Publication number: 20230210520Abstract: A method of closing a patent foramen ovale (PFO) including a septum primum and septum secundum is implemented using a suture device including an operational shaft housing an anchor assembly, a needle assembly, and a suture. The method includes advancing an end of the operational shaft to a proximal side of the PFO, positioning a distal portion of the end of the operational shaft on a distal side of the PFO, and actuating the anchor assembly to deploy the anchor assembly on the distal side of the PFO. The method also includes actuating the needle assembly on the proximal side of the PFO to deploy the needle assembly through the PFO and the anchor assembly, thereby deploying the suture through the PFO. The method further includes retracting the anchor assembly into the operational shaft, and withdrawing the distal portion of the operational shaft from the PFO, leaving the deployed suture.Type: ApplicationFiled: December 29, 2022Publication date: July 6, 2023Inventors: Theodore P.

Patent number: 9492277Abstract: Soft body tissue structure can be remodeled by shortening the distance between first and second portions of that tissue structure. First and second anchor structures are respectively implanted in the first and second portions of the tissue structure. These anchor structures are linked by a linking structure, the length of which between the anchor structures can be shortened to pull the tissue structure portions toward one another. Each of the anchor structures may include two screw structures that are driven into the associated tissue structure portion transverse to the linking structure and with a spacer between the two screws. The entire prosthesis can be implanted percutaneously if desired. An illustrative use of the prosthesis is to shorten the annulus of a patient's mitral valve, with at least a portion of the prosthesis implanted in the patient's coronary sinus.Type: GrantFiled: August 30, 2005Date of Patent: November 15, 2016Assignee: MAYO FOUNDATION FOR MEDICAL EDUCATION AND RESEARCHInventors: Paul J.

Publication number: 20160095701Abstract: A prosthetic mitral valve includes a collapsible and expandable elliptical or āDā-shaped stent. The stent includes first and second commissure attachment features and a collapsible and expandable valve assembly disposed therein. The valve assembly includes two leaflets, each leaflet having a first edge operably coupled to the stent and a second free edge. Each leaflet may include first and second tabs connecting first and second ends of the first and second edges, respectively. Each leaflet includes a height measured from a midpoint of the first edge to a midpoint of the second edge and a width measured from a junction of the first edge with the first tab to a junction of the first edge with the second tab. The ratio of the height to the width may be between about 0.4 and about 0.65.Type: ApplicationFiled: September 30, 2015Publication date: April 7, 2016Inventors: Theodore P. Dale, Andrea N.

Patent number: 9101338Abstract: An implant structure for use in pulling two soft body tissue areas closer together in a patient (e.g., two points along or adjacent to the patient's mitral valve annulus) includes at least two tissue anchor structures that are respectively implantable into the two tissue areas. A tether structure links the two tissue anchors and can be shortened and held in that condition by a cinch structure. Bracing structures are used between the anchors and the tether to help keep the longitudinal axes of the anchors transverse to the tether axis even when the tether is under tension. The tether may be sheathed in a cushioning sleeve to help protect adjacent tissue from erosion by the tether.Type: GrantFiled: May 3, 2007Date of Patent: August 11, 2015Assignee: MAYO FOUNDATION FOR MEDICAL EDUCATION AND RESEARCHInventors: Paul J.

Patent number: 8920434Abstract: Apparatus is provided that can be delivered through a catheter to a remote location in a patient's body. The apparatus may include a first structure that can be positioned in all dimensions in a controlled manner and stabilized in that desired position, a second structure that can then position a lumen axis at a desired angle relative to the first structure, and a third member that can pass through the lumen and approach and engage with force (e.g., penetrate) a desired location on the anatomy without compromising maintaining the desired position. The apparatus effectively separates the forces needed for positioning and the forces needed for tissue engagement (e.g., penetration).Type: GrantFiled: February 23, 2006Date of Patent: December 30, 2014Assignee: St. Jude Medical, Cardiology Division, Inc.Inventors: Michael P Brenzel, Theodore P Dale, David M Costello, Paul J Hindrichs

Patent number: 8882787Abstract: A structure that can be used to provide an anchor in or adjacent to a patient's soft body tissue (rather than bone) includes an annular array of flexible members that extend between two axially spaced but aligned tubular members. The space between the tubular members can be selectively changed to affect the amount by which portions of the flexible members between the tubular member project radially outward relative to the tubular members. When the flexible members project radially out, the structure resists axial movement relative to adjacent tissue and therefore acts as an anchor. When the flexible members do not project radially out, they permit axial movement of the structure through adjacent tissue.Type: GrantFiled: February 23, 2006Date of Patent: November 11, 2014Assignee: St. Jude Medical, Cardiology Division, Inc.Inventors: Michael P Brenzel, Theodore P Dale, David M Costello, Paul J Hindrichs
