Abstract
Abstract A holding device (10) for use during surgical procedures involving tubular body ducts (24) includes a shank portion (14) and a terminal portion (16). The terminal portion (16) has a bulbous section (20) at the terminus of the rod (12). The outer surface of the terminal portion (16) is free of discontinuities, and the bulbous section (20) has a cross-sectional dimension slightly less than the diameter of the tubular body duct (24). The terminal portion (16) can be received within the body duct (24) so that the bulbous section (20) will resist withdrawal when the body duct (24) is tied to the terminal portion (16). <IMAGE>

Claims Analysis
Total Claims: 24
Claim 1
Independent Claim
104 words
A holding device for holding a vein during vascular surgery, said device comprising a substantially rigid elongated rod having a shank portion, and a terminal portion connected to the shank portion, said terminal portion having a bulbous section spaced from the shank portion, the outer surface of the terminal portion being free of discontinuities, and the bulbous section having a cross-sectional dimension slightly less than the diameter of the vein so that the terminal portion can be received within the vein and the bulbous section resist withdrawal therefrom when the diameter of the vein between the bulbous section and the shank portion is reduced.
Claim 2
Dependent Claim
104 words
A holding device for holding a vein during vascular surgery, said device comprising a substantially rigid elongated rod having a shank portion, and a terminal portion connected to the shank portion, said terminal portion having a bulbous section spaced from the shank portion, the outer surface of the terminal portion being free of discontinuities, and the bulbous section having a cross-sectional dimension slightly less than the diameter of the vein so that the terminal portion can be received within the vein and the bulbous section resist withdrawal therefrom when the diameter of the vein between the bulbous section and the shank portion is reduced.

Claim 13
Dependent Claim
58 words
A holding assembly for holding a vein during vascular surgery comprising a substantially rigid elongated rod having a shank portion and an integral terminal portion; engagement means for causing the terminal portion to functionally engage and retain the interior wall of the vein against movement thereof relative to the rod without placing point stresses on the interior wall.
Claim 14
Dependent Claim
58 words
A holding assembly for holding a vein during vascular surgery comprising a substantially rigid elongated rod having a shank portion and an integral terminal portion; engagement means for causing the terminal portion to functionally engage and retain the interior wall of the vein against movement thereof relative to the rod without placing point stresses on the interior wall.
Claim 15
Dependent Claim
20 words
A holding device according to claim 12 wherein the engagement means comprises a bulb integrally connected to the terminal portion.
Claim 16
Dependent Claim
24 words
A holding device according to claim 13 wherein the outer surface of the bulb in combination with the terminal portion is free of discontinuities.
Claim 17
Dependent Claim
26 words
A holding device according to claim 13 wherein the engagement means further comprises a tie adapted to be disposed around the outer wall of the vein.
Claim 18
Dependent Claim
17 words

Claim 19
Dependent Claim
119 words
A holding assembly for holding a vein during vascular surgery comprising: a substantially rigid elongate rod having a shank portion and a terminal portion, said terminal portion having a bulbous section spaced from the shank portion, the outer surface of the terminal portion being free of discontinuities, and the bulbous section having a transverse cross-sectional dimension slightly less than the diameter of the vein; and means for reducing the diameter of the vein whereby the bulbous section can be received within the vein and resist withdrawal therefrom when the diameter of the vein between the bulbous section and the shank portion is reduced by the reducing means and the vein can thereby be held by grasping the shank portion.
Claim 20
Dependent Claim
119 words
A holding assembly for holding a vein during vascular surgery comprising: a substantially rigid elongate rod having a shank portion and a terminal portion, said terminal portion having a bulbous section spaced from the shank portion, the outer surface of the terminal portion being free of discontinuities, and the bulbous section having a transverse cross-sectional dimension slightly less than the diameter of the vein; and means for reducing the diameter of the vein whereby the bulbous section can be received within the vein and resist withdrawal therefrom when the diameter of the vein between the bulbous section and the shank portion is reduced by the reducing means and the vein can thereby be held by grasping the shank portion.
Claim 21
Dependent Claim
25 words
