Abstract
An intraruminal device is provided for the time release dispensation of a medicament to a ruminant. The device has no metal parts which may damage slaughterhouse equipment or injure a human upon consumption of ground meat from a ruminant from which the device was not properly removed. The device may use a nonmetallic bladder assembly having a to supply a compressive force to the medicament matrix to keep the matrix abutted against the first end of the device. The device may also use a piston to create a fluid-tight seal allowing part of the device to be pressurized, allowing the piston to provide a compressive force to the medicament matrix. The matrix surface at the first end is exposed to ruminal juices for dissolution of the matrix and dispensation of the medicament into the rumen.
