ABSTRACT:
A method of manufacturing a catheter includes providing an outer shaft having a lumen therethrough and at least one catheter component disposed at least partially within the lumen, placing an inner shaft within the lumen such that the at least one catheter component is located between the shafts, thereby forming a catheter assembly having an outer surface, and applying energy to the catheter assembly to melt at least the outer shaft to bond the outer shaft to the inner shaft. A unitary catheter shaft having the at least one catheter component substantially embedded therein results. The durometer of the outer shaft may differ from the durometer of the inner shaft, such that the catheter shaft varies radially in durometer. The durometer of the catheter shaft may also vary longitudinally. A shaping wire may be provided to form the distal end of the catheter shaft into a desired shape.
