Application No. 08/748,637
placing the aorta on a tourniquet and transversely cutting the
aorta. A resilient tubular casing (1) housing the repair device
(3), which device is wound onto and carried by a prosthesis-
fitting means (5) having inflatable bulb structures (6), is
inserted into the open end of the aorta formed by the transverse
cut. Once properly positioned in the aorta, a pump (7) supplies
a physiological solution through the rubber pipes (8) to the
resilient bulbs (6) which, with the help of the spring-operated
carriage (10) and the flexible linkages (11), guide the repair
device in the radial direction until it is fully in contact with
the inner wall of the aorta, where the splints or pins on the
brackets (4) at each end of the repair device are thrust into the
walls of the aorta by the force generated by the bulbs (6)
inflated with physiological solution. Subsequently, the
physiological solution is drawn off and the resilient bulbs (6)
return to their original deflated position. The flexible
linkages (11) which held the repair device in a collapsed
position on the prosthesis-fitting means (5) are then cut and the
placement mechanism for the repair device is extracted from the
aorta and the aorta sewn up by the usual method. Likewise, the
retroperitoneal entrance would be closed by the usual method.
