A catheter including a body for insertion into a blood vessel of a medical patient. The body including an interface thereon which is the portion of the body that is inserted into and in contact with the skin or blood vessel of the patient. The interface includes texture on its exterior surface such that when the catheter body is inserted into the blood vessel, the texture secures the catheter body from migration at the point of entry of the catheter body into the patient. The texture is obtained by scoring or molding an irregular surface along the length of the interface. In the event that the catheter is configured for use with an introducer or cannula, portions of the introducer or cannula may also be textured in accordance with the invention.

L'invention concerne un cathéter comprenant un corps destiné à être introduit dans un vaisseau sanguin de patient. Le corps comporte une interface, qui est la partie de ce corps introduite dans la peau ou le vaisseau sanguin et en contact avec la peau ou le vaisseau sanguin. La surface externe de l'interface comprend une texture qui, au point d'entrée dans le vaisseau sanguin, empêche le corps du cathéter de se déplacer vers l'intérieur, après l'insertion. Cette texture résulte de la formation d'une surface irrégulière obtenue par entaille ou moulage sur la longueur de la surface. Si le cathéter est destiné à être utilisé avec un introducteur ou une canule, on peut également réaliser la texture considérée sur des parties de l'introducteur ou de la canule.
