Title: External axial fixator for osteosynthesis
Inventor: FACCIOLI GIOVANNI
IPC: A61B17/58
Filed: 1993-07-11
Abstract: A dynamic external axial splint for use in rehabilitating a fractured bone comprises a pair of spaced clamps (5, 6) for bone screws or bolts anchored to the respective fragments of the fractured bone. A central body (2) releasably and universally connects and locks these spaced clamps via ball-joints (7, 8) having provision for selective retention of a wide variety of angular relations, between the central body and the central axis of each of the spaced clamps. The central body comprises first (3) and second (4) end members and a third or intermediate member (19), affording on the one hand, longitudinally and adjustably fixed overlap of one end member with the intermediate member, and also affording limited resiliently snubbed and axially guided displaceability as between the intermediate member, and the other end member, thus rendereing the two end members and the respective bone-fragment anchorages clamped to the end members subject to the same axially guided and resiliently snubbed action. The axially displaceable and resilient snubbed action is selectively neutralised by single clamp adjustment (42) which converts the dynamic external splint into a fixed external splint or fixator.

Title: Biologically degradable polyester micro-particle pharmaceutical preparations injectable in bird's eggs and process for preparing thereof
Inventor: CRAFT LIBBEY SUE
IPC: A61K9/16
Filed: 1994-05-23
Abstract: A method for administering biological agents to eggs is disclosed which comprises providing the agents in a particulate carrier and injecting the carrier into the air cells of the eggs. The egg is preferably maintained in a vertical position with the air cell on top to facilitate migration of the particulate carrier between the inner and outer membranes which define the air cell, to the lower end of the egg. The particulate carrier releases the biological agent to the surrounding fluid and blood vessels. In addition, the carrier is embodied in the bird upon hatching from the egg, and therefore is available to continue to release the biological agent to the bird posthatch. Also disclosed is a composition of polyester microparticles containing bioactive polypeptide agents and methods for preparing the composition and administering bioactive agents. The composition comprises biocompatible, biodegradable microparticles having a polyester matrix and from about 5% to about 25% by weight of a biologically active, water-soluble polypeptide dispersed throughout the matrix, the polypeptide selected fom the group consisting of growth hormone releasing factor, synthetic analogs of growth hormone releasing factor, and pharmacologically active fragments thereof. The method for preparing the composition includes dissolving polyester in an organic solvent; suspending a biologically active agent in the polyester solution; emulsifying the suspension into an aqueous medium in which the agent is insoluble and evaporating the solvent from the emulsion to produce microparticles. The method for administering a bioactive agent to an organism involves suspending the microparticles in a suitable liquid and injecting the organism.
