New transluminal angioplasty catheters based upon the linear extrusion of the dilating element have been developed to facilitate placement of the dilating balloon within the arterial narrowing. In a multicenter study, the use of linear extrusion catheters has been shown to be safe and effective in adjunctive intraoperative peripheral dilatations. Physical measurements of the frictional forces exerted on the inner arterial surfaces during advancement of 3 angioplasty catheter designs show that the linear extrusion catheter consistently minimizes these forces. The use of a secondary guiding sheath in conjunction with a linear extrusion catheter provides additional directional capability. A secondary guiding sheath with a side port has recently been developed that allows access to difficult-to-cannulate vessels. The favorable results of the clinical studies and research data justify an ongoing evaluation of these concepts in percutaneous dilatation procedures and in intraoperative coronary procedures.
基于扩张元件的线性挤压技术开发的新型腔内血管成形术导管，已用于便利将扩张球囊放置在动脉狭窄部位。在一项多中心研究中，线性挤压导管在术中辅助外周扩张中已被证明是安全有效的。对三种血管成形术导管设计在推进过程中作用于动脉内表面的摩擦力进行的物理测量表明，线性挤压导管始终能将这些力降至最低。将辅助导鞘与线性挤压导管结合使用可提供额外的定向能力。最近已开发出一种带有侧孔的辅助导鞘，可用于进入难以插管的血管。临床研究和研究数据的良好结果证明，在经皮扩张手术和术中冠状动脉手术中对这些概念进行持续评估是合理的。
