Publication number: 20240000448Abstract: A first end of a wire is transluminally penetrated through tissue at a first cardiovascular site of a subject. A capture device is transluminally advanced into the subject, and is used to capture the first end of the wire and pull the first end of the wire away from the first cardiovascular site. From the first end of the wire, a first anchor is tracked along the wire, and is then anchored to the tissue at the first cardiovascular site. A second anchor is anchored to tissue at a second cardiovascular site. Subsequently, the first and second cardiovascular sites are drawn together by applying tension between the first and second anchors. Other embodiments are also described.Type: ApplicationFiled: September 17, 2023Publication date: January 4, 2024Inventors: Adam Groothuis, Steven D. Cahalane, Richard J. Morrill, John Alexander

Patent number: 11793505Abstract: A first end of a wire is transluminally advanced to a location adjacent an atrium of a heart of a subject, while a second end of the wire remains disposed outside of the subject. From the location, the first end of the wire is penetrated through tissue into the atrium. A capture device is transluminally advanced into the atrium. Using the capture device, the first end of the wire is captured and pulled out of the subject. From the first end of the wire, a first anchor is tracked along the wire into the atrium, and is anchored to an annulus of a valve of the heart. A second anchor is advanced into the atrium, and is anchored to the annulus. Subsequently, the annulus is reshaped by applying tension between the first and second anchors.Type: GrantFiled: February 9, 2021Date of Patent: October 24, 2023Assignee: EDWARDS LIFESCIENCES CORPORATIONInventors: Adam Groothuis, Steven D. Cahalane, Richard J. Morrill, John Alexander

Patent number: 11540835Abstract: The present teachings provide methods for resizing, reducing, and/or closing an atrial appendage. A delivery catheter is percutaneously advanced to the atrial appendage. At least two tissue anchors are implanted in tissue of the heart. Both tissue anchors are pulled together so that the atrial appendage is resized, reduced, and/or closed. This closure method and system could be used alone in closing the atrial appendage. This closure method and system could also be used in addition to other treatment mechanisms.Type: GrantFiled: July 6, 2020Date of Patent: January 3, 2023Assignee: Edwards Lifesciences CorporationInventors: Adam Groothuis, Steven D.

Publication number: 20210228354Abstract: The disclosure provides valve prostheses and methods of installation. One embodiment of the prosthesis has a generally tubular body adapted for placement proximate a mitral annulus. The tubular body has a generally tubular upper portion adapted to substantially reside in the left atrium above the mitral annulus. The generally tubular upper portion has a first circumferential wall that is outwardly biased to urge against cardiac tissue of the left atrium. The tubular body also includes a lower portion extending downwardly from the generally tubular upper portion, the lower portion being configured to substantially reside in the left ventricle below the mitral annulus. The lower portion of this embodiment can be defined by an generally circumferential wall that extends downwardly from the generally tubular upper portion. The generally circumferential wall has a first circumferential end and a second circumferential end, and defines a circumferential extent therebetween.Type: ApplicationFiled: October 30, 2020Publication date: July 29, 2021Inventors: Nasser Rafiee, G. Randall Green, Adam Groothuis

Patent number: 10918374Abstract: The present teachings provide devices and methods of treating a tricuspid valve regurgitation. Specifically, one aspect of the present teachings provides devices and methods of identifying a suitable location on the tricuspid annulus, another aspect of the present teachings provides devices and methods of placing a wire across the tricuspid annulus at such an identified location, another aspect of the present teachings provides devices and methods of deploying a tissue anchor across such an identified location, and yet another aspect of the present teachings provides devices and methods of applying tension to two or more of such tissue anchors and reducing the circumference of the tricuspid annulus. As a result, a regurgitation jet is reduced or eliminated.Type: GrantFiled: November 8, 2018Date of Patent: February 16, 2021Assignee: Edwards Lifesciences CorporationInventors: Adam Groothuis, Steven Cahalane, Richard Morrill, John Alexander

Publication number: 20210015615Abstract: A partial valve prosthesis includes a framework configured for following a shape of a portion of the native valve annulus when implanted into the native valve annulus, the framework including securement features for anchoring the framework to an inner periphery of the native valve annulus and retaining at least one leaflet configured to replace a corresponding one of the plurality of native leaflets; and at least one leaflet secured to the framework. Additional embodiments and methods are disclosed.Type: ApplicationFiled: July 30, 2020Publication date: January 21, 2021Inventors: Adam Groothuis, Adrian Ebner, Peter Markham, Elazer Edelman

Publication number: 20200352715Abstract: The present embodiments relate to systems and methods for treating luminal valves. Particularly, and in accordance with one aspect, the present disclosure is directed to methods and systems for partial or complete replacement of luminal valves. An exemplary catheter in accordance with the disclosure includes an elongate body having a proximal end and a distal end, and a retractable sheath mounted on the elongate body proximate the distal end. The sheath and elongate body cooperating to define a first annularly-shaped compartment between the body and sheath. The catheter further includes a valve prosthesis mounted in the compartment, the prosthesis having proximal and distal ends connected to a means for deploying the valve prosthesis from the catheter.Type: ApplicationFiled: July 30, 2020Publication date: November 12, 2020Inventors: Adam Groothuis, Adrian Ebner, Peter Markham, Elazer Edelman

Patent number: 10702274Abstract: The present teachings provide methods for resizing, reducing, and closing left atrial appendage. Specifically, a percutaneous trans-septal access is first established from outside the body to a patient's LAA. At least two tissue anchors are then implanted inside the LAA chamber and along the tissue wall. At least one anchor is implanted near the opening of the LAA camber. Both tissue anchors are pulled together so that the wall of the LAA chamber collapse. The LAA chamber is therefore resized, reduced, and/or closed off completely. This closure method and system could be used alone in closing LAA chamber. This closure method and system could also be used in addition to other treatment mechanisms, such as filling the LAA chamber with space-filling material, then closing off its opening.Type: GrantFiled: May 26, 2017Date of Patent: July 7, 2020Assignee: Edwards Lifesciences CorporationInventors: Adam Groothuis, Steven D.
