Abstract: An implantable neurostimulation lead comprises a lead body having a distal end and a proximal end, and a lumen extending along a longitudinal axis between the distal and proximal ends. Multiple electrodes are provided proximate to the distal end of the lead body. The electrodes are configured to at least one of deliver stimulating pulses and sense electrical activity. A multi-layer coil is wound about the lumen and extends at least partially along a length of the lead body. The multi-layer coil includes a first winding formed with multiple winding turn segments wound about the lumen in a first direction about the longitudinal axis. The multilayer coil includes a second winding formed with multiple winding turn segments wound about the first winding in an opposite second direction about the longitudinal axis.

Abstract: An optical imaging system with a flexible cable having a first end and a second end. The cable has a central core element including a flexible optical conduit, with a number of wires surrounding the core element to form a tube concentric with an axis defined by the center of the core. The cable has a conductive shield layer surrounding the wires and uniformly spaced apart from the wires. An electronic instrument is connected to the first end of the cable and has an illuminator coupled with the optical conduit and a display device connected to the wires. An image transducer is connected to the second end of the cable and is connected to the wires. The wires may be twisted pairs evenly spaced apart from each other, and evenly spaced apart from an axis defined by the core.

Abstract: A medical imaging system with a base unit including an electronic display, and a remote imaging transducer connected to the display unit via a flexible cable. The cable includes a number of signal transmission lines, each of which includes a twisted pair of conductors for digital differential signal lines. Each conductor is connected at a first end to the transducer, and at a second end to the base unit. The signal transmission lines may be wrapped about a core, which may be an optical conduit communicating with a light source at the base unit.

Abstract: A cable includes a number of wires. Each of the wires has a number of signal conductors encompassed by a dielectric sheath, and the sheath is encompassed by a conductive shield. The wires are arranged side-by-side in a row at an end of each wire, where a termination element is connected. The termination element has opposed major faces, with an array of first contacts on a first face, and an array of second contacts on the opposed face, each of the first contact being electrically connected to a corresponding second contact. Each of the signal conductors of the wire elements is connected to a corresponding one of the first contacts. The signal conductors may be a pair of wires arranged in parallel, so that all signal conductors are in a common plane.

Abstract: A cable assembly has a central core element with a central conductor surrounded by an insulating core sheath having a uniform wall thickness. A plurality of twisted pairs of wires surround the core element, abutting each other and the core to form a tube concentric with an axis defined by the center of the core, a conductive shield layer surrounds the twisted pairs and is uniformly spaced apart therefrom.
