20090143830 | MOLDABLE PASTE COMPOSITION - The invention concerns a novel moldable and/or flowable composition for application to a bone defect site to promote new bone growth at the site. The composition includes a therapeutic material and a carrier comprising means for achieving reverse phase characteristics. In one embodiment, the therapeutic material can be a resorbable alloplastic material and the carrier can be a poloxamer. In a specific embodiment, the resorbable alloplastic material is a biphasic material composed of hydroxyapatite and tricalcium phosphate (HA-TCP), and the carrier is poloxamer 407 (Pluronic® F127). The invention further includes methods for using the novel composition. | 06-04-2009 |
20100087625 | METHOD OF ENHANCING RECOMBINANT PROTEIN PRODUCTION - The present invention provides a method of enhanced protein production that comprises the step of expressing a recombinant gene encoding the protein in eukaryotic cells under conditions in which cleavage of the pro-domain of the protein is inhibited or eliminated. Generally the method of the present invention includes the step of inhibiting or altering the cleavage of a pro-domain of a recombinant protein of interest in order to increase the amount of recombinant protein secreted from a eukaryotic cell. Recombinant proteins that can be prepared using the method of this invention include members of the transforming growth factor-β (TGF-β) superfamily, such as bone morphogenetic proteins. Also provided are genetically engineered cells and polynucleotides for performing the method of the invention. | 04-08-2010 |
20110172671 | Orthopedic/Spine Bone Mill - A orthopedic/spine bone mill comprising a vessel and a rotatable grinding tool to produce ground autologous and or allograft bone particles for surgical bone reconstruction use, wherein the vessel includes a wall defining a circular cylindrical chamber having a concentric axis. The vessel further includes generally concave or a cup shaped bottom wall which corresponds to the shape of the cutting blade and a lid adapted to be removably connected to the vessel. The lid includes an opening coincident with the axis. The grinding tool includes an elongated shaft extending through the opening in the Jid along the axis with a cutting blade mounted to the shaft within the chamber whereby the cutting blade can be rotated by motive device, such as a drill find in the operating room, engaging the shaft exterior of the vessel to cut bone, placed in the vessel, into said bone particles. | 07-14-2011 |
20140100161 | System and Method for Multiphasic Release of Growth Factors - A system for multiphasic delivery of at least one growth factor at a treatment site comprises a delivery vehicle for releasing at least one growth factor in an initial release profile and a carrier for releasing at least one growth factor in a sustained release profile. The initial release profile releases at least one growth factor over a period of hours to days, wherein the growth factor is released in a large amount initially, with the remainder being released in progressively lower amounts. The sustained release profile releases at least one growth factor over a period of days to weeks, wherein the growth factor is released at a generally constant amount over such period. The system of the invention is particularly suited for applications on bioimplants. The invention also comprises methods and kits for multiphasic delivery of at least one growth factor. | 04-10-2014 |
