ABSTRACT:
A catheter, such as an angioplasty catheter is provided with a distal tip segment having a helical slit. The helical slit has a proximal end and a distal end that extends fully to and intersects the rim of the tip segment that defines the distal outlet orifice. The helically slit tip segment can be unrolled partly or fully from its helical configuration and may be attached directly to an indwelling guidewire at any location along the exposed length of the guidewire. The catheter includes a guidewire lumen thereby enabling the catheter to be placed on a guidewire in conventional or in monorail fashion. Additionally, when placed on a guidewire in monorail fashion, the guidewire lumen of the catheter may be used to infuse liquids, take pressure measurements or the like.
