“…Although the Biostar has reached the production step and have been demonstrated to be effective at least in simple anatomy but not in long‐tunnel PFO or large ASA, the latter techniques, probably suitable for long‐tunnel or hypertrophic rims, have been completely abandoned for the high rate of incomplete closure even in simple anatomies [18, 19]. Nowadays an increasing number of devices are becoming disposable on the market, but with some exceptions, such as the Premere Occlusion system or the Helix device, most used devices have a symmetrical opening philosophy and remain too rigid or too flexible to be properly adapted to long‐tunnel PFOs or hypertrophic rims.…”
