Abstract

Various embodiments of the present invention provide a conduit system including an outer lumen, an inner lumen, and an attaching device. In other embodiments, a multiple access port device adapted for communication with at least one of an outer lumen, an inner lumen, or an attaching device of a conduit system is provided. In yet other embodiments, a system including an inner lumen that is collapsible is provided. Means for closing a conduit system are also provided, including a plug for insertion through an attaching device and a variable radius coiled member associated with an attaching device.

Claims

1. A device for attaching to a tissue wall having a first surface and a second surface, the device comprising:

a port defining an opening extending along a longitudinal axis of the device;

a plurality of coils fixedly attached to the port and configured for advancing at least partially through the tissue wall such that at least a portion of each coil becomes disposed between the first surface and the second surface of the tissue wall, wherein the coils are centered on a common rotational axis; and

a plug configured for releasably attaching to the port and for positioning at least partially within the opening of the port, wherein the plug comprises a valve configured for moving between a closed state and an open state to control fluid flow through the plug.

2. The device of claim 1, wherein the opening of the port extends from a proximal end to a distal end of the port in a direction of the longitudinal axis of the device.

3. The device of claim 2, wherein the coils each extend distally beyond the distal end of the port.

4. The device of claim 1, wherein the common rotational axis of the coils is coaxial with the longitudinal axis of the device.

5. The device of claim 1, wherein the coils each have a radially expanding helical shape.

6. The device of claim 1, further comprising a flange extending about the port and configured for engaging the tissue wall.

7. The device of claim 1, wherein the closed state is a natural state of the valve.

8. The device of claim 7, wherein the valve is configured for moving from the closed state to the open state upon insertion of an instrument through the valve.

9. The device of claim 1, further comprising a tube configured for advancing at least partially through the opening of the port.

10. The device of claim 9, wherein the tube comprises a valve configured for controlling fluid flow through the tube.

11. The device of claim 1, wherein the valve is positioned at a distal end of the plug.

12. The device of claim 1, wherein the valve comprises a plurality of separable portions configured for moving apart from one another when the valve is moved from the closed state to the open state.

13. The device of claim 1, wherein the plug comprises threads configured for releasably engaging mating threads of the port.

14. The device of claim 1, wherein the plug comprises a distal end, and wherein the distal end of the plug is configured for positioning within the opening of the port when the plug is attached to the port.

15. The device of claim 1, wherein the plug comprises a distal end, and wherein the distal end of the plug is configured for positioning distally beyond a distal end of the port when the plug is attached to the port.

16. The device of claim 1, wherein the plug comprises a proximal portion having a first outer diameter and a distal portion having a second outer diameter, and wherein the first outer diameter is greater than the second outer diameter.

17. The device of claim 16, wherein the proximal portion of the plug is configured for positioning at least partially within the opening of the port when the plug is attached to the port.

18. The device of claim 17, wherein the distal portion of the plug is configured for positioning at least partially outside of the opening of the port when the plug is attached to the port.

19. The device of claim 16, wherein the valve is positioned along the distal portion of the plug.

20. The device of claim 16, wherein the distal portion of the plug is configured for positioning at least partially through the tissue wall between the first surface and the second surface of the tissue wall.
