TRANSMEMBRANE SENSING DEVICE FOR SENSING BLADDER CONDITION
First Claim
1. A method comprising:
- sensing a bladder condition via a sensor carried on a distal end of a lead, the sensor positioned within an interior of the bladder, the lead having an electrical conductor therein, and the lead extending from the interior of the bladder to a sensing device implanted outside of the bladder via penetration of a wall of the bladder; and
delivering stimulation therapy for urinary incontinence from an implantable stimulator based on the sensed bladder condition.

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.

10. An implantable electrical stimulation system comprising:
-
a sensing device adapted to be implanted outside of a bladder; a lead having an electrical conductor therein and adapted to extend from the sensing device into an interior of the bladder via penetration of a wall of the bladder; a sensor, adapted to be carried at a distal end of the lead and positioned within the interior of the bladder, that senses a condition within the interior of the bladder; a processor within the sensing device that generates information based on the sensed bladder condition; and an implantable stimulator that delivers electrical stimulation therapy based on the information. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
