Research Abstract

We developed a catheter therapy for ventricular septum perforation (VSP) by using a stent-graft placed in the left ventricle. we adapt a net type stent which is knitted by a Nytinol thread. As an initial model, we made a cone-shaped stent-graft but it did not fit with papillary muscles. We changed the design of the stent-graft as a dissymmetry. It covered only with the septum but a pressure power of the septum side particularly the septum base side was weak even with the improved model.We made delivery sheath for direct insertion via the apex and developed an insertion method by using peal off system. We insert a stent-graft into a rubber heart model by using this delivery system. The stent graft can be inserted via the left ventricle apex and has it as a design preserving the directionality by fixing it in the apex. The design decision of the stent-graft which does not affect cardiac function is difficult and remains in the completion of a trial
