Publication number: 20230398007Abstract: 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.

Publication number: 20230040227Abstract: A stent delivery system for treating a bifurcated vessel includes a first elongate shaft with a first expandable member. A first stent having a side hole is disposed over the first expandable member. A second elongate shaft has a second expandable member. The second elongate shaft is slidably disposed under the proximal end of the first stent and extends out of the side hole. The first stent is fully crimped over a proximal portion and a distal portion of the first expandable member and a proximal portion of the second expandable member so as to prevent axial movement of the first stent relative to the first or second elongate shafts during delivery. Portions of the first or second expandable members may be pillowed to provide a protective barrier that prevents edges of the stent from catching on other objects.Type: ApplicationFiled: August 3, 2022Publication date: February 9, 2023Inventors: Ashur Bourang, Henry Bourang

Publication number: 20230042061Abstract: A system and method for a stent delivery system, the delivery system having a catheter and a balloon coupled to a distal portion of the catheter. The catheter with the radially expandable member is inserted into a cavity in a mold. Heat and pressure are applied for a period of time which inflates the balloon and imparts a shape memory to a portion of the balloon. The balloon is removed from the cavity of the mold with a shape memory.Type: ApplicationFiled: August 11, 2022Publication date: February 9, 2023Inventors: Ashur Bourang, Henry Bourang

Publication number: 20220409409Abstract: A system for treating a bifurcated vessel that includes a first delivery catheter and a second delivery catheter. The first delivery catheter carries a proximal first stent and a distal second stent. The first delivery catheter also has a first elongate shaft, a proximal first expandable member with the proximal first stent disposed thereover, and a distal second expandable member with the distal second stent disposed thereover. The proximal first expandable member and distal second expandable member are independently expandable of one another. The second delivery catheter carries a third stent. The second delivery catheter also has a second elongate shaft, and a third expandable member with the third stent disposed thereover. The third expandable member is independently expandable of the proximal first expandable member and the distal second expandable member.Type: ApplicationFiled: August 29, 2022Publication date: December 29, 2022Inventor: Henry Bourang

Publication number: 20220346990Abstract: 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: July 20, 2022Publication date: November 3, 2022Inventors: Henry Bourang, Mehran Khorsandi

Publication number: 20220265451Abstract: 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.Type: ApplicationFiled: March 9, 2022Publication date: August 25, 2022Inventors: Henry Bourang, Mehran Khorsandi

Publication number: 20220226612Abstract: An elongate shaft management device has an upper plate and a lower plate. The lower plate has at least one groove that is sized to receive the elongate shaft. The at least one groove in the lower plate cooperates with the upper plate to capture the elongate shaft and prevent movement of the elongate shaft. The upper plate is releasably coupled to the lower plate to provide access to the elongate shaft and allow it to be manipulated.Type: ApplicationFiled: April 7, 2022Publication date: July 21, 2022Inventors: Ashur Bourang, Henry Bourang

Publication number: 20220211497Abstract: 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: March 25, 2022Publication date: July 7, 2022Applicant: Edwards Lifesciences CorporationInventors: Stanton J.
