The invention relates to a pump device having a pump (8) and an energy supply device (5, 18), wherein the pump has a conveying element (9, 11) which conveys a fluid by means of supplied energy, wherein the pump has a transport state and an operating state, and wherein at least one first element (9, 9a, 10, 10′, 11) of the pump has a different shape and/or size in the transport state than in the operating state. The operating safety of such a pump device is increased by a detection device (12, 20, 21, 22, 23, 24, 25, 27, 28, 29) which detects whether at least the first element is in the operating state with respect to shape and/or size by means of a sensor.

An improved intravascular blood pump. Intravascular blood pumps using the present technology may be powered by an onboard motor unit configured to be located inside the patient's body, but which is separated from the pump unit by a flexible intermediate section housing a flexible drive shaft.

A method of constructing multiple conduits in building foundations that eliminates the process of core drilling after the foundation has been poured and set. This method creates optional openings for possible future connections. The process uses removable conduit molds installed before the foundation is poured. Once the foundation has set, conduit molds are removed to explose conduits in the foundation as needed.

The invention relates to a fluid pump having a housing delimiting a fluid chamber and having a conveying element for the fluid disposed in the fluid chamber, the housing, with respect to the shape and/or size thereof, being able to be changed between at least a first, expanded state and a second, compressed state. The object, to stabilise adequately a corresponding housing, is achieved according to the invention by the housing having at least one stabilisation chamber which can be supplied with a fluid pressure and is different from the fluid chamber, the first state of the housing being assigned to a first fluid pressure in the stabilisation chamber and the second state of the housing being assigned to a second fluid pressure.

A heart pump is disclosed herein. The heart pump can include a cannula having one or more outlets. An impeller can be positioned in the cannula. The impeller can be configured to pump blood through the outlets along a longitudinal axis when the impeller is rotated at an operational speed. The heart pump can be configured to adjust an effective area of the outlets while the impeller is rotating or to provide relative motion between the cannula and the impeller along the longitudinal axis while the impeller is rotating.

A controller for a blood pump, in particular a catheter-based intravascular blood pump, configured to utilize detected or determined aortic pressures and left ventricular pressures in order to calculate a coupling factor, which is then used to determine how to adjust the rotational speed of the blood pump, such as when the blood pump is used in conjunction with ECMO devices.

A minimally invasive circulatory support platform that utilizes an aortic stent pump or pumps. The platform uses a low profile catheter-based techniques and provides temporary and chronic circulatory support depending on the needs of the patient. Also described is a catheter-based temporary assist pump to treat patients with acute decompensated heart failure and provide circulatory support to subjects undergoing high risk percutaneous coronary intervention (“PCI”). Further described is a wirelessly powered circulatory assist pump for providing chronic circulatory support for heart failure patients. The platform and system are relatively easy to place, have higher flow rates than existing systems, and provide improvements in the patient's renal function.
