Gerbode Mitral Valve Dilator 9-45mm

Clinical Application

This instrument is intended to dilate the mitral valve annulus intraoperatively to restore effective valve orifice area during procedures such as closed or open commissurotomy and certain valve repair interventions. The continuous 9–45 mm range allows the surgeon to select incremental dilation appropriate to annular size and pathology, aiding assessment of leaflet coaptation and hemodynamic competence while minimizing repeated instrument exchanges.

Design & Configuration

The Gerbode pattern features a tapered annular dilating geometry that permits gradual, controlled expansion of the mitral orifice. The graduated configuration covering 9–45 mm reduces the need for multiple discrete dilators by providing a continuous or smoothly stepped dilation range, which helps the surgeon titrate dilation to tissue response. The tapered tip and ergonomic handle design support predictable seating within the valve orifice and controlled force application to limit trauma to leaflets and subvalvular apparatus.

Instrument Specifications

• Instrument type: Mitral valve dilator (Gerbode pattern)
• Dilating range: 9–45 mm
• Configuration: Graduated/tapered annular dilator for intraoperative use
• Clinical use: Commissurotomy and mitral valve repair procedures
• Reusable construction suitable for standard sterilization workflows

Material & Construction

Manufactured from surgical-grade stainless steel for corrosion resistance and durable performance through repeated sterilization cycles. The shaping and finish are optimized to allow atraumatic contact with valvular tissue while maintaining tactile feedback during dilation. Reusable construction supports standard high-level disinfection and steam sterilization processes when followed by validated facility protocols.

Quality & Compliance

Manufactured by FDA-registered OEM facilities and produced under strict quality control standards.

Brand Comparison

Comparable in form and function to equivalent instruments offered by major US medical suppliers.
