Abstract

An access port, wherein the access port may include a body having an exterior surface and a chamber defined therein, a bore defined in the body providing fluid communication between the chamber and the exterior surface, a needle in fluid communication with the chamber, a passage defined in the body providing communication between the chamber and the exterior surface, a seal secured within the passage, and an actuator in communication with the needle, configured to move the needle relative to the passage or move the passage relative to the needle.

Claims

1. An access port system, comprising:

an implantable access port configured to be implanted into a subject, said access port including an access port body and an access port needle;

wherein said access port body is configured to collapse from an expanded position to a collapsed position to expose said needle outside said access port body and configured to expand from said collapsed position to said expanded position to contain said needle within said access port body; and

wherein said needle is arranged within said access port body to penetrate outwardly through skin of said subject from within said subject when said access port is implanted in said subject.

2. The access port system of claim 1, wherein said needle is coupled within said access port body to inhibit removal of said needle from said access port body.

3. The access port system of claim 2, wherein said needle is mechanically coupled within said access port body.

4. The access port system of claim 1, wherein said needle is fixed within said access port body.

5. The access port system of claim 1, wherein said needle is fixed to said access port body.

6. The access port system of claim 1, wherein said needle includes a replaceable needle tip.

7. The access port system of claim 1, wherein said access port body comprises a first portion and a second portion, and wherein at least one of said first portion and said second portion move relative to one another to collapse said access port body from said expanded position to said collapsed position and expand said access port body from said collapsed position to said expanded position.

8. The access port system of claim 7, wherein at least one of said first portion and said second portion slide relative to one another to collapse said access port body from said expanded position to said collapsed position and expand said access port body from said collapsed position to said expanded position.

9. The access port system of claim 1, wherein said access port includes at least one of a seal and a septum, and said needle is configured to extend through at least one of said seal and said septum.

10. The access port system of claim 1, wherein said access port includes at least one of a seal and a septum, and said needle is arranged within said access port body to extend through at least one of said seal and said septum when said access port body collapses from said expanded position to said collapsed position.

11. The access port system of claim 1, further comprising a catheter coupled to said access port.

12. The access port system of claim 1, wherein said access port body and said needle are configured such that said needle is completely containable within said access port body.

13. The access port system of claim 1, wherein said access port body and said needle are configured such that said needle is completely contained within said access port body when said access port body is in said expanded position.

14. The access port system of claim 1, further comprising an actuator configured to collapse said access port body to expose said needle outside said access port body and configured to expand said access port body to contain said needle within said access port body.

15. The access port system of claim 14, wherein said actuator is configured to collapse said access port body from said expanded position to said collapsed position.

16. The access port system of claim 14, wherein said actuator is configured to expand said access port body from said collapsed position to said expanded position.

17. The access port system of claim 14, wherein said access port includes said actuator.

18. The access port system of claim 14, wherein said actuator is at least partially contained within said access port body.

19. The access port system of claim 14, wherein said actuator is completely contained within said access port body.

20. The access port system of claim 14, wherein said actuator comprises a mechanical actuator.

21. The access port system of claim 20, wherein said mechanical actuator comprises a spring.

22. The access port system of claim 14, wherein said actuator comprises an electrical actuator.

23. The access port system of claim 22, wherein said electrical actuator comprises at least one of a motor, a linear traveler, a processor, a memory, a communication device, a transmitter, a receiver, a transceiver and a power supply.

24. The access port system of claim 14, wherein said actuator comprises a wireless electrical actuator which communicates wirelessly with said access port.

25. A method of introducing a composition into a subject, comprising:

collapsing an access port implanted within said subject, said access port containing a needle;

penetrating said needle outwardly through skin of said subject from within said subject while collapsing said access port implanted within said subject such that said needle is exposed outside said subject; and

introducing a composition into said access port through said needle when said needle is exposed outside said subject, and subsequently into said subject.

26. The method of claim 25 further comprising:

expanding said access port implanted within said subject;

withdrawing said needle inwardly through said skin of said subject from outside said subject while expanding said access port implanted within said subject such that said needle is concealed within said subject.

27. The method of claim 26 further comprising:

withdrawing said needle inwardly through said skin of said subject from outside said subject after said step of introducing said composition into said access port through said needle when said needle is exposed outside said subject, and subsequently into said subject.

28. The method of claim 25 wherein:

a catheter is coupled with said access port.

29. The method of claim 28 wherein:

said step of introducing a composition into said access port through said needle when said needle is exposed outside said subject, and subsequently into said subject further comprises introducing said composition into said access port through said needle when said needle is exposed outside said subject, through said catheter, and subsequently into said subject.

30. The method of claim 28 wherein:

said catheter is within a vein of said subject.

31. The method of claim 30 further comprising:

introducing said composition into said vein of said subject from said catheter.

32. The method of claim 30 wherein:

said vein is a jugular vein, a subclavian vein or a superior vena cava.

33. The method of claim 25 wherein:

said composition comprises at least one of blood, a pharmaceutical, a nutrient and a contrasting agent.
