Perceval^™ Plus RelyON System

Designed for durability

The FREE tissue treatment in Perceval Plus addresses both major causes of valve calcification, phospholipids and aldehydes. It also allows the valve to be stored in an aldehyde-free solution, which means negligible toxicity for the patient and a faster procedure for the surgeon, as no rinsing is required.

• Superelastic stent. Self-expands in place with no need to knot sutures, ensuring optimal valve sealing and reducing the stress transferred to the leaflets. Carbofilm coated to reduce inflammatory reaction and favour gentle endothelialisation.
• Double sheet design. An outer sheet acts as a cushion that minimises stress transferred to the leaflets.
• Fully atraumatic collapsing. The collapsing procedure does not affect the leaflets, preventing damage to the tissue.

The Perceval platform has shown a linearised rate of SVD of 0.54% per patient-year, with a maximum follow-up of 13 years.

Designed for haemodynamics

The superelastic Nitinol stent lets Perceval Plus follow the physiological movement of the aortic root during the cardiac cycle, mimicking the native valve.

Ready for valve-in-valve

The stent design allows even circumferential expansion to accommodate future transcatheter valves, making Perceval Plus ViV friendly by design.

• Clear visibility. The Nitinol stent is clearly visible under fluoroscopy and CT scan, identifying landmarks that facilitate the ViV procedure.
• Even circumferential expansion. The inflow ring can be expanded evenly up to 2.5 mm above its nominal size, for haemodynamic advantages and greater compatibility with TAVI models and sizes.
• Minimised risk of coronary obstruction. The leaflets remain open when a TAVI is deployed inside the valve, preserving a space between the coronary ostia and the leaflets.
• Minimised risk of sinus sequestration. When open, the leaflets do not touch the STJ.

Designed for MICS

The sutureless design of the valve, and the length and diameter of the delivery system, suit minimally invasive cardiac surgery: a reduced incision and less surgical trauma, full visibility of the annulus during implantation and deployment, a faster learning curve and reduced manipulation of the aortic root.

The RelyON delivery system

RelyON was designed in partnership with surgeons and nurses for an easy, fast procedure, from unboxing to deployment.

• Precise. Delivers the valve with a single movement of the hand while keeping a firm hold on the device, for precise positioning in the aortic root.
• User-friendly. Top-loading valve, self-locking lever, infographics, open-close guide and all-in-one packaging.
• Optimised for MICS. The length and small diameter of the shaft, with the collapsible valve, allow a minimised incision and easier access to the implantation site.
