Implantable medical lead including voiding event sensor
First Claim
1. A system comprising:
- a medical lead comprising;
a lead body extending between a proximal end configured to be coupled to a medical device and a distal end,a sensor coupled to the lead body between the proximal end and the distal end, wherein the sensor is configured to generate an electrical signal that varies as a function of a parameter associated with a voiding event of a patient, wherein the voiding event comprises at least one of a urinary voiding event or a fecal voiding event, anda stimulation electrode coupled to the lead body between the proximal end and the distal end; and
a voiding monitor that receives the electrical signal from the sensor and generates voiding information based on the electrical signal.

Abstract
An implantable medical lead includes at least one stimulation electrode and at least one sensor configured to generate an electrical signal that varies as a function of a parameter associated with a voiding event of a patient. In some embodiments, the sensor may be at least one of a microphone that captures sounds associated with voiding events, a pressure sensor, a flow sensor, a strain gauge, a physiological parameter sensing electrode or a temperature sensor. The electrical signal generated by the sensor may used to detect an occurrence of a voiding event. Thus, the lead may be coupled wirelessly or via a wired connection to a device that processes the electrical signal from the sensor, generates voiding information based on the electrical signal, and in some cases, records the voiding information for later retrieval and analysis.
