Insertion system for implants for treating bifurcated aneurysms

The invention relates to an insertion system for an implant (1) for influencing the blood flow in the region of an aneurysm (22) located at a vascular bifurcation. The implant (1) has two distal tubular implant parts (2) for placement in a blood vessel (21) branching from a trunk blood vessel (20) and connected to each other at a branching point (4). The insertion system has two cannulas (5), each of which is designed for holding a distal tubular implant part (2). The two cannulas (5) each have a distal cannulas portion (6), and the distal cannulas portions (6) each have an opening region (7) extending in the longitudinal direction. The distal cannula parts (6) each adjoin a proximal end part (8), by means of which the cannula (5) can be retracted in a proximal direction such that the opening region (7) opens, and the distal tubular implant parts (2) each pass through the opening region (7) and are released into the branch vessel (21). Alternatively, a single cannula having an open region for gradually releas
