Abstract
Some systems and methods for operating a vessel occlusion catheter may include a control and inflation device to control the filling of the balloon in such a manner that the vessel wall will not be overstressed while the safe occlusion of the blood vessel is achieved.
Claims20
A control and inflation device, comprising:
- a coronary sinus occlusion catheter having an inflatable balloon, an inflation lumen, and a connection for the inflation lumen of the coronary sinus occlusion catheter, and
- switching valves arranged in a manner that the connection for the inflation lumen is alternately connectable with a vacuum tank and with a pressure tank;
- wherein the switching valves are configured to switch the inflation lumen to a connection with the vacuum tank in response to an inflation time for filling the inflatable balloon being detected to be below a predetermined lower limit.
A control and inflation device, comprising:
- a coronary sinus occlusion catheter having an inflatable balloon, an inflation lumen, and a connection for the inflation lumen of the coronary sinus occlusion catheter, and
- switching valves arranged in a manner that the connection for the inflation lumen is alternately connectable with a vacuum tank and with a pressure tank;
- wherein the switching valves are configured to switch the inflation lumen to a connection with the vacuum tank in response to a detected pressure in the inflatable balloon reaching a value greater than an upper limit selected between 90 and 120 mm Hg.
