<p>Medical implants, installation tools, and methods of installation for minimally-invasive surgery wherein the implants, tools, and/or implantation site are marked with structure having enhanced visibility. The enhanced visibility markers may be highly reflective or luminescent; that is, the markers may be fluorescent, luminescent, or chemiluminescent. Metallic markers, such as gold, platinum, or stainless-steel may be used. The implant may be for cardiovascular surgery, and may have fabric thereon on which the enhanced visibility marker is provided. For example, the marker may be provided on a sewing ring of a heart valve, or on the exterior of an annuloplasty ring. A marker may be placed at anatomical location at the implantation site for better visualization thereof. An enhanced visibility marker on the implant may then be registered with the marker at the anatomical location. Sutures for attaching the implant to the host tissue, or for attaching an installation tool to the implant, may be made of a material, or treated, so as to have enhanced visibility.</p> |
