1. A sheath assembly for insertion of a cord-shaped element into a body of a patient, said assembly comprising:
an introducer sheath having a proximal end and a distal end, the distal end configured to be inserted into the body of a patient while the proximal end protrudes from the body of the patient during insertion of the distal end of said assembly into the body of the patient;
an auxiliary sheath configured for insertion into the introducer sheath together with the cord-shaped element, the auxiliary sheath having a first fastener configured to detachably fasten the auxiliary sheath to the introducer sheath, and second fastener configured to detachably fasten the cord-shaped element to the auxiliary sheath;
wherein the introducer sheath has a first sheath housing, the first sheath housing having therein a first sheath inner chamber, the first sheath inner chamber having a first receiving channel for a cord-shaped element, a distal tubular section that terminates in the first sheath housing, and a first flushing device for flushing the first sheath inner chamber;
wherein the auxiliary sheath has a second sheath inner chamber having a second receiving channel for a cord-shaped element, a distal tubular part and a second flushing device for the second sheath inner chamber; and
wherein the first sheath housing is configured to position the distal end of the tubular part of the auxiliary sheath in the first sheath housing, proximally in front of the proximal end of the tubular section, wherein the second flushing device is connected to the first flushing device to allow an exchange of flushing fluid.
