Abstract
A method of manufacturing a balloon catheter involves applying a first application liquid, which contains a hydrophilic coating material, to the outer periphery of a balloon which is disposed on an elongated catheter and is held in an expanded state; folding the balloon; and applying a second application liquid, which contains the hydrophilic coating material, to the balloon with the balloon folded.
Claims17
A method of manufacturing a balloon catheter comprising:
- applying a first application liquid, which contains a hydrophilic coating material, to an outer periphery of a balloon which is disposed on a catheter, the first application liquid being applied while the balloon is in an expanded state;
- folding the balloon;
- and
- applying a second application liquid, which contains a hydrophilic coating material, to the balloon while the balloon is folded.
1 more element
A balloon catheter comprising:
- a catheter that includes a catheter body connectable to a catheter hub:
- a balloon disposed on the catheter body, the balloon being contracted and wrapped around the catheter body so that the balloon is folded, with parts of the balloon folded to inside, the folded balloon possessing an outer surface;
- a lumen in the catheter in fluid communication with an interior of the balloon to introduce the balloon expanding fluid into the balloon;
- a first hydrophilic coating layer on an outer surface of the balloon, the first hydrophilic coating layer existing on the outer surface including the outer surface of the parts of the balloon folded to the inside;
- and
- a second hydrophilic coating layer continuously surrounding an outer periphery of the folded balloon including portions of the outer periphery of the balloon at which the first hydrophilic coating layer exists.
3 more elements
A balloon catheter comprising:
- a catheter;
- a balloon disposed on the catheter and folded on the catheter so that the balloon is wrapped around the catheter;
- a first hydrophilic coating layer on an outer surface of the balloon;
- a second hydrophilic coating layer surrounding an outer the periphery of the balloon in the state of being folded in such a manner as to be wrapped around the catheter.
