Abstract
A soft tip angioplasty balloon catheter having mating internal and external tapers for banding the soft tip to the main portion of the catheter. The main portion includes a dual lumen tube and a single lumen tube extending from the distal end thereof. A circularly shaped passageway for insertion over a wire guide extends longitudinally through the entire main portion and soft tip of the catheter. A
second, crescent or quarter-moon shaped passageway extends through the dual lumen tube and communicates with the interior of an uninflated angioplasty balloon for the inflation thereof. The balloon is positioned and stored around the smaller diameter single lumen tube. The angioplasty balloon is attached about the distal end of the dual lumen tube and the proximal end of the soft tubular tip. The distal end of the balloon is positioned in an annular recess about the proximal end of the soft tip with an outside diameter that approximates the maximum outside diameter of the catheter about the main portion. Tungsten ring markets are positioned around the single lumen tube to indicate the position of the angioplasty balloon when in a coronary vessel. The distal end of the soft tip is also externally tapered to minimize trauma to a coronary vessel wall. The tubular tip comprises a material having a durometer softer than that of the main portion for further minimizing trauma to a coronary vessel wall.
