An occlusive implant system may include a catheter having a lumen extending therethrough, a core wire slidably and rotatably disposed within the lumen, the core wire having a threaded member disposed at a distal end, and a medical implant having an expandable frame, an occlusive element disposed on the frame, and a threaded insert coupled to a proximal portion of the frame, wherein the threaded member is removably coupled to the threaded insert.

Retrieval wire centering device

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.

Implantable device having rounded struts and method of manufacture

An occlusive medical implant having a frame actuatable between a collapsed delivery configuration and an expanded implanted configuration, the frame including a generally tubular portion with a threaded insert configured to removably attach to a threaded distal end of a core wire; an occlusive element disposed on the frame; where a proximal portion of the occlusive element and the proximalmost extent of the threaded insert are substantially coplanar with a plane defined by three or more proximalmost extents of the frame in the expanded implanted configuration.

Occlusive medical implant

A stent has a first end region, a middle region, and a second end region, each region including a plurality of strut columns. The stent includes at least one barb. Each barb in an expanded state is at an angle relative to the outer surface of the stent.

Stent with anti-migration features

The disclosure pertains to a handle assembly for a left atrial appendage occlusion device delivery system and methods of use therefor. The handle assembly includes a leadscrew mechanism for smooth, low backlash control of a delivery catheter for the left atrial appendage occlusion device and manipulation segments which allow one hand operation of the handle assembly.
