## Abstract

An apparatus includes an implantable housing, a header mounted to the implantable housing and including a connector block cavity, and a connector block located within the connector block cavity, the connector block including a plastic housing portion, a coil spring, and a metallic termination member connected to the coil spring and exposed outside the plastic housing portion.

## Claims

### Claim at position 1

1-17. (canceled)

### Claim 18

A method comprising:
placing a plastic connector block housing portion into a connector block cavity of a header;
placing a coil spring into the connector block housing portion; and
connecting a metallic termination member to the coil spring and positioning the metallic termination member to be exposed outside the plastic housing portion.

### Claim 19 (depends on 18)

The method of claim 18, wherein the metallic termination member is non-circumferential around the coil spring.

### Claim 20 (depends on 18)

The method of claim 18, further including overmolding the header with an epoxy.

### Claim 21 (depends on 18)

The method of claim 18, wherein the metallic termination member is configured to electrically couple to a feedthrough that extends from a housing to the header, wherein the plastic connector block housing portion includes an outer surface with the metallic termination member lying flush against the outer surface.

### Claim 22 (depends on 18)

The method of claim 18, wherein the connector block cavity is open on a side of the header such that the connector block is side-mounted into the header.

### Claim 23 (depends on 18)

The method of claim 18, wherein the plastic housing portion includes a receiver section configured to receive at least a portion of the coil spring.

### Claim 24 (depends on 18)

The method of claim 18, wherein the plastic housing portion is integral to the header within the connector block cavity.

### Claim 25 (depends on 18)

The method of claim 18, wherein the plastic housing portion includes a discrete plastic housing body mounted within the connector block cavity.

### Claim 26 (depends on 18)

The method of claim 18, wherein the metallic termination member includes a flat ribbon connector.

### Claim 27 (depends on 18)

The method of claim 18, wherein the metallic termination member includes a metallic block including at least a portion configured to receive the coil spring.

### Claim 28 (depends on 18)

The method of claim 18, wherein the plastic housing portion includes a non-planar outer surface.

### Claim 29 (depends on 18)

The method of claim 18, wherein the metallic termination member includes a flat ribbon connector which extends away from the connector block and connected directly to a feedthrough.

### Claim 30

A method comprising:
placing a plastic connector block housing portion into a connector block cavity of a header of an implantable housing, the header including a plastic header core having a connector block cavity;
placing a coil spring into the connector block housing portion, the connector block including a plastic housing portion holding a spring and a metallic termination member connected to the spring and exposed outside the plastic housing portion, wherein the metallic termination member is configured to electrically couple to a feedthrough that extends from the implantable housing to the header, wherein the plastic connector block housing portion includes an outer surface with the metallic termination member lying flush against the outer surface; and
overmolding the header core with an epoxy to encapsulate the connector block and the header core.

### Claim 31 (depends on 30)

The method of claim 30, wherein the metallic termination member is non-circumferential around the spring.

### Claim 32 (depends on 30)

The method of claim 30, wherein the plastic housing portion includes a receiver section configured to receive at least a portion of the spring.

### Claim 33 (depends on 30)

The method of claim 30, wherein the plastic housing portion is integral to the header within the connector block cavity.

### Claim 34 (depends on 30)

The method of claim 30, wherein the plastic housing portion includes a discrete plastic housing body mounted within the connector block cavity.
