Abstract

A design and method of manufacture are disclosed for a cavity measurement device used during surgical procedures. The cavity measurement device includes an inflation tube assembly comprising an elongated tube having a distal end and a proximal end and a balloon mounted at the distal end of the elongated tube. The elongated tube and the balloon comprise dissimilar materials and include an adhesive free seal between the elongated tube and the balloon. The inflatable balloon is inserted into a cavity and inflated with a volume of fluid, whereby the balloon volume represents the cavity volume. The mechanical attachment of the balloon onto the tube is substantially leakproof and has an attachment strength greater than the balloon material tensile strength. The mechanical attachment of the present invention substantially eliminates the potential for bond separation and preparatory operations typically associated with adhesive bonds.
