Artificial graft and implantation method
First Claim
1. A system for engrafting in a fluid conducting corporeal lumen comprising:
- a hollow graft of preselected cross-section and length having a proximal end and a distal end for placement within said corporeal lumen, said hollow graft being deformable to substantially conform to the interior surface of said corporeal lumen;
a proximal staple positioned proximate the proximal end of said graft, said proximal staple being formed and positioned to urge said hollow graft against said interior surface and having lumen engaging members positioned and adapted for holding said proximal end of said hollow graft to and within said corporeal lumen;
a distal staple positioned proximate the distal end of said hollow graft, said distal staple being formed and positioned to urge said hollow graft against said interior surface and having lumen engaging members positioned and adapted for holding said distal end of said hollow graft to and within said corporeal lumen; and
placement means for introducing and carrying said hollow graft with said proximal staple and said distal staple into and within said corporeal lumen and for placing and engrafting said hollow graft with said proximal and distal staples at a preselected position within and to said corporeal lumen by advancing the hollow graft to the preselected position, said placement means including a cylindrical capsule sized and shaped for positioning in and movement through said corporeal lumen and formed to have an interior sized and shaped to receive said hollow graft with said proximal and distal staples, said cylindrical capsule having proximal and distal extremities, said distal extremity having an aperture formed therein for passage therethrough of said hollow graft with said proximal and distal staples.

Abstract
An intraluminal grafting system includes a hollow graft which has a proximal staple positioned proximate its proximal end and a distal staple adapted proximate its distal end. The system includes a capsule for transporting the graft through the lumen and for positioning the proximal end of the graft upstream in a lumen which may be a blood vessel or artery. A tube is connected to the capsule and extends to exterior the vessel for manipulation by the user. A catheter is positioned within the tube to extend from the cavity and through the graft to exterior the body. The catheter has an inflatable membrane or balloon proximate the distal end thereof which is in communication via a channel with inflation and deflation means located exterior the vessel. With the inflatable membrane deflated, the capsule is positioned in the lumen and manipulated to a desired location. The inflatable membrane is manipulated by the rod away from the graft. The force exerted by the inflatable membrane and the structure of the staples urges the staples in the vessel wall, retaining the graft in position. The remainder of the intraluminal grafting system is then removed from the corporeal vessel.

9. A system for engrafting in a fluid conducting corporeal lumen comprising:
-
a deformable hollow graft of preselected cross-section and length having a proximal end and a distal end for placement within said corporeal lumen, said hollow graft being deformable axially and radially to substantially conform to the interior surface of said corporeal lumen; proximal staple means positioned proximate the proximal end of said graft, said proximal staple means being formed of a spring-like material to urge said hollow graft against said interior surface of the corporeal lumen and having at least one lumen piercing member adapted to engage said corporeal lumen;
said proximal staple means being movable between a first condition in which it is compressed about a central axis and a second condition in which it is decompressed and springs outwardly from said central axis anddistal staple means positioned proximate the distal end of said hollow graft, said distal staple means being formed of a spring-like material to urge said hollow graft against said interior surface of the corporeal lumen and having a lumen member adapted to engage said corporeal lumen; and placement means carrying said hollow graft with its proximal and distal staple adapted thereto for placing and engrafting said hollow graft at a preselected positioned within said to said corporeal lumen.

10. For engrafting a corporeal lumen, a system comprising;
-
a hollow graft for placement within said corporeal lumen having a preselected length and a cross-section proximate the cross-section of said corporeal lumen, said hollow graft having a proximal end and a distal end and being deformable to substantially conform to the interior surface of said corporeal lumen; proximal staple means made of a spring-like material movable between a first condition in which it is compressed about a central axis and a second condition in which it is decompressed and springs outwardly from said central axis, said proximal staple means having a plurality of lumen piercing members and being positioned proximate said proximal end of said hollow graft to urge the said hollow graft against the interior surface of said corporeal lumen and to urge said lumen piercing members through said hollow graft and into said corporeal lumen; distal staple means made of a spring-like material movable between a first condition in which it is collapsed about a central axis and a second condition in which it is decompressed and spring outwardly from said central axis, said distal staple means having a plurality of lumen piercing members and being positioned proximate the distal end of said hollow graft to urge the said hollow graft against the interior surface of said corporeal lumen and to urge said lumen piercing member through said hollow graft and into said corporeal lumen; a capsule sized to receive said hollow graft and said proximal staple and said distal staple each in its first condition and positioned within said hollow graft, said capsule having a proximal extremity with an opening therein, said capsule being sized for transport through said corporeal lumen; and means mechanically coupled to said capsule for positioning said capsule within said corporeal lumen and for causing relative movement between the capsule and the hollow graft whereby said hollow graft with said proximal and distal staples adapted thereto are urged out of said capsule for releasing said distal and proximal staple means for movement to their respectively second conditions.
