APPLICATIONS OF THE AMPLATZ SNARE DEVICE DURING INTERVENTIONAL RADIOLOGIC PROCEDURES

Amplatz gooseneck snare (Microvena, St. Paul, MN) is a recently developed device for the percutaneous removal of intravascular foreign bodies [1-5] (Fig. 1). In the past several years, Various other applications of this snare system have been devised for placing, replacing, repositioning, or removing guidewires, catheters, and other devices during interventional procedures. The Amplatz gooseneck snare, which has been described [1], comes in a variety of loop sizes and is provided with either 4- or 6-French guiding catheters, although substitution with any of several soft, blunt-tipped guiding catheters is possible [5]. The principal advantage of the Amplatz snare over past systems is that the loop is at a right angle to the catheter, easing the capture of foreign bodies, devices, or catheters.
