20130225426 | REACTIVITY-DEPENDENT AND INTERACTION-DEPENDENT PCR - Methods, reagents, compositions, and kits for reactivity-dependent polymerase chain reaction (RD-PCR) and interaction-dependent polymerase chain reaction (ID-PCR) are provided herein. RD-PCR is a technique useful for determining whether a reactive moiety can form a covalent bond to a target reactive moiety, for example, in screening a library of candidate reactive moieties for reactivity with a target reactive moiety, and in identifying an enzyme substrate, for example, in protease substrate profiling. ID-PCR is a technique useful for determining whether a ligand can non-covalently bind to a target molecule, for example, in screening a library of candidate ligands for non-covalent interaction with a target molecule. RD-PCR and ID-PCR are also useful in detecting the presence of an analyte or an environmental condition. | 08-29-2013 |

20140345837 | HEAT EXCHANGER DISTRIBUTION ASSEMBLY AND METHOD - A heat exchanger distribution assembly includes a channel guide comprising an outer surface. Also included is an outer shell comprising a hollow portion and a plurality of distribution holes, wherein the channel guide is at least partially disposed within the hollow portion. Further included is a plurality of channel grooves disposed between an inner surface of the outer shell and the outer surface of the channel guide, wherein the plurality of channel grooves are configured to convert circumferentially spaced flow passages to axially spaced flow passages to route the fluid to a plurality of layers of a heat exchanger. | 11-27-2014 |

20120245640 | POLYAXIAL PEDICLE SCREW AND FIXATION SYSTEM KIT COMPRISING THE SCREW - A polyaxial pedicle screw may include a receiving head having a transversal U-shaped passage, and a shank having a threaded portion external to the receiving head, and a bulging end rotatable housed within the receiving head. The polyaxial pedicle screw may include a locking insert housed within the receiving head and matable with the bulging end, for locking it into position, and a set-screw engaged in the distal aperture for locking a connecting rod received within the transversal U-shaped passage. The receiving head of the polyaxial screw may include a lateral aperture, the lateral aperture exposing a contact surface of the locking insert in such a way that external pressing component can act on the contact surface to maintain the locking insert into its locking position. | 09-27-2012 |
20120277810 | INSTRUMENT FOR POSITIONING AN INTERVERTEBRAL IMPLANT FOR THE FUSION BETWEEN TWO VERTEBRAL BODIES OF A VERTEBRAL COLUMN - An instrument positions an intervertebral implant for the fusion between two vertebral bodies of a vertebral column. The instrument may include a handle having a proximal and a distal end, a locking shaft extended from the distal end of the handle, and a grasping head at the distal end of the shaft. The locking shaft may be cannulated, and a stem may be hosted inside the cannulated shaft passing through the handle. The stem may be free to rotate with respect to the locking shaft, or vice versa, while the grasping head may be formed at the distal end of the stem with a couple of prongs or clamps toward the other according to an angular relative rotation of the stem with respect to the locking shaft. The instrument may allow the surgeon to grip a corresponding implant with a simple rotation movement of his hand. | 11-01-2012 |
20120277869 | INTERVERTEBRAL IMPLANT FOR THE FUSION BETWEEN TWO VERTEBRAL BODIES OF A VERTEBRAL COLUMN AND CORRESPONDING POSITIONING INSTRUMENT - An intervertebral implant for the fusion between two vertebral bodies of a vertebral column may include a body having two opposite surfaces and holes or cavities for filling purposes during bone growth, and an engagement portion for receiving a gripping end of a positioning instrument. The engagement portion may be shaped as a splined shaft accessible through an opening of the body. | 11-01-2012 |
