Abstract
The present invention generally relates to the field of intravascular medical devices, and more specifically to the field of balloon catheters and other similar diagnostic or therapeutic catheters within the body for treatment and diagnosis of diseases. In particular, the present invention relates to reinforced balloon catheters and drug-eluting balloon catheters and corresponding methods for producing same.
Claims52
A balloon catheter device, comprising:
- an inflatable balloon comprising a wall with an inner surface that defines an inner volume;
- an elongate member having an outer surface, the elongate member being disposed within the inner volume of the inflatable balloon such that a lumen is established between the inner surface of the balloon and the outer surface of the elongate member when the balloon is in a non-collapsed state;
- and
- a plurality of structural members traversing portions of said lumen.
1 more element
A therapeutic medical article comprising:
- an inflatable balloon having a an inner surface that defines a inner volume;
- an elongate member having an outer surface, the elongate member being disposed within the inner volume of the inflatable balloon such that a lumen is established between the inner surface of the balloon and the outer surface of the elongate member when the balloon is in a non-collapsed state;
- and
- a plurality of flexible hollow members disposed in said lumen, each hollow member comprising an exterior surface and an interior cavity containing a therapeutic agent, wherein a portion of the exterior surface is attached to the inner surface of the balloon, and each hollow member having an associated channel that extends (a) from the outer surface of the balloon to the interior cavity of the hollow member or (b) from the outer surface of the balloon to a puncturing member, disposed between inner surface of the balloon and the exterior surface of the hollow member, which punctures the hollow member upon inflation of the balloon, such that the therapeutic agent contained in the interior cavity of the hollow member exits the device through the channel upon inflation of the balloon.
1 more element
A method of manufacturing a reinforced balloon comprising:
- providing an assembly that comprises (a) an elongate member having a plurality of strands attached its outer surface disposed within (b) an inner volume of a balloon having an adhesive material disposed on its inner surface such that a lumen is formed between the outer surface of the elongate member and the inner surface of the balloon when the balloon is in a non-collapsed state;
- and
- producing a force that urges at least some of said strands into contact with the adhesive material disposed on the inner surface of the balloon such that, upon cure of said adhesive material and upon inflation of the balloon, a plurality of strands traverse portions of the lumen between the elongate member and the balloon.
