Publication number: 20080319380Abstract: The present invention overcomes the difficulties in the sterilization and delivery of viscous, multi-component compositions that require pre-mixing prior to usage by disclosing a sterile, multi-component, ready-to-use product wherein each component is sterilized independently and then assembled into a sterilized delivery kit. In certain preferred embodiments of the present invention, a sterile, polymerizable system is provided that comprises a plurality of sterile polymerizable monomers, said monomers having been sterilized by passing them through a filter; at least one sterile filler which has been exposed to conditions effective to render said filler sterile, and the sterile monomers and the sterile filler being blended together to form at least one substantially homogeneous blend contained within a sterile delivery vessel.Type: ApplicationFiled: September 5, 2008Publication date: December 25, 2008Applicant: Vita Special Purpose CorporationInventors: Vasanth Prabhu, Jeffrey J. Wicklund, Erik M. Erbe, Anthony M. Wilkes

Publication number: 20060039951Abstract: Shaped, preferably porous, inorganic bodies are provided which are prepared from a reactive blend. In accordance with one preferred embodiment, the solution is absorbed into a porous sacrificial substrate such as a cellulose sponge. The solution-saturated substrate is heated and an oxidation-reduction reaction occurs thereby forming an inorganic solid. A shaped, inorganic body is formed in situ. Optional, but preferred additional thermal treatment of the shaped, inorganic body removes the organic substrate, leaving an inorganic body that faithfully mimics the porosity, shape, and other physical characteristics of the organic substrate. Inorganic substrates may also be used to good effect. Large varieties of shaped bodies can be prepared in accordance with other embodiments of the invention and such shapes find wide use in surgery, laboratory and industrial processes and otherwise. The invention also provides chemically and morphologically uniform powders, including those having uniformly small sizes.Type: ApplicationFiled: May 24, 2005Publication date: February 23, 2006Applicant: Vita Special Purpose CorporationInventors: Ronald Sapieszko, David Dychala, Erik Erbe

Patent number: 6969501Abstract: Uniformly sized and shaped particles of metal salts are provided comprised of one or more metal cations in combination with one or more simple oxoacid anions and a general method for the controlled precipitation of said metal salts from aqueous solutions. The methods proceed via the in situ homogeneous production of simple or complex oxoacid anions in which one or more of the nonmetallic elements e.g. Group 5B and 6B (chalcogenides), and 7B (halides) comprising the first oxoacid anion undergo oxidation to generate the precipitant anionic species along with concurrent reduction of the nonmetallic element of a second, dissimilar oxoacid anion. The oxoacid anions are initially present in solution with one or more metal cations known to form insoluble salts with the precipitant anion.Type: GrantFiled: October 3, 2001Date of Patent: November 29, 2005Assignee: Vita Special Purpose CorporationInventors: Ronald S. Sapieszko, Erik M. Erbe
