The catheter (10) includes a handle (12), a catheter sheath that has at least one conductor within the lumen (14), and a stylet which is received in a catheter sheath (14). The catheter sheath (14), providing (40) a tubular member to form an opening in the wall of the tubular member distal end of the tubular member (30), inserting a conductor (26) within the lumen of the tubular member It is prepared by the. Attached to (28) electrodes, the electrodes (28), the distal end of the exposed (26) the conductor is attached to the outer surface of the tubular member (40) to cover the opening. The tubular member is treated by heat to seal (28) electrodes. [Selection Figure Figure 3カテーテル(10)は、ハンドル(12)と、内腔内に少なくとも1つの導体があるカテーテルシース(14)と、カテーテルシース(14)内に受け入れられるスタイレットとを備える。カテーテルシース(14)は、管状部材(40)を提供し、管状部材の遠位部(30)において管状部材の壁に開口部を形成し、管状部材の内腔内に導体(26)を挿入することによって製造される。導体(26)の露出した遠位端は電極(28)に取り付けられ、電極(28)は、開口部を覆うように管状部材(40)の外面に取り付けられる。そして、管状部材は電極(28)を封止するように熱によって処理される。【選択図】図3
