Millar - Model TiSense -Long-Term Implantable Pressure Sensor Module
TiSense by Millar is an advanced medical device technology designed for chronic pressure measurement over prolonged periods, exceeding five years. This MEMS piezo-resistive sensor module is made from robust materials such as titanium and platinum-iridium, ensuring reliability and safety for long-term medical use. TiSense effectively measures pressure using a silicone oil-filled membrane system with remarkable accuracy and stability, even after millions of pressure cycles. It is particularly significant in managing conditions like chronic heart failure, hydrocephalus, and intraocular pressure by providing precise and continuous pressure data. The module is ISO 10993 compliant, highlighting its biocompatibility for medical applications. TiSense undergoes rigorous drift testing, simulating human body conditions through pressure cycles at 37°C, to ensure performance over its lifespan. This technology stands out due to its innovative approach, adaptability to various medical applications, and its adaptability to different clinical scenarios.
As market leaders in the acute pressure measurement space, Millar is Making Medical Devices Smarter Long-Term by offering the newest technology on the market for chronic pressure readings: TiSense.
This novel technology platform is designed for implantation periods of greater than 5 years. Made of titanium, encapsulated, and hermetically sealed, TiSense is revolutionizing the industry.
From an innovation perspective, we offer something greater than our standard catheter-based offerings, which currently range from 7-29 days of use. This module is ISO 10993 compliant and is extremely versatile - tailored to each customer’s unique use case or application.
Module Configuration and Technical Information
TiSense is a MEMS piezo-resistive sensor module filled with silicone oil, communicating pressure from a thin membrane in front. All body contacting portions are constructed from titanium, the pins from the feedthrough are platinum-iridium. TiSense measuring system respects internal vacuum pressures.
Note: Care should be taken when soldering wires on pins to prevent heat damage. It is recommended to use a flex PCB to terminate the pins.
TiSense can be used in various medical contexts like chronic heart failure and hydrocephalus, allowing for accurate, dynamic pressure measurements.
Example Clinical Applications
Chronic Heart Failure
Suited for exposure to millions of pressure cycles, TiSense enables devices that can be placed at various points in the heart, offering readily available pressure data.
Hydrocephalus
Paired with a shunt system, TiSense aids in managing CSF pressure to a desired value, enabling continuous measurement of intracranial pressure.
Intra Ocular Pressure
With a minimal height profile, TiSense is suited for long-term implantation in the inner eye, interfacing with a hermetic implant that houses signal conditioning electronics.
