A medical device comprising: an elongate member having a proximal portion and a shaft extending from the proximal portion, the proximal portion having a first outside diameter , the shaft having a first proximal end attached to the proximal portion and a first distal end , the shaft having a second outside diameter that is less than the first outside diameter of the proximal portion; an intermediate member releasably attached to the elongate member and releasably disposed on the shaft, the intermediate member having a second proximal end disposed between the first proximal end and the first distal end, a second distal end , a third outside diameter , and an intermediate member body defining an intermediate member lumen , the third outside diameter being greater than the first outside diameter of the proximal portion, the intermediate member lumen having a first inside diameter that is less than the first outside diameter of the proximal portion; and a sheath disposed on the shaft, the sheath having a fourth proximal end , a fourth distal end , and a sheath body defining a first sheath opening on the fourth proximal end of the sheath, a second sheath opening on the fourth distal end of the sheath, and a sheath lumen extending from the first sheath opening to the second sheath opening; a cap releasably attached to the intermediate member and releasably disposed on the shaft, the cap having a third proximal end, a third distal end, and a cap body defining a cap lumen; and said sheath partially disposed between the intermediate member and the cap, the first sheath opening having a second inside diameter that is greater than the first inside diameter of the intermediate member lumen. an elongate member having a proximal portion and a shaft extending from the proximal portion, the proximal portion having a first outside diameter , the shaft having a first proximal end attached to the proximal portion and a first distal end , the shaft having a second outside diameter that is less than the first outside diameter of the proximal portion; an intermediate member releasably attached to the elongate member and releasably disposed on the shaft, the intermediate member having a second proximal end disposed between the first proximal end and the first distal end, a second distal end , a third outside diameter , and an intermediate member body defining an intermediate member lumen , the third outside diameter being greater than the first outside diameter of the proximal portion, the intermediate member lumen having a first inside diameter that is less than the first outside diameter of the proximal portion; and a sheath disposed on the shaft, the sheath having a fourth proximal end , a fourth distal end , and a sheath body defining a first sheath opening on the fourth proximal end of the sheath, a second sheath opening on the fourth distal end of the sheath, and a sheath lumen extending from the first sheath opening to the second sheath opening; a cap releasably attached to the intermediate member and releasably disposed on the shaft, the cap having a third proximal end, a third distal end, and a cap body defining a cap lumen; and said sheath partially disposed between the intermediate member and the cap, the first sheath opening having a second inside diameter that is greater than the first inside diameter of the intermediate member lumen. <EOS>
