Cooley Mitral Valve Dilator 8-15mm

Clinical Application

Used in open cardiac procedures for controlled dilatation of a stenotic mitral valve during mitral commissurotomy and valve repair. The instrument permits incremental enlargement of the valve orifice under direct vision, allowing the surgeon to relieve commissural fusion while preserving leaflet tissue when possible. It is intended for use in adult and adolescent mitral pathology where graded dilation between 8 and 15 mm is required.

Design & Configuration

The Cooley design provides a graduated dilator geometry that spans 8–15 mm, enabling stepwise expansion without exchanging multiple single‑size rods. A slim shaft profile facilitates atraumatic insertion through a left atriotomy or transseptal approach and gives the surgeon tactile feedback during commissural separation. The compact footprint and single-instrument sizing range reduce instrument changes and help maintain operative efficiency in valve procedures.
