A transcatheter insertion system for the insertion of an intracorporeal device using an insertion device, comprising:
- an insertion device,
- an outer sheath arranged and configured to form a passageway for the intracorporeal device and/or the insertion device, and
- a guiding means for guiding the insertion device, wherein the guiding means is a substantially ring-shaped element having a doughnut shape, and wherein an outer diameter of the doughnut shape of the guiding means fits inside a diameter of the passageway formed by the outer sheath and said guiding means defines an opening which is narrower than a distal opening of the passageway formed by the outer sheath, wherein the guiding means is positioned adjacent to or at a distal end of the outer sheath,
- wherein the insertion device further comprises a guide wire and wherein the guide wire comprises an integrally formed puncture head, wherein the puncture head is formed at a distal end of the guide wire and comprises a tapered distal tip, such that the puncture head is configured to facilitate the puncture of an anatomical wall,
- wherein the insertion device comprises means for detachably connecting to the intracorporeal device, and
- wherein the means for detachably connecting to the intracorporeal device comprises one or more retractable tabs.
A transcatheter insertion system for the insertion of an intracorporeal device using an insertion device, comprising:

- wherein the guiding means comprises an inflatable balloon,
- wherein the insertion device further comprises a guide wire,
- wherein the guide wire comprises an integrally formed puncture head, and
- wherein the puncture head is formed at a distal end of the guide wire and comprises a tapered distal tip, such that the puncture head is configured to facilitate the puncture of an anatomical wall.
