Autonomously administering a pharmaceutical agent to an animal. A tag assembly is affixed to an animal. The tag assembly may be an ear tag, although other configurations can be used. The tag assembly has a reservoir that houses a pharmaceutical agent. An actuator and an application mechanism are provided. A control signal is generated responsive to an input, which may be from a sensor associated with the tag assembly or may be from an external circuit located apart from the tag assembly. Receipt of the control signal causes the actuator to apply a force to the reservoir, which in turn induces a flow of the pharmaceutical agent, via the application mechanism, to a body of the animal. The pharmaceutical agent may be topically or intravenously applied. The pharmaceutical may be an insecticide or some other agent. Multiple reservoirs can be provided to dispense the same or different pharmaceutical agents.

An implant injection device, includes an injection needle, a receiver housing for receiving at least one implant, injection device, including a pushing rod, arranged upstream from the implant housed in the receiver housing, and configured to push the implant through the injection needle between an initial position and a final position, a pushing member for pushing the pushing rod between the initial position and the final position, a retaining member for retaining the pushing rod by friction relative to the injection needle, opposing the displacement of the pushing rod to its final position, it being possible for a user to actuate the retaining member.

A device for inserting a marker into tissue at a biopsy site including an elongate shaft that moves conjointly with a plunger, and a spring secured to the distal end of the shaft. The device may comprise a cannula configured to receive a distal end of the shaft, and with a crimp, dimples, or other features formed near the shaft's distal end. The cannula may comprise a lateral aperture where a marker may be ejected from the lumen thereof. A ramp portion may be formed in communication with the lateral aperture, and the ramp portion may comprise a preselected slope that controls the angle at which the marker is ejected.

An ear tagging station includes a cart or table having at least one tagging pliers mounted thereon. The pliers have jaws which are normally open to receive male and female tag parts. An actuating arm engages one of the plier handles. A foot pedal on the cart is depressed to lift the arm and thereby close the plier jaws so as to secure the ear tag to a piglet's ear.

In the specification and drawings a method and apparatus for delivering a drug into a nasal turbinate or nasal polyp is described and shown, which can include implanting a drug eluting implant into a nasal turbinate or nasal polyp; and leaving the drug eluting material in the nasal turbinate or nasal polyp for at least one day such that a drug is released from the drug eluting implant over a period of time.

A marker deployment tool may comprise a marker cannula having a lateral deployment aperture, a push rod slidably disposed within the marker cannula and a scalloped tip coupled to the distal end of the marker cannula. The scalloped tip may have a push rod recess configured to receive a portion of the distal end of the push rod such that the push rod does not appreciably extend out of the lateral deployment aperture when the push rod is actuated distally. The marker deployment tool may further comprise a magnet at or near the distal end. This magnet may be used in combination with a magnet or plurality of magnets disposed about an access chamber in a tissue sample holder to assist the user in aligning the marker deployment tool. The access chamber in the tissue sample holder may also include a valve, two valves, or a removable plug.

Embodiments herein describe tools, instruments and methods for aseptic loading, dispensing and/or delivering cells into an implantable device and aseptically and selectively sealing a device inside a sterile package as well as and storing and preparing for shipment the cell-filled device.

A magnetic marker for use in locating tissue for surgery includes a casing and two to five magnetic elements arranged in a row. The two or more magnetic elements are separated from each other by an isolating material. The magnetic marker may be non-bio-absorbable. This means that the magnetic marker is invariable as it does not decay over time. This invariability ensures that on the basis of the signal measured by a magnetometer device a distance between a probe of the magnetometer device and the magnetic marker can be determined.
