Intravaginal devices containing progesterone for estrus synchronization and related processes

#The present invention generally relates to devices and processes for estrus synchronization in an organism.

#Beef Cattle

#The productive cycle of a breeding cow can be divided in three periods:

#FIG. 1 illustrates a top view of an embodiment of the intravaginal device that is the object of the present invention.

#FIG. 2 illustrates a partially cut longitudinal front view of the device of FIG. 1.

#FIG. 3 shows a cross-section view through line A—A of FIG. 1

#According to the illustration included in the drawings, specially with reference to FIG. 1, embodiments of a device of the present invention include an irregular and hollow cruciform piece (1), which can be made of vulcanized silicone, delimited by a longitudinal branch (2) consisting of a middle portion (3) that extends up and down in opposing portions, such as opposite, (3a) and (3b) mismatched between themselves according to a longitudinal shaft and extending themselves from the middle section (3) and from the intersection areas with said opposing portions (3a) and (3b). In various embodiments, branches (4) and (4′) extend from about the intersection of middle portion (3) and the first opposing portion (3a) and/or the second opposing portion (3b). Branches (4) and (4′) generally extend from middle portion (3) at an angle from about 0 degrees to about 180 degrees from respective intersection. In various embodiments, branches (4) and (4′) are provided with transversal cuts (4a) and (4b) about the intersection of the respective portions and branches.

#However portions (3a) and (3b) may oppose one another at any angle desired. Generally, all that is required is that portions (3a) and (3b) extend away from a middle portion (3). In certain embodiments, middle portion (3) will be the intersection of portions (3a) and (3b).

#Likewise, branches (4) and (4′) may extend at any angle away from middle portion (3). As well, in various embodiments, branches (4) and (4′) extend away from one another in other than a parallel orientation. In certain embodiments, middle portion (3) is the intersection of branches (4) and (4′).
