Abstract
Medical devices and methods for making and using medical devices are disclosed. An example medical device may include a catheter. The catheter may include a catheter shaft and a balloon. The balloon may comprise a cone portion, a waist portion, and a body portion. A fiber braid may be disposed along the balloon. An inner surface of the waist portion may be thermally bonded to an outer surface of the catheter shaft and an inner surface of the fiber braid may be adhesively bonded to an outer surface of the waist portion.
Claims20
A method of making a catheter assembly, the method comprising:
- disposing a fiber braid about a balloon, the balloon comprising a cone portion, a waist portion and a body portion, an end of the fiber braid being terminated at a predetermined point relative to the waist portion;
- disposing the balloon on a catheter shaft;
- applying heat to at least a portion of the waist portion to thermally bond an inner surface of the waist portion to an outer surface of the catheter shaft;
- and
- after thermally bonding the waist portion and the catheter shaft, then applying adhesive to bond an inner surface of the fiber braid to the outer surface of the waist portion.
A method of making a catheter assembly, the method comprising:
- disposing a fiber braid about a balloon, the balloon comprising a body portion, a waist portion, and a cone portion disposed between the body portion and the waist portion, an end of the fiber braid being terminated at a predetermined point relative to the waist portion;
- disposing the balloon on a catheter shaft;
- retracting at least a section of the fiber braid toward the body portion to expose a section the waist portion;
- applying heat to at least the exposed section of the waist portion to create a thermal bond between an inner surface of the waist portion and an outer surface of the catheter shaft;
- and
- after creating the thermal bond, then moving the retracted section of the fiber braid back over the waist portion, and adhesively bonding an inner surface of the fiber braid to the outer surface of the waist portion.
A method of making a catheter assembly, the method comprising:
- disposing a fiber braid about a balloon, the balloon comprising a cone portion, a waist portion and a body portion, an end of the fiber braid being terminated and flared at a predetermined point relative to the waist portion;
- disposing the balloon on a catheter shaft;
- sliding a balloon protector distally over the waist portion of the balloon toward the body portion, exposing a section of the waist portion;
- applying a non-heat curing adhesive to a proximal region of the exposed section of the waist portion and allowing the adhesive to flow under the flared end of the fiber braid;
- sliding the balloon protector proximally over the waist portion to squeeze out excess adhesive;
- and
- curing the adhesive.
