41.   A plug to stop bleeding in patients who have undergone balloon angioplasty was approved Monday by the U.S. Food and Drug Administration.

42.   All three laser techniques typically require conventional balloon angioplasty as a follow-up.

43.   Balloon angioplasty does not involve surgery and the blockage is removed by inserting a thin tube through the body into the artery and manipulating it.

44.   Balloon angioplasty does not involve open-heart surgery.

45.   Balloon angioplasty involves inserting a thin tube into the body through an artery and inflating a small balloon at the end to clear blockages.

46.   Branstad underwent a standard angiogram that revealed blockage in one heart artery, and doctors then performed a balloon angioplasty to reopen the blood vessel, he said.

47.   But new clots can form after balloon angioplasty, or the artery can narrow again, while drugs carry a significant risk of serious bleeding and stroke.

48.   Good results with conventional balloon angioplasty also have slowed the pace of laser research.

49.   He again underwent balloon angioplasty, which does not involve open-heart surgery.

50.   In balloon angioplasty, a tiny balloon is inflated inside a blood vessel to compress fatty buildup on the artery walls.
