摘要：
A catheter assembly (100) includes an inner liner (10) made of flexible materialand an outer layer (60) having a steering mechanism. The steering mechanism includesat least one flat wire and a corresponding lumen (42) through which the flat wiremay travel. The steering mechanism may also include at least one pull ring to whichthe flat wires are attached. A layer of heat shrink (70) material may encompassthe outer layer. A braided wire assembly (50), which may have a braid density thatvaries along the length of the catheter, may also be provided in the outer layer.The overall cross-section of the catheter assembly is preferably substantiallycircular. A catheter shaft (100) may include a plurality of segments (61, 62)of differing hardness characteristics. The outer layer typically comprisesa melt processing polymer such that the catheter assembly may be laminated usingheat.
