MAUDE Adverse Event Report: BOSTON SCIENTIFIC NEUROMODULATION VERCISE GENUS; STIMULATOR, ELECTRICAL, IMPLANTED, FOR PARKINSONIAN SYMPTOMS

Model Number DB-1216

Device Problems High impedance (1291); Unexpected Therapeutic Results (1631)

Patient Problems Movement Disorder (4412); Speech Disorder (4415); Unspecified Musculoskeletal problem (4535)

Event Date 09/18/2023

Event Type  Injury  

Event Description

It was reported the patient experienced a return of their pre-implant bradykinesia, rigidity, and slowness of speech.The physician observed the presence of high impedance measurements.The patient underwent a revision procedure where the implantable pulse generator (ipg) was replaced.

Manufacturer Narrative

The returned ipg was linked to a clinician programmer (cp) and high impedance measurements were observed.X-ray inspection of the ipg revealed a fractured feedthru ground wire.Engineers concluded the cause of the high impedances and the resulting impact to the patient therapy was the result of the fractured/broken proximal feedthru wire that connects to the case of the ipg.If the proximal feedthru wire that is connected to the case is compromised, stimulation capability will be compromised (as well as mri immunity) and monopolar impedance measurements will report high.
