Device for a dynamically sealing occlusion or a space-filling tamponade of a hollow organ

A device for the sealing occlusion and/or for the space-filling tamponade of a hollow organ or a cavity in a human body, comprising a prcfcrably fully and residually formed balloon (2) which is intended to be configured to apply an appreciably constant sealing pressure to a wall of the hollow organ or cavity to be occluded or tamponaded in use, comprising a regulating unit for a filling pressure within the interior of the balloon (2), which regulating unit is intended to be configured to be situated extracorporeally outside of the human body during use and comprises an extracorporeal volume reservoir (9) which is intended to be configured to be situated extracorporeally outside of the human body in use, and a feed line (6) for communicatively connecting the extracorporeal volume reservoir (9) to the interior of the balloon (2), wherein the connecting feed line (6) between the balloon (2) and the extracorporeal volume reservoir (9) comprises (i) a supply channel with a cross-sectional area corresponding to a circular cross-sectional area with a diameter of at least 2 mm, (ii) a flow-directing one-way valve (26) that prevents backflow from the balloon (2) to the extracorporeal volume reservoir (9), and (iii) a nonflow-directing bypass throttle element (27) which allows a slow volume compensation between the balloon (2) and the extracorporeal volume reservoir (9), wherein the nonflow-directing throttle element (27) is arranged in parallel to the flow-directing one-way valve (26) as a bypass thereto, and wherein the regulating unit is implemented

• a) as a combined regulator and volume reservoir unit (3), where the extracorporeal volume reservoir (9) comprises a volume-expandable balloon bladder (28) made of a material with an elasticity sufficient to increase the volume due to an increasing pressure in order to provide a constant pressure or an appreciably constant pressure inside the extracorporeal volume reservoir (9), or
• b) as a weight or a spring element acting on the extracorporeal volume reservoir (9) with a constant pressure or an appreciably constant pressure.

A device for the sealing occlusion and/or for the space-filling tamponade of a hollow organ or a cavity in a human body, comprising a preferably fully and residually formed balloon (2) which is intended to be configured to apply an appreciably constant sealing pressure to a wall of the hollow organ or cavity to be occluded or tamponaded in use, comprising a regulating unit for a filling pressure within the interior of the balloon (2), which regulating unit is intended to be configured to be situated extracorporeally outside of the human body in use and comprises an extracorporeal volume reservoir (9) which is intended to be configured to be situated extracorporeally outside of the human body in use, and a feed line (6) for communicatively connecting the extracorporeal regulating unit to the interior of the balloon (2), wherein the connecting feed line (6) between the balloon (2) and the extracorporeal volume reservoir (9) comprises:

• a) a supply channel with a cross-sectional area corresponding to a circular cross-sectional area with a diameter of at least 2 mm,
• b) a flow-directing one-way valve (26) that prevents backflow from the balloon (2) to the extracorporeal volume reservoir of the regulator,
• c) a nonflow-directing throttle element (27) which allows a slow volume compensation between the balloon (2) and the extracorporeal volume reservoir,
• d) wherein the nonflow-directing throttle element (27) is arranged in parallel to the flow-directing one-way valve (26) as a bypass thereto, and wherein the regulating unit comprises:
• e) either a control apparatus for actively controlling the pressure in the extracorporeal volume reservoir (9) which is designed in such a way that the pressure in the balloon (2) is held constant, or
• f) a regulating apparatus for actively regulating the pressure in the extracorporeal volume reservoir (9) as a result of the pressure measured in the balloon (2) by a measuring sensor arranged inside of the balloon (2) for the purpose of specifying an actual value for a control loop that acts on the pressure in the extracorporeal volume reservoir (9).
