Intrauterine medicator

Claim 3

A device as defined in claim 1 wherein said solid substance is an antifertility agent.

Claim 4

A device as defined in claim 1 wherein said antifertility agent is progesterone.

Claim 5

A device as in claim 1 wherein said biologically active substance is in the form of pellets.

Claim 6

A device as defined in claim 1 wherein said retaining means comprises, a pair of spring members mounted on said container, each of said spring members having a first end portion fixed to said container and an angularly related second end portion adapted to engage the uterine walls.

Claim 7

A device as defined in claim 1 wherein said retaining means comprises a first transverse arm and a second arm coplanar with said first arm and dependent therefrom, said second arm including said container.

Claim 8

An intrauterine medicator device for the controlled release of biologically active materials, said device comprising a container for said materials adaptablE to containment within the uterine cavity and having an elongated generally cylindrical side wall and opposed end wall members, said side wall having a plurality of perforations therein, a column of biologically active material retained within said container and adapted to be released through said perforations into the uterus, means within said container for urging said material towards said perforations and maintaining a supply thereof adjacent said perforations, and resilient retaining means affixed to an external wall of said container for retaining said device within the uterine cavity.

Claim 9

An intrauterine medicator device for the controlled release of biologically active materials, said device comprising a container for said materials adaptablE to containment within the uterine cavity and having an elongated generally cylindrical side wall and opposed end wall members, said side wall having a plurality of perforations therein, a column of biologically active material retained within said container and adapted to be released through said perforations into the uterus, means within said container for urging said material towards said perforations and maintaining a supply thereof adjacent said perforations, and resilient retaining means affixed to an external wall of said container for retaining said device within the uterine cavity.

Claim 10

A device as defined in claim 7 wherein said perforations are formed in said side wall at locations substantially intermediate said end walls, and said means for urging said material towards said perforations comprises a compression spring positioned within said container at each end thereof for bearing engagement with its associated end wall and the opposed end of said column whereby the central portion of said column is maintained adjacent said perforations during release of said material.

Claim 11

A device as defined in claim 7 wherein said perforations are formed in said side wall at one end thereof, and said means for urging said material towards said perforations comprises a compression spring positioned within said container in bearing relation between the other of said end walls and one end of said column to maintain the other end of said column adjacent said perforations and against said one wall during release of said biologically active material.

Claim 12

An intrauterine medicator device comprising, in combination, a generally cylindrical tube having closed end portions and formed of an inert material, said tube having a plurality of perforations adjacent one end portion thereof, a column of individual pellets of biologically active material contained within said tube, a compression spring positioned in said tube in bearing relation between the other end portion of said tube and one end of said column to urge said column towards said one end and to continuously maintain a portion of said column adjacent said perforations, a pair of spring members mounted on said container, each of said spring members having a first end portion fixed on said container and extending parallel to the longitudinal axis thereof and a second end portion diverging at an acute angle from said first portion adapted to engage the uterine walls to retain said device in the uterus, whereby body fluids leach said biologically active material through said perforations for local application to said uterine walls.

Claim 13

An intrauterine medicator device comprising, in combination, a generally cylindrical tube having closed end portions and formed of an inert material, said tube having a plurality of perforations adjacent one end portion thereof, a column of individual pellets of biologically active material contained within said tube, a compression spring positioned in said tube in bearing relation between the other end portion of said tube and one end of said column to urge said column towards said one end and to continuously maintain a portion of said column adjacent said perforations, a pair of spring members mounted on said container, each of said spring members having a first end portion fixed on said container and extending parallel to the longitudinal axis thereof and a second end portion diverging at an acute angle from said first portion adapted to engage the uterine walls to retain said device in the uterus, whereby body fluids leach said biologically active material through said perforations for local application to said uterine walls.

Claim 14

A device as defined in claim 10 wherein said second end portions of said spring members lie in parallel planes, tangent to said tube and extend in generally opposite directions whereby said spring members form an inverted V-shaped retaining means.

Claim 15

A device as defined in claim 11 including, a bearing pad positioned between said compression spring and one end of said column.
