Essential Tremor
Device: Activa RC
Phase 4

Study Type: Interventional
Study Design: Endpoint Classification: Safety Study

Primary Outcome Measures:
  • Identify the Rate of User-related Battery Depletion Adverse Events Per Subject-month Requiring Intervention by a Health Care Professional (HCP) and/or the HCP's Designee, Within the First 3 Months of the Activa RC System Being Turned ON. [ Time Frame: 3 months ] [ Designated as safety issue: Yes ]
    Subject-months of follow-up were defined as the time from device activation to the earlier of a subject's 3-month visit or until the subject exited from the study. Any user-related battery depletion adverse events requiring intervention by a health care professional (HCP) and/or the HCP's designee were collected. The event rate per 100 subject-months of follow-up is defined as the number of user-related battery depletion events divided by the total subject follow-up months through the 3-month visit, all multiplied by 100.

Arms Assigned Interventions
Experimental: Patients receiving an Activa RC implant Device: Activa RC
Patients receiving Activa RC as their first implantable neurostimulator or as a replacement implantable neurostimulator for deep brain stimulation


Ages Eligible for Study:   7 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Patient is enrolled in the Implantable Systems Performance Registry (ISPR) and will receive one Activa RC as their first implantable neurostimulator or as a replacement implantable neurostimulator for DBS.
  • Patient must meet the indications in the Activa RC labeling.
  • Patient (or patient's legally authorized representative) signs and dates the appropriate RECHARGE Informed Consent Form and/or Informed Assent Form and Authorization to Use and Disclose Health Information (HIPAA, US only).
  • Patient has a diagnosis of Parkinson's Disease, Essential Tremor, or dystonia that meets the approved indication for Activa RC in the applicable geography.
  • Patient with dystonia is 7 years of age or older (EU only).
  • Patient with either PD or ET is 18 years of age or older.
  • Patient (or caregiver) is able to use the patient programmer and correctly interpret the icons.
  • Patient (or caregiver) is able and willing to regularly monitor the status of the rechargeable battery and respond appropriately.
  • Patient (or caregiver) is able to locate the INS, position the recharge antenna for sufficient coupling, put on the recharge holster/belt, and monitor progress during the recharge session.
  • Patient (or caregiver) is able to perform recharging activities for sufficient duration and frequency to maintain therapy and to perform recharging activities on an ongoing basis.
  • Patient is willing and able to comply with protocol requirements.

Exclusion Criteria:

  • Patient has a contraindication identified in the Activa RC labeling.
  • Patient who is currently enrolled in or plans to enroll in any concurrent drug and/or device study that may confound the results of the RECHARGE study.
  • Patient has or will be implanted with a non-Medtronic Deep Brain Stimulation system component.
