## Abstract

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.

## Claims

### Claim 1

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.

### Claim 2 (depends on 1)

The system according to claim 1, wherein the flow regulating device comprises an actuator to allow or prevent fluid flow through the intracorporeal connector.

### Claim 3 (depends on 1)

The system according to claim 1, wherein the flow regulating device comprises a first portion located in use in the first compartment, a second portion located in use in the second compartment, and an intermediate portion located in use through the anatomical wall(s).

### Claim 4 (depends on 3)

The system according to claim 3, wherein the first portion and/or the second portion comprises one or more apertures for fluid passage from the first compartment to the second compartment.

### Claim 5 (depends on 3)

The system according to claim 3, wherein the first portion comprises a cross-section of larger diameter than the diameter of the cross-section of the intermediate portion.

### Claim 6 (depends on 1)

The system according to claim 1, wherein when the flow regulating device is coupled to the connector, fluid can flow from the first compartment to the second compartment, and when the flow regulating device is not coupled to the connector, fluid is prevented from flowing from the first compartment to the second compartment.

### Claim 7 (depends on 1)

The system according to claim 1, wherein the pump comprises an inverted screw pump.

### Claim 8 (depends on 1)

The system according to claim 1, wherein the flow regulating device is adapted to receive a guide wire therethrough.

### Claim 9 (depends on 1)

The system according to claim 1, further comprising means for sealing the complementary screwing means.

### Claim 10 (depends on 1)

The system according to claim 1, wherein the connector comprises means for securing the neck across the anatomical wall.

### Claim 11 (depends on 10)

The system according to claim 10, wherein the securing means comprises an expandable anchor extending from a first end of the neck.

### Claim 12 (depends on 11)

The system according to claim 11, wherein, in its expanded state, the anchor lies substantially parallel to the anatomical wall of the second compartment.

### Claim 13 (depends on 10)

The system according to claim 10, wherein the connector comprises means for preventing tissue from hindering fluid passage through the neck.

### Claim 14 (depends on 13)

The system according to claim 13, wherein the prevention means comprises an expandable shield extending from a second end of the neck.

### Claim 15 (depends on 1)

The system according to claim 1, wherein the connector further comprises a gate to selectively prevent or allow passage of fluid from the first compartment to the second compartment.

### Claim 16 (depends on 15)

The system according to claim 15, wherein the gate is capable of allowing passage of fluid when the flow regulating device is received therethrough, and prevents passage of fluid in the absence of the flow regulating device.

### Claim 17 (depends on 1)

The system according to claim 1, wherein the connector is collapsible.
