Brief Summary
The goal of this clinical investigation is to learn about the use of a novel medical device, the SPIRION Laryngeal Pacemaker, in patients suffering from bilateral vocal fold paralysis (BVFP). The main questions it aims to answer are:
- Is the use of the device safe?
- Does the device improve the participants ability to take a breath? Participants will be implanted with the SPIRION Laryngeal Pacemaker and the development of their symptoms will be observed for the following 2 years.

Interventions
Timeline of Visits * Screening * Baseline: Official baseline, assessment primary \& secondary objectives * Implantation of device * Activation \& fitting: Baseline active device; implanted device has just been activated; assessment of secondary objectives only * 8 FU Visits over 2 years after activation; Includes * Baseline Switch Off: results of the visit preceding a 14-day switch-off of the device; assessment of secondary objectives only * Endpoints for * Pivotal phase: 12 months after activation; official endpoint for assessment of primary \& secondary objectives * Active post-pivotal phase: 24-month follow-up; endpoint for all secondary objectives * Switch Off: 2 Visits; assessment of secondary objectives only * Repeated checkpoints to assess device effects over 2 years: 5 visits; assessment of secondary objectives only Device shall increase respiratory patency during inspiration, assessed by normalized PIF; other outcome measures are used to assess secondary objectives
Eligibility Criteria
You may qualify if:
- Between 18 and 75 years old at the time of enrolment (i.e., informed consent form (ICF) signed)
- Diagnosed with BVFP for a minimum of 6 months
- With sufficient autonomous respiratory capacity to maintain their vital functions independently of the SPIRION Laryngeal Pacemaker. Before a permanent closure of the tracheostomy is carried out during this clinical investigation, the Principal Investigator shall confirm that at least at rest, the failure of the SPIRION Laryngeal Pacemaker would not put the patient in a life-threatening condition because of insufficient respiratory patency
- At least one PCA responds to electrical stimulation (clear abduction of the respective VF in response to electrical stimulation) within an Endoscopic Cap Electrode (ECE50) test
- Fluent in German.
You may not qualify if:
- Pregnant or breast-feeding women
- Patients suffering from an ongoing or chronic laryngeal inflammation at the time of enrolment
- Vocal fold immobility caused by arytenoid joint dysfunctions (e.g., arthritis, scarring, etc.), malignancies, central nervous system (CNS) pathologies, and/or systemic diseases
- Patients who underwent previous permanent surgical glottal enlargement
- Patients who underwent any other laryngeal surgeries (e.g., laryngeal framework surgery) that would compromise the correct SPIRION Electrode placement and/or the intended functionality of the SPIRION Laryngeal Pacemaker
- The adductor laryngeal muscles on either or both sides underwent a botulinum toxin injection that is still effective at the time of surgery (i.e., the respective VF position is either in intermediate or lateral position)
- Patients who underwent thoracic surgeries that would compromise at least one of the following procedures:
- Correct placement of the SPIRION Electrode or SPIRION Implant
- Connection of the SPIRION Implant with the SPIRION Electrode
- Connection of the SPIRION Implant with the external SPIRION Processor
- Patients wearing an active implantable medical device at the time of enrolment
- Patients with a clinical history that would suggest a high probability that they would need an MRI
- Patients diagnosed with a malignant disease in the head and neck region
- Patients diagnosed with chronic airway infections or obstructions, or severe respiratory diseases (e.g., chronic obstructive pulmonary disease (COPD) grade II or higher)
- Patients who underwent external beam radiation therapy in the surgical area
