Aditlys develops a novel vascular access graft using a unique material technology
Aditlys’ grafts utilize a porous material made of a patented biodegradable polymer.
Once implanted, the device triggers a unique process of tissue restoration, called Endogenous Tissue Restoration, or ETR, that eventually leads to the resorption of the graft and its replacement by an actual blood vessel.
With this particular approach, Aditlys is expecting to reduce the complications faced routinely by the patients undergoing hemodialysis. The ambition is to define a new standard of care for vascular access that will improve the quality of life of millions of people.
Early stage developments are done and the project is currently entering its final phase.
Aditlys is bringing a game changing technology in a market estimated to be worth a few billion dollars.

Today, there are more than 3 million persons in the world that are in the terminal stage of renal disease (ESRD patients), meaning that their kidneys are not functional anymore. This is a life-threatening condition, as dangerous levels of waste products accumulate in the blood, threatening the organs.
Some of those patients (2%) will be able to benefit from a renal transplantation. But compatibility issues and a shortage of donors means that most of them will in fact have to wait for years and undergo hemodialysis in the meantime.
3 to 4 times a week, by sessions of 5 to 6 hours on average, they will get connected to a machine, a dialyzer, that will pump and clean their blood. For that to happen, however, an access path must be developed prior to the first treatment to ensure sufficient flow make it to the machine.
3 treatment options are currently available for patients suffering from ESRD.
The surgical creation of an arteriovenous fistula: in this process, the surgeon will connect a vein and an artery in the forearm of the patient. This will increase the flow in the vein to the desired level, expanding it by the same occasion and forming a “pocket” through which the nurse will be able to puncture. This approach is currently the gold standard, as it offers the longest patency with the lowest re-intervention rate. But the puncture cannot be performed before the “pocket” has stabilized, which takes some time, usually 4 to 6 months, time during which the patients are usually treated using a central catheter.
The implantation of an arteriovenous graft: in this situation, the connection between the vein and the artery is done using a graft made of synthetic material. The device is designed so that the nurse can puncture directly through the graft, saving weeks of maturation. This solution is a good alternative for patients with no vein available for the creation of a fistula. Yet, it does come as well with a very high cost: the risk of infection is much higher than with a fistula and 50 % of grafts become occluded before the end 6th month.
The use of a central venous catheter: in this situation, a catheter will be placed via the jugular or subclavian veins. This solution is immediately available and almost systematically used in the event of an emergency. Yet, the trans-dermal positioning is a door open to infections and the complications are potentially very severe. This approach is preferably used as a short term or last resort solution.
To tackle those issues, Aditlys is developing a novel graft, made of very specific polymer. This material comes from Nobel Prize awarded research and is the result of over a decade of Research and Development.
As it is implanted, the contact with blood will trigger a process called Endogenous Tissue Restoration, or ETR: the patient’s natural healing response develops tissue that will fill the porous structure of the graft. But as this process occurs, the material will also resorb, eventually resulting in an actual blood vessel made from the patient’s own cells.
This is the uniqueness of Aditlys’ approach: the implant works as a normal vascular access graft once implanted but turns into a fistula after a few months.
This approach may help to combine the short- and long-term advantages of both existing options, eventually improving the quality of life of millions of patients throughout the world.
Once implanted, this graft, made of bioabsorbable polymer, works as a normal medical device that creates an immediately viable access point. However, with ETR, the patient’s natural healing response develops tissue that fills the porous structure of the graft, and develops a new, natural blood vessel. As ETR occurs, the graft is gradually absorbed by the body.
Aditlys’ aXess grafts may help to combine the short- and long-term advantages of existing options and improve the life of millions of patients dependent on dialysis to stay alive.
