Model Number 103
Event Date 04/07/2010
Event Type  Injury  
Event Description

It was initially reported that a pt was experiencing urinary retention as a result of a change in the pt's duty cycle for stimulation. The pt was previously noted to be experiencing larynx constriction caused by the stimulation when she was programmed to higher than 0. 75ma. At this time the pt's duty cycle was adjusted to accommodate for the intolerable higher settings. The pt was known to be experiencing efficacy from the duty cycle with the lower output current. Her physician ran some tests (specifics are not known), and it was observed that when the device was disabled, the pt was able to urinate properly. The physician has changed the stimulation off-time to see if this will resolve the issue and still maintain the seizure control. There is no other known cause for the event. The pt's diagnostic tests are said to be within normal limits, but no specifics were made available. The pt is expected to return to the physician for follow-up on the issue.
