SHORT DESCRIPTION
This technology introduces a wireless, miniaturized, implantable catheter-type oximeter designed to offer real-time monitoring of intravascular oxygen levels for post-cardiothoracic surgery care.

BACKGROUND
Accurate, real-time monitoring of intravascular oxygen levels is crucial for patients recovering from cardiothoracic surgery. Existing methods, which often involve the use of glass fiber-optic catheters, come with significant risks, including blood vessel damage, thrombosis, and infection. Moreover, these methods' reliance on physical tethers to power supplies and data acquisition systems restricts patient mobility and contributes to the clutter within intensive care units.

ABSTRACT
This invention presents a novel wireless, miniaturized, implantable optoelectronic catheter system for monitoring localized tissue oxygenation, heart rate, and respiratory activity. By incorporating optical components directly onto the probe and encapsulating them in soft, biocompatible materials, this technology offers a safer, more patient-friendly alternative to traditional methods. Its wireless functionality and flexible construction eliminate the need for physical tethers, improving patient mobility and reducing ICU clutter.

APPLICATIONS

  • Real-time monitoring of intravascular oxygen levels in post-cardiothoracic surgery patients.

  • Continuous tracking of heart rate and respiratory activity without the need for physical tethers.

ADVANTAGES

  • Minimizes risks of blood vessel damage, thrombosis, and infection associated with traditional catheters.

  • Enhances patient mobility and comfort by eliminating physical tethers to monitoring equipment.
