When somebody overdoses on opioids, it is critically essential that they obtain a dose of the opioid-reversing drug naloxone as quickly as doable – in any other case, dying is a definite chance. That is the place a brand new implant is available in, because it mechanically dispenses naloxone from throughout the physique.
Its identify an acronym for “Implantable System for Opioid Security,” the iSOS implant is being developed by a workforce of scientists from MIT and the Harvard-affiliated Brigham and Girls’s Hospital.
The machine measures 78 mm lengthy by 12 mm vast by 8 mm thick. It accommodates 10 milligrams of naloxone in an built-in reservoir, plus it incorporates electronics reminiscent of a battery, vibrator and Bluetooth module, plus a number of ECG electrodes and a set of different sensors.
Ideally, it could be implanted proper under the pores and skin close to the photo voltaic plexus. This process might be rapidly carried out in a clinic utilizing a neighborhood anesthetic.
As soon as in place, the iSOS displays the affected person’s physique temperature, coronary heart fee, respiratory fee and blood oxygen saturation. If these parameters change in a fashion that signifies an opioid overdose has taken place, the machine prompts its vibrator to provide each a tactile and audible alert.
It additionally sends a warning to an app on the affected person’s smartphone. Within the occasion of a false-positive, the affected person can get the implant to “stand down” through that app. If they do not accomplish that instantly, although, the iSOS proceeds to quickly pump a dose of naloxone into their bloodstream. The app will even ship an alert to a predetermined emergency contact.

In lab assessments, the machine efficiently revived 96% of fentanyl-overdosed pigs inside a median of three.2 minutes. Its battery is at the moment good for 16 days of vital-signs monitoring, and may be wirelessly recharged as wanted.
The naloxone reservoir may be refilled through a hypodermic needle inserted by way of the pores and skin right into a port on prime of the implant. Given the truth that the drug lasts for at the very least 14 days at physique temperature, it’s envisioned that sufferers would merely go to a clinic as soon as each two weeks for a battery cost and a refill.
Whereas we’ve seen non-implant wearables designed to be used by opioid addicts who wish to survive unintended overdoses, the workforce behind the iSOS state that these methods sometimes do not ship a ample naloxone dosage quick sufficient. Moreover, as a result of these units have to be manually positioned on the physique every day, it is doable that many people would merely cease bothering to make use of them over time.
“This might actually tackle a big unmet want within the inhabitants that suffers from substance abuse and opiate dependency to assist mitigate overdoses, with the preliminary give attention to the high-risk inhabitants,” says MIT’s Assoc. Prof. Giovanni Traverso, senior writer of the research.
It’s hoped that human trials will begin inside three to 5 years, throughout which period a naloxone-dispensing implant being developed at Northwestern University may progress additional.
A paper on the MIT analysis was lately printed within the journal Device.
