Abstract

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.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 87 words
An inflation tube assembly comprising: an elongated tube having a distal end and a proximal end, a balloon mounted at said distal end of said elongated tube; said elongated tube and said balloon comprising dissimilar materials; an adhesive free seal between said elongated tube and said balloon, wherein said adhesive free seal includes a shrinkable tube encircling said balloon and said elongated tube, and a secondary layer over said shrinkable tube, and wherein said secondary layer includes a portion of said balloon layered over said shrinkable tube.
Claim 2
Dependent Claim 87 words
An inflation tube assembly comprising: an elongated tube having a distal end and a proximal end, a balloon mounted at said distal end of said elongated tube; said elongated tube and said balloon comprising dissimilar materials; an adhesive free seal between said elongated tube and said balloon, wherein said adhesive free seal includes a shrinkable tube encircling said balloon and said elongated tube, and a secondary layer over said shrinkable tube, and wherein said secondary layer includes a portion of said balloon layered over said shrinkable tube.
Claim 3
Dependent Claim 18 words
An inflation tube assembly as set forth in claim 1 , wherein said elongated tube is a thermoplastic.
Claim 4
Dependent Claim 17 words
An inflation tube assembly as set forth in claim 1 , wherein said balloon is a silicone.
Claim 5
Dependent Claim 23 words
An inflation tube assembly as set forth in claim 1 , wherein said balloon includes a tubular stem portion and a bulbous portion.
Claim 6
Dependent Claim 19 words
An inflation tube assembly as set forth in claim 1 , wherein said shrinkable tube is a polyvinylid fluoride.
Claim 7
Dependent Claim 28 words
An inflation tube assembly as set forth in claim 1 , wherein said adhesive free seal further includes an overtube surrounding said secondary layer and said shrinkable tube.
Claim 8
Dependent Claim 18 words
