Abstract
Abstract A one-piece vascular clip which includes a central helical spring section, first connecting sections joined by the spring section, second connecting sections extending from the first connecting sections to cross. First jaw sections extend from the second connecting sections. A return bend jaw section extends from each of the first jaw sections parallel and adjacent to the associated first jaw section. A horn extends outwardly from each of the return bend jaw sections.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
146 words
A one-piece vascular clip formed from a length of spring wire which comprises a central helical spring section, first connecting sections joined by the spring section, second connecting sections extending from the first connecting sections and crossing, first jaw sections extending from the second connecting sections, a respective return bend jaw section extending from each of the first jaw sections parallel and adjacent to the associated first jaw section, and a horn extending outwardly from each of the return bend jaw sections, each of the return bend jaw sections being coplanar with the associated first return bend jaw section and the associated horn, the horns being engageable with the second connecting sections to preclude the jaw contacting portions of the jaws from advancing beyond their contact plane when laterally misaligned into non-opposed relation to maintain the jaw sections and the return bend jaw sections in alignment.
Claim 2
Dependent Claim
146 words
A one-piece vascular clip formed from a length of spring wire which comprises a central helical spring section, first connecting sections joined by the spring section, second connecting sections extending from the first connecting sections and crossing, first jaw sections extending from the second connecting sections, a respective return bend jaw section extending from each of the first jaw sections parallel and adjacent to the associated first jaw section, and a horn extending outwardly from each of the return bend jaw sections, each of the return bend jaw sections being coplanar with the associated first return bend jaw section and the associated horn, the horns being engageable with the second connecting sections to preclude the jaw contacting portions of the jaws from advancing beyond their contact plane when laterally misaligned into non-opposed relation to maintain the jaw sections and the return bend jaw sections in alignment.
Claim 3
Dependent Claim
41 words
A vascular clip as in claim 1 in which each return bend jaw section is attached to the associated first jaw section by means spaced from the place where the return bend jaw section extends from the associated first jaw section.
Claim 4
Dependent Claim
33 words
A one-piece vascular clip as in claim 1 in which the central helical spring section includes a single convolution and that each return bend jaw section is opposite an opposed first jaw section.
