Abstract
Apparatus, systems, and methods are provided for monitoring AF episodes, delivering ATP pulses, and/or achieving electrical isolation of the left atrial appendage (LAA) of a patient's heart and/or preventing thrombus formation after electrical isolation. For example, devices are provided that may implanted from within the left atrium, e.g., to isolate the LAA, prevent thrombus formation within the LAA, facilitate endothelialization, and/or deliver pacing.
Claims23
A leadless pacemaker device for implantation within or near a left atrial appendage extending from a left atrium of a heart to monitor and/or treat a patient with conduction abnormalities and/or cardiac dysrhythmias, the device comprising:
- a battery capable of storing electrical energy;
- at least one electrode capable of sensing and pacing the left atrium;
- a control processor capable of processing data;
- a communication module to communicate outside of the patient;
- and
- a cover portion designed to prevent thrombus from within the left atrial appendage of the left atrium to embolize out of the left atrial appendage of the left atrium;
- wherein at least a portion of the device comprises a linear chain of subunits coupled together by connectors, wherein the connectors configured to allow each subunit to change orientation relative to any adjacent subunits.
An elongate implantable pacemaker system, comprising;
- a housing having a proximal end and a distal end, the housing sized for implantation within a left atrial appendage of a heart;
- a battery and a processor carried by the housing;
- an expandable cover operatively coupled with the housing;
- and
- at least one pacing electrode,
- wherein the housing is configured to undergo configuration change within a left atrium of the heart before being advanced into the left atrial appendage, and
- wherein the cover is adapted to prevent blood clots from leaving the left atrial appendage.
A leadless pacemaker system, comprising:
- a delivery sheath comprising a proximal end, a distal end sized for introduction into a left atrium of a heart, and a lumen extending between the proximal and distal ends;
- a pacemaker device comprising a plurality of elements deployable sequentially through the lumen from the distal end into the left atrium, the elements configured to adopt an expanded configuration within the left atrium;
- an actuator for advancing the elements from the left atrium into the left atrial appendage, and releasing the elements to implant the device within the left atrial appendage.
