“I had no surgery and have no scar.”

“I am so happy to hear that Ellipsys has received FDA approval so other patients like me can benefit from this type of fistula. I had no surgery and have no scar. Amazing when I compare my AVF with others in the dialysis unit. There is no comparison.”
Theresa Torres, Tempe AZ

“I have a family member on
dialysis and his arm is all lumpy
and bumpy, not mine.”

My arm looks great! After my procedure, I had a bandage placed and my daughter took me to lunch.”
Paulette, Richmond, VA
Benefits
Finally, hemodialysis access that’s
minimally invasive and patient friendly.
No incisions. No sutures. This surgery-free, permanent solution is a long-awaited and welcome change for hemodialysis patients. The common surgical procedure for fistula creation has remained the same for half a century. But all that’s changed. Unlike surgery, the Ellipsys System uses an endovascular approach that leaves the skin scar-free

your hemodialysis treatments easier, safer and more efficient.

Procedure
How it Works
1
Guided by ultrasound, a tiny needle accesses the vein
2
Once the needle reaches the artery, a guide wire is put into place. The needle is removed and a sheath is advanced into the artery (not shown)
3
Next, the Ellipsys catheter is moved through the sheath, with the catheter tip positioned inside the artery
4
The catheter is closed and activated – creating a permanent connection between the vein and artery. Sutures are not required.
5
Finally, the catheter is removed resulting in AVF flow.
6
Upon completion of the procedure, the patient leaves with just a band aid.
Ellipsys Percutaneous Fistula Creation vs.
Surgical Fistula Creation

Maturation failure, risk of infection, and scars are common concerns for surgically-created fistulas, but the techniques now being utilized in percutaneous fistula creation help to minimize and eliminate some of those concerns for patients.

Surgical Fistula
Creation

Traditionally, vascular specialists or vascular surgeons have created fistulas through minor surgery. An incision is made in the arm, called an “open-approach,” and the surgeon or specialist will identify the vessels, create the AV fistula by suturing the artery and vein together, and finally suture the skin closed. The suture or clips in the wound will remain in place for 7-10 days and will then be removed.

Ellipsys Percutaneous
Fistula Creation

Percutaneous fistula creation is a minimally invasive procedure that requires only regional or local anesthesia with a procedure time of less than 30 minutes. Additionally, because the procedure uses an endovascular (within the vessels) approach, it leaves the vasculature and tissue around the AV fistula undisturbed, improving healing time and overall outcomes. Depending on which percutaneous fistula creation method is used, the patient will be left with one or two small puncture sites as opposed to a lengthy scar common with traditional surgical fistula creation.

Prior to the procedure, you will have on office visit with history, physical exam, and ultrasound of your arm. Bring all of your medicines or a complete list of your current medications including dose and frequency to the office visit. If you are not currently taking an anti-platelet medication (like Aspirin) you may be started on one prior to your procedure. On the day of your procedure arrange for transportation to and from your procedure. You will be sedated and/or have a nerve block during the procedure and are unable to drive.

The procedure is performed in an operating room with special ultrasound and X-ray equipment. You will lay on your back with your arm out to your side. Your arm will be sterilely scrubbed with antiseptic solution and draped for the procedure. Your skin will be numb from a nerve block or local anesthetic (numbing medication) will be administered. A vein at the elbow will be entered (like for drawing blood) and the procedure will be performed through this single venous access. There may be mild discomfort during the procedure. The procedure will take approximately 30 minutes. Once the procedure is completed pressure will be placed at the venous access site to stop any bleeding and a small bandage will be placed. You will return to your pre-procedure room for 60 to 90 minutes of recovery. 

  • Relax–don’t do anything stressful.
  • You may eat and drink as usual.
  • For 24 hours: don’t drive or use heavy machinery, don’t make any legal or financial decisions, don’t sign any important papers, don’t drink alcohol, and don’t lift anything any heavier than a 2-liter bottle of soda, don’t wear clothing that will press against your wound. After 24 hours post-procedure you can return to usual activities.

You may have some mild pain, swelling, and bruising at your puncture site.  This is normal.

You will not have any internal or external stitches. You will have a small bandage covering your needle puncture site.

  • Any worsening redness or swelling around the puncture site
  • Warmth around the puncture site
  • Pus present or oozing from the puncture site
  • Lack of pulse or weak pulse at the puncture site
