Abstract
A pressure sensitive device including a body having a proximal portion and a distal portion opposite the proximal portion, the distal portion being made of a shape memory alloy, a flexible diaphragm at least partially surrounding the body and defining a fluid chamber between the flexible diaphragm and the distal portion of the body, and a non-compressible fluid disposed within the flexible diaphragm and exhibiting a hydraulic pressure in communication with the flexible diaphragm.
Claims18
A pressure sensitive device comprising:
- a body including a proximal portion and a distal portion opposite the proximal portion, the distal portion being made of a shape memory alloy;
- a flexible diaphragm surrounding the distal portion of the body and defining a fluid chamber between the flexible diaphragm and the distal portion of the body;
- and
- a non-compressible fluid disposed within the flexible diaphragm and exhibiting a hydraulic pressure in communication with the flexible diaphragm.
1 more element
A pressure sensing system comprising:
- a pressure sensitive device including:
- a tubular body having a transition region including a plurality of expandable arms extending therefrom, each arm from the plurality of expandable arms defining a length and each arm from the plurality of expandable arms defining a planar region extending at least partially along the length;
- a diaphragm surrounding the plurality of expandable arms, the diaphragm defining a fluid chamber between the diaphragm and the tubular body;
- a non-compressible fluid disposed within the fluid chamber and configured to exhibit a hydraulic pressure on the diaphragm;
- and
- a housing remote from and in communication with the pressure sensitive device, the housing including a pressure measuring system disposed therein, and the pressure measuring system including a Micro-Electro-Mechanic Systems (“MEMS”) device configured to be in communication with the hydraulic pressure exhibited by the non-compressible fluid.
