Detailed Description

The Altius System is an implanted device designed to electrically block nerve signals and alleviate pain. Use of this device may be associated with providing an effective, mechanism-based yet non-destructive, treatment for managing intractable limb pain in amputees. In a given patient, the Altius System will be deemed effective if treatment results in 50% reduction of pain score for more than 50% of all pain episodes.

Notice

Study information shown on this site is derived from ClinicalTrials.gov (a public registry operated by the National Institutes of Health). The listing of studies provided is not certain to be all studies for which you might be eligible. Furthermore, study eligibility requirements can be difficult to understand and may change over time, so it is wise to speak with your medical care provider and individual research study teams when making decisions related to participation.
