Claims
- 1) An intracardiac pacer comprising:
a hermetic housing containing, a power source, a pacing circuit module; a resilient deployable shield adapted to conform to said housing during insertion and deployable to an expanded shape that engages and anchors said housing in an anatomic location inside the heart.
- 2) The device of claim 1 wherein said shield is made from a Nitinol mesh.
- 3) The device of claim 1 wherein said shield is made from a Dacron mesh.
- 4) The device of claim 1 wherein said power source is a lithium solid state cell.
- 5) The device of claim 1 wherein said power source is a rechargeable battery.
- 6) The device of claim 1 further comprising;
an electrode site located at the distal tip of said housing for sensing and pacing heart tissue.
- 7) The device of claim 1 further comprising a lead system extending from said distal end of said housing adapted for placement in the heart.
- 8) A method of treating the heart comprising:
inserting an ICP into the LAA; monitoring the atrial beat in the LAA; setting a timing interval based on the sensed depolarization of the atrium based on the signal in the LAA; programming the ICP to a pacing modality that supplies electrical energy to the LAA in response to a detected atrial beat measured in the LAA.
- 9) The method of claim 8 further comprising:
placing at least one electrode in a chamber selected from the group; LA, RA, LV, RV, and CS; coupling said electrode to said ICP; providing a pacing therapy from said ICP and said electrode.
- 10) The method of claim 8 further comprising:
a conventionally placed IPG coordinating its action with said ICP to provide dual chamber pacing therapy.
- 11) A method of treating a cardiac arrhythmia comprising the steps:
sensing an atrial depolarization from an electrode in the RA; sensing the same depolarization from an electrode in LAA or RAA; determine the conduction sequence and time interval between said measurements; pacing a ventricle chamber if said measurement indicates a “wide” QRS.
- 12) A method of treating a cardiac arrhythmia comprising the steps:
sensing an atrial depolarization from an electrode in the RAA; sensing the same depolarization from an electrode in LAA; determine the conduction sequence and time interval between said measurements; pacing the LA or LAA if said measurement indicates a “wide” atrial beat.
- 13) A method of treating a “wide QRS” cardiac arrhythmia comprising the steps:
sensing an atrial depolarization from an electrode in the RA; sensing the same depolarization from an electrode in LAA; determine the conduction sequence and time interval between said measurements; pacing the LA or LAA if said measurement indicates a “wide” atrial beat and committed pacing of both LV and RV.
