Abstract

Claims (43)

1. A method, comprising the steps of:

communicating with an implanted infusion device that includes first and second reservoir compartments, a first fluid transfer device operably connected to at least one of the first and second reservoir compartments, first and second fill ports respectively operably connected to the first and second reservoir compartments, and first and second needle detectors respectively associated with the first and second fill ports;

instructing the implanted infusion device to actuate the first and second needle detectors;

receiving needle detection data;

presenting an indication of the amount of time that the needle detectors will remain actuated; and

in response to a needle being detected by one of the first and second needle detectors, providing an indication as to which fill port the needle is located in.

2. A method as claimed in claim 1 , wherein the step of providing an indication comprises displaying fill port and/or reservoir information associated with the fill port that the needle is located in.

3. A method as claimed in claim 2 , wherein the information includes infusible substance information.

4. A method as claimed in claim 1 , wherein the first fluid transfer device is operably connected to the first reservoir compartment and the implantable infusion device includes a second fluid transfer device operably connected to the second reservoir compartment.

5. An implantable infusion device, comprising:

an infusion device housing;

a header carried by the infusion device housing;

first and second reservoir compartments associated with the infusion device housing;

a first fluid transfer device operably connected to at least one of the first and second reservoir compartments;

first and second fill ports associated with the infusion device housing and respectively operably connected to the first and second reservoir compartments; and

wherein the infusion device housing includes a first palpable landmark adjacent to the first fill port, and the first palpable landmark is located in spaced relation to the header;

wherein the infusion device housing defines a generally curved perimeter; and

wherein the first palpable landmark comprises a discontinuity in the generally curved perimeter.

6. An implantable infusion device as claimed in claim 5 , wherein the infusion device housing includes a second palpable landmark adjacent to the second fill port.

7. An implantable infusion device as claimed in claim 6 , wherein the first and second palpable landmarks face in different directions.

8. An implantable infusion device as claimed in claim 5 , wherein the discontinuity comprises an indentation in the generally curved perimeter.

9. An implantable infusion device as claimed in claim 5 , further comprising:

first and second needle detectors respectively associated with the first and second fill ports.

10. An implantable infusion device as claimed in claim 5 , wherein the first fluid transfer device is operably connected to the first reservoir compartment, the implantable infusion device further comprising:

a second fluid transfer device operably connected to the second reservoir compartment.

11. An implantable infusion device as claimed in claim 10 , further comprising:

a first delivery lumen operably connected to the first fluid transfer device; and

a second delivery lumen operably connected to the second fluid transfer device.

12. An implantable infusion device as claimed in claim 11 , wherein the first and second delivery lumens are located within a single catheter.

13. An implantable infusion device as claimed in claim 5 , further comprising:

a reservoir and a pressure transmissive partition located within the reservoir, the first and second reservoir compartments being located within the reservoir on opposite sides of the pressure transmissive partition.

14. An implantable infusion device, comprising:

an infusion device housing having a curved outer perimeter and a first palpable landmark that defines a discontinuity in the curved outer perimeter;

first and second reservoir compartments associated with the infusion device housing;

a first fluid transfer device operably connected to at least one of the first and second reservoir compartments; and

first and second fill ports associated with the infusion device housing and respectively connected to the first and second reservoir compartments such that fluid passing through the first fill port enters the first reservoir and fluid passing through the second fill port enters the second reservoir;

wherein the first fill port is located on the first palpable landmark.

15. A method, comprising the steps of:

communicating with an implanted infusion device that includes first and second reservoir compartments, a first fluid transfer device operably connected to at least one of the first and second reservoir compartments, first and second fill ports respectively operably connected to the first and second reservoir compartments, and first and second needle detectors respectively associated with the first and second fill ports;

instructing the implanted infusion device to actuate the first and second needle detectors;

receiving needle detection data; and

in response to a needle being detected by one of the first and second needle detectors, displaying fill port information associated with the fill port that the needle is located in and displaying the name of the infusible substance stored in the reservoir that is connected to the fill port that the needle is located in.

16. A method as claimed in claim 15 , wherein the first fluid transfer device is operably connected to the first reservoir compartment and the implantable infusion device includes a second fluid transfer device operably connected to the second reservoir compartment.
