Rethink Vascular Access

Introducing the new everlinQ™ endoAVF System, the first endovascular device for creating an AV fistula for hemodialysis.[1] The system utilizes two 6Fr magnetic catheters and a radiofrequency (RF) energy generator to create a consistent, hemodynamic fistula.[2]

An evolution in AVF techniques

The everlinQ endoAVF is created with minimal vessel trauma, torque and tension, and improved flow dynamics with its side-to-side configuration–all factors associated with the negative remodeling that inhibits maturation of surgical AVF.[3-5]

 

 

The everlinQ endoAVF system enables the creation of an AVF in an additional anatomic location, deep in the arm, that is not typically used in creating a surgical AVF. What’s more, the endovascular AVF can be created with vessels as small as 2.0 mm in diameter.

 


 

How it works

2

1. Two thin, flexible, magnetic catheters are inserted into an artery and vein in the arm through a small puncture or incision.

 


3

2. When placed in proximity, the magnets in each catheter attract to each other, pulling the vessels together. After confirming alignment, the RF electrode is deployed.

3. The venous catheter, which contains the electrode, delivers a burst of RF energy to create a connection between the artery and vein. Then, the catheters are removed.

4. The fistula is confirmed with arteriogram to show that arterial blood is flowing to the low-pressure venous system, creating multiple options for cannulation.

 


 

The results

In the FLEX study, everlinQ™ endoAVF has shown compelling clinical outcomes.
