The "probe" balloon-on-a-wire device is an excellent balloon catheter for traversing very tight stenoses. Extending the probe by transecting its proximal inflation hub and then linking it to an extension wire has further enhanced its utility, as a wire exchange can then be performed without loosing wire access across a dilated lesion. We now report a previously undescribed technique for reconstituting and reusing an extended probe. The probe is initially transected at its proximal end. It is then extended by connecting a "Linx" wire into the open central lumen of the probe's hypotube. An over-the-wire balloon dilatation system is then substituted, via a wire exchange using a probing catheter, for final definitive dilatation. The probe is then reconstituted in the following manner. The inflation hub of the probe is recreated by modifying a standard USCI Tuohy-Borst Y adaptor and attaching this to the transected probe hypotube. It is subsequently used for dilating other stenotic arteries during multivessel angioplasty. The utility of this method was demonstrated in 5 consecutive cases. All cases underwent successful dilatations. There were no complications. This initial experience would suggest that the probe can be reused quite safely and effectively.
“探头” 导丝球囊装置是一种用于穿过非常狭窄狭窄段的出色球囊导管。通过横断其近端充盈接头并将其连接到延长导丝来延长探头，进一步增强了其效用，因为这样就可以在不失去穿过扩张病变的导丝通路的情况下进行导丝交换。我们现在报告一种以前未描述的重建和重复使用延长探头的技术。探头首先在其近端横断。然后通过将一根 “林克斯” 导丝连接到探头海波管开放的中心腔中来延长它。然后通过使用探查导管进行导丝交换，用球囊扩张系统替换探头，进行最终的确定性扩张。然后按以下方式重建探头。通过修改标准的美国外科器械公司（USCI） Tuohy-Borst Y 形适配器并将其连接到横断的探头海波管上，重新制作探头的充盈接头。随后它被用于在多支血管成形术中扩张其他狭窄动脉。该方法的效用在连续5例病例中得到了证实。所有病例均成功进行了扩张。无并发症发生。这一初步经验表明，探头可以非常安全有效地重复使用。
