Medical device complications

Bladder/Sacral Nerve Stimulators

• Single wire system inserted into the S3 sacral foramen to stimulate sacral nerve and treat urinary incontinence

Complications

1. Infection (early or late complication)
2. Lead Migration
3. Stimulator misfiring

Deep Brain Stimulators

• Implanted to treat Parkinson's disease and dystonia.
• Single lead systems implanted into the thalamus

Complications

1. Infection (usually early after placement)
2. Over or Under stimulation
3. Lead Migration

Gastric Pacemakers

• Inserted into the gastric musculature for gastroparesis management

Complications

1. Perforation
2. Infection
3. Lead Migration

Phrenic Nerve/Diaphragmatic Stimulators

• Implanted into bilateral phrenic nerves to treat rerspiratory insufficiency from poor diaphragmatic motion

Complications

1. Pneumothorax (early after implantation)
2. Infection
3. Wire Migration
4. Drive malfunction (causing diaphragmatic paralysis)
