Example medical devices and methods of making example medical devices are disclosed. An example medical device includes a frame configured to be secured to cardiac tissue, wherein the frame includes a fatigue resistant nickel-titanium alloy that is heat set at a temp in the range of 450-550 degrees Celsius.

Medical devices having increased fatigue resistance

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

A method of making a vascular occlusion device may include cutting a tubular member to form an expandable frame including a first hub integrally formed with the expandable frame adjacent a first end of the expandable frame, and a plurality of longitudinally-oriented struts extending in a direction opposite the first end; heat-setting the expandable frame to define an expanded configuration of the expandable frame; sliding a constrainment member over the plurality of longitudinally-oriented struts, the constrainment member being formed using additive manufacturing technology; fixedly securing the constrainment member to the plurality of longitudinally-oriented struts to define a second hub of the expandable frame; and cutting the plurality of longitudinally-oriented struts adjacent the constrainment member and opposite the first end relative to the constrainment member.
