Abstract: Dialysis systems are disclosed comprising new fluid flow circuits. Systems may include blood and dialysate flow paths, where the dialysate flow path includes balancing, mixing, and/or directing circuits. Dialysate preparation may be decoupled from patient dialysis. Circuits may be defined within one or more cassettes. The fluid circuit fluid flow paths may be isolated from electrical components. A gas supply in fluid communication with the dialysate flow path and/or the dialyzer able to urge dialysate through the dialyzer and urge blood back to the patient may be included for certain emergency situations. Fluid handling devices, such as pumps, valves, and mixers that can be actuated using a control fluid may be included. Control fluid may be delivered by an external pump or other device, which may be detachable and/or generally rigid, optionally with a diaphragm dividing the device into first and second compartments.

Abstract: An implantable cardiovascular blood pump system is provided, suitable for use as a left ventricular assist device (LVAD) system, having an implantable cardiovascular pump, an extracorporeal battery and a controller coupled to the implantable pump, and a programmer selectively periodically coupled to the controller to configure and adjust operating parameters of the implantable cardiovascular pump. The implantable cardiovascular blood pump includes a coaxial inflow cannula and outflow cannula in fluid communication with one another and with a pumping mechanism. The pumping mechanism may be a vibrating membrane pump which may include a flexible membrane coupled to an electromagnetic actuator assembly that causes wavelike undulations to propagate along the flexible membrane to propel blood through the implantable cardiovascular pump. The implantable cardiovascular pump may be programmed to operate at frequencies and duty cycles that mimic physiologic flow rates and pulsatility while avoiding thrombus formation, hemolysis and/or platelet activation.

Abstract: The invention relates to a blade-type check valve for gaseous and liquid media, to be used in medical technologies as well as in waste water technology with at least three triangular blades, grouped in round configuration at the edges of a polygonal bore of a valve ring or housing, with the number of blades corresponding to the number of faces of the bore. At least at one of the three sides, the valve blades feature an integrated joint, which may also consist of fabric, whereas the two other sides of the valve blades form an articulated lock. The valve can be installed in any position and closes automatically, actuated by the backflow respectively return flow of the medium, without external energy.

Abstract: Embodiments of the present invention relate generally to certain types of reciprocating positive-displacement pumps (which may be referred to hereinafter as “pods,” “pump pods,” or “pod pumps”) used to pump fluids, such as a biological fluid (e.g., blood or peritoneal fluid), a therapeutic fluid (e.g., a medication solution), or a surfactant fluid. The pumps may be configured specifically to impart low shear forces and low turbulence on the fluid as the fluid is pumped from an inlet to an outlet. Such pumps may be particularly useful in pumping fluids that may be damaged by such shear forces (e.g., blood, and particularly heated blood, which is prone to hemolysis) or turbulence (e.g., surfectants or other fluids that may foam or otherwise be damaged or become unstable in the presence of turbulence).

Abstract: An improved valve leak detection system. The improved valve leak detection system comprises a membrane pump defining a flow path arranged to be opened and closed by at least one valve, a measuring device, a comparator, and a signal generator. The measuring device is configured to determine a conductivity value between two points on the flow path of the membrane pump, one point arranged upstream of the at least one valve and the other point arranged downstream of the at least one valve. The measuring device measures the conductivity value when the at least one valve is closed. The comparator is configured to continuously monitor the conductivity value. The signal generator is arranged to provide an output signal when the conductivity value is indicative of a valve leak condition for a set number of measurements within a set period of time.

Abstract: A tubular pulsatile ventricular assist device (PVAD) system for providing forward flow of blood in a pulsatile, peristaltic, and non-hemolytic manner to help reduce the amount of blood clotting associated with current ventricular devices on the market. The system can encircle a portion of a blood vessel, and the system can sequentially apply a pressure through each port in a particular pre-determined patter so as to selectively occlude the lumen, thereby creating a pulsatile, peristaltic movement along a length of system. Said movement causes blood to flow through the portion of the blood vessel.

Abstract: Inlet device and connecting devices for a minimally invasive miniaturized percutaneous mechanical circulatory support system. The inlet device includes an inlet portion and a transfer portion with a support structure. The inlet device can be used for transmitting a body fluid of a patient, for example blood, to an impeller of a pump of the circulatory support system. The connecting device can include a receiving element and an insertion element. The receiving element of the connecting device can include a receiving structure that the insertion element of the connecting device can be pushed into. The insertion element can include at least one slide-on ramp, the slide-on ramp being connectable to the receiving structure in a form-fitting, non-positive, force-locking, and/or self-locking manner. The inlet device can include a receiving element or an insertion element of the connecting device.

Abstract: An implantable pump includes a rigid housing with an oblate spheroid shape and having an inner chamber divided by a movable elastomeric membrane into a gas sub-chamber which is connectible through a drive line to an external pneumatic source, and a blood sub-chamber which is connectible through a graft assembly to an anatomical heart. The housing includes a blood port opening oriented at an angle and at the upper apex of the housing and connected to the blood sub-chamber, and a gas port opening to the gas sub-chamber that is situated at a lower apex of the housing. The pump is provided with a drive line that includes a gas conduit and a heart sensor, the drive line connectible to a drive system that is capable of delivering gas flow through the drive line gas conduit in response to signals driven by the heart sensor.
