Abstract
A medical device capacitor assembly can include a capacitor including a plurality of anodes and cathodes, wherein the capacitor has a first major face, a second major face opposite the first major face, and a third face extending between the first major face and the second major face. A first insulating film can be sized and shaped to assemble against the first major face, and can include a first set of flaps sized and shaped to cover at least a portion of the third face. A second insulating film sized and shaped to assemble against the second major face, and can include a second set of flaps sized and shaped to cover at least a portion of the third face.
Claims20
A medical device capacitor assembly, comprising:
- a capacitor including a plurality of anodes and cathodes, wherein the capacitor has a first major face, a second major face opposite the first major face, and a third face extending between the first major face and the second major face;
- a first insulating film sized and shaped to cover the first major face, and including a first set of flaps sized and shaped to cover at least a portion of the third face;
- and
- a second insulating film sized and shaped to cover the second major face, and including a second set of flaps sized and shaped to cover at least a portion of the third face.
An implantable medical device, comprising:
- an implantable medical device housing;
- a pulse generator circuit in the implantable medical device housing;
- a capacitor housing in the implantable medical device housing;
- a capacitor in the capacitor housing, the capacitor operatively coupled to the pulse generator circuit;
- and
- one or more insulating films extending over top and bottom portions of the capacitor, the one or more films including a first set of flaps extending down from the top portion over an edge portion of the capacitor and a second set of flaps extending up from the bottom portion over the edge portion, the first set of flaps and second set of flaps overlapping on the edge portion.
A method for insulating a stacked capacitor, comprising:
- coupling an inner portion of a first insulating film to a first major surface of the stacked capacitor;
- folding a first set of flaps of the first insulating film onto a perimeter portion of the stacked capacitor;
- coupling an inner portion of a second insulating film to a second major surface of the stacked capacitor;
- folding a second set of flaps of the second insulating film onto the perimeter portion of the stacked capacitor.
