消融导管
摘要：
一种消融导管包括一个控制手柄，和能够可移除地连接至该控制手柄上的一个导管鞘，该导管鞘限定了一个流体腔并且具有接近该导管鞘的远端的多个穿孔。该消融导管进一步包括一个形状赋予元件，该形状赋予元件被插入该导管鞘的流体腔中，并且能够可移除地连接至该控制手柄上。该形状赋予元件可连接至一个RF能量源，这样使得在使用中，该形状赋予元件充当一个电极，该电极对流入该流体腔中有待通过该导管鞘上的该多个穿孔排出的流体进行充电。
摘要（英）：

An ablation catheter includes a control handle, and a catheter sheath removably connectable to the control handle, the catheter sheath defining a fluid lumen and having a plurality of perforations proximal the distal end of the catheter sheath. The ablation catheter further includes a shape imparting element inserted into the fluid lumen of the catheter sheath and removably connectable to the control handle. The shape imparting element is connectable to an RF energy source so that, in use, the shape imparting elements acts as an electrode charging fluid into the fluid lumen to be expelled through the plurality of perforations on the catheter sheath.
