Transmembrane sensing device for sensing bladder condition
First Claim
1. A method comprising:
- sensing a condition within an interior of a bladder from a position within the interior of the bladder via a sensor carried on a distal end of a lead and positioned within the interior of the bladder, the lead having an electrical conductor therein and extending, via penetration of a wall of the bladder, from the interior of the bladder to a sensing device implanted outside of the bladder;
generating, via a processor within the sensing device, information based on the bladder condition within the interior of the bladder sensed by the sensor from the position within the interior of the bladder; and
delivering, via an implantable stimulator, electrical stimulation therapy based on the information.

Abstract
The disclosure describes a sensing device that is implantable to sense bladder conditions, as well as a neurostimulation system and method that make use of such a sensor for alleviation of urinary incontinence. The sensing device is implantable outside the bladder, but includes a lead that penetrates the bladder wall to deploy a sensor within the bladder. Using the sensor on the lead, the sensing device outside the bladder is able to detect a condition within the interior of the bladder. In this sense, the sensing device provides transmembrane sensing of internal bladder conditions. The condition may be indicative of bladder filling or bladder contraction, and may be used to control electrical stimulation applied to the patient to alleviate urinary incontinence.
