Abstract
Disclosed is a medical catheter comprising a guidewire shaft defining a guidewire lumen. A distal tip extension defines a distal tip extension lumen having at a proximal end thereof a distal end of the guidewire shaft sealingly affixed therein. The inflatable balloon has a body portion, a tail portion and a cone shaped portion. The cone-shaped portion extends between the distal end of the body portion and the proximal end of the tail portion. The balloon tail portion is sealingly affixed to the distal tip extension such that the proximal end of the distal tip extension extends proximally from the proximal end of the balloon tail portion, the distal end of the distal tip extension extends distally from the distal end of the balloon tail and the distal end of the guidewire shaft is in alignment with the proximal end of the balloon tail portion.
