Publication number: 20160175583Abstract: 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: ApplicationFiled: March 2, 2016Publication date: June 23, 2016Applicant: BOSTON SCIENTIFIC SCIMED, INC.Inventors: GRAIG L. KVEEN, DOUGLAS R. SAHOLT, ROGER N. HASTINGS, RICHARD C. GUNDERSON

Patent number: 8986367Abstract: 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: January 23, 2014Date of Patent: March 24, 2015Assignee: Boston Scientific Scimed, Inc.Inventors: Graig L. Kveen, Timothy G. J. Ehr, Brian J. Brown

Publication number: 20140128969Abstract: An apparatus, system, and method for percutaneous valve replacement and/or augmentation. The apparatus includes a valve having a valve frame, a valve leaflet coupled to the valve frame, and a thread passing over the valve frame to hold the valve frame in a partially deployed state, where removal of the thread allows the valve frame to expand toward a deployed state. Use of the thread to hold the valve frame allows for staged deployment of the valve.Type: ApplicationFiled: January 15, 2014Publication date: May 8, 2014Applicant: Boston Scientific Scimed, Inc.Inventors: Jason P.

Publication number: 20140039591Abstract: Some embodiments of pacing systems employ wireless electrode assemblies to provide pacing therapy. The wireless electrode assemblies may wirelessly receive energy via an inductive coupling so as to provide electrical stimulation to the surrounding heart tissue. In certain embodiments, the wireless electrode assembly may include one or more biased tines that shift from a first position to a second position to secure the wireless electrode assembly into the inner wall of the heart chamber.Type: ApplicationFiled: October 2, 2013Publication date: February 6, 2014Applicant: Cardiac Pacemakers, Inc.Inventors: William J.

Patent number: 8231669Abstract: A tether guided bifurcated stent having a generally tubular main body extending along a longitudinal axis connected to a side branch assembly. Both the main stent body and the side branch assembly are capable of forming an unexpanded configuration and an expanded configuration. The bifurcation's expansion is facilitated by a force exerted by the tether. When the side branch assembly is expanded it forms a secondary tubular region defining a generally tubular shape extending at an angle to the longitudinal axis of the main tubular body.Type: GrantFiled: September 22, 2005Date of Patent: July 31, 2012Assignee: Boston Scientific Scimed, Inc.Inventors: Matthew J.
