    • An agent delivery catheter which has a support member comprising at least one articulating arm having an end fixedly secured relative to the shaft and having an anchor end section opposite to the fixed end. The articulating arm is biased to pivot at the fixed end away from the shaft, to transform from a low profile configuration to a high profile configuration in which the arm extends laterally away from the shaft and the anchor end section contacts the patient's body lumen wall, to support the shaft in the body lumen during delivery of an agent, for example by injection from a needle extended from the catheter into the wall of the body lumen.
    • 一种药剂输送导管,其具有支撑构件,所述支撑构件包括至少一个铰接臂,所述至少一个铰接臂具有相对于所述轴固定的端部,并且具有与所述固定端相对的锚定端部。 铰接臂被偏压以在远离轴的固定端枢转,从低轮廓构型转变成高轮廓构型,其中臂从轴向横向延伸远离轴并且锚固端部接触病人的体腔壁, 以在药剂递送期间例如通过从从导管伸出的针头注射到体腔的壁中来支撑身体腔中的轴。
