Abstract
An intravascular catheter system, such as a dilatation catheter system for angioplasty procedures, which provides for the replacement of the catheter or the guidewire thereof during the procedure. The intravascular catheter has an guidewire-receiving inner lumen extending along the length thereof. A first guidewire port is provided in the catheter body at or near the proximal end of the catheter, a second guidewire port is provided in the catheter body at a location spaced distally from the first guidewire port and proximally from a diagnostic or therapeutic means on a distal portion of the catheter and a third guidewire port is provided in the distal end of the catheter. The guidewire ports are in communication with the guidewire-receiving inner lumen.
Claims1
An adapter for mounting on an proximal end of an intravascular catheter having an inner inflation lumen and an inner guidewire receiving lumen, the adapter comprising:
- a) a first inner lumen adapted to be in fluid communication with the inner inflation lumen of the catheter;
- and
- b) a second inner lumen defined by a generally tubular wall, bounded by proximal and distal openings, and adapted to be in fluid communication with the inner guidewire receiving lumen of the catheter, the wall being adapted to form a slit from said proximal opening to said distal opening to allow a guidewire to exit laterally from the inner guidewire receiving lumen through said slit in the adapter wall.
