Abstract
Abstract A medical instrument for measuring tubular vessels and prosthetic grafts therefor comprising: a measuring ring of a diameter corresponding with the diameter of a selected prosthetic graft; an elongated rod attached to the ring; and a handle attached to the rod. The free end of the handle may be of a reduced lateral dimension corresponding with the limb diameter of a bifurcated prosthetic graft.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
58 words
A set of graduated medical instruments for measuring vessels and prosthetic grafts therefor, each of said instruments comprising: a handle member; an elongated rod member attached to said handle member; and a ring member attached to said rod member, said ring being of a diameter corresponding with the diameter of a selected one of said prosthetic vessel grafts.
Claim 2
Dependent Claim
58 words
A set of graduated medical instruments for measuring vessels and prosthetic grafts therefor, each of said instruments comprising: a handle member; an elongated rod member attached to said handle member; and a ring member attached to said rod member, said ring being of a diameter corresponding with the diameter of a selected one of said prosthetic vessel grafts.
Claim 3
Dependent Claim
46 words
A set of medical instruments as set forth in claim 1 in which the handle member of each of said instruments is flat having a thickness substantially less than its width so that said instruments may be closely positioned with each other for compact storage thereof.
Claim 4
Dependent Claim
41 words
A set of medical instruments as set forth in claim 2 in which the handle member of each of said instruments is provided with an aperture through which a keeper member is passed to maintain said instruments together as a set.
Claim 5
Dependent Claim
57 words
A set of medical instruments as set forth in claim 3 in which the width of the end of said handle member opposite said rod member is of a width corresponding with the diameter of the limb portions of a bifurcated prosthetic graft, the aorta diameter of which corresponds with the diameter of said instrument ring member.
Claim 6
Dependent Claim
47 words
A set of medical instruments as set forth in claim 1 in which the lateral dimension of the end of said handle member corresponds with the limb diameter of a bifurcated prosthetic graft, the aorta diameter of which corresponds with the diameter of said instrument ring member.
Claim 7
Dependent Claim
34 words
A set of medical instruments as set forth in claim 5 in which the lateral dimension of said handle member between said end and said rod member is greater than said end lateral dimension.
Claim 8
Dependent Claim
77 words
A medical instrument for measuring tubular vessels and prosthetic grafts therefor comprising: a measuring ring of a diameter corresponding with the diameter of a selected prosthetic vessel graft; an elongated rod attached to said ring; and a handle attached to said rod, the free end of said handle being of a reduced lateral dimension corresponding with the limb diameter of a bifurcated prosthetic graft, the aorta diameter of which corresponds with the diameter of said measuring ring.
Claim 9
Dependent Claim
77 words
A medical instrument for measuring tubular vessels and prosthetic grafts therefor comprising: a measuring ring of a diameter corresponding with the diameter of a selected prosthetic vessel graft; an elongated rod attached to said ring; and a handle attached to said rod, the free end of said handle being of a reduced lateral dimension corresponding with the limb diameter of a bifurcated prosthetic graft, the aorta diameter of which corresponds with the diameter of said measuring ring.
Claim 10
Dependent Claim
26 words
A medical instrument as set forth in claim 7 in which said handle is flat, permitting a number of like instruments to be compactly stored together.
