Publication number: 20140336699Abstract: Disclosed is an occlusion device for use in a body lumen such as the left atrial appendage. The occlusion device includes an occlusion member and may also include a stabilizing member. The stabilizing member inhibits compression of the left atrial appendage, facilitating tissue in-growth onto the occlusion member. Methods are also disclosed.Type: ApplicationFiled: May 12, 2014Publication date: November 13, 2014Inventors: Erik J. van der Burg, Dino De Cicco, Andrew G.C. Frazier, Marc S. Kreidler, Michael D. Lesh, Chad C. Roue, Alexander K. Khairkhahan

Publication number: 20140309724Abstract: A stent design reduces the likelihood of contact among structural members when the stent diameter is reduced before insertion into the body. In one approach, an undulating link has a J-shaped profile or has an angled portion on one side at the peak of the link, in order to reduce contact during crimping. The stent may also include structural features that improve such aspects as flexibility, the coatibility of a drug coating onto the stent, flare reduction, stent retention within the body and/or reduction of the minimum diameter of the stent during crimping.Type: ApplicationFiled: June 25, 2014Publication date: October 16, 2014Inventors: Marc S. Kreidler, Jessica P. Miller

Patent number: 8834519Abstract: A device and method for obliterating or occluding a body cavity or passageway, in particular, the left atrial appendage of a patient's heart. The procedure can be carried out intraoperatively, but is preferably carried out percutaneously by use of a delivery catheter to position an occluding device adjacent a patient's left atrial appendage. The occluding device may prevent the passage of embolic or other material to or from the left atrial appendage by volumetrically filling the appendage, closing the opening of the appendage with an occluding member, or pulling the tissue around the opening of the appendage together and fixing it in a closed state.Type: GrantFiled: November 18, 2011Date of Patent: September 16, 2014Assignee: Artritech, Inc.Inventors: Erik J. van der Burg, Dino De Cicco, Andrew G. C. Frazier, Alexander K. Khairkhahan, Marc S. Kreidler, Michael D. Lesh, Chad C. Roue

Publication number: 20120239083Abstract: A method of preventing ingress of material into the left atrium of a heart includes providing a delivery sheath, advancing the sheath distal end through an opening between the right atrium and the left atrium of the heart, providing an expandable cage, delivering the expandable cage to the left atrium, and expanding the expandable cage within the left atrium. The expandable cage includes a proximal end, a distal end, and a plurality of supports extending therebetween. The expandable cage also includes a first membrane provided at its proximal end and a second membrane provided at its distal end. The expandable cage has a collapsed configuration so that it can be received within the lumen of the delivery sheath, and an expanded configuration for deployment within the heart. When expanded, the first membrane is positioned at an opening between the left and right atria of the heart, and the second membrane is positioned at the ostium of the left atrial appendage.Type: ApplicationFiled: May 26, 2011Publication date: September 20, 2012Applicant: ATRITECH, INC.Inventor: Marc S.
