Methods and apparatuses for implanting and removing an electrical stimulation lead
First Claim
1. A lead introducer kit for preparing to implant an electrical stimulation lead for electrical stimulation of nerve tissue, comprising:
- a needle;
a guide wire;
a lead blank having a similar shape and size as an electrical stimulation lead to be inserted proximate the nerve tissue, the lead blank configured for insertion into the human body to determine whether the electrical stimulation lead may be inserted into position proximate nerve tissue to be stimulated; and
an introducer comprising an outer sheath and an inner penetrator, the outer sheath operable to be inserted into a human body near nerve tissue to be stimulated, the inner penetrator removably housed within the outer sheath and comprising an inner channel configured to accommodate the guide wire, the inner penetrator configured to be advanced along the guide wire to a desired location relative to the nerve tissue and removed from the outer sheath leaving the outer sheath substantially in position for insertion of the lead blank through the outer sheath to determine whether the electrical stimulation lead may be inserted into position proximate the nerve tissue to be stimulated.

Abstract
In one embodiment, a lead introducer kit for preparing to implant an electrical stimulation lead for electrical stimulation of nerve tissue is provided. The lead introducer kit includes a needle, a guide wire, a lead blank having a similar shape and size as an electrical stimulation, and an introducer. The lead blank is configured for insertion into the human body to determine whether the electrical stimulation lead may be inserted into position proximate nerve tissue to be stimulated. The introducer includes an inner penetrator removably housed within an outer sheath and including an inner channel configured to accommodate the guide wire. The inner penetrator is configured to be advanced along the guide wire to a desired location relative to the nerve tissue and removed from the outer sheath leaving the outer sheath in position for insertion of the lead blank to determine whether the electrical stimulation lead may be inserted into position proximate the nerve tissue to be stimulated.

12. A method of removing an electrical stimulation lead from a human body, comprising:
-
positioning a stimulation lead introducer over a body portion of an electrical stimulation lead that is at least partially implanted in a human body, the stimulation lead introducer including an outer sheath and an inner penetrator removably housed within the outer sheath and comprising an inner channel, a tip region of the inner penetrator extending out from the outer sheath, the stimulation lead introducer being positioned such that the body portion of the electrical stimulation lead is at least partially disposed within the inner channel of the inner penetrator;
advancing the stimulation lead introducer along the body portion of the electrical stimulation lead until the tip region of the inner penetrator is located adjacent a stimulating portion of the electrical stimulation lead;
advancing the outer sheath relative to the inner penetrator until the outer sheath covers at least a portion of the stimulating portion of the electrical stimulation lead; and
removing the outer sheath, the inner penetrator, and the electrical stimulation lead from the human body. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
