SYSTEM AND METHOD FOR IMPLANTING A PADDLE LEAD
First Claim
Patent Images
1. A system comprising:
- a tool having a body member defining a proximal end, a distal end, a lumen extending from the proximal end to the distal end, and a longitudinal slit in communication with the lumen and extending from the proximal end towards the distal end, the longitudinal slit havinga length;
a lead having(i) a proximal end including a contact for operably coupling the lead to an active electrical medical device, and(ii) a paddle-shaped distal end portion including an electrode electrically coupled to the contact, the paddle-shaped portion having a length; and
an introducer having a body member defining a proximal end, a distal end, and a lumen extending from the proximal end to the distal end,wherein the tool and lead are configured such that axial rotation of the tool relative to the lead when the paddle portion of the lead is received by the slit causes the paddle portion of be fully received by the lumen, andwherein the tool, the lead and the introducer are configured such that the paddle portion of the lead is advanceable distally through the lumen of the tool and into the lumen of the introducer when the lumens of the tool and the introducer are axially aligned.

Abstract
A method includes
- (i) inserting a paddle portion of a lead into a longitudinal slit of a tool having a lumen in communication with the slit;
- (ii) axially rotating the tool relative to the paddle portion of the lead to cause the paddle portion of the lead to enter the lumen;
- (iii) axially aligning the lumen of the tool with a lumen of an introducer; and
- (iv) advancing the paddle portion of the lead through the lumen of the tool and into the lumen of the introducer.

14. A method for applying an electrical signal to an occipital nerve of a patient, comprising:
-
positioning a distal end of an introducer in proximity to an occipital nerve of a patient, the introducer having a proximal end, the distal end, and a lumen extending from the proximal end to the distal end; inserting a paddle portion of a lead into a longitudinal slit of a tool having a lumen in communication with the slit; axially rotating the tool relative to the paddle portion of the lead to cause lumen of the tool to fully receive the paddle portion of the lead; axially aligning the lumen of the tool with a lumen of the introducer, advancing the paddle portion of the lead through the lumen of the tool and into the lumen of the introducer; distally advancing the paddle portion of the lead through the lumen of the introducer until the paddle portion of the lead is in proximity to the distal end of the introducer and the occipital nerve; withdrawing the introducer from the patient over the lead; and operably coupling the lead to an electrical signal generator such that a signal generated by the signal generator is deliverable to the occipital nerve via the paddle portion of the lead.

15. A method for implanting a lead having a distal paddle-shaped portion via an introducer, comprising:
-
bending the distal paddle-shaped portion of the lead; inserting the bent distal paddle-shaped portion of the lead into a lumen of an introducer.
-
-
16. A method comprising:
-
inserting a paddle portion of a lead into a longitudinal slit of an introducer, axially rotating the introducer to cause the paddle portion of the lead to enter a lumen of the introducer, the lumen being in communication with the longitudinal slit.
