  • Patent number: 6827730
    Abstract: A reduced diameter stent/graft deployment catheter and a method of insertion for said catheter. The delivery sheath portion of the catheter, i.e. the distal portion of the catheter containing the stent/graft, has a larger outer diameter than the remaining proximal portion of the catheter. The reduced outer diameter of the body of the catheter allows for the use of a smaller diameter introducer sheath. The method of inserting said catheter comprises the following steps: First, the delivery sheath portion of the catheter is inserted into the patient. Next, an introducer sheath, with an outer diameter which is no larger than the outer diameter of the delivery sheath, is disposed about the catheter and its distal portion inserted into the patient. The catheter is then advanced into the patient and the stent/graft deployed.

  • Patent number: 6776791
    Abstract: A method for inserting a stent into the delivery sheath of a stent/graft deployment catheter. The stent has V hooks on its proximal end which are positively engageable by projections attached to a stent/graft deployment catheter plunger. The proximal end of the stent is manually squeezed over the V hooks such that the V hooks engage the projections. The catheter is passed through the center of a funnel. While maintaining pressure on the stent and the V hooks, the plunger is withdrawn so as to pull the stent into the delivery sheath through the center of the funnel. The funnel guides the stent into the delivery sheath and gradually compresses the stent as it approaches the delivery sheath.

  • Patent number: 6767361
    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: 6729356
    Abstract: A graft provided with a flexible sealing member to substantially prevent blood from leaking between the graft a lumen into which the graft is placed. In one embodiment, the flexible sealing member may be pressed against the vascular wall by an outwardly biased spring means attached to the sealing member. In other embodiments, the sealing member may be self-positioning upon deployment of the graft. The sealing member also may be formed into the shape of a toroid, which may be filled with thrombogenic material causing blood permeating into the toroid-shaped space to coagulate therein and hold the sealing member in place. It is also contemplated that the sealing member be formed from tufts of frayed yarn protruding circumferentially from the outer surface of the graft. A method of manufacturing such tufted yarn sealing members is also disclosed.
