LivaNova Demonstrates 84.5% Cumulative Response Rate with PolySync Programming in OSPREY Study for Obstructive Sleep Apnea
– Presentation at SLEEP 2026 illustrates ability to convert non-responders into responders using personalized programming
The results build on LivaNova’s previously reported outcomes from the OSPREY randomized controlled trial (RCT), which reported a 65% responder rate in the treatment arm after 12 months of pHGNS therapy delivered by the Company’s aura6000™ System. In the PolySync substudy, patients who did not meet responder criteria after one year of individual-contact stimulation in OSPREY underwent reprogramming using simultaneous-contact stimulation. This approach converted the majority of these patients into responders, significantly improving both AHI and oxygen desaturation index (ODI) outcomes and increasing the cumulative response rate to 84.5%.
“These results underscore the strength of our underlying therapy and the opportunity to further enhance outcomes through innovation,” said
The PolySync findings extend the strong clinical foundation established by LivaNova’s OSPREY and THN3 RCTs, the first RCTs in hypoglossal nerve stimulation (HGNS). As previously reported, OSPREY met its primary safety and efficacy endpoints at six months, demonstrating significant reductions in AHI and ODI, with continued improvements through 12 months of therapy. The full dataset, published in Annals of Internal Medicine, confirmed clinically meaningful and sustained improvements across both objective measures and patient-reported outcomes, including daytime sleepiness and functional quality of life.
PolySync builds on LivaNova’s differentiated pHGNS platform, which utilizes a six-contact electrode positioned on the proximal hypoglossal nerve, prior to any nerve branching, to enable broader access to airway muscles and flexible therapy optimization. By enabling simultaneous-contact stimulation, PolySync expands the variety and number of possible stimulation fields, allowing for broader and more flexible activation of lingual muscles and improved treatment responsiveness across a heterogeneous patient population.
“These data are particularly meaningful because they demonstrate that this novel stimulation paradigm can further improve outcomes beyond that achieved with the initial response to therapy,” Schwartz said. “The ability to convert non-responders into responders through optimized programming represents an important advancement in treating Obstructive Sleep Apnea.”
PolySync programming was well tolerated, with no serious treatment-emergent adverse events and no stimulation- or device-related adverse events reported in the substudy.
“The progression from strong 12-month response rates to even higher cumulative outcomes highlights the clinical potential of this platform and its ability to address a broader patient population,” said
In addition to the PolySync substudy,

Together, these data and presentations highlight LivaNova’s continued investment in advancing neuromodulation science and expanding treatment options for the large and growing population of patients with OSA.
pHGNS is an FDA-approved therapy designed to improve airway patency during sleep by stimulating tongue muscles to prevent upper airway collapse. LivaNova’s multi-contact architecture enables a broad range of programmable configurations, supporting more precise, individualized therapy. The addition of PolySync programming demonstrates how advanced algorithms can further enhance outcomes and extend the benefits of therapy to more patients.
