Abstract: A method and apparatus 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.

Abstract: In one embodiment, a delivery system for a medical device includes a flexible sheath defining a lumen having a distal end and a flexible shaft having a proximal portion and a distal portion. A retention element and a pushing element, spaced proximally from the retention element, are disposed on the distal portion. The flexible shaft, retention element, and pushing element are disposable within the lumen. The flexible shaft is movable distally through the lumen between a stowed position and a deployed position and is movable proximally through the lumen between the deployed position and a partially deployed position with the retention element proximate to the distal end of the lumen. The retention element is configured to form with the medical device an interference fit with the flexible sheath when the flexible shaft is urged proximally from the retention position to engage the medical device with the flexible sheath.

Abstract: A method and apparatus 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.

Abstract: A braided device comprising: filaments of a first type and of a second type, the second type differing from the first type in at least one characteristic; the first type of filaments defining an integral symmetrical 1×1 sub-pattern; and the combination of the first type of filaments and the second type of filaments being braided together into a braided device exhibiting a uniform braid pattern.

Abstract: A method of and an apparatus for making a braided intraluminal implant, by providing a mandrel having at least one small-diameter section joined at least at one end to a large-diameter section; interweaving a plurality of filaments to form a tubular braid enclosing at least a part of the small-diameter section and at least a part of the large-diameter section; and cutting the tubular braid to produce a tubular braid segment having outwardly flared ends at its opposite ends. One flared end is produced by the large-diameter section of the mandrel, and the opposite outwardly flared end may be produced either by another large-diameter section of the mandrel, or by cutting the tubular braid at a portion formed by the small-diameter section of the mandrel but at a location wherein the release of stresses in the filaments inherently produces an outward flaring of the braid at that end.

Abstract: A striped braided element comprising: a first set of members having a common direction of winding, the center axis of said first set of members being axially displaced relative to each other in relation to a common braiding axis; and a second set of members having an opposite direction of winding, the center axis of the second set of members being axially displaced relative to each other in relation to the common braiding axis, the braided element exhibiting a uniform uninterrupted braid pattern and an average uniform distance between the center axis of members having a common direction of winding at a particular circumferential section along the common braiding axis; characterized by having at least one stripe comprising two adjacent members of the same set exhibiting a significantly reduced distance between the center axis of the adjacent members in the particular circumferential section.
