Abstract

A template system for use in conjunction with a multiple reservoir or chambered implantable infusion pump is disclosed. The template system preferably includes at least one template having opening(s) for guiding a needle or syringe to various ports of the multiple reservoir pump. Preferably, each template includes at least two surfaces for cooperating with a like portions of the implantable pump, for properly seating the template on the pump. A kit is also disclosed including three templates for guiding injections into different ports of the pump.

Claims

1. A kit for use in refilling an implantable infusion pump having multiple ports, said kit comprising:

at least three different templates, each said template including at least one opening thereon,

wherein each of the templates allows the injection of fluid into a different port of said implantable infusion pump.

2. The kit according to claim 1, wherein said kit include three templates.

3. The kit according to claim 1, wherein each said template includes at least two seating surfaces corresponding to portions of said implantable infusion pump.

4. The kit according to claim 3, wherein the two seating surfaces and corresponding portions allow for proper alignment of said template with respect to said implantable infusion pump.

5. The kit according to claim 4, wherein said implantable infusion pump includes raised portions corresponding to recessed seating surfaces in said templates.

6. The kit according to claim 4, wherein said implantable infusion pump includes recessed portions corresponding to depending seating surfaces in said templates.

7. The kit according to claim 1, wherein said implantable infusion pump includes one recessed portion corresponding to one depending seating surface, and one raise portion corresponding to one recessed seating surface in said templates.

8. A template for use in refilling a multiple chamber implantable infusion pump, said template comprising:

a body having at least three openings thereon,

wherein said template allows the injection of fluid into at least a first and second chamber, and direct injection into a patient.

9. The template according to claim 8, wherein said template includes at least two seating surfaces corresponding to portions of said implantable infusion pump.

10. The kit according to claim 9, wherein the two seating surfaces and corresponding portions allow for proper alignment of said template with respect to said implantable infusion pump.

11. The kit according to claim 10, wherein said template includes recessed seating surfaces corresponding to raised portions of said implantable infusion pump.

12. The kit according to claim 10, wherein said template includes depending seating surfaces corresponding to recessed portions of said implantable infusion pump.

13. The template according to claim 8, wherein said template is constructed of material selected from the group consisting of polycarbonate, polypropylene, polyethylene and polyselphone.

14. A method of refilling an implantable infusion pump implanted in a patient, said method comprising the steps of:

placing a first template over a section of skin of the patient adjacent said pump, so as to align means on said first template with means on said implantable infusion pump;

injecting a needle through an opening formed in said first template, through the skin of the patient, and into a first port corresponding to a first chamber of said pump;

placing a second template over a section of skin of the patient adjacent said pump, so as to align means on said second template with means on said implantable infusion pump; and

injecting a needle through an opening formed in said second template, through the skin of the patient, and into a second port corresponding to a second chamber of said pump.

15. The method according to claim 14, further comprising the step of placing a third template over a section of skin of the patient, so as to align means said third template with means on said implantable infusion pump.

16. The method according to claim 15, further comprising the step of injecting a needle through an opening formed in said third template, through the skin of the patient, and into a third port of said pump, the third port allowing for direct injection into the patient.

17. The method according to claim 14, wherein said means on said first and second templates include recessed surfaces corresponding to raised portions of said pump.

18. The method according to claim 14, wherein said means on said first and second templates include protrusions corresponding to depression of said pump.

19. The method according to claim 14, wherein said means on said first and second templates include at least one surface corresponding to at least one portion of said pump and at least one protrusion corresponding to at least one depression of said pump.
