Abstract

An applicator for delivering pharmaceutical products or the like to a bodily cavity includes a barrel member having a distal end which is equipped with an opening. The applicator also includes a plurality of petals extending outwardly from the distal end in a generally axial direction. The petals cooperate with the opening so as to form a receptacle for releasably receiving a pharmaceutical product in the distal end of the barrel member. Each of the petals has a truncated flexible tip sized and shaped so as to engage a substantially central portion of the pharmaceutical product such that a large section of the pharmaceutical product extends outwardly beyond the petals so as to facilitate the release of the pharmaceutical product from the receptacle. The device also includes a plunger member for releasing the pharmaceutical product from the receptacle. In accordance with the present invention, the device can be packaged in a package together with the pharmaceutical product received in the receptacle.

Claims

1. An assembly comprising a pharmaceutical product;

and a device for delivering said pharmaceutical product to a bodily cavity, said device including a barrel member having a distal end, which includes an opening, a proximal end, which is positioned opposite said distal end, said barrel member being tapered as said barrel member extends from said proximal end to said distal end, and a plurality of petals extending outwardly from said distal end in a generally axial direction, said petals cooperating with said opening so as to form a receptacle in said distal end of said barrel member for releasably receiving said pharmaceutical product, each of said petals including a base connected to said distal end of said barrel member and terminating at a truncated flexible tip, each of said petals including an intermediate section extending between a corresponding one of said bases and a corresponding one of said tips, each of said petals being sized and shaped such that the entire portion of each of said intermediate sections is spaced from said pharmaceutical product in a radially outward direction and such that only said tips engage said pharmaceutical product at a substantially central portion thereof when said pharmaceutical product is fully received in said receptacle, whereby a large section of the pharmaceutical product extends outwardly beyond said petals so as to facilitate the release of said pharmaceutical product from said receptacle.

2. The assembly of claim 1, wherein said distal and proximal ends have first and second radii, respectively, said first radius being less than said second radius.

3. The assembly of claim 1, further comprising a plunger member having a distal end and a contact platform attached to said distal end of said plunger member for applying an axial force to said pharmaceutical product received in said receptacle.

4. The assembly of claim 3, wherein said plunger member is axially movable relative to said barrel member between a first position, in which said contact platform is retracted into said receptacle so as to permit the loading of said pharmaceutical product in said receptacle, and a second position, in which said contact platform is positioned adjacent said tips so as to expel said pharmaceutical product from said receptacle.

5. The assembly of claim 4, wherein when said barrel member is positioned in its said first position, said contact platform is positioned in said receptacle and is in contact with said pharmaceutical product received in said receptacle so as to properly orient said pharmaceutical product such that said distal end of said barrel member is in contact with said pharmaceutical product only at said tips.

6. The assembly of claim 5, wherein said contact platform is in engagement with said petals so as to flex said petals in a radially outward direction, when said plunger member is positioned in its said second position.

7. The assembly of claim 5, further comprising first restricting means for restricting said plunger member from moving beyond its said first position.

8. The assembly of claim 7, further comprising second restricting means for restricting said plunger member from moving beyond its said second position.

9. The assembly of claim 8, wherein said first restricting means includes an annular rib extending radially inwardly from an annular wall of said barrel member into said passageway and positioned adjacent a proximal end of said barrel member, said first restricting means having a stop member formed on said plunger member and sized and shaped so as to engage said annular rib.
