Methods, systems and devices for providing cardiac resynchronization therapy (CRT) to a patient using a leadless cardiac pacemaker and an extracardiac device. The extracardiac device is configured to analyze one or more QRS complexes of the patient's heart, determine whether fusion pacing is taking place, and, if not, to communicate with the leadless cardiac pacemaker to adjust intervals used in the CRT in order to generate desirable fusion of the pace and intrinsic signals. The extracardiac device may take the form of a subcutaneous implantable monitor, a subcutaneous implantable defibrillator, or other devices including wearable devices.

Cardiac resynchronization using fusion promotion for timing management

Implantable medical device systems and methods of use including an implantable first medical device having a lead with a transducer thereon and an implantable second medical device having a receiver for receiving energy emitted by the transducer. The lead may be placed in an internal thoracic vein, and other locations may be used as well. The implantable second medical device may be placed in or on the heart or an associated blood vessel.

Internal thoracic vein placement of a transmitter electrode for leadless stimulation of the heart

This invention relates to the use of an electromagnetic generator and a pressure bladder located within a biological body in such a position to take advantage of the pressure fluctuations found within that body to produce electrical power. The invention uses these pressure fluctuations to displace the moving parts of a generator, to produce electricity in accordance with the Faraday principal, to power implanted devices.

Energy harvester for an implant device

An ablation catheter including a probe, an electrode mounted on the probe so as to be movable relative thereto, a remote-operated actuator means for moving the electrode, an elongate conductor connected to the electrode and insulation provided around the conductor. The insulation can include a sleeve axially slidable on the probe, the elongate conductor extending longitudinally between the probe and the insulation sleeve and the insulation sleeve being retractable at least in part into a recess formed in a rearward portion of the probe.

Ablation catheter

With reference to the figure, an ablation catheter (,) for use in heart surgery comprises a probe (,), a tubular electrode (,) mounted on the probe, so as to axially be slidable relative thereto, and remote-operated actuator means (,) for so sliding the electrode (,). The probe (,) is of electrically-insulating material, and comprises a tip (,), an axially-extending shaft (,), and a rear end portion (,). A surface groove (,) is formed in the probe which extends longitudinally up to the tip (,). The groove (,) locates a conductor (,) which interconnects the electrode (,) with a controllable source (,) of electrical energy and is enclosed in an insulating sheath (,) of flexible construction. The flexible sheath (,), and conductor (,) therein are axially slidable within the groove (,) of the catheter (,). The sheath (,) provides for electrical insulation of the conductor (,) as the electrode (,) is moved along the probe shaft (,). In use, the catheter (,) is employed to create long endocardial lesions in cardiac chambers by application of radio frequency current provided by the source (,). Contiguous lesions are created, in a series of steps, by careful, remote-operated movement of the electrode (,), and energization of the same.
