A method of folding a plurality of flexible elements about a central fluid storage element includes of urging an intravaginal device into a folding device; imparting relative rotation between at least a portion of the folding device and the intravaginal device; and contacting the plurality of flexible extensions with the folding device. Wherein the intravaginal device includes a fluid storage element and a plurality of flexible extensions extending therefrom, and the flexible extensions are folded about the fluid storage element in a uniform direction. Alternatively, in place of relative rotation, the flexible extensions are folded by means of guide rails of the folding device. Several apparatus may be employed in this and related methods.

Methods of packaging intravaginal device

Controlled expansion of an intravaginal device can be achieved by selectively attaching either a primary or secondary cover to the primary absorbent device having a fluid storage element. We can determine that certain portions of the tampon will expand while other portions will be restricted to substantially the compressed structure. The primary cover can be attached to the primary absorbent device either before or after the absorbent device is compressed into final tampon form. The compression may be in the axial or radial direction or a combination of both directions. The secondary cover, if used, can be attached after the tampon pledget has been compressed into the final tampon form.

Intravaginal device with controlled expansion

An intravaginal device has a fluid storage element and at least one fluid transport element in fluid communication with the fluid storage element. The at least one fluid transport element has a first plate and a second plate coupled to the first plate. The second plate is capable of separating from the first plate sufficiently to provide inter-plate capillary action. The at least one fluid transport element is bendable about an axis substantially parallel to the longitudinal axis of the fluid storage element. The invention also includes methods and apparatus useful in the production of an intravaginal device.

Intravaginal device with fluid transport plates

An intravaginal device has a fluid storage element having a longitudinal axis and is in fluid communication with at least one fluid transport element. The at least one fluid transport element has a first plate having an outwardly oriented surface and an inwardly oriented surface and a second plate coupled to the first plate. The second plate has a first surface disposed and maintained in facing relationship with the inwardly oriented surface of the first plate and an opposite surface. The second plate is capable of separating from the first plate sufficiently to provide inter-plate capillary action. The at least one fluid transport element is bendable about an axis substantially parallel to the longitudinal axis of the fluid storage element.

An intravaginal device has a fluid storage element and at least one fluid transport element in fluid communication with the fluid storage element. It is produced by providing an individual sheet of material having properties useful to move bodily fluids, attaching the individual sheet to a substantially cylindrical fluid storage element to form the at least one fluid storage element, folding the fluid storage element, and packaging the resultant device. The at least one fluid transport element is capable of extending radially away from the fluid storage element during use. The invention also includes alternative methods of forming the intravaginal device.
