Abstract: A medical lead for implantation includes an electrode assembly having a plurality of electrodes. Each of the plurality of electrodes include a plurality of electrode segments. Each electrode segment has a flexible conductor directly coupled to it. A strut is coupled within each of the plurality of electrodes such that each of the flexible conductors coupled to the plurality of electrode segments are supported between the strut and each of the plurality of electrodes by the strut. An insulator fills gaps between the plurality of electrodes, the strut and the flexible conductors.

Abstract: A medical lead includes a first wire coil having an outer diameter and a marker coil having an inner diameter. The marker coil is assembled over the first wire coil. The outer diameter first wire coil is smaller than the inner diameter of the marker coil thereby defining a gap. A second wire coil substantially fills the gap between the first wire coil and the marker coil. A ball weld is formed at an end of the medical lead adjacent each of the first and second wire coils and adjacent the marker coil.

Abstract: A method of forming a wire includes providing a first wire segment and a second wire segment. The first and second wire segments are inserted into opposite ends of a coupling segment. The coupling segment is laser welded such that the laser creates an indent in the coupling segment that penetrates into at least one of the first and second wire segments.

Abstract: A wire includes a first wire segment having an end portion and a second wire segment having an end portion. A coupling segment is adjacent the end portions of the first and second wire segments. The coupling segment is configured with a plurality of indents penetrating into at least one of the first and second wire segments.

Abstract: Embodiments of the present invention provide an internally threaded tube of virtually limitless length that can be easily and reliably constructed. In one aspect, the invention provides an internally threaded tube that includes a tube casing and a coil. A ratio of the length of the tube casing to the inner diameter of the tube casing can be greater than 5:1. The coil can be positioned coaxially within the tube casing. In this position, the coil can exert a radially outward force on the inner surface of the tube casing, which can aid in bonding. A portion of the coil can be specially adapted to be bonded to the tube casing. Methods of creating internally threaded tubes and methods of spirally delivering surgical components with internally threaded tubes are also disclosed.
