  • Publication number: 20050010281
    Abstract: A method for reducing blood flow to an aneurysm proximate to a bifurcation having a source blood vessel a first branch vessel and a second branch vessel, the method comprising: providing a first mesh-like tube of bio-compatible material, the first mesh-like tube exhibiting a porosity index pre-selected to skew blood flow about the bifurcation away from the aneurysm; inserting the first mesh-like tube into the source blood vessel and the first branch vessel; and securing the first mesh-like tube to at least one of the source blood vessel and the first branch vessel, whereby blood flowing from the source blood vessel flows without undue impedance to the first branch vessel and the second branch vessel while being skewed away from the aneurysm.

  • Publication number: 20040122468
    Abstract: A diverting filter for implantation in the bifurcation of the human common carotid artery (CCA) with the external carotid artery (ECA) and the internal carotid artery (ICA), comprising: a tubular body expandable from an initial small-diameter state for manipulation through the CCA to an expanded larger-diameter state for implantation in said bifurcation, the tubular body having an at rest state wherein the tubular body exhibits a diameter greater than the expanded larger-diameter state; the tubular body including a proximal region for implantation in the CCA, a distal region for implantation in the ECA, and a middle filtering region for alignment with the orifice of the ICA for diverting relatively-large emboli in the CCA blood flow to the ECA while minimizing interference to blood flow through both the ICA and the ECA; constituted of between 48 and 56 braided filaments exhibiting an average porosity index of at least 80%.

  • Publication number: 20040049204
    Abstract: A system for delivering and for deploying an expandable intraluminal device at a selected location in a body lumen wall, includes: an inner supporting structure for supporting the intraluminal device; an outer tube for enclosing the inner supporting structure, and the intraluminal device when supported in its contracted condition thereon; and a pair of socks for receiving between them the ends of the intraluminal device in its contracted condition. Each sock has one end secured to the inner supporting structure, an opposite end facing the other sock for receiving the respective end of the intraluminal device in its contracted condition, and a length such that, when the outer tube is removed and the intraluminal device starts to expand, each sock does not release the respective end of the intraluminal device until the center region of the intraluminal device expands into engagement with the body lumen wall.

  • Publication number: 20040024416
    Abstract: An implantable deflecting device for positioning in the vicinity of an arterial bifurcation for causing embolic material flowing toward a first branch of the bifurcation to be deflected into the second branch of the same bifurcation. The device comprises a deflecting filtering element suitable to deflect the flow of embolic material flowing toward said second branch, while filtering the blood flowing toward said first branch. The device comprising a braided tubular body having a contracted state with a first diameter, and an expanded state having a second diameter greater than said first diameter.

  • Publication number: 20040010308
    Abstract: An implantable device particularly useful for implantation in the common carotid artery at its bifurcation with the internal carotid artery and the external carotid artery for reducing the risk of a stroke, includes a base element for anchoring the device in the artery, and a deflector element for covering the inlet of the internal carotid artery. The deflector element is formed with openings of a size and configuration to deflect emboli in the blood to the external carotid artery without blocking blood flow through the external or internal carotid arteries. The deflector element is attached to a supporting portion of the base element to produce a composite construction. In one described embodiment, the base element is a coil having two opposing ends which overlap to permit expansion for deployment in the artery, and in a second described embodiment the base element is a tube expandable for deployment in the artery.

  • Publication number: 20040010307
    Abstract: A device implantable in an artery at a bifurcation into a first branch supplying blood to a vital region having a high sensitivity to emboli in the blood, and a second branch supplying blood to a less vital region having a lower sensitivity to emboli in the blood. The implantable device is initially of a small diameter for facilitating its introduction into and deployment through the artery to the bifurcation, and is expandable to a larger diameter for implantation in the artery at the bifurcation. The implantable device includes a base element for anchoring in the artery at the bifurcation; and a deflector element for covering the inlet of the first branch at the bifurcation. The deflector element is formed with openings of a size and configuration to deflect emboli in the blood to the second branch without blocking blood flow through the second branch or through the first branch.

  • Publication number: 20030100945
    Abstract: An intraluminal device implantable in a blood vessel having an aneurysm therein in the vicinity of a perforating vessel and/or of a bifurcation leading to a branch vessel. The intraluminal device includes a mesh-like tube of bio-compatible material having an expanded condition in which the tube diameter is slightly larger than the diameter of the blood vessel in which it is to be implanted, and the tube length is sufficient to straddle the aneurysm and to be anchored to the blood vessel on the opposite sides of the aneurysm. The mesh-like tube also has a contracted condition wherein it is sufficiently flexible so as to be easily manipulatable through the blood vessel to straddle the aneurysm.
