1. An implantable device for controlling at least one of a shape and size of an anatomical structure or lumen, comprising:
- an adjustable implantable device having an adjustable member configured to adjust the dimensions of the implantable device, the implantable device including an implant body;
an adjustment tool configured to be removeably coupled to the adjustable member to actuate the adjustable member and provide for adjustment before, during or after the anatomical structure or lumen resumes normal physiologic function;
an elongated track member arranged extending through an interior of the implant body or arranged encircling an exterior of the implant body; and
a coil configured to fasten the implantable device to tissue around the anatomic structure or lumen, wherein the coil is provided in a spiral path arranged encircling the track member and having a portion adapted to extend into the tissue adjacent the implantable device around the anatomic structure or lumen.

13. An implantable device adapted for use as an annuloplasty ring, comprising:
-
an adjustable implantable ring; an adjustment tool adapted to adjust the implantable ring; an elongated track member extending through an interior of the ring or arranged encircling an exterior of the implantable ring; and a coil configured to fasten the implantable ring to anatomical tissue, the coil arranged encircling the track member along a spiral path, wherein the coil is adapted to penetrate the anatomical tissue when spiraling the coil over the track member around the implantable ring adjacent the anatomical tissue or lumen. - View Dependent Claims (14, 15, 16, 17)
