Abstract

Cette invention se rapporte à un dispositif d'élimination de caillots et de tout corps étranger, qui comprend un cathéter ayant au moins une lumière. Dans le cathéter est disposé un serpentin de capture de caillots qui est relié à un mandrin d'insertion. Dans un premier mode de réalisation, le serpentin de capture de caillots est fabriqué à partir d'un matériau élastique ou superélastique solide à mémoire de forme, de préférence le nitinol. Grâce à son élasticité ou superélasticité, le serpentin peut se déformer à l'intérieur du cathéter et reprendre ensuite sa configuration d'origine, lorsqu'il est sorti de la lumière du cathéter. Dans un second mode de réalisation, le serpentin est un serpentin à deux phases qui change de forme lorsqu'il est chauffé ou lorsqu'il est traversé par un courant électrique. Une fois établie la configuration du serpentin, celui-ci peut être utilisé pour prendre au piège et extraire à la façon d'un tire-bouchon le caillot hors d'un vaisseau sanguin. On extrait un caillot du vaisseau sanguin en déplaçant le serpentin de capture de caillots et le cathéter dans une direction proximale, jusqu'à ce que le caillot puisse être retiré ou acheminé dans un autre vaisseau qui ne débouche pas dans un organe critique. On capture de la même manière tout corps étranger en déployant le serpentin de façon distale par rapport au corps étranger à extraire et en déplaçant le serpentin de capture de caillots dans une direction proximale, jusqu'à ce que le corps étranger soit piégé à l'intérieur du serpentin. En retirant le dispositif du corps du patient, on retire également le corps étranger.
