| Abstract: |
A dilator formed with a truss with a pair of spaced-apart end surfaces that provides a restoring force therebetween if forced toward one another, this restoring force provided by a resilient band extending between the opposite ends of the truss with a plurality of notches at each end thereof. The notches exceed at least a third of the thickness of the band. A second and similar band may also be provided in the truss.

First Claim:
Show all 12 claims |
What is claimed is:
1. A dilator capable of introducing separating stresses in anatomical outer wall tissues, said dilator comprising:
- a truss having a pair of spaced apart end surfaces terminated by end edges at opposite ends of said truss and having means for generating restoring forces including at least a first resilient band of selected thickness in said truss extending between said end edges such that, if said spaced apart end surfaces are forced toward one another from initial positions to thereby substantially reduce direct spacing therebetween by a spacing reduction force external to said truss, restoring forces result in said truss which tend to restore said direct spacing between said end surfaces with such restoring forces being due to at least said first resilient band, and further having means for reducing said restoring forces at selected portions of said first resilient band comprising a plurality of notches formed at selected locations along said truss and extending inwardly from at least one side thereof, said notches reducing that thickness of said first resilient band occurring at each said selected location to less than those thicknesses occurring immediately on either side of each said notch; and
- an engagement means adhered to said end surfaces adapted for engaging exposed surfaces of outer wall tissues, and for remaining so engaged against said restoring forces.
