Abstract

The present invention provides a pacing device and method that allows for preferential right atrial, at or near the His bundle, and ventricular pacing, either individually or in combination, including tri-ventricular pacing. The pacing device includes a power source and one or more logic circuits allowing for programmable delivery of pacing to any combination of the right atria, the para-Hisian region, and the right and/or the left ventricles. The pacing device allows the user to select which site(s) to pace as well at the appropriate relative timing of pacing impulse delivery to any of these three previously mentioned sites. The device is constructed and arranged to be combined with an atrial sensing/pacing electrode to allow for atrio-ventricular sequential tri-ventricular pacing or variants of such. Also, a defibrillator lead can be incorporated into the device to allow for protection from ventricular arrhythmias and sudden death.

Claims

1. A pacing device for pacing a plurality of regions of the heart comprising:

a main pacing device body, said main body housing a power source, a control unit, a plurality of logic circuitry coupled to said control unit, a plurality of ports, said plurality of ports constructed and arranged to receive at least one pacing lead constructed and arranged to pace the right atrium of the heart and at least one pacing lead constructed and arranged to pace at, or near the His bundle region of the heart, wherein pacing of said right atrium and said His bundle region results in synchronization of the heart chambers.

5. The pacing device according to claim 1 further including an additional pacing lead to pace the left ventricle, said left ventricle pacing lead coupled to said main control unit.

6. The pacing device according to claim 1 further including a defibrillator lead.

7. The pacing device according to claim 1 further including a monitor coupled to said control unit.

8. The pacing device according to claim 7 wherein said monitor allows a user to select which site, or combinations of sites, to pace.

9. The pacing device according to claim 7 wherein said monitor allows a user to select the appropriate relative timing of pacing impulse delivery to any of said sites containing said leads.

10. The pacing device according to claim 7 wherein said monitor is wirelessly coupled to said monitor device.

11. The pacing device according to claim 1 wherein said main control unit is programmed to select the sites of pacing.

12. The pacing device according to claim 1 wherein said main control unit is programmed to select the appropriate relative timing of pacing impulse delivery to each of said leads.

2. The pacing device according to claim 2 further including an additional pacing lead for pacing the right ventricle, said right ventricle pacing lead coupled to said control unit.

3. The pacing device according to claim 2 wherein said atrial pacing lead contains sensing logic for obtaining electrocardial information, said information being used to pace said device.

4. The pacing device according to claim 2 further including a sensing lead, said sensing lead constructed and arranged for obtaining electrocardial information and relaying said information to said sensing circuitry, said information being used to pace said device.

13. A method of pacing a plurality of regions of the heart comprising the steps of:

providing to a user a pacing device for pacing a plurality of regions of the heart, said pacing device comprising;

a main pacing device body, said main body housing a power source, a control unit, a plurality of logic circuitry coupled to said control unit, a plurality of ports, said plurality of ports constructed and arranged to receive at least one pacing lead constructed and arranged to pace the right atrium of the heart and at least one pacing lead pacing constructed and arranged to pace at, or near the His bundle region of the heart, wherein pacing of said right atrium and said His bundle region results in synchronization of the heart chambers;

coupling said right atrium lead to said control unit of said pacing device and placing said right atrium lead into a region of the right atrium of the heart;

coupling said His bundle lead to said control unit of said pacing device and placing said His bundle lead at or near the vicinity of the bundle of His;

coupling said ventricle lead to said control unit of said pacing device and placing said ventricle lead into the right ventricle;

programming said control unit to pace the right atrium, at or near the His bundle, and the right ventricle at the appropriate relative time; and

providing a pacing event to one or more areas of the heart.

14. The method of pacing a plurality of regions of the heart according to claim 13 wherein said ventricle lead is inserted into a vein of the coronary sinus for pacing the left ventricle.

15. The method of pacing a plurality of regions of the heart according to claim 13 further including a left ventricle lead coupled to said main control unit, said left ventricle lead placed within a vein of the coronary sinus to provide left ventricle pacing.

16. The method of pacing a plurality of regions of the heart according to claim 15 wherein said control unit is programmed to pace the left ventricle at the appropriate relative time.

17. The method of pacing a plurality of regions of the heart according to claim 14 wherein said ventricle lead includes at least two leads inserted into the veins of the coronary sinus for pacing the left ventricle.

18. The method of pacing a plurality of regions of the heart according to claim 17 wherein said control unit is programmed to pace each of the leads to the left ventricle at the appropriate relative time.
