The CUFF device is a flexible surgical retractor designed for exposure and access purposes when inserted into the aortic root and used to retract aortic wall tissue. The device consists of a main body component with retraction wings which are two-tiered and extend laterally. The posterior aspect of the device has a stabilization flange along the inferior border. Two alignment suture eyelet holes can be found within the medial portion of the stabilization flange.
An assembly of devices intended to be used during aortic valve replacement via aortotomy to facilitate temporary stabilization of the aortic root for improved aortic valve site exposure, visualization and tissue tension. It consists of a circular frame that is placed within the aortic ring, sutures and suture retaining loops, and a deployment device with handle and shaft; it may be used during minimally-invasive and open surgery. This is a single-use device.
