Patent number: 10166131Abstract: Stent delivery system having a contracted delivery configuration and an expanded deployed configuration is provided. The stent delivery system includes a stent having a plurality of expandable elements and a plurality of interstices disposed between adjacent expandable elements, and a delivery catheter having an inflatable balloon including creases extending non-uniformly within the interstices of the stent in the contracted delivery configuration. Each crease defines a maximum radial height within a corresponding interstice, and the maximum radial heights of the creases vary. A method for stenting at a target site within a patient's vessel including providing a stent delivery system is also provided.Type: GrantFiled: March 2, 2016Date of Patent: January 1, 2019Assignee: ABBOTT LABORATORIES VASCULAR ENTERPRISES LIMITEDInventors: Michael Schwager, Martin Frei, Suk-Woo Ha

Patent number: 9295570Abstract: A method of making a stent delivery system is provided in which a delivery catheter has a balloon that extends non-uniformly into interstices of a stent. In accordance with the method a balloon/stent/crimping tube assembly is placed in a crimping tool, the balloon is inflated, and the crimping tool is actuated to compress the stent on the outside of the balloon without application of heat or chemicals, thereby causing creases of the balloon to extend non-uniformly into the interstices of the stent. Optionally, pillows may be formed in the balloon to prevent longitudinal movement of the stent with respect to the balloon during intravascular delivery. One or more secondary crimpings also may be performed to achieve a smoother delivery profile.Type: GrantFiled: February 23, 2005Date of Patent: March 29, 2016Assignee: ABBOTT LABORATORIES VASCULAR ENTERPRISES LIMITEDInventors: Michael Schwager, Martin Frei, Suk-Woo Ha

Patent number: 8709074Abstract: A device for treatment of mitral annulus dilation is disclosed, wherein the device comprises two states. In a first of these states the device is insertable into the coronary sinus and has a shape of the coronary sinus. When positioned in the coronary sinus, the device is transferable to the second state assuming a reduced radius of curvature, whereby the radius of curvature of the coronary sinus and the radius of curvature as well as the circumference of the mitral annulus is reduced.Type: GrantFiled: February 6, 2012Date of Patent: April 29, 2014Assignee: Edwards Lifesciences AGInventors: Jan Otto Solem, Per-Ola Kimblad, Randolf von Oepen, Bodo Quint, Gerd Seibold, Kenneth J.

Patent number: 8075616Abstract: A device for reshaping a cardiac valve (26), which is elongate and has such dimensions as to be insertable into a cardiac vessel (24). The device has two states, in a first state (K) of which the device has a shape that is adaptable to the shape of the vessel (24), and to the second state (k?) of which the device is transferable from said first state (K). Further, the device comprises a fixing means (22,23;22a,23a) for fixing the ends of the device within the vessel (24), when the device is first positioned therein, a shape-changing member (20;20a) for transferring the device to the second state (K?) by reshaping it, and a delay means (21;21a) for delaying said reshaping until the fixing of the ends of the device has been reinforced by keeping said device in said first state (K) until the delay means (21;21a) is resorbed.Type: GrantFiled: December 20, 2002Date of Patent: December 13, 2011Assignee: Edwards Lifesciences AGInventors: Jan Otto Solem, Per Ola Kimblad, Randolf von Oepen, Bodo Quint, Gerd Seibold, Kenneth J.

Publication number: 20090228100Abstract: An elongate body including a proximal and distal anchor, and a bridge between the proximal and distal anchors. The bridge has an elongated state, having first axial length, and a shortened state, having a second axial length, wherein the second axial length is shorter than the first axial length. A resorbable thread may be woven into the bridge to hold the bridge in the elongated state and to delay the transfer of the bridge to the shortened state. In an additional embodiment, there may be one or more central anchors between the proximal and distal anchors with a bridge connecting adjacent anchors.Type: ApplicationFiled: May 22, 2009Publication date: September 10, 2009Applicant: Edwards Lifesciences CorporationInventors: Jan Otto Solem, Per Ola Kimblad, Stevan Nielsen, Ib Joergenson, Bodo Quint, Gerd Seibold, Randolf Von Oepen, Suk-Woo Ha, Karl-Ludwig Eckert, Stefan Schreck, Sepehr Fariabi, Tommy Conzelmann
