An experimental model of saphenous vein-to-coronary artery anastomosis with the St. Jude medical stainless steel connector  Hartzell V Schaff, MD, Kenton J Zehr, MD, Luis F Bonilla, MD, Lucas H Brennecke, DVM, Todd Berg, BS, Rick Cornelius, BS, Paul Hindrichs, BS, William Swanson, BS  The Annals of Thoracic Surgery  Volume 73, Issue 3, Pages 830-836 (March 2002) DOI: 10.1016/S0003-4975(01)03445-2

Fig 1 Connector and delivery system. The Annals of Thoracic Surgery 2002 73, 830-836DOI: (10.1016/S0003-4975(01)03445-2)

Fig 3 The connecting device is inserted axially into the coronary artery (A), and inflation of the balloon expands and shortens the connector (B). After the balloon and nosecone are removed, the distal portion of the graft is ligated close to the anastomosis (C).
