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.

Publication number: 20210338460Abstract: A temporary expandable tissue support device includes a plurality of helical filaments superimposed on top of one another to form a tubular body. A first end of the tubular body is coupled to an inner shaft, and a second end of the tubular body is coupled to an outer shaft slidably disposed over the inner shaft. Actuation of the inner and outer shafts in a first direction compresses the plurality of filaments thereby radially expanding the tubular body into an expanded configuration adapted to engage and support tissue at a treatment site without obstructing a fluid from flowing past the tubular body. Actuation of the shafts in a second direction opposite the first direction tensions the plurality of filaments thereby radially collapsing the tubular body into a collapsed configuration that is adapted to be delivered to or removed from the treatment site.Type: ApplicationFiled: July 16, 2021Publication date: November 4, 2021Inventors: Alexander Nikanorov, Hugh Qinghong Zhao

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: 9884387Abstract: A method and a device for inductive radiofrequency welding of metal products, include heating by inducing radiofrequency currents with use of at least one induction conductor. The metal products and a welding zone are moved relative to one another, so that edge regions of the metal products to be welded are brought in contact in the welding zone and are welded together to form a weld seam. Metal products with different material thicknesses and/or material properties can be welded together because an induction conductor which heats the edge regions of the metal products is used which includes at least two mutually separable induction conductor components that are assigned to the respective metal product and are adapted thereto, and the edge regions to be welded are heated in a manner that is adjusted separately for the respective metal product.Type: GrantFiled: January 22, 2007Date of Patent: February 6, 2018Assignee: WISCO Tailored Blanks GmbHInventors: Jens Plha, Martin Koch, Stefan Wischmann, Bernhard Nacke, Alexander Nikanorov, Holger Schülbe, Mario Schmidt, Henning von Löhneysen

Patent number: 9259305Abstract: A guide wire locking mechanism for a catheter system includes a motion-limiting component adapted to contact a portion of a guide wire and limit the direction of motion that the guide wire can slide therethrough. The motion-limiting component allows the guide wire to slide in one direction when placed in the locking mechanism but prevents the guide wire from moving in the opposite direction. The motion-limiting component can be made from a row of movable teeth having contact surfaces or faces which come in contact with a portion of the guide wire. The teeth are bendable to allow the guide wire to move in one direction but will tighten against the guide wire if one attempts to move the guide wire in an opposite direction.Type: GrantFiled: March 31, 2005Date of Patent: February 16, 2016Assignee: ABBOTT CARDIOVASCULAR SYSTEMS INC.Inventors: Gregory W.
