Title: Coronary angioplasty using the probing catheter in combination with the Probe™ balloon wire
Abstract: The ProbeTM (USCI) “Balloon-on-a-WireTM” is a percutaneous transluminal coronary angioplasty (PTCA) catheter that offers extremely low deflated profiles1 to allow its passage through very high grade stenoses, thereby increasing primary success rates.2 However, some drawbacks have been reported, which are a consequence of the single lumen, fixed wire construction.2,3 The major shortcoming of the Probe may well be its inability to be exchanged over a wire for another catheter without having to recross the lesion. This frustrates the exchange for a larger balloon size if a dilatation has been inadequate. Furthermore, it eliminates the positioning of a “bailout” perfusion or infusion catheter3 in case of an acute occlusion after PTCA. Distal pressure measurements or contrast injections are impossible because of the lack of a distal port. Recently, the probing catheter (USCI) has been introduced. This device is a 4Fr sheath designed for use with the Probe (Figure 1). The combined use of the probing catheter and the Probe seems to be the solution to the aforementioned problems, and may in addition enhance the Probe's performance in terms of steerability, pushability and ability to cross subtotal or total occlusions.
