Overview

Increased clinical data with our micro-invasive pressure sensor
IntraSense comparison

The IntraSense series absolute pressure sensors are designed to fit into a 1-French hypo tube. The sensor comes pre-attached to cabling, simplifying the connection for the end user. The fully encapsulated electronics allow the device to be used without additional gel or encapsulant. This sensor compares pressure in vivo to an onboard vacuum cavity for reference to an absolute standard. It delivers accurate and stable pressure for acute procedures in the clinically useful range of -300mmHg to +500mmHg (460mmHg to 1260mmHg absolute) and from 10°C to 60°C. The output is stable in 37°C saline, with typical drifts of <2mmHg absolute maximum per 24 hours. The device is available either as a sensor plus cable, or with an optional 4- pin PCB board attached to the proximal end. 

Benefits

  • IntraSense sensor die measures 750μm × 220μm × 75μm
  • Accurate pressure sensing anywhere in the anatomy
  • Uses resistive MEMS technology and encapsulated wire/pad junctions for easy integration
  • Optional light shield to reduce light sensitivity
  • Designed to be used without additional gel
  • High part-to-part and IoT-to-IoT repeatability
  • TE provides the sensor with the cable pre-attached

Applications

Minimally Invasive Equipment
  • Diagnostic catheter
  • Therapeutic catheter
  • Disposable scopes
  • Biopsy needles
  • Ablation equipment

 

  1. IntraSense Invasive Pressure Sensor Overview (English)

TE Connectivity’s IntraSense is one of the most miniature pressure sensors in the market and simplifies pressure monitoring directly in the anatomy, enabling more controlled procedures and better clinical data.

FAQ

FREQUENTLY ASKED QUESTIONS

Q: How do we mount the sensor?

A: We have an Application Note with some helpful tips, or if you prefer, we can engage with TE Medical to potentially build a complete solution.

 

Q: What sterilization methods can be used with Intrasense?

A: Intrasense can be sterilized with ETO gas.  Other methods are being investigated.

 

Q: Can Intrasense be resterilized and reused?  

A: No, Intrasense is a single-use product.

 

Q: Can we just buy the sensor and not the cable assembly?  

A: No, because we cannot test parts until the cable has been attached.

 

Q: Can we buy this with a small connector on the proximal end?

A: We do not have a connector for Intrasense available at this time.
