Abstract

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

Claims

1. An apparatus for use with a fluid cartridge, comprising:

a percutaneous port including an interior configured to receive the fluid cartridge;

an implantable operative portion including a fluid transfer device with an inlet and an outlet; and

a delivery/manifold tube including a manifold portion and a delivery portion, the manifold portion including a first fluid lumen that is operably connected to the fluid transfer device inlet, a second fluid lumen that is operably connected to the fluid transfer device outlet, and a lumen-free portion that prevents direct flow from first fluid lumen to the second fluid lumen, and the delivery portion including a delivery lumen that is operably connected to the second fluid lumen.

2. An apparatus as claimed in claim 1, wherein the percutaneous port includes a septum having a portion that is aligned with the first fluid lumen.

3. An apparatus as claimed in claim 1, wherein

the implantable operative portion includes a delivery/manifold tube receiver configured to receive the delivery/manifold tube and including an outlet port and an inlet port;

the delivery/manifold tube includes an outer surface, a first aperture that extends from the outer surface to the first fluid lumen, and a second aperture that extends from the outer surface to the second fluid lumen;

the delivery/manifold tube and the delivery/manifold tube receiver are respectively configured such that the first and second apertures will respectively be in fluid communication with outlet and inlet ports when the delivery/manifold tube is fully inserted into the delivery/manifold tube receiver.

4. An apparatus as claimed in claim 3, wherein the delivery/manifold tube includes a first annular channel that is aligned with the first aperture and a second annular channel that is aligned with the second aperture.

5. An apparatus as claimed in claim 4, wherein the delivery/manifold tube includes an external gasket carried by the lumen-free portion between the first and second annular channels.

6. An apparatus as claimed in claim 1, wherein the delivery/manifold tube defines a longitudinal axis and the first fluid lumen, the second fluid lumen and the delivery lumen are longitudinally aligned.

7. An apparatus as claimed in claim 1, wherein the implantable operative portion includes a housing with an aperture and the delivery portion extends through the housing aperture.

8. An apparatus as claimed in claim 1, wherein the percutaneous port includes an aperture configured to receive the delivery/manifold tube and a retainer having a locked state where the retainer prevents removal of the delivery/manifold tube from the aperture, and an unlocked state where the retainer does not prevent removal of the delivery/manifold tube from the aperture.

9. An apparatus as claimed in claim 1, wherein the percutaneous port includes an exterior having a porous region configured to promote soft tissue ingrowth.

10. An apparatus as claimed in claim 1, wherein the fluid transfer device comprises a pump.

11. An apparatus for use with a medical apparatus including a fluid transfer device, the apparatus comprising:

a manifold portion including an exterior surface, a first fluid lumen, a second fluid lumen, an outlet that extends though the exterior surface to the first fluid lumen, an inlet that extends though the exterior surface to the second fluid lumen, and a lumen-free portion that prevents direct flow from the first fluid lumen to the second fluid lumen; and

a delivery portion, which extends from the manifold portion, including a delivery lumen that is operably connected to the second fluid lumen.

12. An apparatus as claimed in claim 11, wherein the apparatus defines first and second longitudinal ends, the first fluid lumen extends to the first longitudinal end and the delivery lumen extends to the second longitudinal end.

13. An apparatus as claimed in claim 11, wherein the outlet comprises an aperture and the inlet comprises an aperture.

14. An apparatus as claimed in claim 13, wherein the manifold portion includes a first annular channel that is aligned with the outlet and a second annular channel that is aligned with the inlet.

15. An apparatus as claimed in claim 14, wherein the manifold portion includes an external gasket carried by the lumen-free portion between the first and second annular channels.

16. An apparatus as claimed in claim 11, wherein the apparatus defines a longitudinal axis and the first fluid lumen, the second fluid lumen and the delivery lumen are aligned with the longitudinal axis.
