Abstract
A system and method for extracting a pVAD device that is implanted with a distal portion in an aorta of the heart and a drive line extending across an inter-atrial septum and out of the body via a superior vessel of the venous vasculature, include a first device that is introduced into a femoral artery and through the descending aorta used to engage a distal part of the pVAD device in the aorta of a patient using an instrument. A second, cutter, device is introduced into the venous vasculature superior to heart, advanced to a position adjacent the inter-atrial septum, and used to cut the pVAD drive line adjacent to the inter-atrial septum. After cutting, a first portion of the pVAD is withdrawn from the body via the venous vasculature, and a second portion is withdrawn from the body via the femoral artery.
