CONTROL SYSTEM FOR SHAPABLE CATHETER

An intravascular device 10 includes an elongate body 12 having a proximal end and a distal end, and more than one energy transfer conduit 20 extending within the elongate body. The distal end of the energy transfer conduit terminates at different axial positions along the distal end of the elongate body. In one embodiment, the number of energy transfer conduits is only two, such that the number of bends in the composite curve presented by the distal end of the elongate body is only two, however, the number of energy transfer conduits may be any suitable number. 血管内装置10包括具有近端和远端的长型主体12，以及在长型主体内延伸的多于一个能量传输管道20。能量传输管道的远端沿长型主体的远端终止于不同轴向位置处。在一个实施例中，能量传输管道的数目只有两个，使得由长型主体的远端所呈现的复合曲线中的弯曲部的数目只有两个，然而能量传输管道的数目可以是任何合适的数目。
