    摘要： Some examples of an electrical contact spring for an implantable medical device includes a housing, rigid and tubular in shape, defining a housing passage extending along a longitudinal axis, from a proximal portion including a proximal lip that defines a proximal opening, to a distal portion including a distal lip that defines a distal opening and a spring disposed in the housing, the spring tubular in shape and defining a spring passage concentric to the housing passage, the spring including: a distal ring portion disposed adjacent the distal portion of the housing and physically coupled to the housing, a plurality of spring elements coupled to and extending from the distal ring portion toward the proximal portion of the housing and a proximal ring portion disposed adjacent the proximal portion of the housing, cantilevered and suspended inside of and spaced apart from the housing by the plurality of spring elements.

    摘要： A single pass endocardial lead is provided which is adapted for implantation on or about the heart and for connection to a system for monitoring or stimulating cardiac activity. The lead includes a main body which extends into two distal leg portions, each having at least two electrodes coupled therewith. The first leg is for positioning within the ventricle of the heart. The second leg is for positioning within the atrium of the heart. Both the first leg and the second leg are bipolar and are adapted for positioning and fixation to the heart wall. The first and second legs can be fixated to the heart wall using either passive or active fixation structures. A movement assembly for advancing a helix comprises an externally threaded collar which engages with an internally threaded housing or housing insert.

    摘要： A method includes sandblasting an electrode surface, applying a conductive oxide precursor solution to the electrode surface, and heating the electrode for at least 5 minutes at a temperature between 350 degrees C. and 550 degrees C. to convert the precursor solution into an oxide coating. One method includes applying a composite material including a conductive component and a non-conductive component to an electrode and curing the composite material to form a coating on the electrode. One method includes providing a metallic oxide coating on an electrode surface and applying a galvanostatic treatment to the electrode to increase the effective surface area of the metallic oxide coating.
