    Abstract: An implantable medical device delivery system includes a delivery catheter including an elongated body with a first portion defining a first lumen and a second portion defining a second lumen. An angle is defined between a first axis and a second axis defined by the first and second portions, respectively. The second axis points toward the left ventricular (LV) apex of the patient's heart when the first axis points into the CS. The first portion or an elongated element may extend into the CS to anchor the delivery catheter to the orientation of the CS.

    Abstract: A method and system for employing a medical device is disclosed. The medical device includes a housing, a processor disposed within the housing, a connector module, and a medical electrical epicardial lead connected to the processor through the connector module. The epicardial lead is used to sense a cardiac signal from tissue of a patient. The lead comprises an insulative lead body that includes a proximal end and a distal end, at least one conductor disposed in the lead body, and a side helical fixation member, disposed a distance from the distal end, the side helical fixation member. The side helical fixation member comprises a set of windings configured to wrap around the lead body circumference. The side helical fixation member includes a distal tip comprising a sharpened elongated flat free end that is perpendicular to the lead body and angled toward an inside of the set of windings.

    Abstract: A catheter assembly includes a cap and a spring-biased tethering member coupled thereto. The cap includes first and second portions, and a transition zone extending therebetween. A girth of the first portion is sized to fit within a distal-most opening of the catheter assembly; and a girth of the second portion tapers from a first size at the transition zone, which is too large to fit within the distal-most opening, to a smaller size at a distal end of the cap. The spring-biased tethering member holds the cap in open and closed positions, when the cap first portion extends within the distal-most opening, and when the cap is separated from the distal-most opening, respectively. At the closed position, the first portion is approximately concentric with the distal-most opening, and at the open position, an entirety of the cap is laterally offset from the distal-most opening.
