Bladder neck is the tissue where a urinary catheter meets the resistance of the internal urethral sphincter as it passes, and where the catheter balloon seats once it is inflated.

Materials

Material Visual Tactile Simulator Notes
SLA resin Urinary Catheterization Simulator (Gillis) Passing a catheter through the valve gives a slight resistance the authors describe as "representative of breaching the internal urethral sphincter on a real patient".[1]
