| 摘要 |
<p>The present invention relates to a catheter system comprising: an elongated tubular member (111) with a plurality of lumens and electrical conductors threaded therethrough from proximal to distal extremity. The lumens are either inflation lumens or great lumens allowing other catheters moving slidably thereon; a head portion which has one or a plurality of arms (112, 113) having proximal and distal extremities. The proximal extremity of the arms are connected to the distal extremity of the elongated member. There are a plurality of longitudinally spaced-apart electrodes (115, 117) provided on each arm and connected to conductors of the elongated member. The head portion undergoes an expanded and a contracted position by an expanding system (114); a stabilising system (116) bonded to the head portion having a contracted and expanded position. In expanded position, this system applies firmly the working head to the cardiac wall under investigation.</p> |
