Medical lead and manufacturing method therefor
First Claim
1. A method of manufacturing a medical lead comprising a lead body with at least one conductor and an elongate paddle having an electrode array, the method comprising:
- forming at least first, second, third and fourth substantially flat and elongate members, each member having first and second ends;
butt bonding the first end of the first member to the second end of the second member to form a first section with the junction of the first end of the first member and the second end of the second member constituting a first butt bond, the first section having first and second major surfaces;
butt bonding the first end of the third member to the second end of the fourth member to form a second section with the junction of the first end of the third member and the second end of the fourth member constituting a second butt bond, the second section having first and second major surfaces;
placing at least one electrode in the first section exposed through the first major surface of the first member, and placing at least one conductor in electrical communication with the electrode along the second major surface of the first member;
attaching the first major surface of the second section to the second major surface of the first section to form the elongate paddle of the medical lead with the first butt bond longitudinally offset from the second butt bond.

Abstract
A method of manufacturing a medical lead comprising a lead body with at least one conductor and an elongate paddle having an electrode array. A first section is formed having a first butt bond by butt bonding an end of a first substantially flat and elongate member to an end a second substantially flat and elongate member. A second section is formed having a second butt bond by butt bonding an end of a third substantially flat and elongate member to an end a fourth substantially flat and elongate member. The first section is laminated to the second section to form the elongate paddle of the medical lead with the first butt bond longitudinally offset from the second butt bond. A medical lead made by exemplary embodiments of the method is also described.

15. A medical lead for electrical stimulation or sensing, the medical lead comprising a generally flat paddle on the distal end of the lead body, the paddle having an electrode array comprising at least one electrode in electrical communication with the electrical conductor, the paddle being formed by a method comprising:
-
forming a first section having a first butt bond by butt bonding an end of a first substantially flat and elongate member to an end of a second substantially flat and elongate member, the first section having a first and a second major surface; forming a second section having a second butt bond by butt bonding an end of a third substantially flat and elongate member to an end of a fourth substantially flat and elongate member, the second section having a first and a second major surface; and laminating the first section to the second section to form the elongate paddle of the medical lead with the first butt bond longitudinally offset from the second butt bond. - View Dependent Claims (16, 17)

18. A method of manufacturing a medical lead comprising a lead body with at least one conductor and an elongate paddle having an electrode array, the method comprising:
-
forming at least first, second, third and fourth substantially flat and elongate members, each member having first and second ends; butt bonding the first end of the first member to the second end of the second member to form a first section with the junction of the first end of the first member and the second end of the second member constituting a first butt bond, the first section having first and second major surfaces; placing at least one electrode in the first section exposed through the first major surface of the first member, and placing at least one conductor in electrical communication with the electrode along the second major surface of the first member; attaching the third member to a first portion of the second major surface of the first section with the first end of the third member longitudinally offset from the first butt bond and leaving a second portion of the second major surface of the first section exposed; attaching the fourth member to the second portion of the second major surface of the first section and butt bonding the second end of the fourth member to the first end of the third member with the butt bond of the first end of the third member and the second end of the fourth member constituting a second butt bond, and thus forming the elongate paddle of the medical lead with the first butt bond longitudinally offset from the second butt bond. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27)
