Abstract

The present invention concerns an elongated medical device (1) suitable for intravascular insertion. Said device comprising a flexible elongated body (2) having a distal portion (3) with a distal end (4) and a proximal portion (5), and a mapping electrode assembly (80) located at the distal portion (3) having a plurality of electrodes (82), the electrode assembly (80) being configured to have an unexpanded condition (UC), where the electrode assembly (80) is stored at a portion of the elongated body (2), and to have an expanded condition (EC), where the electrode assembly (80) forms a at least two dimensional mapping screen that has a center of symmetry (C) and wherein a force sensor (20) is disposed within said flexible elongated body (2) proximate said distal end (4).
