Reduce Pain through Medical Device
Because of the opioid addiction epidemic in the US, there has been a push this year to encourage the development of non-addictive methods to Reduce chronic and Acute pain.
The SprintPNS (peripheral nerve stimulation) device consists of an electrical lead that is guided to its placement position via ultrasound imaging. The lead is positioned up to 2 centimeters from the target nerve, where its function is most efficient. It can be positioned in various ways to stimulate different nerve fibers. The other end of the lead is connected to a pulse generator, which is a patch-like device that receives its signal wirelessly from a small, hand-held controller. The device can be worn for up to 60 days. The lead is coiled, which allows ingrowth of fibrotic tissue at the lead exit site, anchoring the lead and also reduce pain and chance that infection could develop.
Quell by NeuroMetrix
Quell supports patients with chronic back, arthritic, nerve, leg, and foot pain by using neurostimulation technology to tap into the body’s normal pain response and block pain signals. For daytime and overnight use the wearable interface is FDA-cleared. It is inserted into a cuff that can be placed on the body and has an accompanying software that helps individuals control pain management and chronic pain-affected sleep habits.
A clinical study of 713 Quell users published in April 2018 by the Journal of Pain Research found that 80% reported changes in their chronic pain and about 66% reported reductions in their usage of pain medication due to the use of Quell. On average, for 35 hours per week, study participants used Quell.
Since pain is highly personal and all persons handle it differently, people with chronic pain frequently require a range of medications to find relief-what we call a “toolbox approach” to chronic pain.
StimRouter by Bioness Via peripheral nerve stimulation, this long-term pain solution treats chronic nerve pain. Since releasing in 2016, it has been used on 24 separate peripheral nerves. “Mark Geiger, global director of marketing implantables at Bioness, the company that produces StimRouter, says the device is 15 centimetres and “feels like a limp piece of spaghetti.
“The nerve does not transmit a pain signal by stimulating the target peripheral nerve with a tiny amount of energy that feels like a mild tingling sensation. This stimulus will cause the nerve to function more normally over time,” Geiger says. “So, compared to global pain reduction with oral or IV pain medication with all the typical, sometimes deleterious side effects, the difference is targeted pain management at the source of the pain.”
The StimRouter, when the patient is under local anaesthesia, is inserted through the skin. Patients will provide input to the doctor who is implanting the system right away.A permanent solution intended to last a lifetime is the StimRouter. In many cases patients use the StimRouter for shorter durations over time with increasing carry-over pain relief dependent on many hundreds of implants, ensuring pain relief lasts for hours/days after the patient shuts off the StimRouter,
