  • System and Methods for Treating a Bifurcation
    Publication number: 20240082030
    Abstract: A system for treating a bifurcation includes first and second delivery catheters, each having an expandable member and a stent. The stent on the second delivery catheter has a side hole. A portion of the first delivery catheter is disposed under a portion of the stent on second delivery catheter. The first delivery catheter is slidable relative to the second delivery catheter, and the first delivery catheter passes through the side hole.
    Type: Application
    Filed: November 21, 2023
    Publication date: March 14, 2024
    Inventors: Henry Bourang, Mehran Khorsandi
  • PARTIALLY CRIMPED STENT
    Publication number: 20240082029
    Abstract: A crimping method that crimps a stent over multiple catheters. The method includes differentially crimping a stent on certain portions of a balloon catheter so that a second catheter can be threaded through the uncrimped portion of the stent and exit through the links of a conventional stent design or through a specific hole in the stent designed for a branched vessel.

  • SELECTIVE STENT CRIMPING
    Publication number: 20220346990
    Abstract: Methods for crimping a stent on an expandable member of a delivery catheter, and devices and methods for treating a bifurcation are disclosed. A method for crimping includes positioning a stent having a first portion and a second portion over the expandable member, and non-uniformly crimping the stent to the expandable member. The method can include routing an elongate shaft under the second portion of the stent and through the side hole so as to be routed external to the first portion. The stent second portion can be crimped so that the elongate shaft can be slidably disposed relative to the stent second portion prior to deployment of the stent.

  • STENT ALIGNMENT DURING TREATMENT OF A BIFURCATION
    Publication number: 20220265451
    Abstract: A system for treating a bifurcation includes a first radially expandable stent and a second radially expandable stent. The first stent has a side hole and a plurality of lateral elements extending from the side hole. The second stent has a plurality of axial elements extending away from the proximal end of the second stent. The axial elements of the second stent interdigitate with the lateral elements of the first stent when both stents have been expanded.
