Minimally invasive delivery system for annuloplasty rings
First Claim
1. 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.

8. An annuloplasty or remodeling ring for treating an anatomical annulus comprising a plurality of substantially rigid curved segments that are coupled and adapted to define a circumferential plane, said coupled segments being configured to be placed at least partially circumferentially about the anatomical annulus to form a line to stabilize the anatomical annulus;
- and a plurality of segment-couplers for securely coupling two adjacent segments at about an outer comer of each segment, wherein said coupled segments are restricted to flex inwardly along said circumferential plane.

15. A method for percutaneously delivering an annuloplasty ring for treating an anatomical annulus, the annuloplasty ring comprising a plurality of substantially rigid curved segments that are coupled and adapted to define a circumferential plane, said coupled segments being configured to be placed at least partially circumferentially about the anatomical annulus to form a line to stabilize the anatomical annulus;
- and a plurality of segment-couplers for securely coupling two adjacent segments at about an outer comer of each segment, wherein said coupled segments are restricted to flex inwardly along said circumferential plane;
the method comprising steps of;
delivering said annuloplasty ring to the anatomical annulus percutaneously during a delivery phase;
deploying the annuloplasty ring during a deployment phase; and
placing and securing the annuloplasty ring at about the anatomical annulus. - View Dependent Claims (16, 17, 18, 19, 20)
