    Abstract: An implantable medical device includes a device housing, a fixation device, a first prong projecting from a proximal end of the device housing and a second prong projecting from the proximal end of the device housing. The second prong is spaced apart from the first prong. The first prong includes a first flange projecting away from a longitudinal axis of the device housing. The second prong includes a second flange projecting away from the longitudinal axis. The first prong and the second prong are configured to extend to a first flange diameter in a relaxed configuration and to extend to a second flange diameter in an expanded configuration.

    Abstract: A device for the active fixation of an implantable medical lead includes a housing, a tine assembly, and rotatable shaft. The housing includes a proximal end for connecting to the lead and a distal end opposite the proximal end. The housing defines a housing lumen having a longitudinal axis extending between the proximal end and the distal end. The tine assembly is disposed within the housing lumen. The tine assembly includes at least one tine configured to self-bias from a linear configuration within the housing to a curved configuration outside of the housing. The rotatable shaft extends through the housing lumen. The shaft is configured to engage the tine assembly such that rotation of the shaft transitions the at least one tine between the linear configuration and the curved configuration.

    Abstract: A leadless pacing device may include a power supply for providing a power supply voltage, a housing having a first end and a second end with a side extending between the first end and the second end, and a set of electrodes supported by the housing and in communication with the power supply. When leadless pacing device is disposed within a coronary sinus of a patient's heart, the housing may facilitate blood flow across the housing. The housing may include fixing members extending radially outward from the side of the housing to engage a wall of the coronary sinus and expand the coronary sinus to allow blood to flow past the housing. In some cases, the housing may have a recess along a length thereof that allows blood to flow past the housing. The recess may include a groove, a flat feature, or other feature.

    Abstract: A leadless pacing device may include a housing, a distal extension extending distally of a distal end of the housing, one or more electrodes supported by the housing, a distal electrode supported by the distal extension, and a processing module located within an interior space of the housing and electrically coupled to the one or more electrodes supported by the housing and the distal electrode supported by the distal extension. The housing may be positioned within a coronary sinus and the distal extension may be positioned within a vessel extending from the coronary sinus. The processing module may determine whether cardiac events occurred based on near-field signals and/or far-field signals sensed using the one or more electrodes supported by the housing and the distal electrode. The processing module may generate cardiac stimulation pulses based on the determination of whether a cardiac event occurred and where it occurred.
