A revolution in AV fistula care

VasQ™ was designed to improve maturation and patency rates of AV fistulas. the VasQ™ provides external support thereby addressing the root causes of fistula failure:

  • Regulates flow by constraining and shaping optimal geometrical parameters of the fistula
  • Reinforces and shields the vulnerable perianastomotic vein against high pressure, wall tension and flow levels

null
The anastomosis is constructed in a routine manner without any intervention or interference.
null
The placement of the VasQ™ around the anastomosis is quick and does not prolong procedure duration.
null
There is no contact of the VasQ™ with the blood circulation and no suturing to the blood vessel.

Treating the root cause of fistula failure

VasQ™ targets vessel segments which are immediately proximal and distal to the anastomosis, where turbulent flow and intimal hyperplasia are most significant and where frequent occlusions occur, aiming to:

null

Control geometrical configuration

null

Control flow patterns

null

Reduce wall tension on the vein

null

Increase wall shear stress

METHODS

  • 20 patients received VasQ™ implant for their end-to-side Brachiocephalic fistulas
  • Patients were followed for 6 months
  • Study end-points included:
    • Fistula maturation – Blood flow rate and vein diameter as assessed by Doppler Ultrasound examination
    • Fistula patency – Assessed by Doppler Ultrasound examination

SAFETY

  • Low complications rate
    • No device-related serious adverse events
    • Minimal access-related complications
    • No interference with the dialysis needle, as the VasQ™ is placed distal to the needle
    • No contact with blood, as the device is placed externally

IMPROVED FISTULA OUTCOME

  • 93% of patients who had active dialysis at 6 months received dialysis through the study fistula
  • 79% of study fistulas have matured after 8 weeks
  • Increased success rate of the AV fistulas
    • Improved fistula patency rates over the standard of care
    • Superior fistula flow rate and vein diameter at 1, 3 and 6 months
