Publication number: 20210290248Abstract: This application describes various embodiments of an expandable device that includes at least one support member. The support member (or members) is integrated into the structure of the expandable device and increases its column strength, which thus augments pushability of the expanding device through a delivery catheter. The support member allows force applied while pushing from the proximal end of the expandable device to be translated to the distal end of the device and therefore avoid bunching or deformation without increasing the profile of the device to a degree that would prohibit passage through a lumen of a specific required size. Thus, the expandable devices described herein address at least some of the shortcomings discussed above.Type: ApplicationFiled: March 16, 2021Publication date: September 23, 2021Inventors: John Oslund, Pat Russo, Kevin Dunne

Patent number: 9445798Abstract: A collapsible medical device and associated methods of occluding an abnormal opening in, for example, a body organ, wherein the medical device is shaped from plural layers of a heat-treatable metal fabric. Each of the fabric layers is formed from a plurality of metal strands and the assembly is heat-treated within a mold in order to substantially set a desired shape of the device. By incorporating plural layers in the thus-formed medical device, the ability of the device to rapidly occlude an abnormal opening in a body organ is significantly improved.Type: GrantFiled: January 17, 2014Date of Patent: September 20, 2016Assignee: St. Jude Medical, Cardiology Division, Inc.Inventors: Kurt Amplatz, Matt Glimsdale, Jana Santer, Derek Wise, John Oslund, Kent Anderson, Daniel O.

Patent number: 9402634Abstract: A vascular device is provided that includes a tubular structure and an occluding structure. The tubular structure has inner and outer layers, with the occluding structure located between the inner and outer layers. Each of the inner and outer layers may define a different pick count, and the tubular structure may include a leading edge at a transition between the pick counts. The leading edge may be disposed at the distal end of the vascular device when the device is deployed from a delivery device. Furthermore, the occluding structure may have first and second layers formed by the inversion or eversion of the occluding structure and the subsequent coupling of its free ends to form a continuous structure. Thus, any loose ends may be sealed to minimize unraveling and/or shifting of the occluding structure within the tubular structure. A method of making the vascular device is also provided.Type: GrantFiled: November 26, 2013Date of Patent: August 2, 2016Assignee: ST. JUDE MEDICAL, CARDIOLOGY DIVISION, INC.Inventors: Patrick Russo, John Oslund, Matthew C. Heidner, Jessica Akers
