Avery Biomedical in Portugal: diaphragm pacing and phrenic nerve stimulation
Interphysix officially represents Avery Biomedical, manufacturer of the Avery Diaphragm Pacing System, an implantable phrenic nerve stimulation system for chronic ventilatory support in carefully selected patients.
This is a highly specific clinical area. Our role is to help hospital teams, respiratory care, neurology, paediatrics, rehabilitation and surgical teams frame the indication, gather technical documentation and coordinate with Avery Biomedical.
Information for healthcare professionals. Eligibility for diaphragm pacing depends on clinical assessment, phrenic nerve, diaphragm and lung function, and the decision of the responsible medical team.
Avery system with external transmitter, antennas, implanted receivers and electrodes for phrenic nerve stimulation.
What is the Avery system?
The Avery Diaphragm Pacing System is a diaphragm pacing system. It stimulates the phrenic nerve to contract the diaphragm and support a more physiological breathing pattern in chronic ventilatory insufficiency of neurological or central origin.
No percutaneous wires
Receivers and electrodes are implanted; power and signals are transmitted by external antennas placed over the receivers.
External control
The transmitter supports parameter control, audio/visual alarms and bilateral operation, with safety as a core requirement.
Clinical indication
The system is relevant only when phrenic nerve, diaphragm and lung function can accommodate electrical stimulation.
When can assessment make sense?
Avery Biomedical positions the system for patients who require chronic ventilatory support and may benefit from phrenic nerve stimulation, subject to specialist medical assessment.
- High cervical spinal cord injury with loss of respiratory control and preserved peripheral function.
- Congenital central hypoventilation syndrome or other central hypoventilation conditions.
- Central sleep apnea or central ventilatory insufficiency in selected contexts.
- Diaphragm paralysis when neurophysiological and surgical assessment supports the indication.
How Interphysix helps
Technical triage
We clarify the clinical context, responsible team, request objective and initial documentation.
Avery coordination
We route technical questions, forms, assessment requirements and clinical information to the right team.
Hospital process
We support quotations, procurement documentation, timelines, configuration and local commercial contact.
Continuity
We follow accessories, consumables, post-implementation support and manufacturer information requests.
Frequently asked questions
Does Avery always replace mechanical ventilation?
No. Diaphragm pacing is an option for selected cases and does not automatically remove the need for a ventilator, tracheostomy or additional support. The decision is clinical.
Which team should be involved?
Usually respiratory medicine, neurology or neuro-rehabilitation, appropriately experienced surgery, intensive care or home ventilation teams, depending on the case.
What should be sent first?
Medical team contact, diagnosis, current ventilatory support, clinical objective, relevant examinations and the main question. Interphysix helps organise the request before involving Avery.
Do you have a case or project to assess?
Send us the clinical context and responsible team. We will reply with the appropriate technical-commercial next step and documentation.
