1. A wireless and leadless left atrial pressure measurement device configured for delivery through a thickness of an atrial septum via a minimally invasive delivery tool, the device comprising:
a wireless pressure sensor comprising a proximal portion, a distal portion opposite the proximal portion, and a housing containing a hermetically sealed cavity containing a sensor circuit; a first anchoring element comprising a first distal end and a first free proximal end generally opposite the first distal end, the first distal end operably coupled to the wireless pressure sensor, the first anchoring element extending proximally away from the proximal portion; and a second anchoring element comprising a second distal end and a second free proximal end generally opposite the second distal end, the second distal end operably coupled to the wireless pressure sensor, the second anchoring element extending proximally away from the proximal portion; wherein, when the first and second anchoring elements are free to assume a biased state, the first free proximal end and second free proximal end extend in generally opposite directions and the first anchoring element projects generally distally. |
