Elevate the Standard.
The world’s first device designed specifically to address the unique challenges of acute type A aortic dissection, specifically DeBakey Type I (ATAD I).
DANE Prevention – The stent-supported cuff of the AMDS and expansion of the device from the arch distally elevates and support the intimal flap. This reduces tension on the intima, media, and the suture line, avoiding the formation of DANEs in the friable anastomosis.1, 2
Positive Aortic Remodeling – By avoiding DANE and stabilizing the true lumen, AMDS induces positive aortic remodeling, defined by 3 key measures: true lumen expansion, false lumen reduction, and total aortic diameter stabilization.3
Malperfusion Resolution – AMDS-induced expansion of the true lumen demonstrates effective resolution of vessel malperfusion.1
Uninhibited Flow to Supra-Aortic Vessels (SAVs) – The novel stent design of AMDS allows for uninterrupted flow into the native SAVs without surgical manipulation (i.e., bypass).1
Minimal Time Added to Operation – AMDS prolongs the circulatory arrest time of the hemiarch procedure by only a few minutes, with additional time for suturing, without adding significant technical complexity.1,4
1. PTFE FELT CUFF
Component made of a PTFE felt tube is used to buttress and strengthen the aortic tissue in preparation to perform the conventional polyester graft to aorta anastomosis.
2. UNCOVERED NITINOL WIRE BRAIDED STENT
Expands and supports the true lumen across the aortic arch and descending aorta thereby stabilizing the aortic wall and promoting remodeling.
3. STENT SUPPORTED CUFF
The stent supported cuff of the AMDS and expansion of the AMDS from the arch distally, elevates and supports the intimal flap, reducing the tension on the suture line, avoiding the formation of DANEs in the friable anastomosis.
4. DESIGNED TO AVOID dSINE
When deployed in vessel, the distal ends of the stent are designed to point away from the aortic wall to avoid dSINEs.
1. RED CAP
2. GUIDEWIRE (GW) EXIT
Compatible with 0.035” GW (optional).
Ergonomic handle for easy grip during delivery.
4. GREEN CAP
To deploy/release the suture constraining the stent.
5. PROTECTIVE SHEATH
For simple and atraumatic introduction to the transected aorta (6 cm long).
6. LOADED STENT
Flexible catheter shaft for simple tracking of system and atraumatic to vessel.
7. PIGTAIL SHAPED TIP
Pigtail tip reduces risk of device tracking into FL via a entry tear/fenestration.
“Knowing that you’re giving people surgery that is not having any additional complexity but with a better outcome is very reassuring.”
A new tool in the toolbox for surgeons to do a better operation at the time of an index operation for a DeBakey I.
Proven Clinical Results
- AMDS Prevents DANE and Resolves Malperfusion, Inducing Positive Aortic Remodeling.
True Lumen Expansion
- DARTS study demonstrated sustained true lumen expansion ≥ 5.0 mm in aortic Zones 1-4 from pre-op to 3 years, post-op. 3
False Lumen Reduction
- DARTS study demonstrated complete or partial false lumen thrombosis in the majority of patients in Zones 0-4 at 3 years post-op.3
Total Aortic Diameter Stabilization
DARTS study demonstrated total aortic diameter stability or decrease in a majority of patients in Zones 0-2 and half of the patients in Zones 3 and 4 at 3 years, post-op.3
