Definitions

  • Vessel re-entry port 218 is shown as a part of blood vessel 100 such that clot 102 is removed from circulation, but vessel re-entry port 218 could reside in a separate blood vessel (not specifically shown) as required by the patient's anatomy and the particular pathology involved. Wire needle 216 punctures the vessel to establish re-entry port 218.
  • bypass catheter 210 is removed and bypass stent graft 108 is passed over wire needle 216.
  • Distal end 114 is placed in the vessel at re-entry port 218 and expanded to fit snuggly with the vessel wall in a sealing relationship.
  • Bypass stent graft could be expanded using a balloon or made out of an expanding material, such as, for example, shaped memory alloys.
  • the proximate end 112 and access port 110 are joined in a sealing relationship, as explained below.
  • Reference number 408 could be a sealing ring, such as a GORTEX® washer, that could be deployed between seating surface 404 and engaging surface 406 to further inhibit blood flow.
  • reference number 408 could be a form of epoxy, acrylic, silicone, tape, glue, or resin that seals seating surface 404 and engaging surface 406.
  • bypass stent graft 108 and/or main vessel stent graft 102 could be constructed out of shaped memory alloys, such as, for example, Ag-Cd alloys, Cu-Al-Ni alloys, Cu-Sn alloys, Cu-Zn alloys, Cu-Zn-Si alloys, Cu-Zn-Sn alloys, Cu-Zn- Al alloys, In-Ti alloys, Ni- Al alloys, Ni-Ti alloys, Fe-Pt alloys, Mn-Cu alloys, Fe-Mn-Si alloys, and the like. These could be designed such that seating surface 404 and engaging surface 406 form an adequate seal and then deformed for deployment.
  • shaped memory alloys such as, for example, Ag-Cd alloys, Cu-Al-Ni alloys, Cu-Sn alloys, Cu-Zn alloys, Cu-Zn-Si alloys, Cu-Zn-Sn alloys, Cu-Zn- Al alloys, In-Ti alloys, Ni
  • FIG. 5 shows a cut-away portion of a vessel 500.
  • vessel 500 contains a type of aneurysm 502 or other vascular pathology that needs to be isolated from vessel 500.
  • FIG. 7 shows placing branch locating stent graft 702.
  • Branch locating stent graft 702 would have a radiopaque edge 704 proximate vessel 500.
  • Main vessel stent graft 508 would be passed to the vascular site occluding branch vessels 504.
  • Trocar 604 would then be aligned with radiopaque edge 704 and main vessel stent graft 508 would be punctured to form access port 512.
  • a connecting stent 706 would then be placed such that a distal end 708 of connecting stent 706 resided in and formed a sealing relationship with branch locating stent 702 and a proximate end 710 of connecting stent 706 resides in and forms a sealing relationship with access port 712.

Abstract

L'invention concerne une endoprothèse vasculaire. Cette endoprothèse vasculaire comprend une endoprothèse vasculaire principale et une endoprothèse de dérivation qui permet de dévier une partie de l'anatomie vasculaire, de connecter une endoprothèse secondaire afin de dévier l'écoulement sanguin dans les vaisseaux secondaires et de retrancher une partie de l'anatomie vasculaire. L'endoprothèse vasculaire principale est pourvue d'un orifice d'accès ou perforée de façon à présenter un orifice d'accès à travers lequel passe l'endoprothèse de dérivation ou la branche de connexion. On obtient ainsi une relation d'étanchéité entre les stents afin d'empêcher les fuites ou les saignements.
