Drug application during a CT scan
First Claim
1. A method of controlling a local application of drugs to a part of a body of a patient during a CT scan, wherein the drugs are transported in containers suitable for introduction into a bloodstream of the patient;
- wherein the containers prevent an application of the drugs;
wherein a first drug is transported in a first container, wherein a second drug is transported in a second container;
wherein the first container has a first resonance frequency;
wherein the second container has a second resonance frequency; and
wherein the first resonance frequency is different from the second resonance frequency;
the method comprising the steps of;
applying the first container and the second container to the bloodstream of the patient;
monitoring a heart beat rate of the patient during the CT scan; and
selectively rupturing at least one of the first container and the second container in proximity to the part of the body on the basis of the monitored heart beat rate, resulting in a local application of at least one of the first drug and the second drug respectively to the part of the body and a controlled change of the heart beat rate of the patient to reduce variations in the heart beat rate during the CT scan.

Abstract
Controlled local application of drugs to a certain part of a body of a patient may be of major importance during a cardiac CT scan. By transporting the drugs in containers which prevent an application of the drugs and by rupturing only those containers which are located in the vicinity of the part of the body of a patient to which the drugs have to be applied, a local application of the drugs may be performed. According to an exemplary embodiment of the present invention, the rupturing and therefore the application of the drugs may be triggered by a monitoring algorithm which evaluates changes in the heart beat rate of the patient. Advantageously, the method allows for a local delivery of the drugs on a fine time scale and therefore for a fast control of the heart beat rate during the CT scan.
