Abstract:
1. A device for percutaneously winding and unwinding a spiral support wire inside a graft tube to increase and decrease size of said graft tube until equal to size of a pre-selected segment of artery and placing circular sutures through ends of said graft tube and said segment of artery to securely join them, comprising: a. said spiral support wire made of biocompatible material in the shape of a spiral binding with a spiral lumen as found on a spiral notebook with original length and diameter pre-selected to be about equal to that of said pre-selected segment of artery and able to be increased and decreased in length and diameter by winding and unwinding while in said segment of artery, b. said graft tube made of elastic biocompatible material in the shape of a tube with wall thickness less than 1 mm, length and circumference being about equal to that of said pre-selected segment of artery and containing said spiral support wire, c. a distal holding balloon mounted on a distal holding catheter and a proximal holding balloon mounted on a proximal holding catheter, with each of said distal and said proximal holding balloons made of a combination of compliant and non-compliant material, d. a holder rim being in the shape of a flat circular rim of compliant material mounted on a circumference of each said distal holding balloon and said proximal holding balloon and said holder rims being of a width greater than a width of said circumference of said holding balloons thus forming respective overhangs about said circumferences of said distal holding balloon in the proximal direction and said proximal holding balloon in the distal direction, e. a grip opening through a side edge of each of said holder rims being slidably larger than ends of said spiral support wire which are held in said grip openings by inflation pressure, f. a plurality of arc openings each made in the shape and size of one end of a plurality of tunnel arcs and each runs at an acute angle through said overhang in each said holder rim at equally spaced intervals of about 2 mm, g. a plurality of circular sutures of wire diameter about 0.2 mm, made of shape memory material in the shape of a circle of about 2 mm diameter and having one sharp end and one blunt end, h. a plurality of push-rods of same diameter wire as said plurality of circular sutures but being of a straight shape and made of material that is resistant to deformation, and being located contiguously with said plurality of circular sutures, l. a plurality of tunnel arcs, each being a tube of strong, smooth flexible material with a distal end, a proximal end and a length of lumen therebetween and each said tunnel arc being in the shape of an arc of a large oval with length of each said tunnel arc being at least twice as long as a circumference of one of said plurality of circular sutures, and having said lumen of diameter slidably larger than said wire diameter of one of said plurality of circular sutures and having an outside diameter slidably smaller than said arc opening in said holder rim in which each said distal end of each of said plurality of tunnel arcs is inserted and connected and each said tunnel arc extends either from each said arc opening on said rim of said distal holding balloon to attach to a distal push-rod tube or from said arc openings on said rim of said-proximal holding balloon to a proximal push-rod tube, j. said proximal push-rod tube and said distal push-rod tube are catheters that flare from a smaller diameter to a larger diameter and the smaller diameter section of said distal push-rod tube is slidably received within the smaller diameter section of said proximal push-rod tube and each said larger diameter section has a thin wall segment and a thick wall segment with lengths being approximately equal to said circumference of said circular sutures and said thick wall segment having wall thickness to slidably receive said tunnel arcs which are attached to said thick wall segment and each said thick wall segment having a plurality of push-rod tunnels within said wall thickness that are in line with and slidably larger than said push-rods that pass through said push-rod tunnels and said thin wall segment having wall thickness such that a push-rod base will pass through without touching said thin wall section except on a circumference of said push-rod base, k. two said push-rod bases each being a flat disc of inflexible material to which ends of said plurality of push-rods are attached on one side, and a plunger is attached on the other side and said two push-rod bases being made in two diameters one slidably smaller than inside diameter of said thin wall segment of said distal push-rod tube and the other of said thin wall segment of said proximal push-rod tube, l. two said plungers one attached to each said push-rod bases and being catheters, one sized to be slidably received within the other, whereby said device is configured to interact with body parts during use wherein, said spiral support wire located inside folded said graft tube is tightly wound and advanced on a pre-existing guidewire to a segment of artery previously cleared of an occlusion and is allowed to unwind there while operator controls unwinding by controlling rotation of concentric said proximal and said distal holding catheters to which said distal holding balloon and said proximal holding balloon are attached and on each said balloon circumference is said holder rim having said grip opening in which one end of said spiral support wire is held as said distal holding balloon and said proximal holding balloon are partially inflated and then fully inflated as said spiral support wire is unwound causing it to become the size of its original manufacture which was pre-selected to be the same length and circumference as said segment of artery which is to be treated, whereupon operator makes final adjustments to increase and decrease said spiral support wire circumference by twisting said proximal and said distal holder catheters and also simultaneously causing the full inflation of said distal and said proximal holding balloons which also brings said holder rim on said circumference of said holding balloons tightly against said graft tube and an artery wall where said sharp ends of said plurality of circular sutures located in said plurality of tunnel arcs equally spaced around said holder rim are also brought against said graft tube and said artery wall because each said tunnel arc is attached in one of said arc openings in said holder rims whereupon operator pushes said plunger located in said distal push-rod tube while holding said distal push-rod tube which pushes said distal push-rod base in the distal direction which pushes said push-rods in said push-rod tunnels located in said thick wall segment of said distal push-rod tube to which said tunnel arcs are attached and said push-rods push said circular sutures out of said tunnel arcs and into said graft tube and through said artery wall and as circular sutures are released from said tunnel arcs they return to their original circular shapes by the shape memory of the material of which they are made thus connecting said graft tube and said artery wall securely by said plurality of circular sutures, and the same procedure is then followed for said circular sutures in said proximal push-rod tube and said device is then removed from the body leaving said graft tube sutured on both ends to said artery wall throughout said segment of artery previously occluded.
