Abstract
In some examples, a catheter (e.g., a balloon catheter) includes a guidewire tube extending through a catheter body and a coating on at least a portion of an outer surface of the guidewire tube. In some examples, the coating is an elastomeric coating. The coating is configured to increase friction between the portion of the outer surface of the guidewire tube and an inner surface of the catheter body when the portion of the outer surface contacts an inner surface of the catheter body.
