyethylene.

3. The balloon of claim 1 , wherein the warp threads include at least one thermoplastic material.

4. The balloon of claim 1 , where the warp threads comprise a combination of polyester threads and polyethylene threads.

5. The balloon of claim 1 , where the at least one weft thread has a composition different from at least one of the warp threads.

6. The balloon of claim 1 , where the warp threads comprise polyethylene.

7. The balloon of claim 1 , where the warp threads comprise polyester.

8. The balloon of claim 1 , further comprising an adhesive coating substantially covering inner and outer surfaces of the sleeve and attaching it to the balloon.

9. The balloon of claim 8 , where the adhesive coating comprises urethane or acrylic.

10. The balloon of claim 1 , where the tubular textile sleeve includes a generally cylindrical central body portion and tapered end portions.

11. The balloon of claim 1 , comprising a rated burst pressure of at least 30 atm.

12. The balloon of claim 1 , comprising a rated burst pressure of at least 35 atm.

13. The balloon of claim 1 , where a warp thread count and a weft thread count each is about 50 to about 250 threads per inch.

14. The balloon of claim 1 , where a warp thread count is about 175 to about 200 threads per inch.

15. The balloon of claim 1 , where a weft thread count is about 125 to about 150 threads per inch.

16. The balloon of claim 1 , where a warp thread count is 175 threads per inch, and a weft thread count is 150 threads per inch.

17. A method of making a textile-reinforced medical dilation balloon device according to claim 1 , said method comprising steps of:
constructing the seamless woven tubular textile sleeve including substantially longitudinal warp threads that are substantially parallel to a central longitudinal axis of the sleeve and at least one weft thread woven helically along a winding pitch that is substantially perpendicular relative to the warp threads without crossing over itself nor crossing over any other weft thread between a proximal neck portion and a distal neck portion, so that the sleeve defines a sleeve lumen;
directing the medical dilation balloon, disposed on an inflation catheter, into the sleeve lumen; and
heating a portion of the balloon and or of the sleeve sufficiently to thermally bond the sleeve to the inflation catheter.

18. The method of claim 17 , where the at least one weft thread comprises a high-modulus, high-tensile-strength polyethylene yarn and the warp threads comprise polyester.

19. The method of claim 17 , where the at least one weft thread has a composition different from at least one of the warp threads.

20. The method of claim 17 , where the medical dilation balloon is oversized relative to the sleeve lumen by at least about 1 percent in at least one dimension.

21. The method of claim 17 , where an outer diameter of the medical dilation balloon is at least 5 percent oversized greater than an inner diameter of the sleeve lumen.

22. The method of claim 17 , where a warp thread count, a weft thread count, or both, each is about 50 to about 250 threads per inch.
