CATHETER FOR COMMON TRACING OF LEFT AND RIGHT CORONARY ARTERY

摘要

PURPOSE:To introduce easily, safely and quickly one catheter either into left or right coronary artery solely regardless of symptom without incising a blood vessel. CONSTITUTION:This catheter has an outer diameter of below 2.1mm over the entire length and the body thereof comprises a far tip part (A) of 8-20mm length, a successive first roughly linear part (L1) of 14-25mm length, a second roughly linear part (L2) of 10-22mm length and a third roughly linear part (L3). The curvature radius R(A) is 6-18mm for a bending part of the A, that R(A1) from the A to the L1 is 6-13mm, that R (L12) of the bending part over the L1 and L2 is 4-10mm and that R (L23) of the bending part from the L2 to L3 is 16-22mm. An angle alpha (A1) between the A and L1 is 128-145 deg., that alpha (L12) between the L1 and L2 is 30-50 deg. and that alpha (L23) between the L2 and L3 is 120-135 deg. and that (L13) between the L1 and L3 is 85-95 deg..
