摘要： A catheter comprising an elongated catheter body having a lumen with a distal opening, an elongated inner tube having a flexible distal end portion and a flexible everting element coupled to the catheter body and the inner tube so that the everting element can be inverted and everted to the distal opening. The inner tube has an inner tube lumen which extends through the distal end portion of the inner tube. The distal end portion of the inner tube includes a flexible tubular layer and a flexible reinforcing layer which reinforces the tubular layer and inhibits radial collapse of the inner tube lumen in the distal end portion of the inner tube.
