1. A device for endovascular vein puncture, comprising:
an elongate catheter extending along a longitudinal catheter axis and having a catheter proximal portion and a catheter distal portion;
a needle guide having a blunt needle guide distal end, wherein the needle guide is deployable from the catheter from a needle guide storage position to a needle guide working position, wherein in the needle guide working position, the needle guide distal end is radially spaced from the catheter, and in the needle guide storage position, the needle guide distal end is withdrawn towards the catheter relative to the needle guide working position;
a needle having a sharp puncturing end, wherein the needle is deployable from within the needle guide from a needle storage position to a puncturing position, wherein in the needle storage position, the sharp puncturing end is shy of the needle guide distal end, and in the puncturing position, the sharp puncturing end extends proud of the needle guide distal end; and
an ablation energy delivery device deployable from within the needle from an ablation energy delivery device storage position to an ablation energy delivery device treatment position, wherein the ablation energy delivery device has a blunt delivery device distal end,
wherein when in the needle guide working position, the puncturing position, and the ablation energy delivery device treatment position, the needle guide, the needle, and the ablation energy delivery device, respectively, are co-axial, and
wherein when in the ablation energy delivery device treatment position, the ablation energy delivery device has a straight configuration where it extends from the needle.
