Fig 1 Platinum lead made by winding 25 strands of platinum wire having a diameter of 0.05 mm. The lead is covered with a silicone tube 2 mm in diameter and 50 cm long. The platinum wire is exposed for the final 1-cm tip portion of the lead, and unwound into a broom shape. The Annals of Thoracic Surgery 2002 73, 322-324DOI: (10.1016/S0003-4975(01)03396-3)
Fig 2 Translucent acrylic mold to make the bio-mini-paddle has a cylindrical groove in the center. The diameter of the groove is 20 mm, the depth is 10 mm. The Annals of Thoracic Surgery 2002 73, 322-324DOI: (10.1016/S0003-4975(01)03396-3)
Fig 3 The bio-mini-paddle is translucent and does not adhere to the myocardium. The Annals of Thoracic Surgery 2002 73, 322-324DOI: (10.1016/S0003-4975(01)03396-3)
Fig 4 Bio-mini-paddle 1 week after implantation. The electrode has decreased in size from the initial 20 mm to 18 mm in diameter, and from 6 mm to 3.5 mm in thickness. The reduction in volume was 47%. The Annals of Thoracic Surgery 2002 73, 322-324DOI: (10.1016/S0003-4975(01)03396-3)
