Neuspera Medical is a startup company located in San Jose, CA.  They are developing miniaturized neuromodulation implants that are externally powered from a wearable device.

In December 2019, Neuspera announced that it had received FDA’s approval to implant their systems under IDE.  Neuspera now announced that they closed a $65M series C equity financing round to fund their trial on the use of their device in patients with Urinary Urgency Incontinence (UUI), a symptom of overactive bladder.  The Series C round was co-led by Vertex Ventures HC and Treo Ventures.

Neuspera is a startup company located in San Jose, CA.  They are developing miniaturized neuromodulation implants that are externally powered from a wearable device.

According to Neuspera, their “Mid-Field Powering” technology uses evanescent and propagating electromagnetic waves to power implanted medical devices to beyond 10cm of depth. Their technology is claimed to use the body as a natural waveguide to focus power ensuring energy is delivered to where it is needed.

In December 2019, Neuspera announced that it had received FDA’s approval to implant their systems under IDE.  Neuspera now announced that it had performed the first human implants as part of their SANS-UUI two-stage seamless pivotal clinical trial to support FDA approval for patients with Urinary Urgency Incontinence (UUI), a symptom of overactive bladder.

Neuspera is a startup company located in San Jose, CA.  They are developing miniaturized neuromodulation implants that are externally powered from a wearable device.

According to Neuspera, their “Mid-Field Powering” technology uses evanescent and propagating electromagnetic waves to power implanted medical devices to beyond 10cm of depth. Their technology is claimed to use the body as a natural waveguide to focus power ensuring energy is delivered to where it is needed.

In addition to coming up with their own neuromodulation system, Neuspera hopes to license its Mid-Field Powering technology to recharge or power other types of implantable devices.  According to their technical publications and patent, they use a phased array microwave transmitter operating at a 1.6GHz local minimum in tissue absorption to maximize power transfer.  Per the patent, if the power coupled into tissue is allowed to meet the maximum permitted level of exposure, up to 2.2 mW can be transferred by their system.

Neuspera Medical announced that it has raised a new total of $26 million in equity financing, following the closing of the second tranche of its series B round, to help fund clinical testing programs for its neuromodulation implants.
