A cannula and a method of inserting the cannula into a bone within a patient. The cannula comprises a distal section, a proximal section, and an intermediate section positioned therebetween. The distal section has a smaller diameter than the proximal section. The smaller diameter assists in inserting the distal section into the bone. The increased diameter of the proximal section gives rigidity and strength to prevent bending or flexing during insertion. The proximal section has a wall thickness greater than the distal section to give rigidity and strength to the cannula.
L'invention a trait à un cathéter et à un procédé d'insertion dudit cathéter dans l'os d'un patient. Le cathéter comprend une section distale, une section proximale, et une section intermédiaire placée entre ces dernières. Le diamètre de la section distale est inférieur à celui de la section proximale. Le diamètre le plus petit facilite l'insertion de la section distale dans l'os. Le diamètre de la section proximale, plus important, confère rigidité et résistance au cathéter, de manière à éviter toute courbure ou flexion de ce dernier lors de son insertion. La paroi de la section proximale est plus épaisse que celle de la section distale, ce qui confère rigidité et solidité au cathéter.
