DEVICE: EDWARDS SAPIEN XT TRANSCATHETER HEART VALVE (THV) (00690103192070)

An implantable xenograft (e.g., bovine, porcine) intended to be used to repair/replace a stenosed and/or regurgitant aortic heart valve, or previously-implanted aortic heart valve prosthesis, and which is designed to be implanted with a catheter via transarterial access (e.g., femoral, subclavian, aortic) or transapical access while the heart is beating. It is comprised of the xenograft, processed to render the tissue non-viable, attached to an expandable metal framework, which is implanted with an included catheter, and when in situ, may be expanded with a balloon or self-expand. Typically devices associated with implantation (e.g., catheter, introducer) are included.

An implantable xenograft (e.g., bovine, porcine) intended to be used to repair/replace a stenosed or regurgitant pulmonary heart valve prosthesis (previously implanted), or native pulmonary valve anatomy that may have been surgically repaired, and which is designed to be implanted with a catheter via vascular access. It may be attached to an expandable metal framework which may be expanded with a balloon or self-expand, and may include other material types (e.g., synthetic polymer). Devices associated with implantation (e.g., catheter, introducer) may be included.
