## Abstract

Molded headers, implantable signal generators having molded headers, and associated systems and methods are disclosed herein. An implantable signal generator in accordance with a particular embodiment includes a can having a shell and a battery positioned at least partially within the shell. An output terminal can be operably coupled to the battery and positioned to provide electrical power to a signal delivery device. A pre-molded header having a plurality of openings can be coupled to the can, and the output terminal can be positioned at least partially within an individual opening.

## Claims

### Claim 1

A method for forming an implantable signal generator, the method comprising:
providing a can;
positioning one or more can components in the can;
providing a header having multiple openings;
positioning multiple header components in respective ones of the multiple openings of the header, including:
two receiving elements each comprising multiple cylindrical contact assemblies; and
multiple parallel conductors each extending linearly between the can and a corresponding contact assembly;
aligning the header with the can; and
simultaneously establishing electrical connections between the multiple header components and the one or more can components via the conductors.

### Claim 2 (depends on 1)

The method of claim 1, wherein positioning one or more can components in the can includes positioning a battery in the can.

### Claim 3 (depends on 1)

The method of claim 1, wherein positioning multiple header components in respective ones of the multiple openings of the header includes inserting a charging coil at least partially within a corresponding one of the multiple openings.

### Claim 4 (depends on 3)

The method of claim 3, wherein the charging coil is shaped to at least partially match a rounded upper surface of the header.

### Claim 5 (depends on 3)

The method of claim 3, wherein positioning multiple header components in respective ones of the multiple openings of the header includes inserting a communication antenna at least partially within a corresponding one of the multiple openings.

### Claim 6 (depends on 1)

The method of claim 1, further comprising attaching a cover to the header to seal at least one of the multiple openings.

### Claim 7

A method for forming an implantable signal generator, the method comprising:
providing a can comprising a shell and a lid having multiple feed-throughs extending therethrough;
positioning one or more can components in the can;
providing a header having multiple openings;
positioning multiple header components in respective ones of the multiple openings of the header, including:
two receiving elements each comprising multiple cylindrical contact assemblies; and
multiple parallel conductors each extending linearly between the lid and a corresponding contact assembly;
aligning the header with the can; and
simultaneously engaging each conductor with a corresponding one of the multiple feed-throughs.

### Claim 8 (depends on 7)

The method of claim 7, wherein positioning multiple header components in respective ones of the multiple openings of the header includes inserting each of a charging coil and a communication antenna at least partially within a corresponding one of the multiple openings.

### Claim 9

A method for forming an implantable signal generator, the method comprising:
providing a can;
positioning one or more can components in the can;
molding a header including multiple header components encased at least partially within the header during the molding process, the header components including:
two receiving elements each comprising multiple cylindrical contact assemblies; and
multiple parallel conductors each extending linearly between the can and a corresponding contact assembly;
aligning the header with the can; and
simultaneously establishing electrical connections between the multiple header components and the one or more can components via the conductors.

### Claim 10 (depends on 9)

The method of claim 9, wherein the can comprises a shell and a lid having multiple feed-throughs extending therethrough.

### Claim 11 (depends on 10)

The method of claim 10, wherein simultaneously establishing electrical connections between the multiple header components and the one or more can components includes simultaneously engaging each conductor with a corresponding one of the multiple feed-throughs.

### Claim 12 (depends on 9)

The method of claim 9, wherein the multiple header components include a charging coil and a communication antenna.
