20130123911 | TRANSAPICAL COLLAPSIBLE VALVE REFERENCE FIXTURE - A device for positioning a reference element during aortic valve implantation surgery. The device includes a first extension member having a proximal end and a distal end, a connection member adapted to connect the first extension member to a support, and a coupling having a first end connected to the connection member and a second end connected to the proximal end of the first extension member so that the first extension member is moveable in multiple planes relative to the support. At least one reference datum is operatively connected to the distal end of the first extension member and extends in a straight line, the reference datum being moveable between a first position and a second position to enable precise locating of the reference datum during the aortic valve implantation surgery. | 05-16-2013 |
20130295541 | TRANSCATHETER HEART VALVE DELIVERY DEPLOYMENT SIMULATOR - An apparatus for simulation of an anatomical structure may include a left ventricle component having an inlet port configured to receive fluid flow therethrough, an aortic arch component having an outlet port configured to receive fluid flow therethrough, an aortic annulus component attached to and disposed between the left ventricle component and the aortic arch component, and an introducer configured to receive an elongated catheter assembly therethrough. The aortic annulus component may have an inner surface including simulated stenotic nodules. The introducer may be in fluid communication with at least one of the left ventricle component and the aortic arch component. | 11-07-2013 |
20130297009 | AORTIC BANDS AND METHODS OF USE - A method of testing the performance of a collapsible prosthetic heart valve includes wrapping an aortic band around an outer surface of a portion of an aorta, fastening a first end portion of the aortic band to a second end portion of the aortic band, implanting a collapsible prosthetic heart valve in the aorta at an implantation site, and flowing a pressurized fluid through the aorta. The aortic band may be positioned near the sinotubular junction of the aorta. When installed around the aorta, the aortic band reinforces the portion of the aorta so as to be more resistant to radial expansion. | 11-07-2013 |
20140214158 | SURGICAL HEART VALVE FLEXIBLE STENT FRAME STIFFENER - A prosthetic heart valve includes an annular frame having annularly spaced commissure portions and an annulus portion disposed near an inflow edge, a fabric covering at least a portion of the frame and a valve assembly connected to the frame at the commissure portions, the valve assembly including a plurality of leaflets. A stiffening member is disposed about the frame to limit ovalization of the frame when a radial force is applied to the frame. | 07-31-2014 |
20140249564 | Methods of Repositioning a Transcatheter Heart Valve After Full Deployment - A device for repositioning an implant within a lumen of a subject including (a) a catheter having forward and rearward ends and a collapsible and expansible stop element mounted adjacent the forward end of the catheter, the stop element being adapted to engage a wall of the lumen when expanded and to provide one or more passages extending from a rear side of the stop element to a forward side of the stop element when the stop element is expanded and engaged with the wall of the lumen and (b) one or more snares, each snare having engagement features, the stop element and the snares being constructed and arranged so that the snares can be positioned extending through the one or more passages with their engagement features forward of the stop element. | 09-04-2014 |
20140257466 | TRANSCATHETER VALVE REPLACEMENT - A prosthetic heart valve having an inflow end and an outflow end includes a collapsible and expandable stent. A collapsible and expandable valve assembly is disposed within the stent and includes a plurality of leaflets. A collapsible and expandable frame formed of braided wires has a body portion and a lumen extending through the body portion for receiving the stent and the valve assembly. The frame may include features for holding the prosthetic heart valve in place in a patient. | 09-11-2014 |
20140257472 | METHOD OF PREPARING A TISSUE SWATCH FOR A BIOPROSTHETIC DEVICE - A method of preparing a tissue swatch comprising one or more desired thicknesses for use in the manufacture of a bioprosthetic device, said method comprising sectioning a sheet of frozen tissue to produce a tissue swatch of said one or more desired thicknesses. | 09-11-2014 |
20140277407 | SIMULATED ENVIRONMENT FOR TRANSCATHETER HEART VALVE REPAIR - An apparatus for applying liquid pressure to resected tissue may include a fixture, a papillary assembly coupled to the fixture and having first and second spaced apart papillary attachment elements, and a resected mitral valve attached to the fixture. The fixture may have a first chamber, a second chamber, and an internal panel extending between the first and second chambers. The resected mitral valve may be attached to the internal panel and may have a posterior leaflet, an anterior leaflet, and tendinae chordae. The tendinae chordae may each be attached at a first end to the posterior leaflet or the anterior leaflet and at a second end to one of the papillary attachment elements. A first group of the tendinae chordae may be attached to the first papillary attachment element, and a second group of the tendinae chordae may be attached to the second papillary attachment element. | 09-18-2014 |
20140296966 | STENT FEATURES FOR COLLAPSIBLE PROSTHETIC HEART VALVES - A prosthetic heart valve includes a stent having an expanded condition and a collapsed condition. The stent includes a plurality of distal cells, a plurality of proximal cells, a plurality of support struts coupling the proximal cells to the distal cells, and at least one support post connected to a plurality of proximal cells. The proximal cells are longitudinally spaced apart from the distal cells. Various strut configurations and connections of the struts to the proximal cells and of the proximal cells to the support post improve stent flexibility and reduce stress in the valve leaflets. | 10-02-2014 |
20150073538 | ALIGNMENT OF AN IMPLANTABLE MEDICAL DEVICE - A transcatheter valve delivery system includes a longitudinal member extending between a proximal end and a distal end, and having a compartment adjacent the distal end for holding a medical device in a collapsed condition. An alignment element is connected to the longitudinal member and is movable relative to the longitudinal member between a stowed position and a deployed position. In the deployed position, the alignment element is configured to urge against an anatomical surface to position the longitudinal member at a desired location relative to the anatomical surface. | 03-12-2015 |
20150073539 | ALIGNMENT OF AN IMPLANTABLE MEDICAL DEVICE - A medical device delivery system includes an inner shaft having a proximal end and a distal end, a support shaft having a proximal end and a distal end and an articulating assembly disposed between the inner shaft and the support shaft. The support shaft is sized for insertion into the circulatory system of a patient. The articulating assembly includes a first portion at the distal end of the inner shaft and a second portion at the proximal end of the support shaft. The first portion is pivotable relative to the second portion to change orientation of the support shaft relative to the inner shaft. | 03-12-2015 |
