Fabrication of Murine Ventricular Balloons for the Langendorff Heart Preparation.

A method for fabrication of ventricular pressure balloons is presented. Murine ventricular balloons with adequately small size, durability and elastic characteristics were produced using silicone dispersion. The forms, onto which the silicone are coated, are constructed of water soluble materials allowing the release of cured silicone balloons with soaking in H(2)O.
