BME 281
The brains ability to actively rewire itself in response to external stimuli
Creation of BION microstimulator based on this
Uses FES(Functional
Electrical Stimulation) to send small electric shocks to muscles to induce movement
Small capsule with rechargeable battery, antenna and charging coil for electrical impulses inside
In glass casing with nickel on the ends
2.1 mm diameter, 16 mm long
1791- Luigi Galvani
1960- Liberson’s drop foot stimulator developed
1989-when AMF began work on the microstimulator
2008-AMF develops working prototypes of injectable microstimulators without exoskeletal system
Non profit organization
Main focus in medical research
Have worked on other devices such as :
▪ Cochlear implant (hearing impaired)
▪ Retinal prosthesis (vision)
▪ Fully implantable glucose sensor (diabetes)
Uses FES (Funcional
Electrical Stimulation)
FM device located in motor cortex sends messages in real time down to the relevant muscles
Once the message is received the microstimulator sends out an electrical impulse triggering muscle movement
PREVIOUS NOW/ NEAR FUTURE
~ 750,000 people suffer a stroke every year
~11,000 suffer a spinal cord injury
~500,000 live with cerebral palsy
~270,000 with MS
~5.3 mill with after affects of traumatic brain injury
Small and can be imbedded directly in the affected muscle tissues
Doesn’t just “fix” the problem – it helps reteach the brain how to use the affected area
Can remain safely in the body for up to 80 years
PAST
Surgical procedure
In operating room
PRESENT
BION implantation tool(BIT)
Outpatient office procedure
No surgical tools needed
Consists of long cannula(10 cm)
Cannula made of
Vectra B130-liquid crystal polymer, 30% glass reinforced
Cannula has 2 conduction holes at end of probe
Microstimulators that are temperature and pressure sensitive and also respond to touch
Possibly applying them to next generation prosthetics
Application to lower extremities
