A Delivery System (Figures 2a, 2b, 2c)
The A delivery system (useable length 55 cm) is used for delivery of the
Edwards SAPIEN XT transcatheter heart valve. The delivery system has radiopaque markers
for visualization under fluoroscopy and a balloon for deployment of the valve. A balloon inflation
hub, a guidewire hub, and a pusher retraction feature are housed in the handle assembly. The
handle is labeled “BALLOON” at the balloon inflation hub and “WIRE 0.035"” at the guidewire
hub. The system also comes with a loader that is used to cover the valve during delivery. An
extension tube is supplied for use with the delivery system during inflation.

2.0 Indications
The Edwards SAPIEN XT transcatheter heart valve, model 9300TFX, and accessories are indicated
for relief of aortic stenosis in patients with symptomatic heart disease due to severe native calcific
aortic stenosis who are judged by a Heart Team, including a cardiac surgeon, to be at intermediate or
greater risk for open surgical therapy (i.e., predicted risk of surgical mortality
≥ 3% at 30 days, based
on the Society of Thoracic Surgeons (STS) risk score and other clinical co-morbidities unmeasured by
the STS risk calculator).
