[Development of a J-shaped sheath and its usefulness for angiography].

We developed a new sheath for selective trans-brachial and trans-femoral arteriography. This sheath has a J-shaped tip and can be inserted by the conventional Seldinger method using a linear dilator. This sheath was particularly useful for abdominal angiography via the brachial artery and pelvic arteriography via the femoral artery.
