A catheter (10) enabling a reduced puncture hole size into the skin (20) and blood vessel (22) is disclosed. In one embodiment, the catheter (10) has an elongate body (12) having an expandable sheath (18) extending at least a portion of its length. A pressure constraining sheath (18) is positioned to surround the expandable sheath (18), at a selected region to prevent expansion of the inner sheath (18) at the region of the constraining sheath (16). In one preferred use, the constraining sheath (16) is positioned at the puncture hole. During use, the catheter (10) increases in cross-section by the expandable sheath (18) expanding from a first diameter to a second diameter. However, the outer sheath (16) does not expand, maintaining a small diameter at the puncture site.

La présente invention concerne un cathéter permettant de réaliser un orifice d'insertion réduite dans la peau et les vaisseaux sanguins. Dans un mode de réalisation, le cathéter présente un corps allongé ayant une gaine expansible s'étendant au moins sur une portion de sa longueur. Une gaine de contrainte en pression est positionnée afin d'enserrer la gaine expansible, au niveau d'une région choisie pour empêcher la dilatation de la gaine intérieure au niveau de la région de la gaine de contrainte. Dans un mode d'utilisation préféré, la gaine de contrainte est positionnée au niveau de l'orifice d'insertion. Lors de son utilisation, la section transversale du cathéter s'accroît au moyen d'une gaine expansible se dilatant à partir d'un premier diamètre pour atteindre un deuxième diamètre. Cependant, la gaine extérieure ne se dilate pas, préservant un petit diamètre au niveau de l'orifice d'insertion.
