Abstract: Devices and methods for occluding the left atrial appendage (LAA) with a device having multifunctional capability. The device is delivered via transcatheter delivery into the LAA and anchored using a compliant frame and scaffold, which may be foam. The device further includes one or more electronic systems to provide a multitude of features related to sensing, electrical stimulation, pacing, communication, etc. The device may have an open configuration where an opening in the proximal end of the device allows for delivery of one or more sensors into and/or through the device. The device may be manipulated into a closed configuration to secure the electronic systems therein and close off the proximal end to provide the occlusive effects. The electronic systems therein may then be used for the various electronic and other functions.
