Abstract
Abstract Apparatus for measuring length in a blood vessel includes an inner barrel slideably fitting within an outer barrel. The apparatus also preferably includes a zero ring for initializing a position of the inner barrel relative to the outer barrel, wherein the zero ring is rotatably positioned on the outer barrel. The apparatus further includes a small-diameter clamp extending outwardly from the inner barrel for holding a catherization mechanism for visualizing a blood vessel, wherein the catherization mechanism includes a marker and a scale is positioned on the inner barrel for indicating a displacement of the inner barrel relative to the outer barrel in response to the catherization mechanism marker.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
119 words
Apparatus for measuring length in a body lumen in conjunction with a catherization assembly having a larger-diameter stationary component and a smaller-diameter moveable component with at least a distal end of the moveable component terminating in a radio-opaque marker, the apparatus comprising: an outer barrel including a large-diameter clamp adapted for retaining the larger-diameter stationary component of the catherization assembly; an inner barrel, slideably disposed within the outer barrel, the inner barrel including a small-diameter clamp adapted for retaining the smaller-diameter moveable component of the catherization assembly; and a scale operative to show a relative position of the inner barrel with respect to the outer barrel, thereby indicating the relative position of the moveable component within the body lumen.
Claim 2
Dependent Claim
119 words
Apparatus for measuring length in a body lumen in conjunction with a catherization assembly having a larger-diameter stationary component and a smaller-diameter moveable component with at least a distal end of the moveable component terminating in a radio-opaque marker, the apparatus comprising: an outer barrel including a large-diameter clamp adapted for retaining the larger-diameter stationary component of the catherization assembly; an inner barrel, slideably disposed within the outer barrel, the inner barrel including a small-diameter clamp adapted for retaining the smaller-diameter moveable component of the catherization assembly; and a scale operative to show a relative position of the inner barrel with respect to the outer barrel, thereby indicating the relative position of the moveable component within the body lumen.
Claim 3
Dependent Claim
39 words
The apparatus of claim 1 , wherein: the catherization assembly includes a guide catheter and a catheter having a radio-opaque marker; the large-diameter clamp retains the guide catheter; and the small-diameter clamp retains the catheter having the radio-opaque marker.
Claim 4
Dependent Claim
29 words
The apparatus of claim 1 , wherein: the catherization assembly includes a catheter and a guidewire; the large-diameter clamp retains the catheter; and the small-diameter clamp retains the guidewire.
Claim 5
Dependent Claim
43 words
The apparatus of claim 1 , further including a zero position wherein a position of the inner barrel is fixed relative to the outer barrel, enabling the catherization assembly to move as a unit to achieve an initial position within the body lumen.
Claim 6
Dependent Claim
25 words
The apparatus of claim 1 , wherein the outer barrel is an elongated member having a cross-sectional diameter allowing the inner barrel to slide therewithin.
Claim 7
Dependent Claim
19 words
The apparatus of claim 1 , wherein the outer barrel includes a slot through which the small-diameter clamp extends.
Claim 8
Dependent Claim
14 words
An apparatus of claim 1 , wherein the outer barrel includes a guidewire hook.
Claim 9
Dependent Claim
29 words
The apparatus of claim 1 , further including a zero ring disposed within a recess in the outer barrel for operatively retaining said inner barrel in an initial position.
Claim 10
Dependent Claim
25 words
The apparatus of claim 1 , wherein both the larger-diameter stationary component and smaller diameter moveable component terminate in distal ends with radio opaque markers.
Claim 11
Dependent Claim
17 words
The apparatus of claim 2 , wherein the catheter having the radio-opaque marker is a balloon catheter.
