Abstract
Abstract A vessel ligature constituted by a tape applied around a vessel by means of a hemostat adapted to pass under the vessel, engage the tape, and draw the engaged tape back below the vessel, the tape ends being then passed through an elongated wire loop and drawn with the loop into a plastic sleeve, the sleeve being slidable over the wire loop and along the tape toward the vessel to tighten the bight of the tape around the vessel, and the bight being maintained in vessel-closing position by means of a hemostat clamped on the plastic sleeve and/or tape at a distance from the vessel; and the method including said steps.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
72 words
A vessel ligature or clamp applicator comprising an elongated wire element terminating at one end in an integral loop, a piece of plastic tubing shorter than said element and fitted thereon, said tubing being slidable past said loop onto a piece of tape having both its ends passed through said loop, the plastic tubing being further slidable along said tape and a handle fixed to the opposite end of said wire element.
Claim 2
Dependent Claim
72 words
A vessel ligature or clamp applicator comprising an elongated wire element terminating at one end in an integral loop, a piece of plastic tubing shorter than said element and fitted thereon, said tubing being slidable past said loop onto a piece of tape having both its ends passed through said loop, the plastic tubing being further slidable along said tape and a handle fixed to the opposite end of said wire element.
Claim 3
Dependent Claim
38 words
A vessel ligature or clamp applicator according to claim 1 in which the elongated wire element is a wire doubled on itself adjacent its middle, and in which the handle is affixed to both ends of said wire.
Claim 4
Dependent Claim
30 words
A vessel ligature or clamp applicator according to claim 2 in which the wire loop is curved to form an opening through which the tape ends can readily be passed.
Claim 5
Dependent Claim
109 words
A vessel ligature and applicator assembly comprising an elongated wire element terminating at one end in an integral loop, a piece of plastic tubing shorter than said element and fitted thereon, said tubing being slidable past said loop, a handle fixed to the opposite end of said wire element, and a piece of tape having Two ends adapted to be doubled on itself around a vessel to be ligated, the end portions being engaged in the loop and adapted to be drawn through the tubing by relative sliding movement of the tubing and the wire element and to be released from the loop when the tubing is slid therefrom.
Claim 6
Dependent Claim
109 words
A vessel ligature and applicator assembly comprising an elongated wire element terminating at one end in an integral loop, a piece of plastic tubing shorter than said element and fitted thereon, said tubing being slidable past said loop, a handle fixed to the opposite end of said wire element, and a piece of tape having Two ends adapted to be doubled on itself around a vessel to be ligated, the end portions being engaged in the loop and adapted to be drawn through the tubing by relative sliding movement of the tubing and the wire element and to be released from the loop when the tubing is slid therefrom.
Claim 7
Dependent Claim
46 words
A vessel ligature and applicator assembly according to claim 4 in which the plastic is of a soft composition and is adapted, by sliding along the double tape, to tighten the bight of the tape around the vessel with minimum danger of damage to the vessel.
