Title: Transmucosal delivery of macromolecular drugs
Inventor: HEIBER SONIA J
IPC: A61K9/00
Filed: 1994-02-03
Granted: 2005-05-03
Abstract: A method and system for mucosally administering a macromolecular drug to the mucosa of the oral cavity is shown. The system comprises an inner drug/enhancer/polymer layer (11) having one surface adapted to contact and adhere to the mucosal tissue of the oral cavity and an opposing surface in contact with and adhering to an overlying inert layer (12). The inner layer (11) contains from about two to sixty percent by weight of a bile salt enhancer, five to sixty five percent by weight of a hydrophilic polymer which is water soluble or swellable and an effective amount of a macromolecular drug having a molecular weight of at least 500 daltons.  Polysaccharides, polypeptides and proteins are preferred forms of macromolecular drugs. The bile salt enhancer facilitates the delivery of macromolecules such as low molecular weight heparin and calcitonin. The polymer serves as a plasticizer to prevent the crystallization and/or aggregation of such macromolecular drugs. Hydroxypropyl cellulose is a particularly suitable polymer.

Title: Animal ear tag mounting mechanism
Inventor: HICKS DONALD D
IPC: A01K11/00
Filed: 1995-12-28
Granted: 2006-07-18
Abstract: A snug fitting two-piece tagging system which employs a low-grade spring function therein. The present invention provides a piercing stud coupled to a domed shaped member. The compressible domed shaped member may have an outer surface which is domed away from the piercing stud and is concavely rounded on the inner surface from which the stud emanates. Further, the compressible domed shaped piercing stud may be formed from a flexible material. In this configuration, the compressible domed shape piercing stud functions as a low-grade spring which may be slightly compressed upon installation. That is, the piercing stud base may be snug against the tagged material around the contacting perimeter, leaving no gap to snag a foreign object. Another embodiment of the present invention allows for interruption of contact around the contacting perimeter of the compressible domed shaped member to prevent the entrapment of moisture or the like in and around the compressible domed shaped member. This embodiment may prevent necrosis under the tag element while providing the attendant advantages of the spring action discussed above.

A transducer (45) of the microactuator (32) is preferably a circular disk, 2 to 8 mils thick, of stress-biased PLZT. Such disks can be mounted as drumheads, preferably in conjunction with a flexible diaphragm (53, 56, 57), to a threaded metal tube (46), e.g. 1.4 mm in diameter and 2.0 mm long. The tube (46) is implanted into a fenestration in the promontory (18) of a subject's inner ear (17). Securing the disk-shaped transducer (45) to a tube (46) having a diameter larger than the fenestration and filling the tube (46) with fluid (58) provides hydraulic amplification for the transducer's displacement. The microphone (28) is preferably fabricated from a thin sheet of PVDF overcoated with inert metal electrodes (42a, 42b).
