What is a Snare medical equipment?
A snare is a device that may be used to remove intravascular foreign bodies such as wires or coils. A snare consists of a wire with a nitinol loop at the end. The plane of the loop is oriented perpendicular to the long axis of the wire. The snare is advanced through a catheter.
Under fluoroscopic guidance, the loop is used to engage a free edge of the foreign body. The wire and loop are retracted into the catheter. This locks the foreign body between the snare loop and catheter. The snare, loop, and foreign body are then removed in unison.
