Publication number: 20200397577Abstract: A guidewire may be configured for insertion into a heart of a patient during a procedure such as a transcatheter aortic valve replacement procedure. The guidewire may include a proximal end and a distal end portion. The distal end portion may include (i) a leading section, (ii) a loop structure at a terminal distal end of the guidewire, and (iii) a transition section extending between the leading section and the loop structure. In the absence of applied forces, the leading section is not tangential to the loop structure. With such a configuration, the guidewire may avoid contact with the ventricular septum of the heart when the loop structure is seated within the left ventricle, which may mitigate potential interference with conduction pathways in the ventricular septum, which may in turn mitigate the need for a pacemaker.Type: ApplicationFiled: June 18, 2020Publication date: December 24, 2020Applicant: St. Jude Medical, Cardiology Division, Inc.Inventors: Yousef F.
