A surgical capture component for deployment from a distal end of a catheter formed of a plurality of radially positionable shaped members each having a deployed position biased to radially position around a center axis and having a collapsed position adjacent to a loop a planar loop portion. The loop may be electrified to cauterize tissue. Deployment of the shaped members is provided by mechanical release or automatic release of a restraint when the loop is electrified.

L'invention porte sur un composant de capture chirurgical pour un déploiement d'une extrémité distale d'un cathéter formé d'une pluralité d'éléments dimensionnés de façon radialement positionnable, ayant chacun une position déployée sollicitée pour se positionner radialement autour d'un axe central et ayant une position pliée adjacente à une boucle ou partie de boucle plane. On peut faire passer un courant dans la boucle pour cautériser un tissu. Le déploiement des éléments dimensionnés est fourni par une libération mécanique ou une libération automatique d'une contrainte lorsque l'on fait passer un courant dans la boucle.
