Voiding event identification based on patient input
First Claim
1. A method comprising:
- receiving a sensor signal that varies as a function of a parameter associated with a voiding event of a patient;
detecting, with a processor, the voiding event based on the sensor signal;
receiving, with an implantable input mechanism, input from the patient after detection of the voiding event by the processor, wherein the input comprises a patient defined action that is received via the implantable input mechanism;
associating, with the processor, the input with the detected voiding event; and
determining, with the processor, whether the voiding event was a controlled event or an involuntary event based on the input associated with the voiding event.

Abstract
An implantable medical device (IMD) is configured to operate as an automatic voiding diary for logging urinary and/or fecal voiding events. The IMD detects urinary and/or fecal voiding events and generates data that identifies detected events as voluntary or involuntary events. In particular, the IMD generates the identification data based on a patient defined action. In one embodiment, the patient defined action is the patient tapping on the skin located above the IMD. The IMD may generate the identification data based on one or more characteristics of the tapping, e.g., the number, frequency, duration, or pattern of taps. The IMD may also generate the identification data based on a lack of input during a specific range of time after a detected voiding event. In some embodiments, the identification data may be used to identify a false positive, i.e., an event that was incorrectly detected by the IMD.

20. A. system comprising:
-
a sensor that generates an electrical signal that varies as function of a parameter associated with a voiding event of a patient; a processor that processes the electrical signal to detect the voiding event; and an implantable input mechanism configured to receive an input from the patient after detection of the voiding event by the processor, the input comprising a patient defined action, wherein the processor associates the input with the detected voiding event and determines whether the voiding event was a controlled event or an involuntary event based on the input associated with the voiding event. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33)

34. A non-transitory computer-readable medium comprising instructions that cause a processor to:
-
receive a sensor signal that varies as a function of a parameter associated with a voiding event of a patient; detect the voiding event based on the sensor signal; receive, with an implantable input mechanism, input from the patient after detection of the voiding event by the processor, wherein the input comprises a patient defined action that is received via the implantable input mechanism; associate the input with the detected voiding event; and determine whether the voiding event was a controlled event or an involuntary event based on the input associated with the voiding event.
