The VWING is a subcutaneous needle guide that allows for repeatable and reliable hemodialysis access of an autogenous arteriovenous (AV) fistula. The VWING facilitates access to deep and difficult to cannulate fistulas, extends the usable length of fistulas, and can help salvage aneurysmal fistulas.
Palpation ridge indicates the fistula location and optimal skin insertion point.
Funnel shape guides the needle to a consistent vessel entry point.
Encapsulation by granulation tissue facilitates formation of a consistent tissue path between skin and vessel.
The VWING is a subcutaneous needle guide that allows for repeatable and reliable hemodialysis access of an autogenous arteriovenous (AV) fistula. The VWING facilitates access to deep and difficult to cannulate fistulas, extends the usable length of fistulas, and can help salvage aneurysmal fistulas. The VWING acts as a target for a single cannulation site, enabling use of blunt needles following establishment of a needle tract.
The VWING is comprised of a single piece titanium device that allows for repeated access of the fistula through a single puncture site for maintenance hemodialysis. The VWING is implanted beneath the skin through a simple surgical procedure and securely attached to the exterior fistula wall, making the VWING a subcutaneous and extra-vascular cannulation target.
The VWING is a tool that aids surgeons, nephrologists and cannulators in the ultimate goal of providing reliable and safe dialysis access.
Revising a fistula to improve cannulatability can be challenging for vascular surgeons and poses risks for patients. VWING provides a simple alternative, and may be the best option to revise uncannulatable fistulas.
|In SAVE Study, VWING Enabled Access to a Variety of Previously Uncannulatable Fistulas2|
|Inclusion Criteria||Number of Fistulas (%) (n=54)|
|Not palpable||37 (69%)|
|3 failed access attempts||23 (43%)|
|Deep (>6mm)||23 (43%)|
|Short segment||21 (39%)|
The single piece titanium VWING is easily implanted subcutaneously
Dialysis in patients with an arteriovenous fistula (AVF) requires successful cannulation, but safe, reliable, consistent cannulation can be very challenging. VWING™ from Vital Access helps remove barriers to cannulation.
|Very Low Infection Rate*|
|Adverse Events||Catheter (USRDS)||AV Fistula (USRDS)||VWING SAVE Study Rate2|
|Infection of access||1.45||0.18||0.038|

Constant site cannulation using blunt needles has been advocated as a means to overcomethe damaging effects of sharp needle cannulation experienced in rope ladder and area puncturecannulation techniques. Until now, buttonhole cannulation using a “freehand” technique was the only way to create a constant site. Buttonhole, however, has many limitations: it is unguided, relies heavily on the cannulator’s skill set and the patient’s anatomy, and is affected by shifting arm and fistula positions from one dialysis session to the next. Because there are no means to ensure a single cannulation path, multiple vessel puncture sites, increased trauma to the skin insertion point and other complications may result, leading to an increased risk of infection and aneurysm.
VWING’s unique design enables a new way of performing constant site cannulation:
VWING Guided Cannulation Technique standardizes the cannulation path and guides the needle to a single vessel entry point to ensure safe, consistent and predictable access.
