A packaging assembly for packaging a surgical device including first and second needle assemblies at least a distal portion of which having a curved configuration including an inner package member having first and second recesses sized and shaped for receiving at least a handle portion of the first and second needle assemblies. The recesses extend inwardly from the distal end of the inner package member a distance so that the distal curved portions of the needle assemblies extend beyond the distal end of the inner package. The distal end has a height such that the curved distal portions do not contact a surface on which the inner package member rests. The assembly further includes an outer package member dimensioned to removably receive therein the inner package member and the surgical device. The outer package member has a height sufficient so that when the inner package member and surgical devices are received therein, the outer package element remains substantially clear from contact with the surgical devices. The inner package member and surgical device can be removed from the outer package member and placed on a substantially flat surface in a manner such that the surgical device retains its orientation, and the distal portions of the needle assemblies remain clear of the surface.

The invention is directed to non-invasive methods and apparatus for three-dimensional measurement of surface profile and/or volume, and analysis of surface texture for evaluation of wound repair, assessment of surgical reconstructions or treatment of hypertrophic scarring, evaluation of polymerization reactions for polymer and elastomeric curing processes, or in any industrial process requiring quantitative monitoring of surface texture and profile. Both volume and surface texture are quantitatively measured very accurately, and the apparatus and method can be used on both soft and hard surfaces according to the above objectives. The invention generally comprises an apparatus and method to image a three-dimensional surface for volumetric analysis and/or surface texture. The apparatus includes a laser source for emitting a predetermined wavelength beam which is reflected off the surface being imaged, and a laser detector or sensor positioned relative to the laser source for receiving the reflected beam to generate a first signal corresponding to the amount of laser energy reflected off the surface. The reflected beam is indicative of changes in the depth of the surface relative to the laser source, and can therefore be used to monitor changes in surface depth. Further, a sound source is provided for generating a coherent beam of sound waves which are reflected off the surface also. A sound detector positioned relative to the sound source receives reflected sound waves to generate at least a second signal corresponding to the amount of sound waves reflected off the surface, wherein the reflected sound waves are a measure of the surface texture. A control system selectively operates the laser source and sound source for generating the signals at a plurality of locations on the surface for analysis. The apparatus may be portable, and provides a quick and accurate quantitative measurement of a surface, and can be used in association with both hard and soft surfaces.

Immunization of animals with preparations containing more purified forms of glucosyltransferase (GTF) results in the presence of antibody in saliva demonstrable by functional inhibitions of enzyme activity and binding of radioactive enzyme. Serum antibody was also present. Immunized groups of animals had lower mean caries scores than comparably sham-immunized or nonimmunized control groups. Local immunization with GTF of serotype c or g of a Streptococcus mutans reduces the colonization, caries, and lesions caused by infection with S. mutans of serotype g (strain 6715) or c, or with serotype g or c, or with serotype a or g, respectively.

A system for fastening soft tissue to bone includes a bone screw having a threaded shaft and a screw head having an underside with malleable protuberances that project toward a distal end of the threaded shaft. A fixation plate is coupled with the threaded shaft. The fixation plate has a proximal face that opposes the underside of the screw head, a distal face that faces away from the underside of the screw head, an outer peripheral edge that extends between the proximal and distal faces, a central opening for receiving the threaded shaft, and protrusions spaced from one another around the outer peripheral edge that extend distally beyond the distal face of the fixation plate. The system includes an insertion tool having a handle and a tubular shaft extending distally from the handle. The tubular shaft has a proximal shaft section having an inner diameter that closely matches an outer diameter of the screw head, and a distal shaft section having an inner surface with a groove that seats the outer peripheral edge of the fixation plate for releasable retaining the fixation plate within the distal shaft section.
