Patent number: 7722632Abstract: A device for holding a surgical suture including a base, a guide body, a cam body, a bearing member, and a spring member. The base has a top side, a front edge, and a back edge. The guide body projects from the top side of the base and defines a guide face having an entrance side and an exit side. The entrance side is adjacent the front edge and the exit side is adjacent the back edge. The cam body is pivotally mounted to the top side and forms a toothed surface positioned to selectively secure a surgical suture against the guide face. The spring member is positioned between the cam body and the bearing member, biasing the toothed surface toward the guide face.Type: GrantFiled: May 9, 2003Date of Patent: May 25, 2010Assignee: Medtronic, Inc.Inventors: Paul T.

Patent number: 7589956Abstract: A sealed electrode enclosed in separator material is provided for use in a capacitor cell. The separator may either be adhered to the electrode in sheets, or may be formed into a pouch, which is used to enclose the electrode. A method of preparing the electrode sealed with separator is described in which an adhesive is used to secure the pouch to the electrode before sealing it. The prefabricated electrode and separator combination may be used in both coiled capacitor cells and flat capacitor cells that are often used in implantable medical devices. Electrodes prepared in this fashion can be efficiently and reliably aligned within the case of a capacitor cell, and have no exposed electrode surfaces that could lead to short-circuiting within the cell.Type: GrantFiled: February 9, 2006Date of Patent: September 15, 2009Assignee: Medtronic, Inc.Inventors: John D. Norton, Anthony W. Rorvick, Mark D. Breyen, Paul A. Pignato, Thomas P. Miltich
