A medical retrieval device (10) is provided which includes an elongated cylindrical member (11) having a passage extending therein and having a metallic proximal (21) and distal (37) portions. The proximal and distal portions (21, 37) are formed as separate pieces and connected at a junction (59). The elongated cylindrical member (11) has an area of substantially constant inner and outer diameters extending at least from a portion of the proximal portion (21) closely adjacent to the junction (59) through the junction (59) and to a portion (37) of the distal portion closely adjacent to the junction (59). |
