Publication number: 20230115266Abstract: The disclosure relates to cannulae, delivery systems, methods of making cannulae, and methods of making delivery systems. A delivery system comprises an elongate outer tubular member defining an outer tubular member lumen, a cannula having a circumferential wall extending between a proximal end and a distal end and defining an interior lumen, and an intraluminal medical device disposed within the outer tubular member lumen distal to the cannula and not about the cannula. A pattern of openings arranged in an interrupted spiral extends circumferentially along the cannula.Type: ApplicationFiled: December 12, 2022Publication date: April 13, 2023Applicant: Cook Medical Technologies LLCInventors: Joshua Frye Krieger, Melissa Lonn

Patent number: 10321984Abstract: A cannula cut spiral flow inducing stent includes a plurality of spiral inducing flow diverters that each include a piece of sheet metal with a helically shaped flow surface. A proximal stent region, which includes a plurality of first struts, is joined to a proximal end of each of the spiral inducing flow diverters. A distal stent region, which includes a plurality of second struts, is joined to a distal end of each of the spiral inducing flow diverters. All of the first struts and all of the second struts share a cannula thickness, but the shaped pieces of sheet metal may have a lesser thickness.Type: GrantFiled: December 16, 2016Date of Patent: June 18, 2019Assignee: Cook Medical Technologies LLCInventors: Melissa Lonn, Adam Shields, Keith Milner, Seoggwan Kim

Publication number: 20180289521Abstract: A stent delivery system may include a stent disposed between an inner tubular member and an outer tubular member as part of a pre-delivery package for the stent. Once the pre-delivery package is disposed over a wire guide, the inner tubular member may be withdrawn through an opening in a pusher, which is then used to push the stent through a catheter lumen to a treatment site.Type: ApplicationFiled: April 6, 2018Publication date: October 11, 2018Applicant: Cook Medical Technologies LLCInventor: Melissa Lonn

Patent number: 10022252Abstract: A spiral blood flow device includes a stent made up of a plurality of expansion members joined to a plurality of axial members that permit the stent to change diameter among a continuum of expanded configurations. The axial members have fixed orientation, whereas the expansion members have a variable orientation relative to the longitudinal axis throughout the continuum of expanded configurations. A spiral flow inducing structure, which may include fins attached to the axial members, define a helical flow angle that remains constant throughout the continuum of expanded configurations.Type: GrantFiled: February 1, 2016Date of Patent: July 17, 2018Assignee: Cook Medical Technologies LLCInventors: Adam Shields, Keith Milner, Melissa Lonn
