Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
139 words
In an apparatus for closing tubular anatomical vessels, an applicator comprising: opposed jaws adapted to receive between them a clamp forming means comprising a pair of complementary metal strips, one of plain ribbon form and the other of channel cross section having longitudinally extending side flanges between which said ribbon-form strip is receivable; means to guide strips longitudinally through said applicator and toward the tips of said jaws; opposed cutter teeth on said jaws adapted to shear off successive lengths of said strips to constitute successive pairs of opposed clamping elements; and means on said jaws to bend respective side flange portions of the channel section clamping elements over the side margins of opposed ribbon-form clamping elements so as to lock the opposed clamping elements together with the vessel extending transversely between the intermediate portions of said clamping elements.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
52 words
Apparatus as defined in claim 1 wherein said applicator is in the form of tongs including a pair of handles extending integrally from the respective jaws and a pivot connecting said handles; and means on said handles for guiding the respective strips past said pivot and into the space between said jaws.
Claim 4
Dependent Claim
65 words
APparatus as defined in claim 1, wherein one of said jaws has a longitudinally extending channel recess for receiving and supporting the channel section of said other strip; and the other jaw has a pair of laterally spaced folding lips engageable with the flanges of said other strip and operable to fold them over the side margins of said one strip of plain ribbon form.
Claim 5
Dependent Claim
34 words
Apparatus as defined in claim 2, wherein said folding lips are provided with transversely opposed notches to receive an anatomical vessel between longitudinally spaced areas of folding of said flanges over said one strip.
