Abstract
Abstract A vein holder assembly for use in the preparation of a vein segment during surgery comprises a base and a first vein support connected to the base and adapted to close off one end of the vein segment. A second vein support is connected to the base spaced from the first vein support. This second vein support is adapted to allow fluid to pass into the vein segment while the same is being supported. To accommodate different length vein segments, the spacing between the first and second vein supports is adjustable.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
165 words
A vein holder assembly for use in the preparation of a vein segment during surgery comprising: an elongate base having a groove in its elongate direction; first slide means connected to said base and adapted to slide in said groove; first adjustable tightening means associated with said first slide means for tightening the same in a selected position on said base; a vein clamp mounted on said first slide means for closing off one end of a vein segment; second slide means connected to said base and adapted to slide in said groove; second adjustable tightening means associated with said second sliding means for tightening the same in a selected position on said base; a vein support mounted on said second slide means adapted to allow fluid to pass into said vein segment while supporting the same and while the other end of said vein segment is closed off by said vein clamp whereby said vein segment may be maintained in a fluid distended condition.
