Publication number: 20240123218Abstract: An implantable cardiac defibrillator (ICD) system includes an ICD implanted subcutaneously in a patient, a defibrillation lead having a proximal portion coupled to the ICD and a distal portion having a defibrillation electrode configured to deliver a defibrillation or cardioversion shock to a heart of the patient, and a pacing lead that includes a distal portion having one or more electrodes and a proximal portion coupled to the ICD. The distal portion of the pacing lead is implanted at least partially along a posterior side of a sternum of the patient within the anterior mediastinum. The ICD is configured to provide pacing pulses to the heart of the patient via the pacing lead and provide defibrillation shocks to the patient via the defibrillation lead. As such, the implantable cardiac system provides pacing from the substernal space for an extravascular ICD system.Type: ApplicationFiled: December 26, 2023Publication date: April 18, 2024Inventors: Amy E.

Patent number: 6647235Abstract: A replenisher for facilitating flow of toner in an electrophotographic apparatus. The replenisher includes a sump for receiving the toner. An beater element having a plurality of blades is rotatably mounted within the sump wherein some of the blades impart a shear force and a normal force along the axis of rotation to the toner while others of the blades impart a shear force and a normal force towards or away from the axis of rotation to the toner as the beater is rotated through the toner. This effectively “aerates” the toner and keeps it mobile within the sump.Type: GrantFiled: May 8, 2002Date of Patent: November 11, 2003Assignee: Heidelberger Druckmaschinen AGInventors: Kenneth M. Patterson, Paul E. Thompson, Laverne N. Lincoln, Jr., James G. Blum

Patent number: 6292957Abstract: A shower curtain retainer assembly for retaining the bottom of a shower curtain against a shower enclosure wall is described. The assembly includes a first set of plastic disks, a second set of plastic disks and a set of magnetically responsive plates. A magnet is encased in each plastic disk. The magnetically responsive plates are attached to the inside wall of the shower enclosure that is adjacent to the bottom of the shower curtain. The first set of plastic disks are positioned on the front face of the shower curtain and are aligned with the positions of the magnetically responsive plates. The second set of plates are positioned on the back face of the curtain in juxtaposition with the first set of plastic disks. The first and second sets of plastic disks are held in place by magnetic attraction forces from the magnets encased in the disks. When the shower curtain is closed, the first set of plastic disks become magnetically attached to the magnetically responsive plates.Type: GrantFiled: August 7, 2000Date of Patent: September 25, 2001Inventor: Paul E.

Patent number: 6125252Abstract: An adjustment mechanism for setting up spacing of a development station for a reproduction apparatus within a desired tolerance range such that marking particles from the development station properly develop electrostatic images. The adjustment mechanism includes a datum member and a cam having a locating post for the development station extending from the cam. The datum member includes, for example, a bracket in the reproduction apparatus, and at least one pin attached to the bracket. The cam is adjustably associated with the datum member so as to selectively position the locating post a predetermined distance from the datum member. The adjustable cam includes, for example, a member defining a plurality of spaced openings, the openings capable of receiving the at least one pin of the datum member so as to position the locating post dependent upon which opening the at least one pin is received within.Type: GrantFiled: December 22, 1998Date of Patent: September 26, 2000Inventors: Paul E.
