Key result
An intravascular wireless and batteryless microscale stimulator achieved a >5 V stimulation threshold with up to 20 mm displacement and 20° misalignment in bovine tissue and FEM simulations.
Why the study?
Achieving efficient wireless power transfer and effective operational range within anatomical constraints has remained a challenge for batteryless implantable biomedical devices.

Early human data support feasibility of batteryless intravascular stimulation; leaves open clinical translation pending larger safety and efficacy trials.
A novel intravascular wireless and batteryless microscale stimulator demonstrated technical feasibility and sufficient power transfer in preclinical models, suggesting potential for minimally invasive pacing.
Abiri et al. (2020) studied Implantable device candidates. Intravascular wireless and batteryless microscale stimulator was evaluated on Wireless capacity (stimulation threshold, displacement, and misalignment). An intravascular wireless and batteryless microscale stimulator achieved a >5 V stimulation threshold with up to 20 mm displacement and 20° misalignment in bovine tissue and FEM simulations.
