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.

Systems and methods for treating cardiac arrhythmias

Implantable leadless pacing devices and medical device systems including an implantable leadless pacing device are disclosed. An example implantable leadless pacing device may include a pacing capsule. The pacing capsule may include a housing. The housing may have a proximal region and a distal region. A first electrode may be disposed along the distal region. One or more anchoring members may be coupled to the distal region. The anchoring members may each include a region with a compound curve.

Leadless cardiac pacing devices

A leadless pacing device may include a housing having a proximal end and a distal end, and a set of one or more electrodes supported by the housing. The housing may include a first portion and a second portion, with a guide wire port extending through the second portion. A guide wire lumen may extend through the second portion of the housing and the guide wire port may be located at a proximal end of the guide wire lumen. An exposed electrode may be located on a side of the housing that is opposite a side on which the guide wire port is located. The leadless pacing device may include a fixing member on the housing and extending radially from the housing. The leadless pacing device may further include a proximal member extending proximally from a proximal end of the housing. The proximal member may be elongated.

An implantable leadless cardiac pacing device and associated retrieval features. The implantable device includes a docking member extending from the proximal end of the housing of the implantable device including a covering surrounding at least a portion of the docking member configured to facilitate retrieval of the implantable leadless cardiac pacing device.

Leadless cardiac pacemaker with retrieval features

A system may include a leadless cardiac pacing device including a body, a proximal hub, and a helical fixation member opposite the proximal hub; and a first elongate shaft having a lumen extending from a distal end of the elongate shaft proximally into the elongate shaft and a transverse member extending transversely across the lumen. The proximal hub may include a transverse channel extending into the proximal hub, the transverse channel being configured to engage the transverse member.

Tools and systems for implanting and/or retrieving a leadless cardiac pacing device with helix fixation

An implantation and/or retrieval device for a leadless cardiac pacing device may include a first elongate shaft including a lumen; a second elongate shaft slidably disposed within the lumen of the first elongate shaft; an end cap assembly fixedly attached to a distal end of the first elongate shaft; and a plurality of wires attached to the second elongate shaft and extending distally from the end cap assembly, the plurality of wires being movable relative to the end cap assembly. The plurality of wires is configured to engage a proximal hub of the leadless cardiac pacing device. The plurality of wires forms a plurality of wire loops extending distally from the end cap assembly.

An implantable leadless cardiac pacing device and associated delivery and retrieval devices. The implantable device includes a docking member extending from the proximal end of the housing of the implantable device configured to engage with the delivery and/or retrieval device to facilitate delivery and/or retrieval of the implantable leadless cardiac pacing device.

Leadless cardiac pacemaker with delivery and/or retrieval features

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 delivery device may include more than one deflection mechanism for deflecting the proximal section at multiple deflection regions. The delivery device may include more than one tubular member that are translatable relative to one another, and the one or more tubular members may include fixed curve portions. The delivery device may include an atraumatic or bumper tip at the distal end of the holding section.

Delivery devices and methods for leadless cardiac devices

Implantable leadless pacing devices and medical device systems including an implantable leadless pacing device are disclosed. An example implantable leadless pacing device may include a pacing capsule. The pacing capsule may include a housing. The housing may have a proximal region and a distal region. A first electrode may be disposed along the distal region. An anchoring member may be coupled to the distal region. One or more anti-rotation members may be fixedly attached to the distal region.

An implantable medical device (IMD) may include a fixation module, and a device module that is configured to be releasably connected to the fixation module. The device module may have a proximal end and a distal end, and may include a power source and a controller that is operably coupled to the power source. The controller may be configured to sense cardiac electrical activity via two or more electrodes and/or deliver pacing pulses via two or more electrodes. The device module may include a first part of a releasable connector while the fixation module may include a second part of the releasable connector, wherein the first part of the releasable connector and the second part of the releasable connector cooperate to releasably connect the device module with the fixation module.
