Abstract

A device for extending the length of the existing leads of an implantable device. The lead extenders are constructed and arranged for placement on the existing leads without removal thereof, significantly simplifying installation and obviating the need for contact with the organ connected to the distal ends of the leads. The lead extenders are provided at varying length to provide a physician with the most appropriate device for the particular application.

Claims

1. A lead extender for use with an implantable device system having a main lead of a predetermined length designed to be connected between a system electrode and an implantable device, the main lead having a device/lead connector on a proximal end to accommodate the connection to the implantable device, the lead extender comprising:

a lead extension made up of a connecting wire with a distal end and a proximal end, the lead extension having an insulating covering over the connecting wire;

a first connector attached to the distal end of the lead extension, the first connector configured to mate with the device/lead connector so as to allow easy connection between the main lead and the lead extension, the first connector also having a configuration capable of providing a secure connection; and

a second connector attached to the proximal end of the lead extension, the second connector being substantially identical to the device/lead connector to provide connection between the lead extension and the implantable device.

2. The lead extender of claim 1 wherein the first connector includes a set screw to provide a secure connection between the extension and the main lead.

3. The lead extender of claim 1 wherein the first connector includes a snap-fit structure to provide the secure connection between the first connector and the main lead.

4. The lead extender of claim 1 wherein the protective covering further extends a sufficient distance to cover the first connector when attached to the main lead.

5. The lead extender of claim 1 wherein the lead extension is of a predetermined length.

6. The lead extender of claim 1 wherein the first connector is a female type connector and the second connector is a male type connector.

7. A lead extender kit for use with an implantable device system, the implantable device system including a main lead for connection between an electrode and an implantable device, the main lead having a device/lead connector on a proximal end to accommodate the connection to the implantable device, the lead extender kit comprising:

a plurality of lead extensions, each lead extension having a varying length so as to be selectable to provide a desired extension length to the implantable device system, each lead extension further made up of a connecting wire with a distal end and a proximal end, each lead extension further having a first connector attached to the distal end of the lead extension, the first connector configured to mate with the device/lead connector so as to allow easy connection between the main lead and the main extension, the first connector also having a configuration capable of providing a secure connection and a second connector attached to the proximal end of the lead extension, the second connector being substantially identical to the device/lead connector to provide connection between the lead extension and the implantable device.

8. The lead extender kit of claim 7 wherein the varying lengths of the plurality lead extensions vary by a predetermined interval.

9. The lead extender kit of claim 8 wherein the predetermined interval is 5 centimeters.

10. The lead extender kit of claim 7 wherein the first connector of each lead extension includes a set screw to provide a secure connection between the extension and the main lead.

11. The lead extender kit of claim 7 wherein the first connector of each lead extension includes a snap-fit structure to provide the secure connection between the first connector and the main lead.

12. The lead extender kit of claim 7 wherein each lead extension further includes a protective covering to insulate the connecting wire, wherein the protective covering further extends a sufficient distance to cover the first connector.

13. The lead extender kit of claim 7 wherein the first connector of each lead extension is a female type connector and the second connector is a male type connector.

14. A method for easily extending the connection distance between an implantable device and an associated electrode, the method comprising;

selecting a lead extension of an appropriate length;

attaching the lead extension to an existing lead which is configured for attachment to the implantable device via a lead/device connection, wherein the lead extension made up of a connecting wire with a distal end and a proximal end and includes a first connector attached to the distal end of the lead extension, the first connector configured to mate with a lead/device connector on the existing lead so as to allow easy connection between the existing lead and the lead extension; and

attaching the lead extension to the implantable device using a second connector attached to the proximal end of the lead extension, the second connector being substantially identical to the device/lead connector to provide connection between the lead extension and the implantable device.

15. The method of claim 14 wherein the first connector further includes a set-screw device for providing the secure attachment, and wherein the method further comprised securing the connection via the set-screw device.

16. The method of claim 14 further comprising extending a protective covering which is provided on the lead extension so as to also cover the connection between the first connector and the existing lead.

17. A lead extender for use with an implantable device system, the implantable device system having a main lead of a predetermined length designed to be connected between a system electrode and an implantable device, the main lead having a device/lead connector on a proximal end to accommodate the connection to the implantable device, the lead extender comprising:

a lead extension made up of a connecting wire with a distal end and a proximal end, the lead extension having an insulating covering over the connecting wire;

a first connector attached to the distal end of the lead extension, the first connector configured to mate with the device/lead connector so as to allow easy connection between the main lead and the lead extension, wherein the insulating covering of the first connector has a length sufficient to also cover the first connector when attached to the main lead thus providing insulation to the connection; and

a second connector attached to the proximal end of the lead extension, the second connector being substantially identical to the device/lead connector to provide connection between the lead extension and the implantable device.

18. The lead extender of claim 17 wherein the first connector includes a set screw to provide a secure connection between the extension and the main lead.

19. The lead extender of claim 17 wherein the first connector includes a snap-fit structure to provide the secure connection between the first connector and the main lead.
