Relates to devices for administering a substance such as a drug or chemical or the like
First Claim
1. A device for insertion into a body cavity of an animal, when in one configuration and to lie against walls of said body cavity in a second expanded configuration, said device comprising a set of interconnected primary elements, and a set of secondary elements forming connectors between said primary elements and connecting said primary elements in the form of a coil, wherein elements of at least one of said sets are constructed of a bio-degradable material.

Abstract
The device for insertion into a body cavity e.g. the rumen of an animal for example a cattle beast is in the form of a resilient helical coil with bio-degradable portions. The device is deformable to have a smaller dimension to enable insertion through a body passage into the animal cavity. The device carries a drug e.g. progesterone and is retained in the body cavity for a time during which the drug is active. After time has passed the device is broken up by bio-degrading activity into pieces small enough to be discharged naturally by the animal. An applicator is provided.

- 11. A device for insertion into a body cavity of an animal to release a desired substance therein over time, said device being in the form of a helical coil at least parts of which are resilient, said helical coil at least partly including a desired substance in a form adapted to be released from said device over time, said helical coil being resiliently extendible into a first configuration having dimensions small enough so that said helical coil is able to be passed through body passages of said animal into the desired body cavity, and being resiliently biased towards a second expanded configuration retaining its helical form whereby the coil expands until said coil presses against the inner lining of said body cavity in order to be retained within the body cavity.
