Publication number: 20230233313Abstract: Methods, apparatuses, and systems are described for stent delivery and positioning for transluminal application. The method may include positioning the stent in an undeployed configuration through an access site in a wall of a first body lumen. In some cases, the method may include retracting an outer sheath proximally and past an anchoring component disposed at a distal portion of an inner tubular member based on positioning the stent. A distal portion of the stent may be disposed between the anchoring component and the outer sheath while the stent is in the undeployed configuration. The method may further include deploying the distal portion of the stent from the outer sheath and within the first body lumen and expanding a proximal portion of the stent from within the outer sheath such that upon fully exiting the outer sheath, the proximal portion expands to a deployed configuration within a second body lumen.Type: ApplicationFiled: January 21, 2022Publication date: July 27, 2023Inventors: Siddhi K. Desai, Kevin M. Morris, Kee Sein Lee, Edward L. Carcamo, Alexander A. Lubinski

Publication number: 20230233349Abstract: Methods, apparatuses, and systems are described for stent delivery and positioning for transluminal application. The system may include a stent that is disposed coaxially onto an inner tubular member. In some cases, the system may include an outer sheath disposed coaxially along at least a portion of the inner tubular member. The system may include a distal cutting element coupled with a distal end of the inner tubular member and an anchoring component disposed at a distal portion of the inner tubular member. The anchoring component may be configured to retain a distal portion of the stent in place along the inner tubular member as the outer sheath is retracted proximally to deploy the stent, wherein upon retraction of the outer sheath, the stent releases from the anchoring component and expands into a deployed configuration within the body lumen.Type: ApplicationFiled: January 21, 2022Publication date: July 27, 2023Inventors: Siddhi K. Desai, Kevin M. Morris, Kee Sein Lee, Mark L. Stiger

Publication number: 20230233312Abstract: Apparatuses, and systems are described for stent designs for transluminal application. The stent may include a stent body having a diameter and a length in a deployed configuration. The stent may include a helical wrapping pattern that is at least partially covered with a material. The helical wrapping pattern may be configured to reduce a foreshortening of the stent body upon deployment from an undeployed configuration to the deployed configuration to less than ten percent of a length of the stent body in the undeployed configuration. In some cases, the stent may include a first anchoring member coupled with a distal portion of the stent body and a second anchoring member coupled with a proximal portion of the stent body. The first and second anchoring members may be configured to increase a diameter of the stent.Type: ApplicationFiled: January 21, 2022Publication date: July 27, 2023Inventors: Siddhi K. Desai, Ailee T. Pham

Patent number: 11484684Abstract: A system for delivering a fluid to a Eustachian tube (ET) of a patient includes a guide member and a tubular member. The guide member includes a shaft having a proximal portion, a distal portion, and a bend at the distal portion. The bend is configured to provide access to an opening in the ET. The system further includes a tubular member comprising a proximal end, a distal end, and a lumen extending therebetween. The tubular member is sized to fit within the ET. One or both of the tubular member and the guide member comprises a first stop member configured to engage the other of the tubular member or the guide member. The first stop member is configured to restrict a distal advancement of the tubular member relative to the guide member.Type: GrantFiled: September 18, 2018Date of Patent: November 1, 2022Assignee: Acclarent, Inc.Inventors: Siddhi K. Desai, Hung V. Ha, Ketan P. Muni, Randy S. Chan, Andy Nguyen, Mina W. Chow, Mei Pader

Patent number: 10300257Abstract: A dilation assembly includes a shaft and a dilator coupled with the distal end of the shaft. The dilator includes a proximal end, a distal end, and a center portion positioned between the proximal end and the distal end. The center portion dilates from a first configuration to a second configuration. The center portion has a larger diameter than the proximal end and the distal end when the center portion is in the second configuration. At least one gripping feature is positioned on at least a portion of the exterior surface of the center portion. The gripping feature provides friction between the center portion and a bodily lumen when the center portion is in the second configuration.Type: GrantFiled: March 29, 2016Date of Patent: May 28, 2019Assignee: Acclarent, Inc.Inventors: Show-Mean Wu, Tapan Mistry, Dexter D.

Patent number: 10143591Abstract: A system and method for dilating a Eustachian tube of a patient is disclosed. The device includes a protective sheath, a flexible endoscope and a balloon dilation catheter. The protective sheath includes an endoscope lumen and a balloon dilation catheter lumen. The balloon of the balloon dilation catheter is a low profile balloon particularly useful for dilating the Eustachian tube, and in particular, the Eustachian tube of a pediatric patient. The method involves advancing the balloon dilation catheter through a nasal passage of the patient to dilate a portion of the Eustachian tube.Type: GrantFiled: September 11, 2015Date of Patent: December 4, 2018Assignee: Acclarent, Inc.Inventors: Hung V. Ha, Ketan P. Muni, Andrew Nguyen, Siddhi K. Desai, Ronak Muni

Patent number: 10137285Abstract: An apparatus includes a handle assembly, a guide assembly, and a dilation catheter. The guide assembly extends distally from the handle assembly. The guide assembly includes a malleable guide member and a flexible guide member. The distal end of the flexible guide member is distal to the distal end of the malleable guide member. The flexible guide member is positioned about the malleable guide member and is slidable along the malleable guide member. The dilation catheter is slidably disposed about the flexible guide member.Type: GrantFiled: August 12, 2015Date of Patent: November 27, 2018Assignee: Acclarent, Inc.Inventors: Thomas R. Jenkins, Randy J. Kesten, Siddhi K. Desai
