generating an image from the light received by an image generation device using the optical coherence tomography; delivering a rinsing fluid into a section of a vessel of a patient containing the transmitter and receiver using a rinsing device; sealing the vessel with an occlusion device; and automatically controlling an operation of the image generation device and the rinsing device, and the occlusion device using a control device according to a predetermined program, wherein the control device controls a displacement device to displace the catheter in a direction of an axis of the catheter or to rotate the catheter with the axis when the rinsing fluid is delivered. ### Claim 2 (depends on 1) The method as claimed in claim 1, wherein the operation is controlled so that the image generation device and the rinsing device are switched on simultaneously and the rinsing fluid is delivered at a predetermined rate. ### Claim 3 (depends on 2) The method as claimed in claim 2, wherein the rinsing device delivers the rinsing fluid for a predetermined time period or a predetermined quantity. ### Claim 4 (depends on 1) The method as claimed in claim 1, wherein the control device controls an occlusion device for sealing the vessel and controls the rinsing device to deliver the rinsing fluid before the vessel is sealed. ### Claim 5 (depends on 4) The method as claimed in claim 4, wherein the control device comprises a regulator which regulates a pressure required for activating the occlusion device. ### Claim 6 (depends on 4) The method as claimed in claim 4, wherein an operating state of the occlusion device is displayed on a display device. ### Claim 7 (depends on 1) The method as claimed in claim 1, wherein the control device interrupts the delivery of the rinsing fluid when the displacement is terminated. ### Claim 8 (depends on 1) The method as claimed in claim 1, wherein an operating state of the displacement device and the rinsing device is displayed on a display device. ### Claim 9 A device for generating an image using optical coherence tomography in a medical procedure, comprising: a catheter with a transmitter and a receiver for transmitting and receiving light; an image generation device for generating an image from the light received using the optical coherence tomography; a rinsing device for delivering a rinsing fluid into a section of a vessel of a patient containing the transmitter and the receiver; an occlusion device for sealing the vessel, a displacement device for displacing the catheter in a direction of an axis of the catheter or to rotate the catheter with the axis, and a control device operatively connected to the image generation device, the rinsing device, displacement device, and occlusion device for automatically controlling an operation of the image generation device and the rinsing device, displacement device, and the occlusion device, wherein the control device controls the displacement device to displace the catheter when the rinsing fluid is delivered. ### Claim 10 (depends on 9) The device as claimed in claim 9, wherein the control device controls the operation so that the image generation device and the rinsing device are switched on simultaneously and the rinsing fluid is delivered at a predetermined rate. ### Claim 11 (depends on 9) The device as claimed in claim 9, wherein the control device controls an occlusion device for sealing the vessel and controls the rinsing device to deliver the rinsing fluid before the vessel is sealed. ### Claim 12 (depends on 11) The device as claimed in claim 11, wherein the control device comprises a regulator to regulate a pressure which is required to activate the occlusion device. ### Claim 13 (depends on 9) The device as claimed in claim 9, wherein the rinsing device delivers the rinsing fluid for a predetermined time period or a predetermined quantity before the displacement of the catheter. ### Claim 14 (depends on 9) The device as claimed in claim 9, wherein the control device interrupts the delivery of the rinsing fluid when the displacement is terminated. ### Claim 15 (depends on 9) The device as claimed in claim 9, wherein the control device comprises a processing computer. ### Claim 16 (depends on 9) The device as claimed in claim 9, wherein the device comprises a display device to display an operating state of the rinsing device, a displacement device, and the occlusion device.
