Health Care Issue

There are over 200,000 cases of ischemic strokes every year, 87% of all cases of strokes. There are two types of ischemic strokes, thrombotic and embolic. Thrombotic strokes, which are caused by blood clots within an artery that goes to the brain, are the most common [1]. If the patient does not receive proper treatment within three hours after a stroke occurs, risk factors are much higher. The designed device will be a non invasive Doppler ultrasound patch to read issues pertaining to the carotid. The device will also track several other biomarkers in order to accomplish the goal to quickly detect the presence of a stroke as well as allow speedy treatment to decrease the number of deaths or permanent damage caused by a thrombotic stroke every year.

The main patent relating to our device is the ultrasound patch while all the other patents may be useful in developing our device. The ultrasound patch has the ability to connect wirelessly to an external device. Our goal is to add other technology to the existing patch and that is why their are other patents such as the electronic skin and battery free skin.
Ultrasound patch [2]
Microphone Arrays for Listening to Internal Organs of the Human Body [3]
Semi-disposable wearable medical electronic patches [4]
Wireless fetal monitor (Heartbeat and doppler ultrasound)[5]
Electronic skin patch for real time monitoring of cardiac activity and personal health management [6]
Battery-free, stretchable optoelectronic systems for wireless optical characterization of the skin [7]

We research the people and places that we thought would respond well to our device. The score of one represents that fact that we didn't actually contact the customers.
The competitors we researched are either for in hospital use or are simply just a monitoring device with no other added features. The Life Watch seemed to be our biggest competitor but they charge a monthly subscription and do not notify the patient if anything is seriously wrong at that moment.
IP Position
There were many other patents that we can adapt to our product mainly using the ultrasound patch.
