Abstract
A catheter die is provided and includes an elongate body having first and second opposing end portions and an end face at the first one of the first and second opposing end portions. The elongate body defines a cavity within the first end portion with an interior facing surface of the cavity disposed to extend alongside at least a portion of the first end face. At least one or more piezoresistive pressure sensors are operably disposed proximate to the cavity.

A catheter die, comprising:
- an elongate body having sidewalls, longitudinal first and second opposing end portions of the sidewalls and an end face at the first one of the longitudinal first and second end portions,
- the sidewalls having a longitudinal length that is substantially larger than any planar dimension of the end face,
- the elongate body defining a cavity having an interior facing surface proximate to the end face such that a portion of the end face is defined as a diaphragm,
- the interior facing surface being disposed alongside at least a portion of the end face;
- and
- at least one or more piezoresistive pressure sensors operably disposed proximate to the diaphragm and the cavity.

A method of assembling a catheter die, comprising:
- forming an elongate body having first and second opposing end portions and an end face at the first one of the first and second opposing end portions, the elongate body having a longitudinal length that is substantially larger than any planar dimension of the end face;
- defining a cavity within the first end portion such that an interior facing surface of the cavity is disposed alongside at least a portion of the end face;
- and
- operably disposing a piezoresistive pressure sensor proximate to the cavity.
