Patent number: 8206432Abstract: A radially expandable stent comprising a plurality of spaced band-like elements and intersecting links is disclosed. The band-like elements have a generally serpentine configuration to provide continuous waves of generally sinusoidal character to each band-like element. The waves are characterized by a plurality of peaks and troughs taking a generally longitudinal direction along the cylinder such that the waves in the band-like elements open as the stent is expanded from a first diameter to a second diameter. The intersecting links are substantially U-shaped and terminate in first and second shanks. The first shank of a link emanates from a region between a peak and trough on a band-like element and the second shank of the link emanates from a region between a peak and trough on an adjacent band-like element.Type: GrantFiled: June 7, 2010Date of Patent: June 26, 2012Assignee: Boston Scientific Scimed, Inc.Inventors: Graig L. Kveen, Timothy G. J. Ehr, Brian J. Brown

Patent number: 8185213Abstract: Some embodiments of an electrical stimulation system employ wireless electrode assemblies to provide pacing therapy, defibrillation therapy, or other stimulation therapy. In certain embodiments, the wireless electrode assemblies may include a guide wire channel so that each electrode assembly can be advanced over a guide wire instrument through the endocardium. For example, a distal tip portion of a guide wire instrument can penetrate through the endocardium and into the myocardial wall of a heart chamber, and the electrode assembly may then be advanced over the guide wire and into the heart chamber wall. In such circumstances, the guide wire instrument (and other portions of the delivery system) can be retracted from the heart chamber wall, thereby leaving the electrode assembly embedded in the heart tissue.Type: GrantFiled: October 22, 2010Date of Patent: May 22, 2012Assignee: Boston Scientific Scimed, Inc.Inventors: Graig L. Kveen, Douglas R. Saholt, Roger Hastings, Richard C. Gunderson
