Abstract: A method of forming a medical device lead connection element is described. The method includes positioning an end portion of a lead filar to overlap a lead end connection element such that the positioning creates mutual interference between the lead filar and the lead end connection element, and forming an interference configuration. Then melting the end portion of the lead filar to form a weld joint and allowint the end portion of the lead filar to move towards the end connection element.

Abstract: An implantable segmented electrode structure may be configured to conduct electrical signals between elongated conductors of an implantable medical lead and respective portions of tissue of a patient. The implantable medical lead may extend from an implantable medical device that is implanted within the patient. The segmented electrode structure includes a plurality of separate electrode surfaces. The electrode surfaces are at a plurality of different axial positions and angular positions within the implantable segmented electrode structure. The segmented electrode structure additionally includes a plurality of prongs. The prongs extend axially from a proximal end of the segmented electrode structure through the segmented electrode structure. Each prong may electrically connect to one of the electrode surfaces. The prongs may terminate distally at respective electrode surfaces. Each prong may be configured to electrically connect to one of the elongated conductors.

Abstract: A medical device lead connection assembly includes an end connector element including a plurality of fixed connection element tabs extending from the end connector element to a tab distal end. A lead body includes a plurality of lead filars extending through the lead body and coupled to a corresponding fixed connection tab. A tubular guide hub extends from a hub proximal end to a hub distal end. The tubular guide hub includes a plurality of guide elements circumferentially disposed about an outer surface of the guide hub. The hub distal end is disposed within the lead body and the hub proximal end received within connection element tabs, and selected guide elements contact selected lead filars.

Abstract: A medical device lead assembly includes an end connector element having a plurality of fixed connection element tabs each respectively extending from the end connector element to a tab distal end, and a lead body having a plurality of lead filars extending through the lead body and forming a filar coil. Each of the plurality of lead filars is coupled to a corresponding fixed connection tab. Each of the plurality of lead filars have a diameter of less than 150 micrometers or less than 125 micrometers, or from 50 to 125 micrometers or from 50 to 100 micrometers. The filar coil having an outer diameter value being less than 1.5 mm and a first pitch within the lead body and a second pitch adjacent to the end connector element and the second pitch is greater than the first pitch.
