- IDE application: BION Active Seating for Pressure Ulcer Prevention Page 65
- Subject is malnourished.
- The attending physician has concerns about the healing of this subject (e.g.: heavy smoking, excessive and/or poorly-managed incontinence).
- Subject has concurrent concomitant condition affecting the buttock/pelvic area, including other pressure wound not corrected by the flap surgery.
- Subject suffers from claustrophobia or fear of MRI, or has any contraindication to MRI (e.g. metal implants, pacemaker, etc. not suited to MRI).
- Subject has damage to the inferior or superior gluteal neurovascular pedicles.
- Subject is / plans to participate in another investigational study that may affect the healing of PUs or prevent their occurrence/recurrence.
- Subject is using medications / undergoing procedures that will interfere with NMES effecting muscle contraction (e.g. treatments for spasticity and / or spasms, such as: neurotomies, tenotomies, myotomies, and rhizotomies; as well as tranquilizers and muscle relaxant / paralyzing agents such as Baclofen (Lioresal®), Dantrolene (Dantrium®) and Botulinum Toxin Type A (Botox®)).
- Subjects whose ulcer extends more than 2.25" deep to the projected surface contour of the buttock when the patient is in a prone position (measured perpendicular to the base of the PU, from the deepest point of the PU to the level of the highest point of the buttock surface, when prone)
- Subject's wheelchair and the BION system have been tested for interference of either with the other's operation, and either does not operate normally when used together, and this cannot be resolved with an available alternate wheelchair.
