摘要： Devices and methods for delivering treatment fluids or particulates such as, stem cells, drugs, Botox and like, to an inner lining of a bladder for treatment of urinary tract disorders, including over active bladder. A balloon delivery system can include an inflation balloon having a plurality of micro-needles configured to pierce and otherwise puncture an inner bladder wall so as to deliver the treatment fluid to bladder tissue. The treatment fluid can be directly injected into the bladder tissue using the micro needles. Alternatively, the micro needles can be fabricated of bioabsorbable or bioresorbable materials such that the micro needles can remain embedded within the bladder tissue to deliver the treatment fluid or particulate.
