20120253407 | BONE FIXTURE ASSEMBLY - An assembly for rigid bone fixation includes a plate and a screw. The screw can be rotated freely within the plate in a non-locking configuration to secure the plate against the bone. A locking mechanism is engaged to prevent the screw from moving relative the plate. In one embodiment, the plate includes a threaded portion and a non-threaded portion. The screw head rotates within the non-threaded portion to tighten the screw and pull the plate against the bone. The locking mechanism can include a moveable nut that rotates within the threaded portion of the plate to lock the screw and plate in a locking mode. The locking mechanism can include a second screw to actuate and expansion portion of screw inserted into the bone. The assembly can be used for rigid fixation of bones that experience cyclic loads, such as the sternum and mandible. Methods of rigid bone fixation are also described. | 10-04-2012 |

20150245838 | Bushing Arm Deformation Mechanism - A medical device includes (a) a capsule including a lumen extending therethrough, a proximal end of the capsule including at least one window extending therethrough; (b) a bushing including a channel extending therethrough, a distal end including at least one arm extending distally therefrom such that a corresponding one of the arms is releasably engagable with a corresponding one of the windows; and (c) a core member including a locking portion and at least one engaging element. The locking portion is sized and shaped to be received within the channel of the bushing to apply a pressure to the arm such that the arm engages the windows. The engaging element extends laterally outward from a portion of the core member such that the engaging element engages a corresponding one of the arms to deform the arms radially inward and out of engagement with the windows. | 09-03-2015 |

20150272760 | Apparatuses For Manipulating Medical Devices And Related Methods For Use - Apparatuses for manipulating a collapsible medical device include a sheath, a first shaft including a first grasping member and a second grasping member. The second grasping member is separated from the first grasping member by a distance. The collapsible medical device may be manipulated by actuating the first grasping member and the second grasping member and by increasing the distance between the first grasping member and the second grasping member. Methods of using the apparatuses are provided. | 10-01-2015 |
20150335321 | DEPLOYMENT SYSTEM INCORPORATING APPLICATION OF ADHESIVE - The present disclosure is directed to a delivery catheter with a mechanism of discharging an adhesive during and/or immediately prior to deployment of the medical device by the delivery catheter. | 11-26-2015 |
20150342760 | ANTI-MIGRATION STENT - Embodiments of the disclosure relate to devices, systems and methods of use and manufacture. One such device is a stent. The stent includes a stent body and a coating over at least a portion of the stent body. The coating includes a shape memory polymer having an outer surface. The outer surface defines a first configuration and a second configuration. In the first configuration the outer surface is smooth. In the second configuration, the outer surface includes a micro pattern. | 12-03-2015 |
