Everything you need to know about your Ark Vascular Access Needle Guide

Your dialysis treatment is essential to your journey towards a stronger and healthier you. As part of your journey, your doctor has recommended using the Voyager Ark.

Use this guide to get to know the Ark, how it works, the benefits you’ll enjoy during and post-treatment, what to expect, and other valuable information that will help you get the most out of your Ark. 
Please ask your healthcare provider if you have questions about the Ark. You can also review the FAQ section in this guide for more information.

A small metal device, the Ark, was implanted by your doctor in the soft tissues around your vein. It will be a physical target to help your healthcare provider find your vein to insert needles during your hemodialysis treatment.

The Ark is also designed to enclose your vein for added protection from unintentional injuries, aiming to prevent damaging needle penetration that can cause blood loss through the back wall of your vein.

The Ark is made of titanium with a porous top and bottom and comes in four different models. Your doctor will tell you what size has been implanted in you. Your doctor will also determine when your Ark is ready for use, which may be in as little as six weeks.

Prevent Injury

Because the Ark protects your vein’s side and back walls, it may be less prone to unintentional injuries during needle insertion.

Uncomplicated Treatment

Going through hemodialysis is not easy, but with your Ark, you may have a better experience during treatment.

Reliable Target

Your Ark is designed to be a safe, reliable, and efficient target that guides your healthcare provider in inserting the needle into the right vein.

Save Time & Energy

Your treatment may be more comfortable and may be completed in less time.

Your Ark should be ready for needle insertions six weeks after the implant, depending on your doctor’s recommendations.

Your healthcare provider will give you a packet (Ark Patient Guide Kit) to ensure you have the essential information, including your implant card and accessories.

Carry your Ark Patient Guide Kit and accessories, as needed, when you go for hemodialysis treatment.

Show your healthcare provider your Implant Card before your hemodialysis treatment to help them correctly identify your Ark implant.

If it’s your first time using the Ark, ask your healthcare provider what to expect when the needle is put into and taken out of the device.

Watch for possible complications after your Ark implantation and Ark use during hemodialysis. Below are some of the events and symptoms to monitor:
  • You see signs of skin erosion or irritation around the implant area.
  • You feel pain in the implant area.
  • The implant area is bleeding.
  • You have a fever.
  • You feel nauseous.
  • The implant area is swollen, sore, crusty, red, or shows discoloration.
  • You experience chills.
Tell your healthcare provider immediately if you experience any of the above conditions.
