An intravascular catheter (10) including a proximal stiff metallic tube and a distal flexible tube. A distal portion of the metallic tube has a portion removed to define a void (22) (e.g., spiral slot) which decreases the stiffness of the metallic tube. A proximal portion of the distal flexible tube is disposed in the void to provide a secure connection and to blend the stiffness of the metallic proximal tube and the flexible distal tube without significantly increasing profile.
L'invention concerne un cathéter (10) intravasculaire comportant un tube métallique rigide proximal et un tube flexible distal. Une portion distale du tube métallique a une partie enlevée pour former un interstice (22) (par ex., une fente en spirale), lequel diminue la rigidité du tube métallique. Une portion proximale du tube flexible distal est placée dans l'interstice pour constituer un raccordement sûr et pour harmoniser la rigidité du tube métallique proximal à celle du tube flexible distal, sans en augmenter le profilé de manière sensible.
