The present invention provides methods and devices (100) for grasping (106), and optional repositioning and fixation of the valve leaflets (LF) to treat cardiac valve regurgitation, particularly mitral valve regurgitation. Such grasping will typically be atraumatic providing a number of benefits. For example, atraumatic grasping may allow repositioning of the devices relative to the leaflets and repositioning of the leaflets themselves without damage to the leaflets. However, in some cases it may be necessary or desired to include grasping which pierces or otherwise permanently affects the leaflets. In some of these cases, the grasping step includes fixation (115).
La présente invention concerne des procédés et des dispositifs qui permettent d'agripper, et de remettre en place et fixer facultativement des feuillets valvulaires afin de traiter une regurgitation valvulaire, notamment une regurgitation valvulaire mitrale. Un tel agrippement est généralement atraumatique et offre certains avantages. Par exemple, un agrippement atraumatique permet de replacer les dispositifs relativement aux feuillets et de replacer les feuillets eux-mêmes sans les endommager. Toutefois, dans quelques cas, il peut être nécessaire ou souhaitable d'inclure un agrippement qui perce ou autrement affecte de façon permanente les feuillets. Dans certains de ces cas, l'étape d'agrippement s'accompagne de fixation.
