Abstract
In one exemplary embodiment, an intraluminal device may include elongated structure formed of a plurality of wires. The intraluminal device may also include a plurality of sets of looped wires longitudinally located at an intermediate area of the elongated structure and the plurality of sets may be spaced circumferentially about the structure and being configured to cooperate with each other to form a plurality of clot entry openings. At least one grouping of woven wires may be longitudinally located adjacent the intermediate area and the at one grouping of woven wires may be configured such that when an opening force is exerted on the elongated structure, the at least one grouping provides structural support to hold open first interstices between the plurality of sets of looped wires.
Core Innovation
The invention relates to an intraluminal device including an elongated structure formed of a plurality of wires. The device includes a plurality of sets of looped wires located along at least one portion of the elongated structure, where the sets are spaced circumferentially and are configured to cross each other at a plurality of intersection locations. The crossings form a plurality of clot entry openings in the intraluminal structure.
At least two groupings of woven wires are spaced longitudinally from each other on opposite sides of the at least one portion. The groupings cooperate such that when an opening force is exerted on the elongated structure, the woven-wire groupings provide structural support to hold open first interstices between the plurality of sets of looped wires. In response to the opening force, second interstices are formed between wires in each of the at least two groupings of woven wires, and the first interstices in the looped wire sets are larger than the second interstices between wires in each grouping.
In specified embodiments, the structure is formed of 12 wires that define six sets of looped wires, and adjacent to the six sets of looped wires the 12 wires collectively form at least one grouping of woven wires. The looped-wire sets cross to create multiple clot entry openings, while the woven-wire groupings provide localized structural organization in at least one area adjacent to the looped-wire region.
Claims Coverage
The document contains two independent claims. Across the independent claims, the coverage centers on circumferential sets of crossed looped wires forming clot entry openings, together with longitudinal or localized woven-wire groupings that define interstice sizes under an opening force, including a 12-wire and six-set configuration.
Circumferential crossed looped wires forming clot entry openings with woven-wire interstice size control
An intraluminal device with an elongated structure formed of a plurality of wires, having pluralities of sets of looped wires spaced circumferentially and configured to cross at intersection locations to form clot entry openings, and having at least two groupings of woven wires spaced longitudinally on opposite sides that, when an opening force is exerted, provide structural support to hold open first interstices between the looped-wire sets while forming second interstices between wires in each woven-wire grouping, where the first interstices are larger than the second interstices.
Twelve-wire six-set looped configuration with an adjacent woven-wire grouping
An intraluminal device with an elongated structure formed of a plurality of wires, including a plurality of sets of looped wires spaced circumferentially and crossing to form clot entry openings, where the structure is formed of 12 wires defining six sets of looped wires and, in at least one area adjacent to the six sets of looped wires, the 12 wires collectively form at least one grouping of woven wires.
Overall, the independent claim set covers an intraluminal wire structure that uses crossed looped-wire sets to form clot entry openings and employs woven-wire regions to control interstices sizes when subjected to an opening force, with additional independent coverage of a 12-wire architecture defining six looped-wire sets and an adjacent woven-wire grouping.
