First Claim
Patent Images
1. A method of refilling an implantable infusion pump implanted in a patient, said method comprising the steps of:
- providing a first template including first means for aligning with pump alignment means of said pump to ensure alignment of said first template with respect to said pump and a second template including second means for aligning with the pump alignment means to ensure alignment of said second template with respect to said pump, said first and second templates being separate from each other;
placing said first template over a section of skin of the patient adjacent said pump, so as to align said first means for aligning with said pump alignment means;
injecting a needle through an opening formed in said first template, through the skin of the patient, and into a first port of said pump;
placing said second template over a section of skin of the patient adjacent said pump, so as to align said second means for aligning with said pump alignment means; and
injecting a needle through an opening formed in said second template, through the skin of the patient, and into a second port of said pump.

11. A method of refilling an implantable infusion pump implanted in a patient, said method comprising the steps of:
-
placing a first template having a first opening, a first template structure, and a second template structure over a section of skin of the patient adjacent the pump, so as to align the first template structure with a first pump structure of the pump and to align the second template structure with a second pump structure of the pump, wherein the aligned template and pump structures ensure proper alignment of the first template with respect to the pump; injecting a needle through the opening of the first template, and into a first port of the pump; and placing a second template having a second opening, a third template structure, and a fourth template structure over a section of skin of the patient adjacent the pump, so as to align the third template structure with the first pump structure and to align the fourth template structure with the second pump structure, wherein the second template is separate from the first template and the aligned template and pump structures ensure proper alignment of the second template with respect to the pump; injecting a needle through the second opening of the second template, and into a second port of the pump, wherein the template structures are either recessed surfaces or raised portions and the corresponding pump structures are the other of recessed surfaces or raised portions. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
