Multicenter Study
A prospective, multicenter study of a novel, miniaturized rechargeable sacral neuromodulation system: 12-month results from the RELAX-OAB study.
Historically, providing SNM therapy required use of a non-rechargeable implantable pulse generator (IPG) with an average device lifespan of 4.4 years. Multiple device replacement surgeries are necessary with this device for long-term overactive bladder (OAB) management. A longer-lived device can reduce and potentially eliminate the need for replacement surgeries, thereby improving the long-term safety and cost-effectiveness of SNM therapy. The objective of this study was to evaluate the safety and efficacy of a miniaturized, rechargeable SNM system. ⋯ The Axonics r-SNM System provides sustained clinically significant improvements in OAB subjects after 1-year. Subjects were satisfied with r-SNM therapy and reported an easy and acceptable recharging experience.
