A device for draining cysts includes a catheter system configured to deploy an absorbent material, including but not limited to a foam, into a cyst. The absorbent material advantageously absorbs fluid contained within the cyst, for example fluid that may remain following aspiration, reducing the potential for cyst recurrence. In various embodiments, the absorbent material may be bioabsorbable, radiolucent, echogenic, drug eluting, or a combination thereof. In some embodiments the device may further include or be coupled to a vacuum source which applies negative pressure to the cyst during foam delivery, thereby reduce the overall size and/or profile of the cyst.

A light emitting composition including first color emitters and second color emitters. The first color emitters are configured to emit, upon exposure to an energy source, visible light at a target color in response to absorption of energy across a first band of wavelengths. The second color emitters are configured to emit, upon exposure to the energy source, visible light at the target color in response to absorption of energy across a second band of wavelengths. The light intensity observable at the target color is enhanced relative to reflected white light without emission from the first and second color emitters. The light emitting composition can be a part of a paint, an ink, a fabric, a thread, a road sign, a highway marking, an automobile, a boat, a plane, a reflector, a building product, a concrete product, an epoxy product, a jewelry product, colored contact lens, a candle product, a rubber product, a plastic product, or other colored surface.

A tampon applicator barrel includes an insertion tip at a forward end of the barrel, a main body section that extends from the insertion tip, and a reverse taper section that is joined to the main body section so that the main body section is between the insertion tip and the reverse taper section. The main body section tapers toward the insertion tip section. The reverse taper section tapers in a direction away from the insertion tip section. A finger grip section extends from the reverse taper section to a plunger receiving end of the barrel opposite the forward end. The barrel is straight from the forward end to the plunger receiving end that receives a plunger.
