Abstract: An insertion catheter for a circulatory support catheter having a circulatory support device carried by an elongate flexible catheter shaft. The insertion catheter comprises a tubular body with a distal portion configured to axially movably receive the circulatory support device. A diameter of the distal portion is greater than a diameter of a mid portion of the tubular body. The insertion catheter may be inserted into an introducer sheath for delivery of the MCS device. A distal end of the insertion catheter may be located distally of a distal end of the introducer sheath and distally of the arterial bifurcation. The distal portion of the insertion catheter containing the MCS device may be located distally of the bifurcation, with a distal end of the MCS device slightly offset from the distal end of the tubular body.
