Smart Catheter and Flexible Electronics Packaging Platforms

IME has developed various types of minimally invasive medical devices packaged via flexible electronics for cardiology and neurology applications. Cardiology applications include vascular graft sensor for early prosthetic graft failure detection, sensor-enhanced guidewire for endovascular procedures, and renal denervation guidewire to address resistant hypertension and other abnormally highly activated sympathetic diseases. Neurology applications include high density 3D neural probe array microsystem for deep brain neural recording/ stimulation application, wireless intracranial pressure (ICP) microsystem for multimodality (temperature, oxygen and pressure) neuromonitoring of severe head injury patients, and neuro-stimulation devices for peripheral nerve disease. Other applications include ultrasound for imaging and therapy.  These medical devices are realized using Micro-Electro-Mechanical System (MEMS)-based sensors and Application-Specific Integrated Circuit (ASIC) integration via Chip-on-Flex (CoF) packaging techniques.
Wearable Electronics Device Platform   
 

IME has developed various types of wearable devices for healthcare monitoring purposes, such as smart sensor patch for early detection of extravasation injury during intravenous (IV) infusion, dry electroencephalogram (EEG) electrode cap for long-term epilepsy monitoring, and a cricoid pressure sensing patch for gastric aspiration procedure. These technologies can monitor a patient’s vital signs or symptoms and provide quantitative feedback, transmit data wirelessly to health providers on abnormal patterns in patient’s condition, allowing for early medical intervention and better patient care.
