Systems for monitoring left atrial pressure using implantable cardiac monitoring devices and, more specifically, to a left atrial pressure sensor implanted through a septal wall are presented herein.

Wireless MEMS left atrial pressure sensor

The disclosure relates in some aspects to an implantable pressure sensor and a method of measuring pressure. In some embodiments pressure may be measured through the use of an implantable lead incorporating one or more pressure sensors. In some aspects a pressure sensor is implemented in a micro-electromechanical system ('MEMS') that employs direct mechanical sensing. A biocompatible material is attached to one or more portions of the MEMS sensor to facilitate implant in a body of a patient. The MEMS sensor may thus be incorporated into an implantable lead for measuring blood pressure in, for example, one or more chambers of the patient's heart.

Implantable micro-electromechanical system sensor

A lead implanted across a heart wall such as an atrial septum includes structure for fixation to the wall. In some embodiments the distal end of the lead includes a sensor for measuring quantities such as pressure at a distal side of the wall. The fixation structures may be positioned on opposite sides of the wall after implant. The fixation structures may be aligned with the lead during delivery of the lead to the implant site and expanded from the lead at the implant site.
