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 mabrane 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.

Claims

1. A system for intraluminally repairing a diseased portion of a first corporeal lumen within a patient'"'"'s vasculature which includes a second corporeal lumen branching from the first corporeal lumen, comprising:

a repair device configured to be placed intraluminally within the patient'"'"'s vasculature, said repair device adapted for tissue ingrowth, and

a catheter sized for placement within the second corporeal lumen and for being advanced within the patient'"'"'s vasculature to the first corporeal lumen, said catheter being flexible and having an outer profile that facilitates advancement from the second corporeal lumen to the first corporeal lumen and further having a radially expandable inflatable portion and being operatively associated with said repair device for intraluminally deploying said repair device within the first corporeal lumen, said radially expandable inflatable portion configured to engage said repair device to implant said repair device within the first corporeal lumen so that the diseased portion of the corporeal lumen is thereby repaired.

2. The apparatus of claim 1, further comprising a fastening element in operative relationship with said repair device and said catheter for fastening said repair device within the first corporeal lumen.

3. The apparatus of claim 2, wherein said repair device is a hollow member capable of being fastened in an aorta in order to intraluminally repair the aorta.

4. The apparatus of claim 1, wherein said repair device comprises a hollow tubular member having a proximal portion and having means proximate to said proximal portion for fastening said repair device within the first corporeal lumen.

5. The apparatus of claim 4, wherein said fastening element comprises an intraluminal anchoring device connected to said proximal portion, said anchoring device having a plurality of wall engaging members configured to engage the corporeal lumen in which said repair device is in place to fasten said repair device therein.

6. The apparatus of claim 5, further comprising an inflation device, wherein said inflatable portion can be inflated by said inflation device to cause said wall engaging members to engage the first corporeal lumen, and can be deflated by said inflation device to disassociate said catheter from the fastened device.

7. The apparatus of claim 1, wherein said repair device has a collapsed condition for intraluminal delivery and an expanded condition for use in repairing the first corporeal lumen.

8. The apparatus of claim 1, wherein said catheter is capable of implacing said repair device at a desired position in a damaged or diseased fluid conducting corporeal lumen to repair or reinforce same.

9. The apparatus of claim 1, wherein said repair device has a high tissue ingrowth rate, said repair device being deformable both axially and radially and capable of substantially conforming to the interior shape of the corporeal lumen into which said repair device is implaced.

10. The apparatus of claim 1, wherein said inflatable portion of said catheter is selectively inflatable to engage said repair device and is selectively deflatable to disassociate said catheter from said repair device.
