Abstract

The present invention provides a package comprising an aortoiliac artery graft and a record of a measured pressurized diameter of the aortoiliac artery graft, which measurement has been determined ex vivo under a pressure. A method of processing an aortoiliac artery graft is also provided. The processing method comprises subjecting an aortoiliac artery to a pressure ex vivo, and determining a measured pressurized diameter of the aortoiliac artery under the pressure. A method of treating abdominal aortic aneurysm, infected aortoiliac endograft or a traumatically damaged abdominal aorta or an iliac artery in a patient is further provided. The treatment method comprises anastomosing a processed aortoiliac artery graft with an aorta of the patient on the proximal end and the iliac or femoral arteries on the distal end, wherein a measured pressurized diameter of the processed aortoiliac artery graft has been determined ex vivo under a pressure.

Claims (22)

1. A package comprising an aortoiliac artery graft and a first record, wherein the first record provides a measured pressurized diameter of the aortoiliac artery graft, and wherein the measured pressurized diameter has been determined ex vivo under a pressure.

2. The package of claim 1 , wherein the measured pressurized diameter is a measured pressurized outer diameter of the aortoiliac artery graft.

3. The package of claim 1 , wherein the measured pressurized diameter is a measured pressurized inner diameter of the aortoiliac artery graft.

4. The package of claim 1 , further comprising a second record, wherein the second record provides a measured unpressurized diameter of the aortoiliac artery graft, wherein the unpressurized diameter has been determined ex vivo during processing.

5. The package of claim 4 , wherein the measured unpressurized diameter is a measured unpressurized outer diameter of the aortoiliac artery graft.

6. The package of claim 4 , wherein the measured unpressurized diameter is a measured unpressurized inner diameter of the aortoiliac artery graft.

7. The package of claim 1 , wherein the aortoiliac artery graft comprises a full aortoiliac artery, an abdominal aorta distal to renal arteries inclusive of iliac arteries to an iliofemoral junction, or an abdominal aorta distal of renal arteries and inclusive of at least 1 cm of an iliac artery.

8. The package of claim 1 , wherein the aortoiliac artery comprises a distal aorta and iliacs without renal arteries.

9. The package of claim 1 , wherein the aortoiliac graft comprises an aorta distal of a diaphragm to iliofemoral junction.

10. The package of claim 1 , wherein the aortoiliac artery graft comprises an aorta artery and one iliac artery.

11. The package of claim 1 , wherein the aortoiliac artery graft comprises an aorta artery and two iliac arteries.

12. A method of processing an aortoiliac artery graft, comprising

(a) subjecting an aortoiliac artery to a pressure ex vivo during processing, and

(b) determining a measured pressurized diameter of the aortoiliac artery under the pressure, whereby a processed aortoiliac artery graft is obtained.

13. The method of claim 12 , wherein the pressure is controlled by using a pressure relief valve or a calibrated syringe.

14. The method of claim 13 , wherein the measured pressurized diameter is determined by using a tool selected from the group consisting of a ruler, a caliper, an umbilical tape, a laser micrometer and ultrasound.

15. The method of claim 12 , wherein the pressurized diameter is a measured pressurized outer diameter of the aortoiliac artery.

16. The method of claim 12 , wherein the pressurized diameter is a measured pressurized inner diameter of the aortoiliac artery.

17. A processed aortoiliac artery graft prepared according to the method of claim 12 .

18. A method of treating abdominal aortic aneurysm, infected aortoiliac endograft or a traumatically damaged abdominal aorta or an iliac artery in a patient, comprising anastomosing a processed aortoiliac artery graft with an aorta of the patient on the proximal end and the iliac or femoral arteries on the distal end, wherein a measured pressurized diameter of the processed aortoiliac artery graft has been determined ex vivo under a pressure.

19. The method of claim 18 , further comprising matching the measured pressurized diameter of the processed aortoiliac artery graft with a diameter measurement of the aorta of the patient before the anastomosing step.

20. The method of claim 18 , wherein the measured pressurized diameter of the processed aortoiliac artery graft is within 90-110% of the diameter measurement of the aorta of the patient.
