Abstract:
1. An implantable medical device (IMD) comprising: a housing; a pressure sensor disposed within the housing and having a pressure sensing interface disposed along a first plane; a pressure sensor mount disposed within the housing and supporting the pressure sensor, wherein the mount permits the pressure sensor to move in a direction generally perpendicular to the first plane; an anchor prong tract disposed within the housing; an anchor prong disposed within the tract and moveable from a retracted position to an extended position; an anchor prong piercing head coupled to a distal end of the anchor prong and configured to pierce a substrate when moved in a first direction corresponding to moving the anchor prong from the retracted position to the extended position; and an anchor retention mechanism coupled to the anchor prong to preclude movement of the housing in a second direction that is opposite to the first direction after piercing the substrate, wherein the pressure sensor mount includes a threaded track and the pressure sensor includes a threaded portion that engages the threaded track such that rotation of the pressure sensor causes the pressure sensor to move in the direction generally perpendicular to the first plane.
