  • Osmotic system for delivery of fluid-sensitive somatotropins to bovine animals
    Patent number: 5980509
    Abstract: A delivery system is disclosed for delivering a fluid-sensitive beneficial agent such as a somatotropin, or an analogue or derivative thereof, to an animal such as a bovine. The delivery system comprises a wall that surrounds an internal compartment, said wall comprising a first wall section that limits the passage of fluid into the system and a second wall section that permits the passage of fluid into the system. The wall may further comprise an end cap which may be adapted for ultrasonic welding to the first wall section and may maintain the beneficial agent in contact with an exit. The compartment comprises a beneficial agent and an expandable driving member. The delivery system comprises an exit for delivering the beneficial agent to the animal.

  • Implantable system for delivery of fluid-sensitive agents to animals
    Patent number: 5871770
    Abstract: A delivery system (10) is disclosed for delivering a fluid-sensitive beneficial agent (7) such as a somatotropin, or an analogue or derivative thereof, to an animal such as a bovine. The delivery system comprises a wall that surrounds an internal compartment, said wall comprising a first wall section that limits the passage of fluid into the system and a second wall section that permits the passage of fluid into the system. An exit passageway is provided for delivering the beneficial agent an interior compartment (18) to the animal. The exit passageway is sealed with a wax seal (30) which is expelled through the passageway (13) as the internal pressure within the device (10) reaches a predetermined "bursting" pressure.
