Abstract: A filtered feedthrough comprises an insulator sealed in a ferrule opening. A terminal pin sealed in an insulator via hole has a first end that extends outwardly beyond an insulator device side. A filter capacitor has a square- or rectangularly-shaped dielectric supporting interleaved active and ground electrode plates. A passageway extending through the dielectric has an internal metallization. An external metallization is contacted to opposed longitudinal sides of the dielectric outer surface. The capacitor ground electrode plates extend to the opposed external metallizations. The outwardly extending terminal pin end is connected to the internal metallization in the dielectric passageway which in turn is connected to the active electrode plates. A conductive material connects the capacitor external metallization at one of the longitudinal sides to an oxide-resistant surface on the ferrule while the other external metallization is connected to an oxidized surface of the ferrule.

Abstract: The invention is a construct consisting of a fully-threaded screw with an attached locking bolt that secures the posterior pelvis in a transiliac transsacral fashion, in the setting of an unstable posterior pelvic ring fracture. One part of the implant is a cannulated screw that has two pitches of different threads, which is placed over a guidewire and secured on the opposite side with a cannulated locking bolt that affixes to the screw. Washers on either side of the implant provide compression, and cancellous threads across the length provide fixation within the sacrum and the iliac bones on either side. This invention provides added strength and stability compared to current fixation methods consisting of screws in isolation.
