Abstract: An implant includes a frame comprising a tubular body formed by a plurality of interconnected struts that are manufactured to reduce stresses and strains resulting from component interaction during chronic use. At least a portion of a longitudinal corner of one or more struts of the frame may be chamfered, rounded, or otherwise modified to distribute stresses experienced at the strut corner throughout the strut body. Chamfering and/or rounding corners along at least a portion of a strut of the frame may reduce stresses on the frame caused by interactions between the frame and other components of the implant. The implant may be manufactured by cutting (e.g., laser cutting) a plurality of struts from a tubular metal alloy, polymer, or the like forming the tubular body, and softening at least a portion of an edge of the strut by cutting, grinding, and/or micro-blasting the edges of the corner.

Abstract: A low profile implant, system and method of deployment includes a frame comprising an elongate body having ends that overlap to form an annular configuration of the frame. A circumference of the frame may be modified by varying an extent of the overlap between the ends of the elongate body. The elongate structure may extend through a sleeve of a number of respective anchor housings of the implant along a first axis, and anchors may be deployed through bores in the anchor housings along a second axis to secure the anchor housings to tissue. The implant may be deployed about and anchored to a valve annulus, and the circumference of the frame, and associated anchored tissue, may be adjusted to reconfigure the valve annulus.

Abstract: An implant for left atrial appendage closure includes an expandable framework having a proximal end coupled to a collar, a shaft disposed within the collar and axially moveable relative to the collar, and a lock coupled to the shaft. The expandable framework is configured to expand from a collapsed delivery configuration to an expanded deployed configuration. The lock includes an engagement member configured to move between a constrained configuration and a radially expanded configuration, where the engagement member is biased in the radially expanded configuration.

Abstract: An actuator sleeve includes resiliency features that may reduce chronic strain on valve annulus implants. The resiliency features may relate to one or more of a material, a manufacture, a dimension, and/or design attribute of the sleeve. In one aspect the resiliency features may allow deformation of the sleeve at frame interfaces to distribute forces to reduce the frame fatigue.

Abstract: Various embodiments of an implant delivery systems including at least one removable actuator to reshape a valve annulus are described. The systems may use the removable actuator to customize annular reshaping at a treatment site and withdraw the actuator from the treatment site following custom reshaping to provide a low profile annuloplasty implant.

Abstract: Solutions for reducing irritation and/or trauma which may result upon contact of an implanted implantable device with tissue surrounding or adjacent to the implantable device. Various embodiments include features which allow a tangential or otherwise atraumatic contact of the implantable device with the tissue, in contrast with a sharper contact which may occur with prior art implantable devices. The broad principles are applicable to annuloplasty devices, and have other broader applications as well.
