Abstract
In a method for locating an arterial constriction and performing an arteriotomy distally thereof, especially with a view to establishing a bypass connection between the aorta (52) and a part of the coronary artery (51) distally of a constriction in the artery, the most important steps are locating the site of the constriction in the artery (51), preferably by using an instrument (9) with a head (3) carrying an ultrasonic transducer array (not shown), and making an incision in the artery (51) closely distally of the constriction, preferably by using a knife (not shown) placed in said head (3).
