Implantable pressure sensor device

An implantable pressure sensor device (100) including a housing (10) having:

• a. opposing front faces (14/16) with non-circular perimeters,
• b. a tube (30) extending from and between the perimeters of the front faces (14/16),
• c. an interior volume (12) within the tube (30) and the front faces (14/16), the housing being at least partially formed of a pressure transmitting membrane (20) configured to:
• (1) reversibly deform, and
• (2) maintain its surface area,
• when the interior volume (12) of the housing (10) changes.
