1. An implantable paddle lead comprising:
- an elongated lead body with a proximal end and a distal end;
a plurality of terminals disposed at the proximal end of the lead body;
a paddle body coupled to the distal end of the lead body, the paddle body having a length, a width, and front surface, the paddle body disposed in a flat configuration;
a plurality of contacts disposed on the front surface of the paddle body;
at least one manually-bent, adjustable shape-retaining member interconnected with the paddle body, the at least one shape-retaining member formed from a deformable material, wherein the at least one shape-retaining member is interconnected with the paddle body such that bending the at least one shape-retaining member into a bent configuration causes the paddle body to bend from the flat configuration into a corresponding bent configuration, wherein the paddle lead is configured and arranged for implantation into a patient with the paddle body disposed in the bent configuration, wherein the plurality of contacts are configured and arranged to stimulate patient tissue while the paddle body is disposed in the bent configuration, wherein the at least one shape-retaining member is stiff enough to maintain the same bent configuration of the at least one paddle body for at least one day after implantation of the paddle lead, and wherein the bent configuration that the at least one shape-retaining member is configured and arranged for bending the paddle body into prior to implantation of the paddle lead into the patient corresponds to a shape of a portion of an anatomical structure disposed at, or in proximity to, a target stimulation region within the patient; and
a plurality of conductors, each conductor electrically coupling at least one of the contacts to at least one of the terminals.

Abstract
An implantable paddle lead includes a paddle body coupled to a distal end of an elongated lead body. A plurality of contacts are disposed on a front surface of the paddle body. At least one manually bendable shape-retaining member is interconnected with the paddle body. The at least one shape-retaining member is formed from a deformable material that is stiff enough to maintain a given shape for at least one day. The at least one bendable shape-retaining member is interconnected with the paddle body such that bending the at least one shape-retaining member causes a corresponding bend of at least a portion of the paddle body in proximity to the at least one shape-retaining member.

14. A method for implanting a paddle lead into a patient, the method comprising:
-
providing an implantable paddle lead comprising an elongated lead body with a proximal end and a distal end; a plurality of terminals disposed at the proximal end of the lead body; a paddle body coupled to the distal end of the lead body, the paddle body having a length, a width, and front surface, the paddle body disposed in a flat configuration; a plurality of contacts disposed on the front surface of the paddle body; at least one manually-bent, adjustable shape-retaining member interconnected with the paddle body, the at least one shape-retaining member formed from a deformable material, wherein the at least one shape-retaining member is interconnected with the paddle body such that bending the at least one shape-retaining member into a bent configuration causes the paddle body to bend from the flat configuration into a corresponding bent configuration, wherein the paddle lead is configured and arranged for implantation into a patient with the paddle body disposed in the bent configuration, wherein the plurality of contacts are configured and arranged to stimulate patient tissue while the paddle body is disposed in the bent configuration, and wherein the at least one shape-retaining member is stiff enough to maintain the same bent configuration of the at least one paddle body for at least one day after implantation of the paddle lead; and a plurality of conductors, each conductor electrically coupling at least one of the contacts to at least one of the terminals; bending the at least one shape-retaining member of the paddle lead, wherein bending the at least one shape-retaining member causes the paddle body of the paddle lead to bend from the flat configuration into a bent configuration that conforms to at least a portion of an internal anatomical structure of the patient; inserting the paddle lead, with the paddle body disposed in the bent configuration, into the patient such that at least a portion of the paddle body abuts the anatomical structure; and electrically stimulating the anatomical structure using at least one of the plurality of contacts while the paddle body is disposed in the bent configuration; wherein the at least one shape-retaining member is stiff enough to maintain the paddle body in the same bent configuration for at least one day. - View Dependent Claims (15, 16, 17, 18, 19)
