A catheter assembly comprises a catheter shaft having a proximal region a distal region and a rotational seal therebetween. The rotational seal comprises a first component fixedly engaged to the proximal region and a second component fixedly engaged to the distal region. The components engaged in an overlapping arrangement. The rotational seal is actuatable between a non- activated and activated states. In the non-activated state the first component and the second component are separated by a gap which provides for the distal region of the catheter shaft to be rotatable relative to the proximal region. In the activated state at least a portion of the fist component and the second component being sealingly engaged together such that distal region is made static relative to the proximal region.

L'invention concerne un ensemble cathéter qui comprend une tige de cathéter munie d'une région proximale, d'une région distale et d'un joint rotatif situé entre ces deux régions. Le joint rotatif comprend un premier composant en prise fixe avec la région proximale et un second composant en prise fixe avec la région distale. Les composants sont en prise dans une configuration de chevauchement. Le joint rotatif peut basculer entre un état non activé et un état activé. Dans l'état non activé, le premier composant et le second composant sont séparés par un espace qui permet à la région distale de la tige de cathéter de tourner par rapport à la région proximale. Dans l'état activé, au moins une partie du premier composant et du second composant viennent en prise étanche l'un avec l'autre de sorte que la région distale est statique par rapport à la région proximale.
