This manual provides information about the Axonics Sacral Neuromodulation (SNM) System tined lead (Model 1201 and 2201) and the lead implantation procedure. The tined lead can be used with the Axonics Model 1101 Neurostimulator and Model 1601 Trial Stimulator.

2005年6月30日 · The use of a new tined lead electrode for sacral neuromodulation (SNS) was evaluated in a European study including 127 patients with chronic voiding dysfunction. The tined lead can be implanted during the first stage of the SNS procedure, which makes a longer test period possible before implanting the pulse generator in a second stage.

Lead migration is a common cause of loss of efficacy in sacral nerve modulation. Our aim was to systematically study the migration pattern of tined leads in sacral nerve modulation. Our hypothesis was that tined leads may promote forward migration ...

2018年1月16日 · The Axonics tined lead measures 30 cm with four similarly sized and spaced electrodes to the InterStim lead (Figure 8A). The Axonics tines are uniquely designed in a helical fashion (Figure 8 B). My experience is the helical tines allow for a smoother deployment as the dilation sheath is removed.

Two-stage testing with the tined lead seems more reliable than the classic percutaneous nerve evaluation. The lead anchoring method seems sufficient for fixing the electrode in the medium term. This new minimally invasive approach gives positive results in the medium term.

2020年9月10日 · Sacral neuromodulation with the tined lead procedure is a safe and effective treatment for patients with overactive bladder symptoms or urinary retention.

The tined lead connects to a stimulation device, which creates a series of electrical pulses to stimulate the S3 or S4 sacral nerve. A set of accessories, including procedure-specific surgical tools, Axonics Model 1801, and stimulation cables, and

Results: Successful tined lead procedures were achieved in 33 of 35 patients (94%) implanted with the curved stylet compared with 13 of 20 patients (65%) implanted with the straight stylet (P = 0.005). Intention-to-treat analyses at 12 and 24 months showed success rates of 94% and 91%, respectively, in the curved stylet group vs 65% and 45% ...

2022年3月16日 · • Neurostimulator Model 4101 (Recharge free) with Tined Lead Model 1201/2201 Non-clinical testing has demonstrated that the Axonics SNM System implants, i.e. the Neurostimulator (Models 1101 and 4101) and Tined Lead (Model 1201/2201), are MR Conditional .

The introduction of the tined lead as permanent lead for a two-staged implant procedure and other technical and surgical improvements make sacral neuromodulation with InterStim™ Therapy a useful treatment modality in the urologic field.
