The present invention provides a fully intrathoracic artificial pacemaker. The pacemaker is of sufficiently compact size to allow for implantation of both the electrode and the power source within the chest cavity. In exemplary embodiments, a screw-type electrode is used for connection to heart tissue, and a relatively short lead is used to connect the electrode to a battery unit, which can comprise electronics for control of the pacemaker. An assembly for implanting the pacemaker, as well as methods of implanting the pacemaker, are disclosed. In embodiments, the device is designed as a fetal pacemaker.

Artificial cardiac pacemaker device assembly

A fully implantable cardiac pacemaker system is provided. The pacemaker system includes a pacemaker having an electrode sub-assembly containing an electrode and a base into which the electrode is embedded. It also includes an implantable package that has electronic components for providing electrical pulses to a patient's heart. The pacemaker also has a power supply and a flexible electrically conductive lead that connects the electronic components to the electrode. In addition to the pacemaker, the pacemaker system includes a removable insertion casing that is physically attached to the base portion of the electrode sub-assembly. Upon insertion of the pacemaker into a patient's heart, the pacemaker is detached from the removable insertion casing and deployed fully in the patient's chest. The pacemaker system has particular use in fetal applications.
