Minimally invasive delivery system for annuloplasty rings

摘要

A delivery system for delivering an annuloplasty ring through a percutaneous intercostal penetration of a patient's chest comprising an elongated handle having a distal end, a distal opening, and a lumen; a ring holder placed within the lumen of the elongated handle and configured to be releasably coupled to the annuloplasty ring, wherein the annuloplasty ring is retractable to a low tubular-profile suitable for being releasably coupled to the ring holder adapted for being placed within said lumen of the handle; and a deployment mechanism coupled to the ring holder and located on the elongated handle, said deployment mechanism being configured for deploying the ring holder out of said distal opening of the handle and for recessing the ring holder within said lumen.
