For patients requiring intra-aortic balloon (IAB) therapy but cannot take it through the usual femoral artery, it is necessary to open the chest to directly insert the IAB directly to the artery. A new process includes a transthoracic aortic sleeve of teflon or woven dacron tubing 30-40 cm. long formed with a brim at the aortic end and a closed conical exterior end. The conical exterior end is threading through a small incision in the skin and the conical end is then cut off and replaced with a one-way valve. Then a purse string closure is stitched on the adventitial wall of the aorta around the IAB entry point, the sutures of the purse string passing into the sleeve brim. A small incision is then made in the center of the purse string, the IAB is inserted and the purse string tightened and tied. The sleeve prevents blood loss into the chest cavity and keeps all blood loss to a minimum, especially during removal of the IAB.
