Abstract: Implantable medical devices are constructed with a dampening layer to limit motion of components inside a housing of the implantable medical devices. The dampening layer may have features to provide thermal isolation for certain components. The dampening layer may have features to allow mechanical vibration of selected components. The dampening layer may have features to ensure an air space exists to enable a residual gas analysis test.

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: Delivery devices, systems, and methods for delivering implantable leadless pacing devices are disclosed. An example delivery device may include an outer tubular member including a lumen extending from a proximal end to a distal end thereof and an intermediate tubular member including a lumen extending from a proximal end to a distal end thereof. A distal holding section may be coupled to the intermediate tubular member and define a cavity therein for receiving a proximal implantable leadless pacing device and a distal implantable leadless pacing device in a linear arrangement. The distal holding section may have a proximal body portion and a distal body portion. The proximal body portion may be more flexible than the distal body portion. An inner tubular member including a lumen extending from a proximal end to a distal end thereof may be slidably disposed within the lumen of the intermediate tubular member.

Abstract: A leadless pacing device may include a housing having a proximal end and a distal end, and one or more electrodes supported by the housing. The housing may include a body portion and a header. A distal extension may extend distally from the header of the housing, the distal extension including one or more electrodes. The header may include a guide wire port and a guide wire lumen may extend from the guide wire port through the header of the housing and through the distal extension. A fixation member may extend from the header of the housing. The header may be formed from an over mold process.

Abstract: Delivery devices, systems, and methods for delivering implantable leadless pacing devices are disclosed. An example delivery device may include a proximal section including a deflection mechanism for deflecting the proximal section, and a distal holding section extending distally of a distal end of the proximal section and defining a cavity therein for receiving an implantable leadless pacing device. The distal holding section may be structured to have portions that flex and bend while allowing the implantable device to be recaptured within the distal holding section.

Abstract: Disclosed herein is an implantable medical device including a housing, a header, a connector port, and a collet assembly. The header can be arranged with the housing. The connector port can be arranged within the header and configured to couple an implantable lead to the header. The collet assembly can be arranged within the connector port and configured to frictionally engage a portion of the implantable lead and to secure the implantable lead with the header in response to insertion of the portion of the implantable lead into the connector port.

Abstract: Catheter and implantable leadless pacing devices, systems, and methods utilizing catheters and implantable leadless pacing devices are disclosed. An example catheter system may include a holding structure extending distally from a tubular member. An implantable device, such as a leadless pacing device, may be located within a cavity of the holding structure. The holding structure may include one or more electrical ports adjacent the proximal end of the holding structure and adjacent or proximal of the proximal end of the implantable device. The electrical ports may provide a conductive pathway extending through the distal structure to allow electrical signals to pass through the distal structure to and/or from the implantable device.
