Abstract: An inserter assembly (200) for deploying an intravesical device into a urinary bladder of a patient includes a placement catheter (210), a receiving funnel (220), and a stylet (230). The placement catheter defines a lumen extending from a proximal catheter end to an exit opening. The receiving funnel is secured to the placement catheter. The stylet is removably received through the receiving funnel within the lumen. The stylet includes a stylet body and a paddle (238). The stylet body is dimensioned to drive the intravesical device through the lumen and the exit opening into the bladder. The paddle is fixed to the stylet body about the proximal stylet end and is engageable with the receiving funnel. The paddle optionally includes a fitting (242) being lockably engageable with the receiving funnel to removably secure the stylet to the placement catheter.
