Abstract
Abstract A one-piece aneurysm clip formed from an elongated spring metal ribbon having a central helical portion, diverging first connecting portions extending from the helical portion, and converging second connecting portions extending from the first connecting portions. The axis of the helical portion extends transversely of a major crosswise axis of the ribbon. The jaws are turned 90 degrees from the plane of the helical portion and are arranged to engage flatwise, spring action of the helical portion urging the jaws to engaged position.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
133 words
A one-piece aneurysm clip having an elongated flat ribbon body having major and minor crosswise axes and including a central helical portion joining diverging first connecting portions extending from the helical portion, converging second connecting portions extending from the first connecting portions with the major crosswise axes of said helical, first and second connecting portions being substantially parallel to a first plane and said plane extending transversely of the axis of said helical portion, and jaws extending from the converging second connecting portions, the jaws being arranged so each of the flat faces thereof parallel to the major crosswise axes of the said jaw portions are engageable flatwise and lie in a plane which is not parallel to said first plane, spring action of the helical portion urging the jaws to engaged position.
Claim 2
Dependent Claim
133 words
A one-piece aneurysm clip having an elongated flat ribbon body having major and minor crosswise axes and including a central helical portion joining diverging first connecting portions extending from the helical portion, converging second connecting portions extending from the first connecting portions with the major crosswise axes of said helical, first and second connecting portions being substantially parallel to a first plane and said plane extending transversely of the axis of said helical portion, and jaws extending from the converging second connecting portions, the jaws being arranged so each of the flat faces thereof parallel to the major crosswise axes of the said jaw portions are engageable flatwise and lie in a plane which is not parallel to said first plane, spring action of the helical portion urging the jaws to engaged position.
Claim 3
Dependent Claim
19 words
A one-piece aneurysm clip as in claim 1 wherein the jaw portions are turned 90* from the helical portion.
