Publication number: 20190159918Abstract: A system for treating a bifurcation includes first and second delivery catheters. The first catheter has a first shaft, a first expandable member adjacent the distal end of the first shaft, an auxiliary expandable member disposed under the first expandable member, and a first radially expandable stent disposed over both the first expandable member and the auxiliary expandable member. The second delivery catheter has a second shaft, and a second expandable member adjacent the distal end of the second shaft. A portion of the second catheter is disposed under a portion of the first stent, and a portion of the second delivery catheter passes through a side hole in the first stent. The first stent is crimped over the first and second catheters such that the first stent remains attached to the first and the second catheters during advancement of the catheters through a blood vessel.Type: ApplicationFiled: January 29, 2019Publication date: May 30, 2019Inventor: Henry Bourang

Publication number: 20190151127Abstract: 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.Type: ApplicationFiled: January 18, 2019Publication date: May 23, 2019Inventors: Henry Bourang, Mehran Khorsandi

Publication number: 20190091017Abstract: A two-stage or component-based valve prosthesis that can be quickly and easily implanted during a surgical procedure is provided. The prosthetic valve comprises a support structure that is deployed at a treatment site. The prosthetic valve further comprises a valve member configured to be quickly connected to the support structure. The support structure may take the form of a stent that is expanded at the site of a native valve. If desired, the native leaflets may remain and the stent may be used to hold the native valve open. In this case, the stent may be balloon expandable and configured to resist the powerful recoil force of the native leaflets. The support structure is provided with a coupling means for attachment to the valve member, thereby fixing the position of the valve member in the body. The valve member may be a non-expandable type, or may be expandable from a compressed state to an expanded state.Type: ApplicationFiled: November 20, 2018Publication date: March 28, 2019Applicant: Edwards Lifesciences CorporationInventors: Stanton J.

Publication number: 20180200483Abstract: Articulation devices, systems, and methods for articulating elongate flexible structures can locally contract a flexible elongate frame or skeleton of an elongate flexible body such as a catheter. Balloons along one side of an axial segment of the elongate flexible body can be inflated so as to help define a resting shape of the elongate body. The skeleton may have pairs of corresponding axially oriented surface regions coupled to each other by a loop of a deformable helical coil structure. Balloons may be between the regions, and the pairs may be separated by an offset that increases when the axis of the skeleton is axially compressed. Inflation of the balloons can axially contract or shorten the skeleton adjacent the balloons so that the elongate body bends toward the balloons.Type: ApplicationFiled: February 17, 2017Publication date: July 19, 2018Inventors: Keith Phillip Laby, Henry Bourang, Mark D.
