Direxion™可控微导管主要尺寸

小腔	大腔
紫色接口（Hub）） 0.021“内径远端尖端外径 2.4 F 近端最大外径OD 3F 0.035“ 导丝兼容性	黄色接口（Hub） 0.027“内径远端尖端外径 2.8 F 近端最大外径3F 0.038“导丝兼容性

Unique Tip Shapes for Increased Control

• Typically the shaft is braided

– Tungsten spiral

– Stainless steel spiral

– Nitinol slotted tube

– Fiber braiding

• Catheter has different zones

– stiffer near the hub for a good pushability,

– flexible at the distal end

可控NITINOL [ˈnitinɔl] 微导管

近端：刻槽切口间距大。较高的刚性，更好的推进性

远端:刻槽切口间距小。较柔软的尖端，更好的控制

* All Flow Rates are per manufacturers DFU at the maximum burst pressure for each device and 130 cm or 135 cm catheter length with 100% contrast

2) Very Pushable/Trackable

3) Steerable

Direxion™ Flow Rates

Slotted [ˈslɒtɪd] nitinol hypotube combined with a braided liner allows Direxion to have 19% better flow rates than other similar ID microcatheters*
Direxion HI-FLO has 30% better flow rates than similar-sized microcatheters*

* All Flow Rates are per manufacturers DFU at the maximum burst pressure for each device and 130 cm or 135 cm catheter length with 100% contrast

不完全栓塞时无需再导管，微导管可以造影，避免撤管
