Abstract

Method for the diagnosis and treatment of aortic aneurysms through representation of the affected area of the aorta by means of an imaging method and measurement of the image in order to produce a made-to-measure stent graft which is introduced into the aorta in the folded state and then expanded, a digital model of the aortic aneurysm being created from the images present as 3D volume data, from which digital model of the aortic aneurysm there is produced by means of iterative customizing software a digital model of the stent graft on the basis of which the stent graft is manufactured.

Claims

1-7. -7. (canceled)

8. A method of diagnosing and treating aortic aneurysms, comprising:

generating three-dimensional volume data of an area of an aorta affected by an aortic aneurysm for diagnosing the aortic aneurysm, by an imaging device;

developing a first digital model of the aortic aneurysm based on the three-dimensional volume data;

developing a second digital model of a stent graft based on the first digital model using an iterative customizing software, the stent graft configured to be inserted into the aorta in a folded state and to be expanded within the aorta;

manufacturing the stent graft based on the second digital model;

inserting the manufactured stent graft into the affected area of the aorta, the manufactured stent graft being in the folded state; and

expanding the stent graft within the affected area for treating the aortic aneurysm.

9. The method as claimed in claim 8, further comprising:

generating image data of the aorta during inserting the manufactured stent graft; and

merging the image data of the aorta with the first and/or second digital model.

10. The method as claimed in claim 9, wherein inserting the manufactured stent graft is supported by a medical imaging device chosen from the group consisting of a CT device, an MR device and an angiography device.

11. A device for diagnosing and treating aortic aneurysms, comprising:

an imaging device for generating three-dimensional volume data of an area of an aorta affected by an aortic aneurysm for diagnosing the aortic aneurysm;

an automatic or partially automated manufacturing station for manufacturing a stent graft configured to be inserted into the aorta in a folded state and to be expanded within the aorta;

a workstation connected to the imaging device and the manufacturing station, the workstation comprising;

a segmentation stage configured to develop a first digital model of the aortic aneurysm based on the three-dimensional volume data; and

an iteratively operating customizing stage for developing a second digital model of the stent graft based on the first digital model;

a display device for visualizing the three-dimensional volume data and/or the first and/or second digital model; and

a memory device for storing user data and control software, wherein the stent graft is manufactured by the manufacturing station based on the second digital model.

12. The device as claimed in claim 11, further comprising at least one medical imaging device chosen from the group consisting of a CT device, an MR device, an X-ray angiography system and an ultrasound system, the at least one medical imaging device connected to the workstation and configured to support inserting the manufactured stent graft into the affected area of the aorta by generating medical images of the aorta while inserting the manufactured stent graft into the affected area.

13. The device as claimed in claim 12, wherein the at least one medical imaging device is further configured to measure a blood flow through the aorta.

14. The device as claimed in claim 12, wherein the at least one medical imaging device is further configured to capture, edit, reconstruct, communicate and archive two-dimensional and/or three dimensional and/or four-dimensional image data.

15. The device as claimed in claim 11, wherein the imaging device is configured to merge medical image data including the three-dimensional volume data, the first and/or second digital model and physiological measurement data acquired from a patient undergoing aortic aneurysm treatment.

16. The device as claimed in claim 15, wherein the physiological measurement data are measurement data chosen from the group consisting of ECG data, blood pressure, blood flow, ventilation data acquired by an ventilator connected to the patient and anesthesia data acquired by an anesthesia system connected to the patient.

17. The device as claimed in claim 11, further comprising a correction module for ECG or breath gating to suppress artifacts.
