Implant with an annular base
The implant has an annularly bent base, whereby the imagined surface enclosed by the base is bent. Preferably the surface enclosed by the base is a symmetrical. It is particularly advantageous if the base is enclosed by a solid material and this is enclosed by a relatively soft material. This offers the possibility of designing fastening clips in the relatively solid material. Such implants are especially suited as heart valve rings.
1. An implant comprising:
(a) a base;
(b) a solid material annularly enclosing the base, an outer surface of said solid material defining a solid material perimeter, said solid material having a fastening clip, in which a thread can be fixed during implantation, said fastening clip defining an enlarged geometrical region of said solid material wherein said solid material perimeter is spaced from said base to a substantially greater extent than a second spacing between said base and said solid material perimeter at all remaining regions of said solid material; and
(c) a second material layer disposed about said outer surface of said solid material.
