Menstrual device and applicator system

1. A menstrual device comprising:

a frame having a side wall with an exterior surface and an interior surface, the side wall extends between a proximal end and a distal end, and the interior surface at least in part defines an interior cavity; and

a fluid barrier seal layer disposed on the exterior surface of the side wall, the fluid barrier seal layer attached directly to the exterior surface about at least a first end point;

wherein the menstrual device collects fluid,

wherein the menstrual device has a device length defined by a central vertical axis between the proximal end and the distal end, and

wherein the menstrual device is configurable in a compact configuration and in an expanded configuration, and in the expanded configuration the interior cavity has a volume greater than zero;

wherein the frame is configured to self-expand, and thereby cause the menstrual device to radially expand from the compact configuration to the expanded configuration in the absence of radially compressive forces;

wherein the frame comprises a medical grade foam material which has mechanical material properties that enable the frame to be either (i) elastically deformed, or (ii) elastically deformed and folded, into a compact configuration, and in the absence of applied forces holding the frame in a compact configuration, self-expand into an expanded configuration; and

wherein the menstrual device has a step-change that is an abrupt change in a widthwise or depthwise dimension between the proximal end and the distal end, wherein the cavity has a ratio of the surface area of the cavity immediately above the step-change to a surface area of the cavity immediately below the step-change of between about 18 to 1 and about 1 to 1.

2. The menstrual device according to claim 1 , wherein the distal end has an interior surface and the interior cavity is defined by the interior surface of the side wall and the interior surface of the distal end.

3. The menstrual device according to claim 2 , wherein the fluid barrier seal layer is disposed on less than all of the exterior surface of the side wall.

4. The menstrual device of claim 1 , wherein the fluid barrier seal layer comprises at least one of a molded or thermoformed polymer, a flexible film, or a hydrophobic nonwoven material.

5. The menstrual device of claim 1 , wherein the frame has a gram per gram absorbency of greater than or equal to 5 gtg as measured by a syngyna apparatus using a 1% saline solution and a flow rate of 0.8 ml/min.

6. The menstrual device of claim 1 , wherein the fluid barrier seal layer end point is peripheral.

7. The menstrual device of claim 6 , wherein the fluid barrier seal attaches to a withdrawal element.

8. The menstrual device of claim 1 , wherein the fluid barrier seal layer includes a second end point such that the first end point is closer to the proximal end and the second end point is closer to the distal end.

9. The menstrual device of claim 1 , wherein the barrier seal layer is vacuum formed onto the frame.

10. The menstrual device according to claim 1 , wherein the frame has a length of between about 1.5 inches and about 2.0 inches.

11. The menstrual device according to claim 10 , wherein the menstrual device has a cavity, wherein cavity has a diameter of greater than 0 inches and up to about 1.08 inches, and wherein the menstrual device has a length ratio defined as a length of the cavity divided by the length of the frame, wherein the length ratio is less than or equal to 1:2.

12. The menstrual device according to claim 11 , wherein the menstrual device has a ratio of an exposed surface area of the cavity to the surface area of just the proximal end of between about 2.5 to 1 and about 1 to 1.

13. A menstrual device comprising:

a frame having a side wall with an exterior surface, the side wall extends between a proximal end and a distal end; and

a fluid barrier seal layer disposed on the exterior surface of the side wall and is directly attached to the frame at least at a first point of attachment;

wherein the menstrual device collects fluid, and

wherein the menstrual device is configurable in a deployed configuration and in an at-rest configuration, the deployed configuration having a deployed footprint and the at-rest configuration having an at-rest footprint, and

wherein the deployed footprint that is up to or equal to 100% of the at-rest footprint;

wherein the frame is configured to self-expand, and thereby cause the menstrual device to radially expand from the compact configuration to the expanded configuration in the absence of radially compressive forces;

wherein the frame comprises a medical grade foam material which has mechanical material properties that enable the frame to be either (i) elastically deformed, or (ii) elastically deformed and folded, into a compact configuration, and in the absence of applied forces holding the frame in a compact configuration, self-expand into an expanded configuration; and

wherein the menstrual device has a step-change that is an abrupt change in a widthwise or depthwise dimension between the proximal end and the distal end, wherein the cavity has a ratio of the surface area of the cavity immediately above the step-change to a surface area of the cavity immediately below the step-change of between about 18 to 1 and about 1 to 1.

14. The menstrual device according to claim 13 , wherein the frame has a length of between about 1.5 inches and about 2.0 inches.

15. The menstrual device according to claim 14 , wherein the menstrual device has a cavity, wherein the cavity has a diameter of greater than 0 inches and up to about 1.08 inches, and wherein the menstrual device has a length ratio defined as a length of the cavity divided by the length of the frame, wherein the length ratio is less than or equal to 1:2.

16. The menstrual device according to claim 15 , wherein the menstrual device has a ratio of an exposed surface area of the cavity to the surface area of just the proximal end of between about 2.5 to 1 and about 1 to 1.
