DEVICE: EDWARDS SAPIEN XT TRANSCATHETER HEART VALVE (THV) (00690103192087)

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.

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.
