Method for assembling components of a microstimulator
View Patent ↗An electrode assembly includes an electrode electrically connected to a capacitor with a wire. An assembly carrier may be used to hold and secure at least the wire and capacitor during assembly. A method of assembly for attaching a wire to a capacitor and an electrode may include an assembly carrier for housing and securing the wire, capacitor, and electrode during assembly.
1. A method for assembling components of a microstimulator, the method comprising:
passing a wire through a first microstimulator housing;
positioning an electronic assembly comprising a capacitor such that a long axis of the electronic assembly is perpendicular to the wire; and
bonding the capacitor to the wire.
2. The method of claim 1 , further comprising securing the first microstimulator housing and wire to limit movement of the wire during the bonding of the capacitor to the wire.
3. The method of claim 1 , further comprising:
bending the wire proximate to the bond such that the long axis of the electronic assembly is coincident to a long axis of the first microstimulator housing; and
at least partially inserting the electronic assembly within the first microstimulator housing.
4. The method of claim 3 , further comprising positioning a second microstimulator housing closed at one end over at least that part of the electronic assembly not already surrounded by the first microstimulator housing.
5. The method of claim 4 , further comprising:
applying a force along the long axis of the first microstimulator housing to maintain the first and second microstimulator housings in contact with each other; and
bonding the first and second microstimulator housings to each other.
6. The method of claim 5 , further comprising bonding the wire to a conductive electrode attached to the first microstimulator housing.
7. The method of claim 6 , wherein the bonding of the wire to the conductive electrode is performed after the bonding of the first and second microstimulator housings to each other.
8. The method of claim 5 , wherein bonding the first and second microstimulator housings to each other comprises rotating the first and second microstimulator housings around the long axis.
