A vascular filter retrieval device comprising a catheter and a loop for engaging a filter is described. The loop is extendable from a proximal end of the catheter and comprises a resilient wire. The wire may be a metal alloy such as an ELGILOY® alloy. The loop is typically radiopaque and may have a platinum or palladium wire coiled around at least a part thereof. Also described is a method of retrieving a vascular filter from a patient using the device. The catheter is introduced into the vena cava of a patient adjacent the filter.
