Patent number: 9737264Abstract: An implantable device system includes an implantable device, such as an annuloplasty ring, for controlling at least a shape and/or size of a heart valve annulus. The implantable device includes an arcuate body and an adjustment system configured to adjust the shape and/or size of the arcuate body. An adjustment tool is configured to be coupled to the adjustment system so that the adjustment tool can be used to activate and control adjustment of the arcuate body. A sensor system is configured to be coupled to the implantable device. The sensor system includes a first sensor configured to measure physiological data at an inflow portion of the valve annulus when the implantable device is implanted into the valve annulus, and a second sensor configured to measure physiological data at an outflow portion of the valve annulus when the implantable device is implanted into the valve annulus.Type: GrantFiled: August 13, 2015Date of Patent: August 22, 2017Assignee: St. Jude Medical, Cardiology Division, Inc.Inventors: Peter N.

Patent number: 9700409Abstract: A prosthetic heart valve may include a stent body with a plurality of cells arranged in circumferential rows and a cuff attached to the stent. A leaflet attachment panel may be attached to and span a portion of one of the cells. A prosthetic valve element, such as a leaflet having a belly, may be mounted to the leaflet attachment panel.

Patent number: 9668857Abstract: A prosthetic heart valve includes a stent body with a generally tubular annulus section, which may include one or more circumferential rows of cells. One or more prosthetic valve elements mounted to the stent body operate to allow blood flow in an antegrade direction but to substantially block flow in a retrograde direction. A cuff is attached to the stent body and positioned on a luminal surface of the stent body. At least one sealing member is attached to the cuff. The sealing member may be patch with an open side facing in a first axial direction and a closed side facing in a second axial direction opposite to the first axial direction. Flow of blood in the second axial direction will tend to force blood into the sealing member and cause the sealing member to billow outwardly relative to the stent body.Type: GrantFiled: September 30, 2014Date of Patent: June 6, 2017Assignee: St. Jude Medical, Cardiology Division, Inc.Inventors: Peter N.
