Patent

CA 2305530

This invention is a method, a device for introduction of a catheter (6C), and/or delivering a fluid, such as oxygenated blood, to a patient's vascular system including a cannula (2C) having an expandable portion (4C). The expandable portion (4C) is movable from a collapsed position to an expanded position. The expandable portion (4C) is inserted into the patient in the collapsed position which facilitates introduction and advancement of the cannula (2C) through the patient's blood vessel. After introduction into the patient, the expandable portion (4C) is moved to the expanded position. The expandable portion (4C) protects the blood vessel against fluid forces when flowing a fluid through the cannula (2C), and protects the vessel from contact with the catheter (6C) advanced through the cannula (2C).

L'invention concerne un procédé et un dispositif permettant d'introduire un cathéter (6C), et/ou d'administrer un fluide, par exemple du sang oxygéné, dans le système vasculaire d'un patient. Ce cathéter est constitué d'une canule (2C) comprenant une partie extensible (4C), cette partie extensible (4C) pouvant passer d'une position de repli à une position d'extension. Cette partie extensible (4C) est inséré à l'intérieur dudit patient dans sa position de repli, ce qui facilite son introduction, la canule (2C) pouvant ainsi progresser à l'intérieur du vaisseau sanguin de ce patient. Après avoir été introduite dans le patient, cette partie extensible (4C) passe dans sa position d'extension. Cette partie extensible (4C) peut ainsi protéger le vaisseau sanguin contre les forces exercées par un fluide qui s'écoule dans ladite canule (2C), et prévenir tout contact entre ce vaisseau et ledit cathéter (6C), au fur et à mesure que ce dernier progresse à l'intérieur de la canule (2C).
