Abstract: A shoe may include an upper portion constructed from a continuous textile (e.g., a knit textile) that includes an elastic region and a structural region. The elastic region may be positioned about a perimeter of an opening into a cavity configured to receive a wearer's foot, and the elastic region may be configured to secure the shoe to a wearer's foot. The elastic region may have a first elasticity that is greater than a second elasticity of the structural region. In an unworn configuration, the elastic region may cause a tread surface of a sole of the shoe to have a continuous curvature. In a worn configuration, substantially all of an intermediate section of the tread surface may contact a surface on which the shoe is placed. The elastic region may improve the performance of the shoe, including the comfort and durability.

Abstract: A shoe may include an upper portion constructed from a continuous textile (e.g., a knit textile) that includes multiple regions having different textile properties to improve the performance of the shoe, including durability and comfort. In some cases, the multi-region upper portion may include regions having different thickness and/or flexibility based on a location relative to a wearer's foot to better support the wearer's foot. For example, the multi-region upper portion may include a reinforcement region having a first thickness and a flex region having a second thickness less than the first thickness. As another example, the multi-region upper portion may include a reinforcement region having a first stiffness and a flex region having a second stiffness less than the first stiffness.

Abstract: An implantable electrical stimulation lead includes a lead body, electrodes disposed along a distal end of the lead body, terminals disposed along the proximal end of the lead body, and conductors coupling the terminals to the electrodes. The electrodes include a tip electrode having an electrode body with an outer stimulating surface. An internal lumen is defined in the electrode body and extends inwardly from an opening in a proximal end of the electrode body. Side apertures are formed between the outer stimulating surface and the internal lumen. A portion of the lead body is disposed within the internal lumen and side apertures through the opening in the proximal end of the electrode body. That portion of the lead body facilitates retention of the tip electrode on a distal tip of the lead body.

Abstract: A lead with segmented electrodes can be made using one or two mold methods. In one method, segmented electrodes are individually disposed on pins on an interior surface within a mold. Each of the segmented electrodes has at least one opening formed in the exterior surface of the segmented electrode. The lead body is then molded between the electrodes. In a two mold method, segmented electrodes are inserted into electrode slots of a first mold and an interior portion of a lead body is formed. The resulting intermediate arrangement is placed into a second mold to form an exterior portion of the lead body. In another two mold method, a sacrificial ring is formed around the segmented electrodes in a first mold and the resulting intermediate structure is inserted in a second mold to form the lead body. The sacrificial ring is then removed.

Abstract: A method of making an electrical stimulation lead method includes attaching a pre-electrode to a lead body. The pre-electrode is a single, unitary, undifferentiated construct with a ring-shaped exterior. The method further includes attaching a plurality of conductor wires to the pre-electrode; and, after coupling to the lead body, removing an outer portion of the pre-electrode to separate remaining portions of the pre-electrode into a plurality of segmented electrodes spaced around the circumference of the lead body. When separated, each of the segmented electrodes includes a body and at least one leg extending inwardly from the body. The body defines an external stimulating surface and each of the at least one leg has an outer surface. For at least one of the at least one leg, the outer surface of the leg forms a non-perpendicular angle with the external stimulating surface of the body.

The electrode carrier includes a lattice region defining segmented electrode receiving openings. Each of the segmented electrodes extends around no more than 75% of a circumference of the lead and is disposed in a different one of the segmented electrode receiving openings of the electrode carrier.

Abstract: A stimulation lead includes a lead body. Terminals and electrodes are disposed along opposing end portions of the lead body and are electrically-coupled to one another via conductors. The electrodes include segmented electrodes. Each of the segmented electrodes includes a proximal end, a distal end, an exterior surface, an interior surface opposite the exterior surface, a first side-wall extending radially between the interior surface and the exterior surface from the distal end to the proximal end, and a second side-wall opposite to the first side-wall and extending radially between the interior surface and the exterior surface from the distal end to the proximal end. At least one of the segmented electrodes defines an open cavity that is formed along the first side-wall of the segmented electrode and that facilitates adhesion of the segmented electrode to the lead body.

In some instances, the pre-electrode includes at least one aperture extending into the body from the exterior surface and between two of the segmented electrodes with portions of the connecting material forming borders between the aperture and the proximal and distal ends of the pre-electrode.

Abstract: A method of forming a lead includes providing an elongated lead body defining an annular groove disposed around a circumference of the lead body along one of a distal end or a proximal end of the lead body.

An outer surface of the pre-contact body is ground down to form a contact disposed along the one of the distal end or the proximal end of the lead body.
