Releasable fluid controller and insemination device

1 . A fluid controller configured for removable attachment to a fluid introduction device, wherein the fluid controller comprises:

a body configured to extend at least partially over the fluid introduction device;

an orifice arranged relative to the body to facilitate transfer of a fluid from the fluid introduction device through the fluid controller;

a fluid retention structure extending outwardly from at least a portion of the body, wherein the fluid retention structure is configured to engage with a wall of a body cavity and inhibit a flow of the fluid from the body cavity, wherein the fluid retention structure is configured such that attachment of the fluid controller to the fluid introduction device causes a reduction in at least one dimension associated with the fluid retention structure; and

at least one connector configured to releasably attach the fluid controller to the fluid introduction device.

2 . The fluid controller of claim 1 , wherein the at least one dimension includes a radial dimension.

3 . The fluid controller of claim 1 , wherein the at least one connector is further configured such that the fluid controller can be detached from the fluid introduction device after insertion into the body cavity and the fluid introduction device can be removed from the body cavity without removal of the fluid controller from the body cavity.

4 . The fluid controller of claim 1 , wherein the fluid retention structure is configured to expand in at least one dimension upon detachment of the fluid controller from the fluid introduction device.

5 . The fluid controller of claim 1 , wherein the fluid retention structure is configured to engage with the wall of the body cavity and retain the fluid controller at least partially within the body cavity after the fluid introduction device is detached from the fluid controller and removed from the body of the fluid controller.

6 . The fluid controller of claim 1 , wherein the orifice is a single slit and the orifice is configured to open wider when the fluid controller is attached to the fluid introduction device than when the fluid controller is not attached to the fluid introduction device, and wherein the orifice is configured to open wider when the at least one connector is in tension.

7 . The fluid controller of claim 1 , wherein the fluid introduction device comprises a plunger-based device.

8 . The fluid controller of claim 1 , wherein the at least one connector comprises a ring-shape connector configured to slip over a corresponding protrusion associated with the fluid introduction device.

9 . The fluid controller of claim 1 , wherein at least a portion of the fluid controller comprises one or more of a thermally, pH, and moisture responsive material configured to change shape or color when at least partially within the body cavity.

10 . A kit for aiding conception, the kit comprising:

a fluid introduction device; and

a fluid controller configured for removable attachment to the fluid introduction device, wherein the fluid controller comprises:

a body configured to extend at least partially over the fluid introduction device;

an orifice arranged relative to the body to facilitate transfer of a fluid from the fluid introduction device through the fluid controller;

a fluid retention structure extending outwardly from at least a portion of the body, wherein the fluid retention structure is configured to engage with a wall of a vaginal canal and inhibit a flow of the fluid from the vaginal canal, wherein the fluid retention structure is configured such that attachment of the fluid controller to the fluid introduction device causes a reduction in at least one dimension associated with the fluid retention structure; and

at least one connector configured to releasably attach the fluid controller to the fluid introduction device.

11 . The kit of claim 10 , further including a cup, wherein the cup is configured for collecting the fluid, and the fluid introduction device is configured for drawing the fluid from the cup.

12 . The kit of claim 10 , wherein the at least one dimension includes a radial dimension.

13 . The kit of claim 10 , wherein the at least one connector is further configured such that the fluid controller can be detached from the fluid introduction device after insertion into the vaginal canal and the fluid introduction device can be removed from the vaginal canal without removal of the fluid controller from the vaginal canal.

14 . The kit of claim 10 , wherein the fluid retention structure is configured to expand in at least one dimension upon detachment of the fluid controller from the fluid introduction device.

15 . The kit of claim 10 , wherein the fluid retention structure is configured to engage with the wall of the vaginal canal and retain the fluid controller at least partially within the vaginal canal after the fluid introduction device is detached from the fluid controller and removed from the body of the fluid controller.

16 . The kit of claim 10 , wherein the orifice is a single slit and the orifice is configured to open wider when the fluid controller is attached to the fluid introduction device than when the fluid controller is not attached to the fluid introduction device, and wherein the orifice is configured to open wider when the at least one connector is in tension.

17 . The kit of claim 10 , wherein a head of the fluid controller is configured to be placed over a fluid depositing end of the fluid introduction device.

18 . The kit of claim 10 , wherein the fluid introduction device comprises a syringe.
