Patent number: 12589013Abstract: 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: GrantFiled: August 3, 2022Date of Patent: March 31, 2026Assignee: Advanced Bifurcation Systems Inc.Inventors: Ashur Bourang, Henry Bourang

Publication number: 20260026950Abstract: The present disclosure relates to a method for deploying a side branch stent in a bifurcated vessel that already contains a pre-existing main branch stent. The method involves inserting guide wires into both the main and side branches, and advancing a dual catheter delivery system, where only the side branch catheter carries the side branch stent. The system is retracted to position behind a side hole of the pre-existing stent, and guide wires are adjusted to reduce crossing. The catheters are aligned using marker bands and advanced towards the bifurcation until a specific tension is achieved. A balloon on the side branch catheter is then inflated to deploy the side branch stent through the side hole. This is followed by a kissing balloon inflation for optimal stent apposition. The catheters are then deflated and removed, leaving the stents aligned without gaps, ensuring effective treatment of the bifurcation.Type: ApplicationFiled: July 23, 2024Publication date: January 29, 2026Inventors: Ashur Bourang, Henry Bourang

Publication number: 20260014008Abstract: A system and method for treating a bifurcated vessel may include a mother catheter with a mother expandable member coupled to a distal portion of a mother elongate shaft. A daughter catheter has a daughter expandable member coupled to a distal portion of a daughter elongate shaft. A therapeutic agent is carried on the daughter expandable member. Radial expansion of the daughter expandable member engages the daughter expandable member with a wall of the daughter vessel and the therapeutic agent elutes from the daughter expandable member into the wall.Type: ApplicationFiled: July 11, 2025Publication date: January 15, 2026Inventors: Ashur Bourang, Henry Bourang

Publication number: 20250195248Abstract: 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: March 6, 2025Publication date: June 19, 2025Inventors: Ashur Bourang, Henry Bourang

Publication number: 20250170368Abstract: 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: January 28, 2025Publication date: May 29, 2025Inventors: Ashur Bourang, Henry Bourang

Publication number: 20240325180Abstract: 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 the 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. A twist resolution pocket is provided on the first and second delivery catheters.Type: ApplicationFiled: March 30, 2023Publication date: October 3, 2024Inventors: Ashur Bourang, Henry Bourang
