Abstract
Abstract A device for use in the preparation of a vein for arterial grafting. A tubular core, closed at one end and open at the other end to couple with a source of pressurized fluid, rests removably adjacent each end on a frame. The core wall is perforated in an area intermediate the ends of the core and the outer surface of the core wall is smooth.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
112 words
A device for use in the preparation of a severed length of vein for arterial grafting, comprising: an elongated core having a tubular wall closed at one end to define a chamber and open at the other end to define an inlet to the chamber, the wall being perforated in an area intermediate the ends thereof, the outer surface of the wall being smooth, the core being receivable proximally in the vein intraluminally whereby the vein extends along the core in each direction beyond the perforated area of the wall; and frame means constructed and arranged to receive the core removably and to hold the core adjacent the ends of the wall.
Claim 2
Independent Claim
112 words
A device for use in the preparation of a severed length of vein for arterial grafting, comprising: an elongated core having a tubular wall closed at one end to define a chamber and open at the other end to define an inlet to the chamber, the wall being perforated in an area intermediate the ends thereof, the outer surface of the wall being smooth, the core being receivable proximally in the vein intraluminally whereby the vein extends along the core in each direction beyond the perforated area of the wall; and frame means constructed and arranged to receive the core removably and to hold the core adjacent the ends of the wall.
Claim 3
Dependent Claim
29 words
A device as claimed in claim 1 in which the frame means comprises a base and two spaced, upstanding brackets shaped to receive the core transversely to rest thereon.
Claim 4
Dependent Claim
54 words
A device as claimed in claim 2 in which one bracket has an aperture adjacent the upper end thereof to receive axially the closed end of the wall of the core and the other bracket is notched at the upper end thereof to receive transversely the wall of the core adjacent said other end.
Claim 5
Dependent Claim
26 words
A device as claimed in claim 2 in which the base comprises a flat plate and the core rests on the brackets parallel to the plate.
Claim 6
Dependent Claim
30 words
A device as claimed in claim 1 in which the wall carries a connector at the open end thereof, the connector having means to couple to pressurized fluid source thereto.
Claim 7
Dependent Claim
48 words
A device as claimed in claim 5 in which the connector is tubular coaxial with the wall of the core, the connector carrying a pair of spaced circumferential rings, at least one bracket being notched at the upper end thereof to receive the connector therein between the rings.
Claim 8
Dependent Claim
13 words
A device as claimed in claim 1 in which the core is plIable.
