What is vascular access? Is it like having blood drawn?
Vascular access, also known as “vascular cannulation” has a few similarities to having blood drawn. Both involve having a needle inserted into a vein, although vascular access may involve an artery. That is about where the similarities end. Vascular access requires a doctor or surgeon to insert a larger needle into a deep vein or artery. This is usually done while the patient is under anesthesia. Because the vein or artery is too deep to see with the naked eye, vascular access typically uses ultrasound guidance. The ultrasound provides visual feedback but can be tricky to deal with- if the needle is not perfectly aligned in a specific plane, it won’t be at all visible on the ultrasound’s viewing screen. As one may imagine, any error with this procedure can result in expensive and painful complications, such as hematomas, retroperitoneal bleeding, and pseudoaneurysms.
What procedures can EVA be used for?
EVA was designed for obtaining vascular access, which is a procedure that begins a vast number of larger procedures. The potential for use is much greater than just vascular access though. Shown here are some procedures that could benefit from EVA.
Is EVA reusable?
Unfortunately, due to the need for sterility, EVA is a one time use disposable device.
Is EVA longitudinal or transverse?
EVA’s unique rail system enables physician preference by allowing for both longitudinal or transverse access.
What needle guide is currently standard? How does EVA offer improvement on existing guides?
While other needle guides do exist, they are rarely used in hospitals because they tend to be clunky, difficult to integrate, and they often just fail to work consistently and accurately. The current standard is to use sensory and ultrasound guidance to achieve access, which can be very effective but can also be time consuming and risky. EVA was developed by a surgeon, which means it uniquely meets the specific, nuanced needs of its users. Examples include a unique rail system to allow for differences in patient anatomy, transverse and longitudinal capabilities, a rotating cylinder for making real time adjustments without losing visual on the needle, and a quick release function so that the user can remove the ultrasound once access has been achieved without leaving the whole needle guide behind. Simply put, EVA integrates into the existing procedure protocol without adding extra steps or disrupting doctor’s routines.
