    • A steerable endoluminal device adapted for delivery into a patient's vasculature. The device includes a tubular member having a distal deflection portion that extends to the distal end and a main body portion that extends from the deflectable portion to the proximal end, the tubular member further including a stiff portion extending along the distal deflection portion, and being formed of polymeric material, which is disposed circumferentially adjacent to the stiff portion. The stiff portion is made of a material that has an elastic modulus greater than the elastic modulus of the polymeric material. A pull wire extends between the proximal end and the distal end of the tubular member and is attached to the distal deflection portion to control deflection of the distal deflection portion of the tubular member.
    • 适于输送到病人脉管系统中的可操纵的腔内装置。 所述装置包括管状构件,所述管状构件具有延伸到所述远端的远端偏转部分和从所述可偏转部分延伸到所述近端的主体部分,所述管状构件还包括沿着所述远侧偏转部分延伸的刚性部分, 由聚合物材料形成,其周向地邻近刚性部分设置。 刚性部分由具有大于聚合物材料的弹性模量的弹性模量的材料制成。 拉线在管状构件的近端和远端之间延伸并且附接到远侧偏转部分以控制管状构件的远端偏转部分的偏转。
