Extension guide catheter, and, uh, coronary treatment system.

摘要

An extension guide catheter (102) includes an impulse member (108) and a distal drive axis (110). The impulse member includes a segment that has a first surface (118) and a second surface (112) opposite the first surface. The segment includes aSulcus (128) on the first surface. The second surface is substantially flat. The distal drive axis is attached to the impulse member and includes a pass (132). The segment of the impulse member that includes the groove is adjacent to the distal drive axis.
