Method and apparatus for guiding an external needle to an implantable device
First Claim
1. A delivery system for delivery of a functional fluid from outside a patient to an implantable medical device inside the patient, the implantable medical device including a port that defines an insertion axis, the delivery system comprising:
- a supply assembly configured to contain the functional fluid and that selectively delivers the functional fluid to the implantable medical device, the supply assembly including a three dimensionally contoured outer surface, the supply assembly defining a supply axis;
a support tool that includes a main body and a removable member that is removably attached to the main body, an opening being included between the main body and the removable member, the opening receiving the supply assembly, the main body and the removable member cooperating to define a three dimensionally contoured nesting surface that conforms to and nests with the three dimensionally contoured outer surface of the supply assembly such that the supply axis remains aligned with and fixed relative to the insertion axis, the removable member being removable from the main body to allow the main body to be moved away from the patient while the supply assembly remains in a fixed position relative to the patient;
a tracking device that tracks a position and orientation of the support tool relative to the implantable medical device; and
a prophylactic member that is removably coupled to the support tool to be disposed between the support tool and the patient to reduce contamination of the support tool.

Abstract
A support tool for a supply assembly delivers a functional fluid to an implantable medical device. The supply assembly defines a supply axis. The support tool includes a support member defining an opening. The opening has a support axis, and the opening is configured to receive the supply assembly. The support member includes a three dimensionally contoured nesting surface that conforms to a corresponding three dimensionally contoured surface of the supply assembly. The corresponding surface of the supply assembly nests against the nesting surface to support the supply assembly such that the supply axis remains substantially fixed relative to and aligned with the support axis.

8. A delivery system for delivery of a functional fluid from outside a patient to an implantable medical device inside the patient, the implantable medical device including a port that defines an insertion axis, the delivery system comprising:
-
a supply assembly configured to contain the functional fluid and configured to selectively deliver the functional fluid to the implantable medical device, the supply assembly including a first nesting surface, the supply assembly defining a supply axis; a support tool separate from the implantable medical device and defining an opening configured to receive the supply assembly, the support tool defining a second nesting surface that conforms to and nests with the first nesting surface of the supply assembly such that the supply axis remains substantially aligned with the insertion axis; a tracking device that tracks a position and orientation of the separate support tool relative to the implantable medical device; and a prophylactic member that is removably positioned on the separate support tool to reduce contamination of the support tool. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20)

21. A delivery system for delivery of a functional fluid from outside a patient, the delivery system comprising:
-
an implantable medical device configured to be implanted inside the patient, the implantable medical device including a port that defines an insertion axis; a supply assembly configured to contain the functional fluid and configured to selectively deliver the functional fluid to the implantable medical device, the supply assembly including a first nesting surface and defining a supply axis; a support member having a main body and a removable member that is removably attached to the main body, the main body and the removable member including a second nesting surface that conforms to and nests with the first nesting surface and defining a bore passing through the support member along a support axis, the removable member configured to be removed from the main body to allow the main body to be moved away from the patient without removing the supply assembly from the patient; a tracking device configured to track the position of the supply axis relative to the port; and a prophylactic member that is removably positioned on the support member to reduce contamination of the support member. - View Dependent Claims (22, 23)
