Abstract

Medical devices and related methods enable physicians and/or other medical personnel to access percutaneously the interior of a patient. One particular device includes a housing which defines a cavity, a first opening into the cavity, and a second opening into the cavity. The housing is implantable in a patient. The cavity is placed subcutaneously within the patient. The first opening is substantially flush with the surface of the skin of the patient and creates a percutaneous passageway from the exterior of the skin of the patient into the cavity, and the second opening creates a passageway from the cavity into the interior of the patient. A connector is coupled to the second opening and disposed substantially within the cavity to enable a connection between a first device and a second device disposed within the interior of the patient.

Claims

1. A medical device, comprising;

a housing defining a cavity, a first opening into the cavity, and a second opening into the cavity, the housing being implantable in a patient to dispose the cavity subcutaneously within the patient, the first opening being substantially flush with the surface of the skin of the patient and creating a percutaneous passageway from the exterior of the skin of the patient into the cavity, the second opening creating a passageway from the cavity into the interior of the patient; and

a connector coupled to the second opening and disposed substantially within the cavity, the connector for allowing a connection between a first device and a second device disposed within the interior of the patient.

2. The medical device of claim 1 further comprising a cover removably couplable to the housing to selectively seal and expose the first opening, the cover being substantially coplanar with the surface of the skin of the patient when sealing the first opening and being removable to allow the first and second devices to be connected via the connector.

3. The medical device of claim 1 wherein the connector comprises a luer connector.

4. The medical device of claim 1 wherein the first device comprises a connection tube and the second device comprises a catheter.

5. The medical device of claim 1 wherein the housing defines a flange for extending subcutaneously into the patient to anchor the housing in the patient.

6. The medical device of claim 3 further comprises a valve.

7. The medical device of claim 3 further comprising a cap removably coupled to the luer connector to selectively seal and expose the luer connector.

8. The medical device of claim 6 wherein the cap removably couples to the luer connector with a threaded connection.

9. The medical device of claim 4 wherein the catheter comprises a single lumen catheter.

10. The medical device of claim 4 wherein the catheter comprises a multilumen catheter.

11. The medical device of claim 3 wherein the luer connector is telescopic and capable of being extended out of the cavity when the cover is removed from the first opening.

12. The medical device of claim 2 wherein the cover comprises a locking mechanism to prevent the cover from being inadvertently removed.

13. The medical device of claim 1 wherein the first device comprises an infusion device for infusing medication into the patient.

14. The medical device of claim 1 wherein the first device comprises a device for removing bodily fluids of the patient.

15. The medical device of claim 1 wherein the first device comprises a device for removing, purifying, and reintroducing blood into the patient.

16. The medical device of claim 1 wherein the housing comprises a canoe shape.

17. The medical device of claim 1 wherein the housing comprises an elliptical shape.

18. The medical device of claim 3 wherein the luer connector comprises a pivoting luer connector opening a fluid path through the second opening when pivoted to a first position and sealing the fluid path through the second opening when pivoted to a second position.

19. The medical device of claim 1 wherein the connector comprises an electrical connector.

20. The medical device of claim 19 wherein the electrical connector is releasably couplable to a battery disposable entirely within the cavity for supplying power to the second device.

21. The medical device of claim 19 wherein the electrical connector is releasably couplable to a control device disposable entirely within the cavity for supplying control signals to the second device.

22. The medical device of claim 1 wherein the connector is releasably couplable to the second opening.

23. The medical device of claim 1 wherein the connector comprises an electrical connector.

24. The medical device of claim 2 wherein the cover further comprises an electrical connector.

25. The medical device of claim 2 wherein the cover further comprises a display.
