Abstract: A method for treating pleural effusion in a patient, the method comprising: providing a valve comprising: a body having a distal end, a proximal end and a lumen extending therebetween; an inlet disposed at the proximal end of the body, the inlet being fluidically connected to the lumen; an outlet disposed at the distal end of the body, the outlet being fluidically connected to the lumen; and at least one valve element disposed in the lumen of the body, the at least one valve element being a one-way valve element configured to permit the passage of fluid in a single direction through the lumen of the body; and implanting the valve in the body of the patient such that the inlet of the valve is fluidically connected to the pleural cavity of the patient, and such that the outlet of the valve is fluidically connected to a second body cavity.

Abstract: A valve for treating ascites, the valve comprising: a body having a distal end, a proximal end and a lumen extending therebetween; at least one valve element disposed in the lumen of the body, the at least one valve element being a one-way valve element configured to permit the passage of fluid in a single direction through the lumen of the body; and at least one connection element provided on at least one of the distal end and the proximal end of the body, wherein the at least one connection element is configured to connect the body of the valve to the side wall of a blood vessel.

Abstract: A vascular lock comprising a guide tube (1) and valve means (4) on the proximal end, these permitting the insertion of a catheter or instrument through the access lumen of the guide tube and into a vessel, is provided, in the region of the distal end of the guide tube, with balloon occlusion means (12) that comprise an occlusion balloon (13) which can be connected to a pressure medium source via a separate lumen in the guide tube such that said lumen can be alternately inflated and deflated. The vascular lock can be used for the non-drug blood pressure and perfusion modulation, e.g., by being introduced into the infrarenal aorta and by blocking or clearing the aorta as a function of the cardiac cycle.

Abstract: A system for occluding a blood vessel at a site of puncture of a blood vessel, especially after artery catheterization, comprises an oblong occlusive means (13) that has a shank (14) and a compression surface (15) configured thereon as the end face. The shank comprises a continuous bore (17) that extends through the compression surface to accommodate at least one guide means (11) inserted into the blood vessel and is, on the distal end (20) opposite the compression surface, adapted to be fixed on the patient on the skin when the compression surface is advanced towards the site of puncture (2).

Abstract: An aortic balloon occlusion cannula for the occlusion of the ascending aorta during cardiac surgery includes a cannula containing several lumina that are separated from one another. The cannula carries two dilatable occlusion balloons positioned at a distance from each other, one of the balloons being neighbored to the proximal end of the cannula which faces the heart and each of the balloons being connected to its own lumen which enables its dilation in independence from the other balloon. The cannula additionally contains at least one further lumen that is connected on the proximal side of the proximal occlusion balloon and on the distal side of the distal occlusion balloon to the lumen of the aorta and is adapted to be connected to an extracorporal blood supply device. A valve is assigned to the part of this additional lumen which ends on the proximal side of the proximal occlusion balloon.

Abstract: An aortic balloon occlusion cannula for the occlusion of the aorta ascendens during cardiac surgery including a cannula containing several lumina that are separated from one another. The cannula carriers two dilatable occlusion balloons positioned at a distance from each other, one of the balloons being neighbored to the distal end of the cannula which faces away from the heart and each of the balloons being connected to its own lumen which enables its dilation in independence from the other balloon. The cannula is insertable through the lefthand ventricle of the heart and through the valvula aortae and includes at least one further lumen. The further lumen being connected on the distal side, facing the body, of the distal occlusion balloon to the lumen of the aorta and is adapted to be connected to an extracorporal blood supply device. An additional separate lumen is provided in the cannula and forms a return conduit for liquid and opens on the proximal side of the proximal occlusion balloon.
