Occlusion device

An occlusion device comprising:

• a frame including a plurality of radially expandable struts, the struts being comprised of a tube having a proximal end extending to a distal end and a tubular wall defining a lumen formed therethrough, a plurality of cuts formed through the tubular wall define the plurality of struts, the plurality of cuts include a first set of cuts extending from a first collar at the proximal end of the tube to a second set of cuts, the second set of cuts extending from the first set of cuts to a second collar located between the proximal and distal ends of the tube, and a third set of cuts extending from the second collar to the distal end of the tube, the plurality of struts being biased to a radially expanded state, in the radially expanded state the frame includes a first conical portion defined by the first set of cuts, a second conical portion defined by the second set of cuts, and a third conical portion defined by the third set of cuts, each conical portion having an apex and a base, the first and second conical portions being joined at their respective first and second bases forming a bulbous portion of the frame, the first collar defining a first apex of the first conical portion and the second collar defining a second apex of the second conical portion, the third conical portion being arranged distally of the bulbous portion, wherein the second collar defines a third apex of the third conical portion and the device terminates with a third base of the third conical portion at the distal end of the tube, wherein the first set of cuts is formed in a first pattern, the second set of cuts is formed in a second pattern, and the third set of cuts is formed in a third pattern, the first pattern being different than the second pattern such that the struts of the first and second conical portions of the bulbous portion form different patterns.
