Multiple Size Options for a Personalised Approach
The standard portfolio has a wide range of sizes and tapers, allowing each patient access to the right solution, every time.
One of the key benefits of RelayPro is being able to choose from a range of proximal configurations allowing me to tailor my device selection to meet the individual needs of each patient.2
Designed to Respect the Thoracic Anatomy
The RelayPro stent graft is divided into performance zones. Each zone is designed to serve a specific purpose and therefore distributes an appropriate radial load independent of other zones.
Uniform Sealing and Secure Fixation
Both RelayPro Bare Stent and Non Bare Stent offer multiple sealing points.
Bare Stent Configuration
Partial overlapping of the bare stent with the first covered stent to maximise the number of sealing points.
Non Bare Stent Configuration
A crown-shaped nitinol stent overlapping with the proximal sealing stent, both covered with fabric, designed to maximise conformability and minimise infolding.
High Radial Load
Both proximal configurations are designed to deliver high radial load for an effective apposition and fixation of the graft against the aortic wall.
Ahead of the Curve with the S-Bar Technology
S-Bar, an s-shaped nitinol wire, intended to provide columnar strength to the endograft and to enhance conformability by adapting to the natural curvature of the aorta.
Shortened length to optimise the treatment in tortuous aortas, enabling the more distal portion of the graft to flex in any direction.
RelayPro NBS: Designed to minimise Bird-beaking and Retroflex
RelayPro NBS, the only thoracic endograft available on the market with a Non-Bare Stent configuration that can be used as a standalone proximal component.
Minimises the risk of retroflex
During deployment, two support wires* guide the inferior portion toward the inner aortic wall, keeping it aligned with the landing zone, minimising the risk of retroflex
Ability to reposition
Two clasped stent apices, both located on the outer curve of the RelayPro NBS, for a precise and controlled deployment, preserving the ability to reposition
Minimises the risk of birdbeak
The Flared End configuration of the inner sheath enables partial expansion to improve the proximal alignment and precision for a correct apposition on the inner curve, minimising bird-beaking
Accurate deployment with favorable apposition even in hostile aortic arches contributed to low rates of early and midterm complications 3 ^
* Support wires are only present in devices with 32mm or greater proximal stent-graft diameters.
^This study included all RelayPro configurations with the NBS being predominant. The RelayPro is not indicated for erosion and rupture and the FDA-approved device is further not indicated for IMH and only intended for the DTA. Approved indications will vary by region, always consult the corresponding IFU.
Deployment System
Precise, Accurate, and Controlled to Navigate the Arch with Care.
RelayPro’s ability to land accurately combined with its low profile will allow me to successfully treat complex anatomy with precision.4
Proximal Clasping
- Allows for repositioning of the device and facilitates perpendicular deployment
Pre-Curved Inner Catheter
- Conforms to the aortic arch designed for alignment of the stent-graft
Soft Inner Sheath
- 30cm length
- Designed to provide navigability and to ensure accurate deployment, minimising trauma to surrounding anatomy
Coiled Outer Sheath
- 60cm length
- Designed to provide pushability and support during the advancement and manoeuvring through access vessel
Controller
- Allows for staged deployment enhancing control and accuracy in stent-graft placement
Mechanical Advantage
- Forward and backward gear system allows for small incremental movements of the stent-graft enhancing controlled delivery
Non Bare Stent Configuration
Two clasped stent apices, both located on the outer curve of the RelayPro NBS
Bare Stent Configuration
Variable bare stent heights depending on proximal diameter
RelayPro's ability to navigate smoothly over the arch as a result of the Dual Sheath system enables accurate deployment […].2
Thinking Ahead with On-Label Endovascular Extension with Thoraflex™ Hybrid
If the lesion requires use of a distal extension, only a Relay NBS configuration should be used:
- 44 year old patient
- Acute type A aortic dissection repaired with Thoraflex Hybrid, extended with RelayPro NBS thoracic stent graft system
With up to 33% of FET repairs needing a future aortic reintervention, on-label endovascular extension using RelayPro with Thoraflex Hybrid, is indicated to complete the downstream repair * 5
* Reinterventions included endovascular, open surgery or hybrid approaches. Note the Thoraflex Hybrid is ONLY indicated for treatment in cases of aneurysm and/or dissection. The CE-marked RelayPro is contraindicated in patients with connective tissue disorders.
Please refer to the device IFUs for complete indications, contraindications, warning’s and precautions.
