Abstract: The present disclosure is directed to embodiments of an occlusive medical device including a frame and at least one closure coupled to the frame. The frame includes a distal annular flange having a radially outer surface and a radially inner surface, a proximal annular flange having a radially outer surface and a radially inner surface, and a waist portion extending between and connecting the distal annular flange to the proximal annular flange. The radially inner surface of the distal annular flange, the waist member, and the radially inner surface of the proximal annular flange define an unobstructed passageway through the frame. The at least one closure is configured to close the passageway to: (i) provide an occlusive effect, and (ii) enable subsequent access through the passageway.

Abstract: Doormat assembly comprising a base including a central area and a peripheral area surrounding the central area, a frame assembly formed separately from the base and forming a frame with a central opening for exposing the central area of the base, and a removable insert unsecured to the base and sized to fit within the central opening of the frame assembly so as to cover the central area of the base, wherein the frame assembly comprises a plurality of side members and a plurality of corner portions engaged with the side members to form the frame, and wherein the removable insert is removable through the central opening in the frame and replaceable.

Abstract: Doormat assembly comprising a base including a central area and a peripheral area surrounding the central area, and having an upper surface and an opposing lower surface, a frame assembly overlapping with at least a portion of the upper surface of the peripheral area of the base and forming a frame with a central opening for exposing the central area of the base, and a removable insert sized to fit within the central opening of the frame assembly and to cover the central area of the base, wherein the frame assembly is formed separately from the base and the frame assembly comprises different materials from the base, and wherein the removable insert is removable through the central opening in the frame and replaceable.
