Patent number: 9675479Abstract: Stents (10) that are implanted within or around a hollow organ, especially self-expanding stents, comprising several annular wall segments (11) which are provided with an elastic structure and are joined to each other by means of connecting elements (12), are often problematic because the length of said stents is modified due to compressive stress, tensile stress, or contraction thereof, potentially resulting in undesired displacement of the stent (10). In order to prevent such positional changes of an implanted stent (10), the inventive connecting elements (12) form at least one continuous longitudinal web (13) which is provided with at least one component in an axial direction for receiving compressive stress or tensile stress in a longitudinal direction.Type: GrantFiled: September 16, 2003Date of Patent: June 13, 2017Assignee: PFM MEDICAL AGInventor: Johannes Jung

Patent number: 9320629Abstract: A stent for positioning in a body lumen having a cylindrical shape extending along a longitudinal axis surrounded by a stent wall which defines a diameter of an axial passage communicating with openings on two opposite ends of the stent. The wall is configured so as to be elastic under tension whereupon an exertion of a tensile force acting on one of the ends of the stent in a longitudinal direction decreases the diameter of the stent, such that the stent may be removed.Type: GrantFiled: October 19, 2006Date of Patent: April 26, 2016Assignee: PFM MEDICAL AGInventor: Bernhard Kramann

Patent number: 8828051Abstract: A left atrial appendage occlusion device including an occluder disk configured to substantially prevent blood from at least one of entering and exiting the left atrial appendage, a middle portion including a coiled element and a first anchoring element. The coiled element connects to the occluder disk, has a substantially constant cross section and allows for variable length, variable orientation, and/or varied angles.
