Abstract
Medical devices, systems and methods for occluding a left atrial appendage of a heart are provided. In one embodiment, the medical device includes an occluder portion and an anchor portion that are pivotably coupled to each other with hinge components. The hinge components each include a base with arms extending from the base such that the arms of each one of the hinge components extend through and capture a first eyelet of the occluder portion and a second eyelet of the anchor portion to facilitate pivotably coupling the anchor portion to the occluder portion.
Claims21
A medical device for occluding a left atrial appendage of a heart, comprising:
- an occluder portion coupled to a hub defining an axis, the occluder portion having occluder frame segments extending radially outward from the hub to a distal end portion of the occluder portion, multiple ones of the occluder frame segments at the distal end portion define a first eyelet;
- an anchor portion having anchor frame segments, the anchor frame segments extending between first and second ends, the second end of the anchor frame segments coupled to an anchor hub and the first end of the anchor frame segments define a second eyelet adjacent thereto;
- and
- multiple hinge components, each of the hinge components including a base with arms extending from the base such that the arms of each one of the hinge components extend through and capture the first eyelet and the second eyelet of one of the occluder frame segments and one of the anchor frame segments, respectively, to facilitate pivotably coupling the anchor portion to the occluder portion.
A medical device for occluding a left atrial appendage of a heart, comprising:
- a framework having an occluder portion and an anchor portion, the occluder portion coupled at a hub such that the occluder portion of the framework extends radially outward relative to the hub to a distal end portion of the occluder portion, the anchor portion extending between a first end portion and a second end portion, the second end portion coupled to a secondary hub;
- and
- multiple hinge components, each of the hinge components including a base with arms extending from the base such the arms of each one of the hinge components extend through eyelets defined in the distal end portion and the first end portion of the occluder portion and the anchor portion, respectively, to facilitate pivotably coupling the anchor portion to the occluder portion.
A method of occluding a left atrial appendage of a heart, the method comprising:
- advancing a medical device with a catheter through a vasculature and to the left atrial appendage, the medical device having a framework extending between a primary hub and a secondary hub, the primary hub and the secondary hub having a common axis, the framework extending with hinge components between an occluder portion and an anchor portion of the framework such that each of the hinge components includes a base and arms extending from the base;
- deploying the framework adjacent the left atrial appendage from a constricted position to a deployed position such that the secondary hub is moveable along the axis relative to the primary hub and such that the anchor portion pivots about the hinge components with the arms of each of the hinge components positioned through corresponding ones of an anchor eyelet defined in the anchor portion and the arms of each of the hinge components positioned through corresponding ones of an occluder eyelet defined in the occluder portion;
- and
- releasing the medical device from the catheter with the framework of the medical device secured to tissue adjacent the left atrial appendage.
A medical device for occluding a left atrial appendage of a heart, comprising:
- a framework extending to define an occluder portion and an anchor portion, the anchor portion including tines sized and configured to anchor the framework to tissue of the left atrial appendage, the anchor portion pivotably coupled to the occluder portion with multiple hinge components such that each one of the hinge components extend through and are captured within a first eyelet of the occluder portion and a second eyelet of the anchor portion to facilitate pivotably moving the anchor portion relative to the occluder portion;
- wherein the hinge components and portions adjacent the tines of the anchor portion comprise a radiopaque material, the radiopaque material of the hinge components defining a proximal boundary and the radiopaque material of the portions adjacent the tines define a distal boundary, the proximal and distal boundaries spaced relative to each other to define a landing zone therebetween.
