Transcatheter system and method for regulating flow of fluid between two anatomical compartments

A transcatheter system comprising:

• a first device which is 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, wherein said connector comprises a neck for fluid passage from one anatomical compartment to another anatomical compartment;
• and
• a second device which is an intracorporeal flow regulating device for regulating the flow of fluid between said two anatomical compartments through said at least one anatomical wall wherein the flow regulating device comprises a pump, wherein the pump comprises a single pump housing, and wherein the single pump housing comprises a rotatable shaft supporting at least one blade located within the single pump housing, and
• complementary screwing means for detachably securing the intracorporeal flow regulating device to the intracorporeal connector, the screwing means located on an inner surface of the neck of the intracorporeal connector and an outer surface of an intermediate portion of the intracorporeal flow regulating device such that the intracorporeal flow regulating device is configured to be coupled to the intracorporeal connector when the intracorporeal flow regulating device and the intracorporeal connector are disposed across said at least one anatomical wall.
