Percutaneous excimer laser angioplasty is dependent on a reliable and effective energy transmission through fiberoptic devices. Compared with bare fibers, ring catheters provide improved flexibility and a central channel for insertion of guide wires. Peripheral laser catheters (7-9 F) were used in 32 patients with arterial occlusive disease in the lower limbs. The technical success rate was 91%. Vessel wall dissections occurred in nine cases but caused no clinical sequelae in the preliminary follow-up period (1-6 months). The clinical application of the catheter devices proved to be safe.
经皮准分子激光血管成形术依赖于通过光纤设备进行可靠且有效的能量传输。与裸光纤相比，环形导管具有更好的柔韧性以及用于插入导丝的中央通道。32例下肢动脉闭塞性疾病患者使用了外周激光导管（7-9F）。技术成功率为91%。9例发生血管壁夹层，但在初步随访期（1-6个月）未引起临床后遗症。导管装置的临床应用证明是安全的。
