Patent number: 11937810Abstract: Systems, devices and methods described herein relate to endovascular devices for delivering sutures for securing grafts or other objects to patient vessels. In some embodiments, a suture includes a set of two legs having proximal ends joined to each other and elongate bodies that extend parallel to one another such that the set of two legs form a U-shaped structure. A suture delivery system can include a housing configured to contain a suture in a flattened configuration, and a deployment element having a ribbon-shaped distal portion disposed in the housing and including a set of formations, where the housing and the set of formations of the deployment element are configured to collectively constrain the suture in the flattened configuration until the suture is released through the opening of the housing.Type: GrantFiled: May 23, 2023Date of Patent: March 26, 2024Assignee: Vesteck, Inc.Inventors: John K.

Publication number: 20240024627Abstract: A device is provided for preventing buckling of a flexible elongate member during insertion of the flexible elongate member. The device includes a support frame comprising a first end, a second end, and multiple pairs of support members. The support frame is configured to reversibly move from a collapsed configuration to an expanded configuration when the first and second ends are moved away from each other. The device also includes multiple open channels coupled to the multiple pairs of support members of the support frame. The multiple open channels are configured to allow the flexible elongate member to be top loaded into the multiple open channels. Also, the multiple open channels are maintained in an axial alignment as the support frame is moved between the expanded and collapsed configurations.Type: ApplicationFiled: May 16, 2023Publication date: January 25, 2024Inventors: Arkady Kokish, Kent Stalker, Jason J.

Publication number: 20220218459Abstract: A blood filter having a support structure and a filter structure. Various embodiments of the filtering assemblies may be utilized as a temporary implant or a permanent implant. The support structure, which serves as an anchor for the blood filter may define a larger porosity. The filter structure may define a smaller porosity, the smaller pores of which prevent emboli from passing therethrough. The support and filter structures may be made separately and assembled. In some embodiments, the filter structure actively slides on the support structure to accommodate the collapsing and deployment of the filter assembly. In some embodiments, a polymer film is selectively applied to the filter structure to provide a more uniform porosity over an outer bend radius of the filter structure. In some embodiments, the filter assembly is shaped to conform to the contours of the aortic arch while enabling self-cleaning of the filter structure.Type: ApplicationFiled: May 18, 2020Publication date: July 14, 2022Inventors: Vitali VERIN, Olivier COQUOZ, Alexandre ROMOSCANU, Duncan KEEBLE, Kent STALKER

Publication number: 20070208374Abstract: An embolic protection device for use in a blood vessel when an interventional procedure is being performed in a stenosed or occluded region to capture any embolic material which may be created and released into the bloodstream during the procedure. The device includes a filtering assembly having a self-expanding strut assembly and a filter element attached thereto. In one embodiment, the filtering assembly is attached to the distal end of a guide wire and is deployed within the patient's vasculature as the guide wire is manipulated into the area of treatment. A restraining sheath placed over the filtering assembly in a coaxial arrangement maintains the filtering assembly in its collapsed position until it is ready to be deployed by the physician. Thereafter, the sheath can be retracted to expose the filtering assembly which will then self-expand within the patient's vasculature.Type: ApplicationFiled: May 11, 2007Publication date: September 6, 2007Applicant: ADVANCED CARDIOVASCULAR SYSTEMS, INC.Inventors: William Boyle, Andy Denison, Benjamin Huter, Scott Huter, Richard Stack, Kent Stalker, Christopher Tarapata, John Whitfield

Publication number: 20070156169Abstract: An expandable frame for an embolic filtering device used to capture embolic debris in a body vessel includes a first half frame having a first control arm connected to a second control arm by a partial loop and a second half frame having a first control arm connected to a second control arm by a partial loop. The partial loops cooperatively form a composite loop for attachment of a filtering element which will expand in the body vessel to capture embolic debris entrained in the fluid of the vessel. The lengths and positioning of the first and second control arms of each half frame can be varied to create an expandable frame which conforms to the size and shape of the body vessel in which the filtering device is deployed. Additionally, the radius of the partial loops, along with the length of the arc of the partial loops, can be varied on each of the frames to create a composite filtering assembly that can easily adapt to the size and shape of the body vessel.Type: ApplicationFiled: January 17, 2007Publication date: July 5, 2007Inventors: Andy Denison, William Harrison, Benjamin Huter, Scott Huter, John Papp, Steven Saville, Kent Stalker
