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.
