A small luminal device intended to be fitted onto a syringe (not included) to allow for administration of fluids (e.g., pharmaceuticals) into the bladder (intravesical) via the urethra. It includes a short tip intended to be inserted into the urethra with a flange intended to prevent leakage/backflow during instillation. It is intended for use on both male and female patients as an alternative to urethral instillation via a catheter. This is a single-use device.
