Abstract: Disclosed is a ventricular decompression and assisting apparatus (100). The apparatus (100) includes a pigtail and a catheter that is introduced percutaneously into a femoral/radial/brachial vein or artery and is advanced into the ventricle where blood is drawn and mechanically pumped back with an external blood pump (40) and pumped back downstream into the aorta (2) or venous system or the pulmonary artery using another suitable catheter from a second access into the femoral/radial/brachial artery or any vein and with tip thereof positioned at a desired location thus forming a ventricular vent loop. The desired cardiac circulation is maintained with smart pumping, monitoring and control while relieving the load on the heart muscle to rebuild strength thereof. The apparatus (100) provides user friendly simplified approach to ventricular venting and unloading as a means for mechanical circulatory support of the left heart, right heart or both circulations even simultaneously.

Abstract: So as to be able to determine the position of a functional element as precisely as possible during the invasive use of a blood pump in a patient's body without the use of imaging methods, the blood pump is connected to a main sensor which records signals of the patient's heart, which are compared to other electrophysiological heart signals recorded by several sensors distributed on the body surface so as to allow the position of the blood pump to be determined by way of linking.

Abstract: Apparatus and methods are described including a blood pump that includes an axial shaft, an impeller disposed on the axial shaft, a frame disposed around the impeller, and a motor disposed outside a subject's body, and configured to drive the impeller to pump blood from a distal end of the impeller to a proximal end of the impeller. A drive cable extends from outside the subject's body to the axial shaft, and is configured to impart rotational motion from the motor to the impeller by rotating. The drive cable is held in a preloaded state with respect to the frame, such that initiation of pumping of blood by rotation of the impeller does not cause the drive cable to axially elongate. Other applications are also described.

Abstract: In a method for intermittently occluding the coronary sinus, in which the coronary sinus is occluded using an occlusion device, the fluid pressure in the occluded coronary sinus is continuously measured and stored, the fluid pressure curve is determined as a function of time, and the occlusion of the coronary sinus is triggered and/or released as a function of at least one characteristic value derived from the measured pressure values. The pressure increase and/or pressure decrease per time unit each occurring at a heart beat are used as characteristic values.

Abstract: Apparatus and methods are described including a ventricular assist device that includes an impeller configured to be placed inside a subject's left ventricle. A frame is disposed around the impeller, the frame defining generally-cylindrical central portion, and a proximal conical portion that widens from a proximal end of the frame to a proximal end of the generally-cylindrical central portion. A motor drives the impeller to pump blood from the left ventricle to the subject's aorta, by rotation of the impeller. The impeller is configured to be disposed at least partially within the proximal conical portion of the frame during at least some of a time during which the impeller rotates. Other applications are also described.
