Publication number: 20220226133Abstract: A stent made from a material comprising a polymer is disclosed. The stent has a pre-crimp diameter and a wall thickness such that a ratio of the pre-crimp diameter to the wall thickness is between 30 and 60. The stent has a pattern of interconnected elements. The interconnected elements including a plurality of rings connected by links, wherein each ring includes struts and crowns, and the struts are configured to fold at the crowns when the stent is crimped to the balloon.Type: ApplicationFiled: April 6, 2022Publication date: July 21, 2022Inventors: Mikael Trollsas, Michael H.

Patent number: 11324614Abstract: A medical device includes a polymer stent (or scaffold) crimped to a catheter balloon. The stent, after being expanded from a crimped state by the balloon, provides a crush recovery of about 90% of its expanded diameter after being pinched or crushed by an amount equal to about 50% of the expanded diameter. The stent has a pattern including a W-shaped or W-V shaped closed cell and links connecting the closed cells.Type: GrantFiled: October 26, 2018Date of Patent: May 10, 2022Assignee: ABBOTT CARDIOVASCULAR SYSTEMS INC.Inventors: Mikael Trollsas, Michael H.

Patent number: 10123894Abstract: A method of crimping a stent is disclosed. The stent includes a minimum crimped diameter such that in the minimum crimped diameter, a pair of stent rings, between which marker support structures reside, do not make contact with the marker support structures. The crimped profile of the stent of the present invention can be as small as the crimped profile of a same stent but without the maker support structures.Type: GrantFiled: September 8, 2017Date of Patent: November 13, 2018Assignee: Abbott Cardiovascular Systems Inc.Inventors: Mikael Trollsas, Michael H.

Patent number: 9827119Abstract: A medical device includes a polymer scaffold crimped to a catheter having an expansion balloon. The scaffold, after being deployed by the balloon, provides a crush recovery of about 90% after the diameter of the scaffold has been pinched or crushed by 50%. The scaffold also has a reduced crimped profile and a modification of the scaffold's ring structure at the crowns that contributes to the reduced crimped profile.Type: GrantFiled: July 3, 2014Date of Patent: November 28, 2017Assignee: ABBOTT CARDIOVASCULAR SYSTEMS INC.Inventors: Boris Anukhin, Michael H.

Patent number: 9375304Abstract: An implantable lumen filter is described. The filter may include a body formed from an elongate member. The body may include loops encircling an axis extending along the length of the body. The body may be sized to be implanted into a body lumen. The body may be capable of transitioning from a collapsed state to a deployed state. The filter may include a first group of a plurality of members positioned around at least one loop of said body. At least a portion of the plurality of members may be oriented towards the axis. The plurality of members may be arranged to capture and/or lyse particulates of a selected size and/or to inhibit the particulates from passing through the body. Methods to of making, deploying, and retrieving the same are described.Type: GrantFiled: April 2, 2015Date of Patent: June 28, 2016Assignee: ABBOTT LABORATORIES VASCULAR ENTERPRISES LIMITEDInventors: Boris Anukhin, David Mackiewicz, Michael L.
