Surgical technique and considerations for implantation of electromagnetic blood flow transducer and occluder onto the coronary arteries.
A technique was developed for the implantation of an electromagnetic flow probe and vascular occluder onto the right and left coronary arteries in the calf and pony. Surgical manipulation was well tolerated in the animals. The subcutaneous housing on the peripheral ends of these devices of the lateral thoracic wall served as a maintenance-free technique for chronic exteriorization of these devices. Implantation onto the coronary arteries required a surgical technique which accomplished the prerequisites for proper flow probe function. A reactive hyperemic response was elicited in each animal by implanting an inflatable vascular occluder distal to the flow probe. The correct function of these devices postoperatively established the feasibility of this surgical technique for implanting these devices on the coronary arteries for chronic studies of coronary circulation.
