Abstract
As the cases for bleeding to occur in the large volume at insertion of IABP, we see that the gap between the thick sheath in about 10F and a slender guide wire in 0.035 inches left there is wide, causing bleeding while a balloon catheter is pushed forward along the guide wire. We have developed a new sheath with a grooved anti-bleeding plug preliminarily attached to the distal portion of the sheath. Bleeding is avoidable by inserting the anti-bleeding plug immediately into the gap between the sheath and the guide wire after pulling out the dilator. This plug i s removed without being hasty at the point of time when the balloon catheter advanced to the sheath along the guide wire, and the balloon catheter is inserted into the sheath. Result of experiment: To the volumes of bleeding when no plug was used being 600ml/min, the volumes of bleeding with the plug attached were small as 9-18ml/min(average11.5ml/min)
