The Woggle technique is the purse-string suture modified using to close a puncture site after a percutaneous procedure.
Techniques common to all procedure include:
- a purse-string suture is done around the introducer sheath (the short plastic tube placed within a vein or artery)
- cut the needle off the suture and insert the two free ends of the suture through the tension collar (known as the Woggle device)
- remove the sheath out slowly while tightening the tension collar to achieve hemostasis
- the stopcock is then turn off to lock the suture
After a half of hour, one of the sutures can be cut very close to the skin and the suture removed.
