A lesion marker to facilitate placement of the Simpson's atherocath device during directional atherectomy of left anterior descending coronary artery stenoses.
Placement of the directional coronary atherectomy cutter requires frequent angiographic contrast injections to aid in the precise location of the device in relation to the target stenosis. A method is described to enable rapid positioning of this device across stenotic lesions occurring in the left anterior descending coronary artery, with the use of a simple lesion marker. Two short lines demarcating the limits of the stenotic lesion are drawn onto a transparent one-sided adhesive plastic sheet that has been pasted beforehand onto the active monitor screen. Using this reference marker, the atherectomy device can be reliably positioned across the stenotic lesion.
