  • Patent number: 6030413
    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.

  • Patent number: 5957973
    Abstract: An intraluminal grafting system having a balloon catheter assembly, a capsule catheter assembly and capsule jacket assembly is used for deploying a graft having attachment means in the vessel of an animal body. The system contains a proximal capsule means and a distal capsule means, wherein the graft is disposed within the two capsule means and a removable sheath covers the graft and capsule means. The graft is comprised of a tubular member having superior and inferior ends, having attachment means with wall engaging members secured thereto. The balloon catheter is disposed within the capsule catheter to provide relative movement between the balloon catheter and the capsule catheter, whereby the graft can be removed from the capsule means. The balloon is inflated to firmly implant the graft and attachment means within the vessel. The graft and attachment means remain in the vessel after the intraluminal grafting system is withdrawn.

  • Patent number: 5935122
    Abstract: A sheath assembly for use in introducing a catheter or other medical instrument into a vessel in the body of a patient. The sheath assembly includes an outer tubular member and an inner tubular member with a conically shaped cap at its distal end. A locking mechanism prevents advancement of the inner tubular member and associated cap in a distal direction of the vessel of the patient independent of the outer tubular member, but allows free movement of the inner tubular member in the proximal direction independent of the outer tubular member.

    Abstract: Endovascular grafting system having a capsule catheter comprising a flexible elongate tubular member having proximal and distal extremities and a capsule mounted on the distal extremity of the tubular member. The capsule is generally cylindrical in shape and is formed of a helical wrap of a metal ribbon. The wraps are bonded into a unitary capsule permitting bending of said unitary capsule. A graft is disposed within the capsule. The graft is comprised of a tubular member having proximal and distal ends. Hooks are secured to the proximal and distal ends of the tubular member and face in a direction outwardly towards the inner wall of the capsule. A push rod is disposed within the capsule catheter and engages the graft whereby upon relative movement between the push rod and the capsule catheter, the graft can be forced out of the capsule.
