  • Patent number: 8216298
    Abstract: A primary and branch graft deployment delivery system (70) comprises a primary graft (72) having a branch port opening or member (75), a retractable primary sheath containing the primary graft, an outer tube (60) within the retractable primary sheath and within the primary graft, an inner tube (61) within the outer tube, a cap (54 or 71) coupled to the inner tube and configured to retain at least a portion of a proximal area (73) of the primary graft in a radially compressed configuration. The system further comprises a branch graft (89) advanceable through the branch graft port member and further comprising a snap connector member (90) associated with the branch graft, the snap connector member being configured to frictionally engage the port member, the engagement of the snap connector to the port member forms a connection between the proximal end of the branch graft and the primary graft.
    Type: Grant

  • Publication number: 20060149312
    Abstract: In accordance with the present invention, a distal protection and embolic material retrieval device with improved apposition to both large and small vessel walls of varying geometries for enhancing the filtering of embolic material during intravascular procedures while allowing for the passage of blood is provided. The device includes a filter basket designed to maximize apposition of the filtering portion to that of the vessel wall and may include struts which provide circumferential support to the filtering membrane and thereby minimizing or eliminating in-folding of the filter basket. Thin film materials may also be utilized for the filtering membrane of the filter basket. In addition one can incorporate biological and/or pharmaceutical agents in combination with the present invention.
