Abstract

In some examples, a lead identification system includes a first set of first lead indicators and a second set of second lead indicators. Each of the first lead indicators is configured to removably attach to at least one of a first therapy delivery element, a first epidural needle, or a first connector to uniquely identify at least one of the first therapy delivery element, the first epidural needle, or the first connector during implantation of the first therapy delivery element in the patient. Each of the second lead indicators is configured to removably attach to at least one of a second therapy delivery element, a second epidural needle, or a second connector to uniquely identify at least one of the second therapy delivery element, the second epidural needle, or the second connector during implantation of the second therapy delivery element in the patient.

First claim

What is claimed is:

1. A method, comprising:
inserting an epidural needle into a patient, the epidural needle having a stylet;
removing the stylet from the epidural needle;
inserting an implantable lead through the epidural needle, the implantable lead having a plurality of contacts;
positioning the implantable lead; and
attaching a removable lead indicator to the epidural needle.

2. The method of claim 1 , wherein the epidural needle has an elastomeric sleeve that is rotatable.

3. The method of claim 1 , further comprising:
attaching a proximal end of the implantable lead to a trial cable;
conducting a trial stimulation;
thereafter disconnecting the implantable lead from the trial cable;
removing the stylet from the implantable lead; and
inserting a lead indicator stylet in the proximal end of the implantable lead.

4. The method of claim 3 , further comprising:
removing the epidural needle; and
attaching the implantable lead to the patient with an anchor, the anchor having an indicator that corresponds with the removable lead indicator.

5. The method of claim 4 , further comprising:
tunneling a passageway to a site in the patient, the site being reserved for an implantable pulse generator;
passing the proximal end of the implantable lead through a tunneling sheath; and
removing the lead indicator stylet from the proximal end of the implantable lead.

6. The method of claim 5 , further comprising:
electrically coupling the proximal end of the implantable lead to a corresponding connector on the implantable pulse generator; and
implanting the implantable pulse generator in the site.

7. The method of claim 1 , wherein the implantable lead is a permanent lead.

8. The method of claim 1 , wherein the implantable lead is a trial lead.

9. The method of claim 1 , wherein the removable lead indicator is color-coded or has a plurality of identifying textures.

10. The method of claim 1 , wherein the removable lead indicator is releasably attachable to the epidural needle.

11. The method of claim 1 , wherein the removable lead indicator has an outer surface that includes a plurality of differently-sized recesses.

12. The method of claim 1 , further comprising: clipping, using a clip having an indicator that corresponds with the removable lead indicator, the implantable lead to the patient.

13. The method of claim 12 , wherein the clip includes a plurality of slots that are each configured to receive a proximal end of a respective implantable lead, and wherein the slots have different indicators.

14. The method of claim 1 , wherein the removable lead indicator is elastically deformable.

15. A method, comprising:
inserting an epidural needle into a patient, the epidural needle having a stylet;
removing the stylet from the epidural needle;
inserting an implantable lead through the epidural needle, the implantable lead having a plurality of contacts;
positioning the implantable lead;
attaching a removable lead indicator to the epidural needle;
clipping, using a clip having an indicator that corresponds with the removable lead indicator, the implantable lead to the patient;
attaching a proximal end of the implantable lead to a trial cable;
conducting a trial stimulation;
thereafter disconnecting the implantable lead from the trial cable;
removing the stylet from the implantable lead; and
inserting a lead indicator stylet in the proximal end of the implantable lead.

16. The method of claim 15 , further comprising:
removing the epidural needle;
attaching the implantable lead to the patient with an anchor, the anchor having an indicator that corresponds with the removable lead indicator;
tunneling a passageway to a site in the patient, the site being reserved for an implantable pulse generator;
passing the proximal end of the implantable lead through a tunneling sheath;
removing the lead indicator stylet from the proximal end of the implantable lead;
electrically coupling the proximal end of the implantable lead to a corresponding connector on the implantable pulse generator; and
implanting the implantable pulse generator in the site.

17. The method of claim 15 , wherein the epidural needle has an elastomeric sleeve that is rotatable, and wherein the removable lead indicator is elastically deformable.

18. The method of claim 15 , wherein the implantable lead is a permanent lead.

19. The method of claim 15 , wherein the removable lead indicator is color-coded, or has a plurality of identifying textures, or has an outer surface that includes a plurality of differently-sized recesses.

20. A method, comprising:
inserting an epidural needle into a patient, the epidural needle having a stylet, wherein the epidural needle has an elastomeric sleeve that is rotatable;
removing the stylet from the epidural needle;
inserting an implantable lead through the epidural needle, the implantable lead having a plurality of contacts;
positioning the implantable lead;
attaching a removable lead indicator to the epidural needle, wherein the removable lead indicator is color-coded, or has a plurality of identifying textures, or has an outer surface that includes a plurality of differently-sized recesses;
clipping, using a clip having an indicator that corresponds with the removable lead indicator, the implantable lead to the patient;
attaching a proximal end of the implantable lead to a trial cable;
conducting a trial stimulation;
thereafter disconnecting the implantable lead from the trial cable;
removing the stylet from the implantable lead; and
inserting a lead indicator stylet in the proximal end of the implantable lead
removing the epidural needle;
attaching the implantable lead to the patient with an anchor, the anchor having an indicator that corresponds with the removable lead indicator;
tunneling a passageway to a site in the patient, the site being reserved for an implantable pulse generator;
passing the proximal end of the implantable lead through a tunneling sheath;
removing the lead indicator stylet from the proximal end of the implantable lead;
electrically coupling the proximal end of the implantable lead to a corresponding connector on the implantable pulse generator; and
implanting the implantable pulse generator in the site.
