Abstract
A soft tip guiding catheter for atraumatic insertion into delicate, tortuous coronary vessels and introduction of an angioplasty balloon catheter therethrough. The guiding catheter includes a main tubular portion and a soft tubular tip with cooperating bonding surfaces for increasing the contact area and strength of the thermal bond therebetween. The cooperating bonding surfaces each include a proximal ground taper portion with a braid material included therein and a distal longitudinal portion without the braiding material. The main portion preferably includes an inner layer of lubricous material, an outer layer of a polyether block amide, and a reinforcing braid positioned therebetween. The main tubular portion also includes distal and proximal segments heat shrink bonded together to provide changes in durometer along the length of the catheter. The layers of the main portion provide a thin catheter wall with pushability, torquability, and kink resistance.
