Abstract

Partially implantable medical devices and methods associated with partially implantable medical devices.

Claims

1. A fluid and power cartridge, comprising:

a housing including at least one side wall and an end wall;

a needle extending from the end wall;

a power source carried by the housing; and

positive and negative power contacts associated with the housing and operably connected to the power source.

2. A fluid and power cartridge as claimed in claim 1, further comprising:

a bladder located within the housing.

3. A fluid and power cartridge as claimed in claim 2, wherein the housing side wall includes an aperture and an external protrusion that is located between the aperture and the end wall.

4. A fluid and power cartridge as claimed in claim 1, wherein the needle comprises a non-coring needle.

5. A fluid and power cartridge as claimed in claim 1, wherein the housing defines a longitudinal axis and the needle defines a longitudinal axis that is substantially coaxial with the housing longitudinal axis.

6. A fluid and power cartridge as claimed in claim 1, wherein the power source comprises a battery.

7. A fluid and power cartridge as claimed in claim 1, wherein

the at least one side wall comprises a substantially cylindrical side wall;

and

the positive power contact comprises an annular power contact.

8. A fluid and power cartridge as claimed in claim 7, wherein the positive power contact is carried by the end wall and is coaxial with the needle.

9. A fluid and power cartridge as claimed in claim 7, wherein

the negative power contact is carried by the cylindrical side wall.

10. A fluid and power cartridge as claimed in claim 1, wherein

the at least one side wall comprises a substantially cylindrical side wall;

and

the fluid and power cartridge includes a plurality of circumferentially spaced sensible members carried on the housing.

11. A fluid and power cartridge as claimed in claim 10, wherein

the positive power contact comprises an annular power contact associated with the end wall;

and

the plurality of circumferentially spaced sensible members are associated with the end wall and are radially offset from the annular power contact.

12. A fluid and power cartridge as claimed in claim 10, wherein the plurality of circumferentially spaced sensible members comprise a plurality of circumferentially spaced electrically conductive members separated by non-conductive regions.

13. A fluid and power cartridge as claimed in claim 1, further comprising:

a drug located with the housing.

14. A fluid and power cartridge for use with a partially implantable medical device including a power contact, the fluid and power cartridge comprising:

a housing including a side wall and an end wall;

a needle extending from the end wall; and

a power source carried by the housing; and

means for electrically connecting the power source to the medical device power contact.

15. A fluid and power cartridge as claimed in claim 14, further comprising:

a bladder located within the housing.

16. A fluid and power cartridge as claimed in claim 15, wherein the housing side wall includes an aperture and an external protrusion that is located between the aperture and the end wall.
