Publication number: 20180153615Abstract: Medical devices are described for performing mapping, ablating, and/or pacing procedures on one or more layers of the cardiac wall via an epicardial approach in a minimally invasive (e.g., orthoscopic) surgical procedure. One of the medical devices described includes a main support member and one or more secondary support members extending outwardly from the main support member having electrodes configured to receive electrical impulses. The secondary support member may include a support pad configured to be removably attached to a corresponding area of the epicardium for holding the medical device in place during a procedure, such as through application of vacuum pressure via a containment dome provided on each secondary support member. Further, an ablating electrode may be slidably disposed along the main support member for transmitting energy to a target site proximate the electrode. Associated methods are also described.Type: ApplicationFiled: January 5, 2018Publication date: June 7, 2018Inventors: Jeko Metodiev Madjarov, John Michael Fedor, Jackie H. Kasell

Patent number: 9527578Abstract: One aspect of the present invention provides a propeller for an aircraft. The propeller comprises a propeller hub, a spinner for streamlining the propeller and a plurality of composite propeller blades mounted to the propeller hub. The propeller blades are arranged to rotate together in the same rotational direction in at least two parallel planes substantially perpendicular to an axis of rotation of the propeller. The propeller has a reduced sized spinner with an improved aerodynamic profile that can be better matched to an engine nacelle and also has reduced drag.Type: GrantFiled: July 26, 2011Date of Patent: December 27, 2016Assignee: GE AVIATION SYSTEMS LIMITEDInventor: Michael Fedor Towkan

Patent number: 9242098Abstract: Medical devices are described for performing mapping, ablating, pacing, and/or defibrillating procedures on one or more layers of the cardiac wall via an epicardial or extra-pericardial approach in a minimally invasive (e.g., orthoscopic) surgical procedure. One of the medical devices described includes a main support member and one or more secondary support members extending outwardly from the main support member having electrodes configured to receive electrical impulses. The secondary support member may include a support pad configured to be removably attached to a corresponding area of the epicardium for holding the medical device in place during a procedure, such as through application of vacuum pressure via a containment dome provided on each secondary support member. Further, an ablating electrode may be slidably disposed along the main support member for transmitting energy to a target site proximate the electrode. Other devices and associated methods are also described.Type: GrantFiled: October 30, 2013Date of Patent: January 26, 2016Assignee: THE CHARLOTTE-MECKLENBURG HOSPITAL AUTHORITYInventors: Jeko Metodiev Madjarov, John Michael Fedor, Jackie H.

Publication number: 20110129345Abstract: A propeller blade assembly (1) comprises a plurality of propeller blades (10) each connected to a hub (2) via at least one bearing assembly (3,4). Each of the blades (10) and the bearing assemblies (3,4) is preloaded, wherein the preload is applied over a preload path which includes a blade root portion (11) of each blade (10) and the bearing assemblies (3,4), and a spring (6) is provided in the preload path. In the event of wear of the components of the propeller blade assembly, the spring (6) maintains the preload force. A method of applying the preload to the propeller blade assembly (1) is also disclosed.Type: ApplicationFiled: December 21, 2010Publication date: June 2, 2011Inventor: Michael Fedor Towkan

Publication number: 20060196030Abstract: A first portion or plug and a second portion or pencil are provided, for use in a device, such as a marine engine. The first portion or plug may have an outer surface with external threads and a cavity with internal threads. The external threads of the first portion or plug may be threaded oppositely from the internal threads inside the cavity of the first portion or plug. The opposite threading allows the plug and pencil combination to be detached and unscrewed from an engine without the plug and pencil coming apart.Type: ApplicationFiled: December 15, 2005Publication date: September 7, 2006Inventor: Michael Fedor
