    Abstract: An adapter configured to electrically connect a test device to an implantable medical lead comprises a rotational electrical coupling. The rotational electrical coupling is configured to electrically connect a lead electrical connector to an adapter electrical connector. The rotational electrical coupling comprises a first conductive component configured to be electrically connected to the lead electrical connector and rotatable with a proximal portion of the implantable medical lead, and a second conductive component electrically connected to the first conductive component and the adapter electrical connector. The second conductive component may be rotationally fixed. The first and second conductive components may comprise graphite or another soft metal.

    Abstract: An implantable medical device (IMD) including an elongated housing and a tine housing configured to attach to the elongated housing. The tine housing may support an extending plurality of tines and a distal-most electrode. An inner chamber is bounded at least in part by the elongated housing and the tine housing with an adhesive fill port in fluid communication with the inner chamber. A method of assembling the IMD includes forming the inner chamber and substantially filling the inner chamber with an adhesive through the adhesive fill port. The method may include curing the filling adhesive.

    Abstract: A leadless pacing system includes a leadless pacing device and a sensing extension extending from a housing of the leadless pacing device. The sensing extension includes one or more electrodes with which the leadless pacing device may sense electrical cardiac activity. The one or more electrodes of the sensing extension may be carried by a self-supporting body that is configured to passively position the one or more electrodes proximate or within a chamber of the heart other than the chamber in which the LPD is implanted.

    Abstract: Various fixation techniques for implantable medical device (IMDs) are described. In one example, an assembly comprises an IMD; and a set of active fixation tines attached to the IMD. The active fixation tines in the set are deployable from a spring-loaded position in which distal ends of the active fixation tines point away from the IMD to a hooked position in which the active fixation tines bend back towards the IMD. The active fixation tines are configured to secure the IMD to a patient tissue when deployed while the distal ends of the active fixation tines are positioned adjacent to the patient tissue.

    Abstract: An example device includes an elongated housing, a first and second electrode, and signal generation circuitry. The housing can be implanted within a single first chamber of the heart. The first electrode extends distally from the distal end of the elongated housing. A distal end of the first electrode can penetrate into wall tissue of a second chamber of the heart. The second electrode, extending from the distal end of the elongated housing, is configured to flexibly maintain contact with the wall tissue of the first chamber without penetration of the wall tissue of the first chamber by the second electrode. Signal generation circuitry can be within the elongated housing and coupled to the first and second electrode. The signal generation circuitry can deliver cardiac pacing to the second chamber via the first electrode and the first chamber via the second electrode.

    Abstract: A fixation mechanism of an implantable medical device is formed by a plurality of tines fixedly mounted around a perimeter of a distal end of the device. Each tine may be said to include a first segment fixedly attached to the device, a second segment extending from the first segment, and a third segment, to which the second segment extends. When the device is loaded in a lumen of a delivery tool and a rounded free distal end of each tine engages a sidewall that defines the lumen, to hold the tines in a spring-loaded condition, the first segment of each tine, which has a spring-biased pre-formed curvature, becomes relatively straightened, and the third segment of each tine, which is terminated by the free distal end, extends away from the axis of the device at an acute angle in a range from about 45 degrees to about 75 degrees.
