Table 1. The AVP family.

Version	Details	Comments
AVP I	Provides rapid occlusion with precise positioning in short landing zones Single-layered cylindrical disk Available in diameters ranging from 4 to 16 mm Requires 4–6F sheaths	Not very thrombogenic in high flow situations, many times requiring placement of other embolics Easy placement
AVP II	Provides faster occlusion and can adjust to the variable landing zones Made out of a densely braided multilayer nitinol mesh with three components generating six barrier planes for acceleration of vascular occlusion Sizes: 3–22 mm Requires 4–7F sheaths	Faster occlusion Longer segment needed The 3 lobes can be shortened by compression, allowing for better sealing and fitting into a shorter landing zone
AVP III	Provides even faster occlusion, enhanced performance in high flow situations and improved wall apposition in challenging cases Sizes: 4–14 mm Requires 4–7F sheaths	Not available in the United States
AVP IV	Reaches distal vasculature through tortuous anatomy and is compatible with select diagnostic 0.038-in inner lumen catheters Sizes: 4–8 mm	Difficult to inject contrast using the provided valve For occlusion of medium-sized (3–6 mm) vessels

Abbreviation: AVP, Amplatzer Vascular Plug.
