Patent ID: 7182773

Claim:
A method of assembling a cavity measurement device comprising the steps of: attaching a silicone balloon having a tubular stem section and a bulbous portion onto an elongated tube by sliding said stem section onto a distal end of said elongated tube; positioning a heat-shrink tube over an area of said stem section overlying said elongated tube; shrinking said heat-shrink tube; folding a length of said stem section over said heat-shrink tube; overlaying a compression tube onto an overtube to create an overtube assembly; mounting said overtube assembly onto a section of said elongated tube, the stem section length folded over said heat-shrink tube, and the stem section overlying said elongated tube; heating and subsequently cooling said overtube assembly whereby said overtube forms a mechanical attachment to said stem section folded over said heat-shrink tube and overlying said elongated tube; and securing a proximal end of said overtube onto said elongated tube.
