Abstract
Abstract An apparatus for vessel transfer comprising a tubular outer member and an inner slidable member one of which is rigid and the other of which is flexible. After the apparatus has been inserted in the body tissue, the rigid member is withdrawn from the body leaving the flexible member in place. A vein, prosthesis or elastomeric tubing attaching structure is secured to the end of the flexible member so that the flexible member can be used to pull said vein, prosthesis or elastomeric tubing through the body tissues to an elected distant site where the tip of the flexible member has been surgically exposed.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
202 words
An apparatus for vessel transfer comprising a tubular outer member and an inner slidable member, one of which is rigid and one of which is flexible, said tubular outer member and inner slidable member being adapted to be passed through body tissue to an elected distant site which has been surgically exposed, a handle means extending aside and fixed to one end of said outer member, said handle means being adapted to insert said tubular outer member containing said inner slidable member into body tissue and to pull said tubular outer member from body tissue leaving said inner slidable member in body tissue, and attaching means adapted to attach a hollow vein, prosthesis or elastomeric tubing to one end of the flexible member after removing the outer member from the body tissue so that the flexible member can be used to pull said hollow vein, prosthesis or elastomeric tubing through the body tissue to said elected distant site, said attaching means comprising a body adapted to be inserted into said hollow vein, prosthesis or elastomeric tubing, said body having a diameter of at least a portion of its surface greater than the interior diameter of said hollow vein, prosthesis or elastomeric tubing.
Claim 2
Independent Claim
202 words
An apparatus for vessel transfer comprising a tubular outer member and an inner slidable member, one of which is rigid and one of which is flexible, said tubular outer member and inner slidable member being adapted to be passed through body tissue to an elected distant site which has been surgically exposed, a handle means extending aside and fixed to one end of said outer member, said handle means being adapted to insert said tubular outer member containing said inner slidable member into body tissue and to pull said tubular outer member from body tissue leaving said inner slidable member in body tissue, and attaching means adapted to attach a hollow vein, prosthesis or elastomeric tubing to one end of the flexible member after removing the outer member from the body tissue so that the flexible member can be used to pull said hollow vein, prosthesis or elastomeric tubing through the body tissue to said elected distant site, said attaching means comprising a body adapted to be inserted into said hollow vein, prosthesis or elastomeric tubing, said body having a diameter of at least a portion of its surface greater than the interior diameter of said hollow vein, prosthesis or elastomeric tubing.
Claim 3
Dependent Claim
53 words
Apparatus as claimed in claim 1 further comprising insertion means, wherein said outer member is in the form of a rigid tube, and said inner member is a flexible member having first and second ends with said insertion means secured on said first end, and said attaching means secured on said second end.
Claim 4
Dependent Claim
14 words
Apparatus as claimed in claim 2 wherein said attaching means is frusto-conical in shape.
Claim 5
Dependent Claim
34 words
Apparatus as claimed in claim 2 wherein said insertion means is a member having a diameter of at least a portion of its surface greater than the interior diameter of said tubular outer member.
Claim 6
Dependent Claim
12 words
Apparatus as claimed in claim 4 wherein said insertion means is arrow-shaped.
Claim 7
Dependent Claim
12 words
Apparatus as claimed in claim 4 wherein said insertion means is bullet-shaped.
Claim 8
Dependent Claim
135 words
A vessel transfer apparatus for transferring a hollow flexible conduit such as a blood vessel, prosthesis, elastomeric tubing or the like through body tissues comprising a rigid hollow tube member, handle means fixed to one end of said rigid hollow tube member, a flexible rod-like member moveably mounted within said rigid hollow tube member, said handle means being adapted to push said rigid hollow tube member and said rod-like member through body tissues and remove said rigid hollow tube member from body tissues, said flexible rod-like member comprising a rod-like body with attachment means on one end and a probe head on the other end, said attachment means defining an end surface adapted to be inserted in said hollow flexible conduit and shoulders adapted to engage and hold the interior of said hollow flexible conduit.
Claim 9
Dependent Claim
135 words
A vessel transfer apparatus for transferring a hollow flexible conduit such as a blood vessel, prosthesis, elastomeric tubing or the like through body tissues comprising a rigid hollow tube member, handle means fixed to one end of said rigid hollow tube member, a flexible rod-like member moveably mounted within said rigid hollow tube member, said handle means being adapted to push said rigid hollow tube member and said rod-like member through body tissues and remove said rigid hollow tube member from body tissues, said flexible rod-like member comprising a rod-like body with attachment means on one end and a probe head on the other end, said attachment means defining an end surface adapted to be inserted in said hollow flexible conduit and shoulders adapted to engage and hold the interior of said hollow flexible conduit.
Claim 10
Dependent Claim
28 words
Apparatus as claimed in claim 7 wherein said probe head comprises an arrow-shaped head having its widest portion greater than the diameter of said hollow rigid tubular member.
Claim 11
Dependent Claim
28 words
Apparatus as claimed in claim 7 wherein said probe head comprises a bullet-shaped member having shoulders defined therein which extend past the diameter of said rigid tubular member.
Claim 12
Dependent Claim
14 words
Apparatus as claimed in claim 7 wherein said attachment means comprises a nipple-shaped end.
Claim 13
Independent Claim
223 words
An apparatus for the transfer of a vessel within a human body comprising an assembly in a form of an outer tubular member and an inner slidable rod member positioned within said outer tubular member, one of said members being rigid and the other member being flexible, said rod member including means formed at one end which is of greater size than the interior diameter of said outer tubular member, handle means fixed to one end of said rigid member to push said assembly into body tissues and pull said rigid member from body tissues, said assembly being adapted to pass through body tissues to an elected distant site which has been surgically exposed so that the assembly is exposed, said flexible member being held within the body tissues while the rigid member of the assembly is removed from the body tissues, and attachment means to attach a hollow vein, prosthesis, elastomeric tubing or the like to an end of the flexible member after removal of the rigid member from the body tissues so that the flexible member can be used to lead said vein, prosthesis, elastomeric tubing or the like under tension through the body tissues to said elected distant site, said attachment means being adapted to engage and hold an interior surface of said vein, prosthesis, elastomeric tubing or the like.
