The present invention relates to an implantable self-driven pump for use as a cavopulmonary assist device. The invention comprises an aortic turbine that uses some systemic blood from the left ventricle as an energy source and a venous pump that is coupled magnetically or mechanically to the turbine. The present invention more particularly relates to a cavopulmonary assist device (10) for a total cavopulmonary connection with superior vena cava-pulmonary artery anastomosis and inferior vena cava-pulmonary artery bridging via a conduit (9), said cavopulmonary assist device (10) comprising a pump unit (20) and a turbine unit (30) coupled by a shaft (401).

The present disclosure relates to a saccular cavopulmonary assist device, including a shell, an inflow tube (6) and an outflow tube (4), wherein a blood storage cavity (A) and a power cavity (B) are arranged in the shell, and the power cavity (B) is used for providing contraction and relaxation power for the blood storage cavity (A); the inflow tube (6) is arranged at a position corresponding to the power cavity (B) on the shell, an outer end is used for communicating with the vena cava, and an inner end communicates with the blood storage cavity (A) after passing through the power cavity (B); the outflow tube (4) is arranged at a position corresponding to the blood storage cavity (A) on the shell, an outer end is used for communicating with the pulmonary artery, and an inner end communicates with the blood storage cavity (A). This device can assist the cavopulmonary circulation of the single ventricle, realize repeated blood drawing and pumping actions, provide the required power for the pulmonary circulation of the patient, and restore the biventricular blood flow in the human body; and because the arrangement of the inflow tube in the power cavity, the internal structure of this device is more compact, the overall shape is smaller, and the energy of the power cavity can be fully utilized.

The present disclosure provides medical devices, systems and methods and in particular to devices and methods useful for anchoring graft materials to bodily structures.

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.

An implantable renal replacement therapy device may include: a first catheter configured to be inserted into a blood vessel in a subject's body; a pump in fluid communication with the first catheter, the pump is configured to pump subject's blood from the blood vessel; a filter in fluid communication with the pump, the filter is configured to: receive the subject's blood from the pump, and filter the received blood to provide a filtered blood and a filtrate liquid, wherein the filter is in fluid communication with the first catheter to cause an outflow of the filtered blood from the filter to the blood vessel; and a second catheter in fluid communication with the filter and configured to be inserted into an urinary bladder in the subject's body to cause an outflow of the filtrate liquid from the filter to the urinary bladder.

The present invention relates to a transcatheter method for providing fluid communication between two anatomical compartments. The present invention also relates to a transcatheter system comprising an intracorporeal connector for fluid communication between two anatomical compartments through at least one anatomical wall, wherein said connector is adapted to receive a flow regulating device, a connector, a flow regulating device and an insertion device.

An example pump for driving a biological fluid is described herein. The pump can include an inner tubular structure and an outer tubular structure arranged around the inner tubular structure. The outer tubular structure can be configured as an artificial muscle. The pump can also include a gel layer disposed between the inner and outer tubular structures.

Mechanical circulatory supports configured to operate in series with the native heart are disclosed. In an embodiment, an intravascular propeller is installed into the descending aorta and anchored within via an expandable anchoring mechanism. The propeller and anchoring mechanism may be foldable so as to be percutaneously deliverable to the aorta. The propeller may have foldable blades. The blades may be magnetic and may be driven by a concentric electromagnetic stator circumferentially outside the magnetic blades. The stator may be intravascular or may be configured to be installed around the outer circumference of the blood vessel. The support may create a pressure rise between about 20-50 mmHg, and maintain a flow rate of about 5 L/min. The support may have one or more pairs of contra-rotating propellers to modulate the tangential velocity of the blood flow. The support may have static pre-swirlers and or de-swirlers. The support may be optimized to replicate naturally occurring vortex formation within the descending aorta.
