Method and device for intermittent occlusion of a vein draining the organ system
First Claim
1. A device for intermittent occlusion of a coronary sinus, comprising:
- a multi-lumen catheter having a distal end portion;
an occlusion device coupled to the distal end portion of the multi-lumen catheter and being in communication with a first lumen of the multi-lumen catheter, the occlusion device being adjustable between a non-occluding state and an occluding state that is configured to substantially occlude the coronary sinus,a pressure measuring device for measuring fluid pressure in the coronary sinus when the occlusion device is in the occluded state,a memory for storing fluid pressure behavior as a function of time, anda vibratory device configured to apply a pulsating pressure in pressure waves in the coronary sinus when the occlusion device is in the occluded state, wherein the vibratory device is mounted to the multi-lumen catheter at a position at least partially distal of the occlusion device and is in communication with a second lumen of the multi-lumen catheter.

Abstract
In a method for the intermittent occlusion of a vein draining the organ system, in which the vein is occluded by an occlusion device, the fluid pressure in the occluded vein is continuously measured and stored, the behavior of the fluid pressure is determined as a function of time, and the occlusion of the vein is triggered and/or released as a function of at least one characteristic value derived from the pressure measurements, pressure is applied during the occlusion in a pulsating manner. The device for the intermittent occlusion of a vein, including an occlusion device, a pressure measuring device for continuously measuring the fluid pressure in the occluded vein, and a memory for storing the fluid pressure behavior as a function of time, means are provided for applying a pulsating pressure in the occluded vein.
