A cardiac assist system includes a pneumatic effector which is implanted beneath a pericardial sac and over a myocardial surface overlying the patient's left ventricle. A port is implanted and receives a percutaneously introduced cannula. The port is connected to supply a driving gas received from the cannula to the pneumatic effector. An external drive unit includes a pump assembly and control circuitry which operate the pump to actuate the pneumatic effector in response to the patient's sensed heart rhythm. A connecting tube has a pump end connected to the pump and a percutaneous port-connecting end attached to the implantable port.

A device to assist the performance of a heart with at least one pump that is formed as a rotary pump and driven via a magneto coupling.

The present invention helps in enabling cardiac recovery in patients with heart failure and for facilitating cardiac muscle regeneration by long term augmentation of the coronary perfusion pressure and thereby the coronary blood flow by using an implantable, preferably self-contained electrically operated pump which takes the oxygen rich blood from one of the chambers of the heart or a large blood vessel, that include the aorta, the subclavian artery, left atrium, one or more pulmonary veins, etc and pumps it into a singular or multitude of coronary arteries through a natural (autologous, homologous or heterologous) or synthetic conduit, a medium to long term inotropic support to the heart, through a dedicated channel to deliver inotropic and other medicines and stem cells directly into the coronary circulation, where one end of the channel typically ends outside the body and the other end rests inside the lumen of the conduit which supplies the oxygenated blood into the coronary arteries; a central processing unit (CPU) with an integrated defibrillator to monitor and control pump speed and flow rates; an implantable power source for the pump which can be charged transcutaneously using an external wireless system (TET: transcutaneous energy transfer systems), to power the pump and the CPU.

A catheter for intravascular use has a blood inlet and a blood outlet, and includes a membrane arranged in the catheter in such a way that at least one part of the blood flowing into the catheter via the blood inlet during operation comes into contact with the membrane. The membrane allows an exchange of at least one substance between a carrier medium and the blood. The carrier medium is a carrier fluid in which the substance to be exchanged can be dissolved, and the catheter includes a delivery device that is designed to at least partially compensate for a pressure difference between the blood inlet and the blood outlet during operation. A method for removing at least one substance from venous blood for diagnostic purposes uses a device of this type.
