the transceiver 145 to better perform like a torque device in another embodiment transceiver 145 only sends out the processed results for display without the pressure signals derived from the sensor chip 116 the proximal portion of the pressure wire 110 is more tolerant of having any stiff sections that are required to implement signal conditioning and processing components these components are being off loaded from the torque device to enable a smaller form factor for the torque device that also doubles as a transceiver note that this proximal portion of the pressure wire does not enter the human body in a modern catheterization laboratory many pieces of equipment vie for the limited space available around the sterile patient table able to provide a minimally invasive pressure measurement device that conforms as much as possible to other interventional device like a balloon improves the work flow immensely as all the communication between the sensor chip and the torque device takes place in between the insulating layers and the conductive traces the pressure sensing can also be implemented in the form of a stand alone sleeve that is delivered over the preferred guide wire that the user has chosen this approach of performing the pressure measurement differs from the approach of implementing a pressure wire the advantage of this approach is that the operator can use his preferred guide wire without any possible compromise on the wire performance but with the possible disadvantage that an additional catheter however small needs to.
