摘要：
A catheter assembly comprises a first elongate tubular member having a proximal end portion defining a proximal end, a distal end portion having an opening therein and defining a distal end, and at least one lumen defined between the proximal end and the distal end. A second elongate tubular member has a proximal end portion defining a proximal end, a distal end portion defining a distal end, and at least one lumen defined between the proximal end and the distal end. The second elongate tubular member is received within the at least one lumen of the first elongate tubular member, such that the distal end portion of the second elongate tubular member projects from the opening in the distal end portion of the first elongate tubular member. An elongate, shape-imparting element is receivable in the at least one lumen of at least one of the first elongate tubular member and the second elongate tubular member. The shape-imparting element imparts a non-rectilinear shape to the distal end portion, of at least one of the first elongate tubular member and the second elongate tubular member.
