Magnetic vaginal dilator
Aspects of the present invention are related to magnetic medical devices for the treatment of chronic medical conditions such as Vulvodynia, Vaginismus, Vaginal Stenosis, Vaginal Atrophy, among others. The magnetic medical device in accordance with the present invention is of a generally elongated shape having an ogive top end, a middle portion of an active diameter, and a bottom end of a passive diameter. The magnetic medical device has an array of magnets within, where the magnets generate a negative magnetic field adjacent to an external surface of the magnetic medical device.
1. A magnetic vaginal dilator comprising:
a shell component that presents a smooth outer surface having an ogive top end and an elongate cylindrical middle portion that tapers outwardly proximate to an open bottom end, the shell component having an inner surface that defines a cavity that is accessible at the open bottom end;
a substrate film having one or more magnets affixed thereto and disposed within the cavity of the shell component such that the one or more magnets extend circumferentially about the inner surface at the middle portion of the shell component; and
a cap component sized to fit into the open bottom end of the shell component and seal the substrate film within the cavity of the shell component.
2. The magnetic vaginal dilator of claim 1 , wherein the shell component and the cap component comprise a medical grade thermoplastic polymer material.
3. The magnetic vaginal dilator of claim 2 , wherein the medical grade thermoplastic polymer material comprises polycarbonate.
4. The magnetic vaginal dilator of claim 1 , wherein the one or more magnets comprise neodymium earth magnets.
5. The magnetic vaginal dilator of claim 1 , wherein the one or more magnets present a general cylindrical shape.
6. The magnetic vaginal dilator of claim 5 , wherein the one or more magnets have a diameter from 0.1 inches to 0.5 inches and a height from 0.05 and to 0.1 inches.
7. The magnetic vaginal dilator of claim 6 , wherein the one or more magnets have a diameter of 0.25 inches and a height of 0.0625 inches.
8. The magnetic vaginal dilator of claim 5 , wherein the one or more magnets have a positive polar portion and a negative polar portion, wherein the negative polar portion of the one or more magnets is directed radially inward toward the shell component when the substrate film is within the cavity of the shell component.
9. The magnetic vaginal dilator of claim 1 , wherein a diameter of the elongate cylindrical middle portion ranges between 0.5 inches and 1.5 inches.
10. The magnetic vaginal dilator of claim 1 , wherein a diameter of the bottom end ranges between 1 inch and 2 inches.
11. The magnetic vaginal dilator of claim 1 , wherein a total length of the magnetic vaginal dilator ranges between 1.5 inches and 8 inches.
12. The magnetic vaginal dilator of claim 1 , wherein the cap component is ultrasonically sealed to the shell component.
13. The magnetic vaginal dilator of claim 1 , wherein the substrate film comprises a thickness ranging between 0.002 inches to 0.008 inches.
14. The magnetic vaginal dilator of claim 13 , wherein the substrate film comprises a thermoplastic polymer material.
15. The magnetic vaginal dilator of claim 14 , wherein the thermoplastic polymer material comprises polyester.
16. The magnetic vaginal dilator of claim 1 , wherein the substrate film is rolled to form a magnetic sleeve.
17. The magnetic vaginal dilator of claim 16 , wherein the one or more magnets includes an evenly distributed array of magnets, and wherein the magnetic sleeve is configured to evenly distribute a magnetic field about at least a portion of the smooth outer surface.
18. The magnetic vaginal dilator of claim 1 , wherein the inner surface, proximate to the open bottom end, presents an internal flange, and wherein the cap component is configured to engage the internal flange when fit into the open bottom end.
19. A magnetic vaginal dilator comprising:
a shell component that presents an outer surface having an arcuate top end and an elongated cylindroid middle body that tapers radially outward proximate to an open bottom end, the open bottom end presenting a cavity defined by an inner surface of the shell component and further presenting an internal flange;
a polymer sheet having a plurality of magnets affixed thereon and rolled into a sleeve, the sleeve being disposed into the cavity of the shell component such that the plurality of magnets is coaxially positioned around the inner surface along at least a portion of the elongated cylindroid middle body; and
a cap component sized to fit into the open bottom end of the shell component and engage the internal flange to seal the polymer sheet within the cavity of the shell component.
